The answer is:
[tex]FirstCarSpeed=41mph\\SecondCarSpeed=55mph[/tex]
Why?To calculate the speed of the cars, we need to write two equations in order to create a relation between the two speeds and be able to isolate one in function of the other.
So, let be the first car speed "x" and the second car speed "y", writing the equations we have:
For the first car:
[tex]x_{FirstCar}=x_o+v*t[/tex]
For the second car:
We know that the speed of the second car is the speed of the first car plus 14 mph, so:
[tex]x_{SecondCar}=x_o+(v+14mph)*t[/tex]
Now, we already know that both cars met after 2 hours and 45 minutes, meaning that positions will be the same at that moment, and the distance between A and B is 264 miles, so, we can calculate the relative speed between them.
If the cars are moving towards each other the relative speed will be:
[tex]RelativeSpeed=FirstCarSpeed-(-SecondCarspeed)\\\\RelativeSpeed=x-(-x-14mph)=2x+14mph[/tex]
Then, since from the statement we know that the cars covered a combined distance which is equal to 264 miles of distance in 2 hours + 45 minutes, we have:
[tex]2hours+45minutes=120minutes+45minutes=165minutes\\\\\frac{165minutes*1hour}{60minutes}=2.75hours[/tex]
Writing the equation, we have:
[tex]264miles=(2x+14mph)*t\\\\264miles=(2x+14mph)*2.75hours\\\\2x+14mph=\frac{264miles}{2.75hours}\\\\2x=96mph-14mph\\\\x=\frac{82mph}{2}=41mph[/tex]
So, we have that the speed of the first car is equal to 41 mph.
Now, substituting the speed of the first car in the second equation, we have:
[tex]SecondCarSpeed=FirstCarSpeed+14mph\\\\SecondCarSpeed=41mph+14mph=55mph[/tex]
Hence, we have that:
[tex]FirstCarSpeed=41mph\\SecondCarSpeed=55mph[/tex]

ANSWER
[tex]16\pi \: sq.in[/tex]
EXPLANATION
The area of a sector is calculated using the formula,
[tex]Area = \frac{arc \: measure}{360 \degree} \times \pi {r}^{2} [/tex]
The arc measure is given as 45°
The radius of the circle is 8 inches.
We substitute to obtain,
[tex]Area = \frac{45 \degree}{360 \degree} \times \pi \times {8}^{2} [/tex]
[tex]Area = \frac{1}{4} \times 64\pi = 16\pi[/tex]
The answer is:
The correct option is the second option:
[tex]SectorArea=8\pi in^{2}[/tex]
Why?To answer the question, we need to calculate the total area of the circle (which corresponds to 360°) and then, calculate the equivalent area to the sector of the arc that measures 45°
Calculating the total area, we have:
[tex]TotalArea=\pi radius^{2} \\\\TotalArea=\pi 8^{2} =64\pi in^{2}[/tex]
Now, we need to consider that the calculated area (total area) correspondes to all 360° that conforms the interior angle of a circle, now, if we want to calculate the area that represents a sector of the arc that measures 45°, we have to use the following formula:
[tex]SectorArea=\frac{360\°}{45\° }*TotalArea\\\\SectorArea=\frac{45\°}{360\° }*64\pi in^{2}=\frac{1}{8} *64\pi in^{2}\\\\SectorArea=8\pi in^{2}[/tex]
Hence, we have that the correct option is the second option:
[tex]SectorArea=8\pi in^{2}[/tex]

You received a bill for $82.53. You prepaid on a budget plan for $110.00/ mth. How much was your original bill?
Answer:
192.53= original bill
Step-by-step explanation:
The bill you receive is equal to the original bill minus the prepaid amount
bill = original - prepaid
82.53 = original - 110
Add 110 to each side
82.53+110 = original-100+100
192.53= original bill
If the translation maps point (3,2) to (4,5); or T: (3,2) —> (4,5), then what is the image of point (0,0)? (4,5) (-1,-3) (1,3)
Answer:
(1, 3)
Step-by-step explanation:
If the translation is ...
(3, 2) + (a, b) = (4, 5)
Then we can find (a, b) by subtraction:
(4, 5) -(3, 2) = (a, b) = (4-3, 5-2) = (1, 3)
Not the image of point (0, 0) will be ...
(0, 0) + (a, b) = image
(0, 0) + (1, 3) = (0+1, 0+3) = (1, 3)
The image of the point is (1, 3).

