Answer:
2.9%
Step-by-step explanation:
The problem says the stations are 260 feet apart. Assuming that this is the horizontal distance between them, then the grade is:
7.5 / 260 × 100% = 2.9%
This is less than the maximum of 3.5%, so it meets the standards.
The function f(x) = x2 - 6x + 9 is shifted 5 units to the left to create g(x). What is
g(x)?
Answer:
g(x) = x^2 + 4x + 4
Step-by-step explanation:
In translation of functions, adding a constant to the domain values (x) of a function will move the graph to the left, while subtracting from the input of the function will move the graph to the right.
Given the function;
f(x) = x2 - 6x + 9
a shift 5 units to the left implies that we shall be adding the constant 5 to the x values of the function;
g(x) = f(x+5)
g(x) = (x+5)^2 - 6(x+5) + 9
g(x) = x^2 + 10x + 25 - 6x -30 + 9
g(x) = x^2 + 4x + 4
Find the radius of a circle with circumference of 45.84 meters. Use 3.14
Answer:
3.8 meters
Step-by-step explanation:
In order to find the circumference for a circle, we use the formula π(radius)²
The circumference give is 45.84 and the π given is 3.14
All we have to do is to just substitute them.
45.84 = 3.14(radius)²
45.84 / 3.14 = radius²
14.6 = radius²
radius = √14.6
radius = 3.82 ≅ 3.8
Answer:
approx. 7.3 m
Step-by-step explanation:
The formula for the circumference of a circle is s = r·Ф, where r is the radius and Ф is the central angle in radians.
Here C = 45.84 m = 2π·r. Solving for the radius, r, we get:
45.84 m
r = --------------- = 7.299 m, or approx. 7.3 m.

Suppose at one point along the Nile River a ferryboat must travel straight across a 1.40-mile stretch from west to east. At this location, the river flows from south to north with a speed of 2.35 m/s. The ferryboat has a motor that can move the boat forward at a constant speed of 21.8 mph in still water. In what direction should the ferry captain direct the boat so as to travel directly across the river?
Answer:
about 14° south of east
Step-by-step explanation:
The river speed is about ...
(2.35 m/s)×(1 mi/(1609.344 m))×(3600 s)/(1 h) ≈ 5.2568 mi/h
The angle of interest is such that its sine is the ratio of river speed to boat speed:
sin(α) = (5.2568 mi/h)/(21.8 mi/h) = 0.241138
α = arcsin(0.241138) = 13.9537°
Since the river is flowing north, the boat should be directed south of its intended course by this angle.
The boat should be directed 14° south of east.
To counteract the effect of the river current, the boat should be directed slightly upstream. The specific direction can be calculated using trigonometric relationships between the boat's velocity and the river's velocity.
Explanation:In order to answer this question, one must understand the basic concepts of vectors and relative velocity in physics. These concepts are essential in determining the correct direction for the ferry captain to steer the boat.
To make the journey directly across the river, the captain needs to counteract the effect of the south-to-north current. This essentially means that the boat should be directed slightly upstream. Applying basic physics concepts, the velocity of the boat relative to the ground (or the river bank) is the sum of the boat's velocity relative to the river (21.8 mph toward the east) and the river's velocity (2.35 m/s to the north).
The direction to aim can be obtained by using trigonometric relationships. The direction is tan^-1((2.35 m/s)/(21.8 mph in m/s)) to the north of east. Note that you need to convert 21.8 mph to m/s before solving.

there are 96 marbles in a box. There are 5 times as many blue marbles as red marbles. How many red marbles are there?
Answer:
16
Step-by-step explanation:
96 marbles = Box
Let's call blue marbles " 5 x " and red marbles " x "
So now an equation is setup ⇒
→ 5 x + x = 96
( Simplify )
→ 6 x = 96
( Divide by 6 from both sides to isolate x )
→ x = 16
red marbles " x " so x = 16
You would use the following equation:
96 = 5x + x
There is a total of 96 marbles. The right side of the equation represents how many blue marbles are in the box. X is red marbles in the box, since we know that red marbles is 5 times x
Add the common variables:
96 = 5x + x
96 = 6x
To solve for red marbles isolate x. To do this divide 6 to both sides. Division is the opposite of multiplication and will cancel 6 from the right side and bring it to the left
96 ÷ 6 = 6x ÷ 6
16 = x
You have 16 marbles in the box

g = 15 - (m/32)If Vera stars with a full tank of gas, the number of gallons of gas g, left in the tank after driving m miles is given by the equation above. When full, how many gallons of gas does Vera's tank hold?15 gallons.17 gallons.32 gallons.480 gallons
ANSWER
15 gallons
EXPLANATION
The equation that models the situation is
[tex]g(m) = 15 - \frac{m}{32} [/tex]
When the tank was full the man did not cover any mile.
To find the the number of gallons of gases Vera's tank holds, we substitute m=0 into the equation to get,
[tex]g(0) = 15 - \frac{0}{32} = 15[/tex]
Therefore the correct answer is is option A 15 gallons
Final answer:
When Vera's tank is full, it holds 15 gallons of gas. This is found by setting the miles driven to zero in the equation g = 15 - (m/32).
Explanation:
To determine how many gallons of gas Vera's tank holds when full, we need to set m, the number of miles driven, to zero in the given equation g = 15 - (m/32). This is because we are interested in the initial amount of gas before any driving occurs.
Plugging m = 0 into the equation gives us:
g = 15 - (0/32)
g = 15
Therefore, when full, Vera's tank holds 15 gallons of gas. Among the provided options, the correct answer is 15 gallons.
The coordinates of point A on a coordinate grid are (−2, −3). Point A is reflected across the y-axis to obtain point B and across the x-axis to obtain point C. What are the coordinates of points B and C?
A) B(2, 3) and, C(−2, −3)
B) B(−2, −3) and C(2, 3)
C)B(2, −3) and C(−2, 3)
D) B(−2, 3) and C(2, −3)
Answer:
B) B(2,-3) and C(-2,3)
Step-by-step explanation:
The given point A, has coordinates (-2,-3).
When point A(-2,-3) is reflected over the y-axis to obtain point B, then the coordinates of B is obtained by negating the x-coordinate of A.
Therefore B will have coordinates (2,-3).
When point A(-2,-3) is reflected over the x-axis to obtain point C, then the coordinates of C is obtained by negating the y-coordinate of A.
Hence the coordinates of C are (-2,3)

The greater of two consecutive integers is 7 less than one-third the smaller integer. Find the integers and show