.
.
Answer:
b ≈ 3.1
Step-by-step explanation:
The law of sines tells you ...
b/sin(B) = c/sin(C)
Here, you have to find angle C based on the sum of the angles of a triangle being 180°.
C = 180° - A - B = 180° - 69° - 32° = 79°
Multiplying the above law of sines equation by sin(B), you have ...
b = c·sin(B)/sinc(C) = 5.7·sin(32°)/sin(79°) ≈ 3.07707
b ≈ 3.1 . . . . . rounded to tenths
Answer:
[tex]\displaystyle 3,1 ≈ b[/tex]
Step-by-step explanation:
First, find [tex]\displaystyle m∠C,[/tex]accourding to the Triangle-Sum Theorem:
[tex]\displaystyle 180° = 32° + 69° + m∠C \hookrightarrow 180° = 101° + m∠C; 79 = m∠C[/tex]
Now that we have all three angles, we can solve for edge b
[the second edge], using the Law of Sines:
[tex]\displaystyle \frac{c}{sin∠C} = \frac{b}{sin∠B} = \frac{a}{sin∠A} \\ \\ \frac{5,7}{sin\:79°} = \frac{b}{sin\:32°} \hookrightarrow 3,0770743283... = \frac{5,7sin\:32°}{sin\:79°} \\ \\ 3,1 ≈ b[/tex]

The yearly attendance at a ballpark is shown in the table. Which answer describes the average rate of change from Year 2 to Year 5?
Answer:
A
Step-by-step explanation:
The average rate of change is the change in attendance over change in time.
Δy / Δx
(333.7 - 298.3) / (5 - 2)
11.8
So the average rate of change is an increase of 11.8 thousand people per year.
The average rate of change from Year 2 to Year 5 is 11.8 if at year 2 the attendance is 298.3 and at year 5 the attendance is 333.7
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
We have to find the average rate of change from Year 2 to Year 5:
At year 2 the attendance = 298.3
At year 5 the attendance = 333.7
Average rate of change = (333.7-298.3)/(5-2)
= 11.8
Thus, the average rate of change from Year 2 to Year 5 is 11.8 if at year 2 the attendance is 298.3 and at year 5 the attendance is 333.7

HELP i’m having trouble with my homework assignments
Answer:
Collin: about $401 thousand
Cameron: about $689 thousand
Step-by-step explanation:
A situation in which doubling time is constant is a situation that can be modeled by an exponential function. Here, you're given an exponential function, though you're not told what the variables mean. That function is ...
[tex]P(t)=P_0(2^{t/d})[/tex]
In this context, P0 is the initial salary, t is years, and d is the doubling time in years. The function gives P(t), the salary after t years. In this problem, the value of t we're concerned with is the difference between age 22 and age 65, that is, 43 years.
In Collin's case, we have ...
P0 = 55,000, t = 43, d = 15
so his salary at retirement is ...
P(43) = $55,000(2^(43/15)) ≈ $401,157.89
In Cameron's case, we have ...
P0 = 35,000, t = 43, d = 10
so his salary at retirement is ...
P(43) = $35,000(2^(43/10)) ≈ $689,440.87
___
Sometimes we like to see these equations in a form with "e" as the base of the exponential. That form is ...
[tex]P(t)=P_{0}e^{kt}[/tex]
If we compare this equation to the one above, we find the growth factors to be ...
2^(t/d) = e^(kt)
Factoring out the exponent of t, we find ...
(2^(1/d))^t = (e^k)^t
That is, ...
2^(1/d) = e^k . . . . . match the bases of the exponential terms
(1/d)ln(2) = k . . . . . take the natural log of both sides
So, in Collin's case, the equation for his salary growth is
k = ln(2)/15 ≈ 0.046210
P(t) = 55,000e^(0.046210t)
and in Cameron's case, ...
k = ln(2)/10 ≈ 0.069315
P(t) = 35,000e^(0.069315t)

30 24 The data shows the number of years that 30 employees worked for an insurance company before retirement.(blank) is the population mean for the number of years worked, and(blank) % of the employees worked for the company for at least 10 years. (Round off your answers to the nearest integer.)
Answer:
years worked: 14
at least 10 years: 73%
Step-by-step explanation:
The mean is found by adding the years of service and dividing by the number of employees. The total years of service is 417, so the average is ...
average years worked = 417/30 = 13.9 ≈ 14 . . . years
__
The percentage of employees that have worked there at least 10 years is found by counting the number with 10 or more years of service and dividing that count by the total number of employees. The result is then expressed as a percentage.
(10 years or over)/(total number) = 22/30 = 0.73_3 (a repeating decimal) ≈ 73%
_____
Comment on the working
A spreadsheet can be helpful for this. It has a function that can calculate the mean for you. Sorting the years of service into order can make it trivially easy to count the number that are 10 or more, or you can write a function that will do the count for you. (Also, less than 10 means the years are a single digit. There are 8 single-digit numbers in your list.) The hard part is copying 30 numbers without error.
The answers are: 14 years and 50%. 14 years is the population mean for the number of years worked, and 50 % of the employees worked for the company for at least 10 years.
To determine the answers, steps:
1. Calculate the Population Mean: Sum all the years worked and divide by the number of employees (30).
[tex]Total\ years\ worked: 8 + 13 + 15 + 3 + 13 + 28 + 4 + 12 + 4 + 26 + 29 + 3 + 10 + 3 + 17 + 13 + 15 + 15 + 23 + 13 + 12 + 1 + 14 + 14 + 17 + 16 + 7 + 27 + 18 + 24 = 412[/tex]
[tex]Population\ mean =\frac{412}{30} \approx 14[/tex]
2. Calculate the Percentage of Employees who Worked At Least 10 Years: Count the employees who worked for 10 years or more, and divide by the total number of employees, then multiply by 100 to convert to percentage.
[tex]Number\ of\ employees\ who\ worked\ at\ least\ 10\ years: 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 15[/tex]
[tex]Percentage = \frac{15}{30} * 100 = 50\%[/tex]
Help me with ixl please
Answer:
$33.00
Step-by-step explanation:
You find out how much the sale price is by subtracting 25% of 40 from 40:
40 - [(.25)(40)] and that equals 30. So the sale price is $30. Now if the tax is 10% (.1 in decimal form), we find the total cost by adding .1(30) to 30:
30 + [(.1)(30)] which is $33
Which measurement is the measure of an obtuse angle?
Answer: An obtuse angle is any angle greater than 90° and less than 180°
Step-by-step explanation:
Answer:
An obtuse angle is more than 90 degrees so anything above 90 degrees is obtuse while anything below is either an acute, strait, or right angle.
Step-by-step explanation:
The function f(x) = square root of x is translated left 5 units and up 3 units to create the function g(x)
what is the domain of G(x)?
{x | x > –5}
{x | x > –3}
{x | x > 3}
{x | x > 5}
Answer:
The domain of g(x) is {xI x > -5} ⇒ first answer
Step-by-step explanation:
* Lets talk about the transformation at first
- If the function f(x) translated horizontally to the right
by h units, then the new function g(x) = f(x - h)
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
* lets revise the meaning of the domain
- The domain is all values of x that make the function defined
- Find the values of x which make the function undefined
- The domain will be all the real numbers except those values
* Now we can solve the problem
∵ f(x) = √x
- f(x) translated 5 units to the left, then add x by 5
∴ f(x) ⇒ f(x + 5)
- f(x) translated 3 units up, then add f(x) by 3
∴ f(x) ⇒ f(x) + 3
- The function g(x) is created after the transformation
∴ g(x) = f(x + 5) + 3
∵ f(x) = √x
∴ g(x) = √(x + 5) + 3
- The function will be defined if the value under the square root
is positive (means greater than 0)
∵ The expression under the square root is x + 5
∴ x + 5 > 0 ⇒ subtract 5 from both sides
∴ x > -5
- The domain will be all the real numbers greater than -5
∴ The domain of g(x) is {xI x > -5}
The domain of the function g(x), which is the function f(x) = square root of x translated left 5 units and up 3 units, is {x | x > -5}.
The original function f(x) has a domain of {x | x ≥ 0} because we cannot take the square root of a negative number. When the function is translated left 5 units, the new function, g(x), will start at x = -5 instead of x = 0, reflecting the domain shift due to translation. Therefore, the domain of g(x) is {x | x > -5}.

The square of a number equals to The product of 32 and that number
We can conclude that the correct answer is c The square of a number is equal to the product of 32 and that number.
HELP! Solve for x. Make sure to show your work and provide complete geometric explanations.
Answer:
For a. [tex]x=7[/tex]
For b. [tex]x=2[/tex]
Step-by-step explanation:
To solve this, we are using the intersecting secants theorem. The theorem says that if two secant segments intersect a circle from an exterior point, then the product of the measures of the exterior segment and the whole secant is equal to the product of the measures of the other exterior segment and its whole secant.
Applying this to our circles:
For a.
[tex]5(5+x)=6(6+4)[/tex]
[tex]25+5x=6(10)[/tex]
[tex]25+5x=60[/tex]
[tex]5x=60-25[/tex]
[tex]5x=35[/tex]
[tex]x=\frac{35}{5}[/tex]

[tex]16+4x=24[/tex]
[tex]4x=8[/tex]
[tex]x=\frac{8}{4}[/tex]

1. What are the mean, median, mode and range of the data set given the altitude of lakes in feet: -12,-9,-14,-39,-49,-18, and -43?
2. Given the data 21,13,13,37,13,23,25,15:
a. What is the outlier in the data?
b. What is the mean with the outlier?
c. What is the mean without the outlier?
First put your numbers in order from least to greatest (These are negative numbers so that means that the smallest number is the one farthest away from zero)
-49, -43, -39, -18, -14, -12, -9
Mean is adding all the numbers together and dividing the sum by how many numbers there are in the data set
-49 + (-43) + (-39) + (-18) + (-14) + (-12) + (-9) = -184
There are seven numbers so divide -184 by 7:
-184 ÷ 7 ≈ 26.29
Median is the number in the middle. Take away the smallest number and the biggest number on each layer until you get to the middle
-49, -43, -39, -18, -14, -12, -9
-43, -39, -18, -14, -12
-39, -18, -14
-18 <-------------------Median
Mode is whatever number appears the most often in the data. In this case all the numbers appear only once so there is no mode
Range is subtracting the largest number by the smallest number
-9 - (-49) = 40
2. Data in order
13, 13, 13, 15, 21, 23, 25, 37
Outlier is the number that is a number that is rather far from the other number in the data
a. In this case the outlier is 37
b. 13 + 13 + 13 + 15 + 21 + 23 + 25 + 37 = 160
160 ÷ 8 = 20
c. 13 + 13 + 13 + 15 + 21 + 23 + 25 = 123
123 ÷ 7 = 17.57

Step-by-step explanation:
Mean = -49 + (-43) + (-39) + (-18) + (-14) + (-12) + (-9) = -184
There are seven numbers so divide -184 by 7:
-184 ÷ 7 ≈ 26.29
Median =
-49, -43, -39, -18, -14, -12, -9
-43, -39, -18, -14, -12
-39, -18, -14
-18
Mode =
-9 - (-49) = 40
2.
13, 13, 13, 15, 21, 23, 25, 37
Outlier is the number that is an odd number
a. In this case the outlier is 37
b. 13 + 13 + 13 + 15 + 21 + 23 + 25 + 37 = 160
160 ÷ 8 = 20
c. 13 + 13 + 13 + 15 + 21 + 23 + 25 = 123
123 ÷ 7 = 17.57

the height in feet of a ball dropped from a 150 ft building is given by h(t)=-16 ft^2 +150, where t is the time in seconds after the ball is dropped. find h(2) and interpret its meaning. round your answer to the nearest hundredth.
A. h(2)=86.00 means that after 2 seconds, the height of the ball is 86.00 ft.
B. h(2)=3.04 means that after 2 seconds, the height of the ball has dropped by 3.04 ft
C. h(2)= 3.04 means that after 2 seconds, the height of the ball is 3.04 ft
D. h(2)= 86.00 means that after 2 seconds, the height of the ball has dropped by 86.00 ft.
Answer:
Part 1) Option A. h(2) = 86.00 means that after 2 seconds, the height of the ball is 86.00 ft
Step-by-step explanation:
we have
[tex]h(t)=-16t^{2}+150[/tex]
where
t ----> is the time in seconds after the ball is dropped
h(t) ----> he height in feet of a ball dropped from a 150 ft
Find h(2)
That means ----> Is the height of the ball 2 seconds after the ball is dropped
Substitute the value of t=2 sec in the equation
[tex]h(2)=-16(2)^{2}+150=86\ ft[/tex]
therefore
After 2 seconds, the height of the ball is 86.00 ft.

Jared is building a treehouse. He pays $75 for materials and pays his friend $12 per hour to help him. If Jared spends a total of $129 on building his tree house, for how many hours did his friend work on it?
Answer:
I think the answer is 4.5 if you subtract 75 from 129 and divide by 12?
After deducting the cost of materials, the remaining amount spent on labor was $54. By dividing this amount by the friend's hourly rate of $12, it is determined that Jared's friend worked for 4.5 hours on constructing the treehouse.
Jared is trying to calculate how many hours his friend worked on building a treehouse based on the total cost of the project. Jared spent $75 on materials and paid his friend $12 per hour for labor. The total cost for building the treehouse was $129.
To find out how many hours Jared's friend worked, we start by subtracting the cost of materials from the total cost:
Total cost of treehouse = $129
Cost of materials = $75
Total cost minus materials cost = $129 - $75 = $54
This $54 represents the total amount paid for labor. We can then divide this amount by the hourly rate to find the number of hours worked:
Hourly wage = $12
Labor cost / hourly wage = $54 / $12 = 4.5 hours
Therefore, Jared's friend worked for 4.5 hours on the treehouse.

sin E =
Whats the answer
B is correct. I’ve noticed that you’ve posted a lot of questions like this, so here’s how I remember it. Soh-Cah-Toa
Soh stands for Sin=Opposite (the side opposite to the angle) over hypotenuse (the side opposite to the right angle)
Cah stands for Cos=Adjecent (the side next to the angle that is not the hypotenuse) over the hypotenuse
Toa stands for Tan=opposite over adjacent
Good luck! Hope I helped you understand.
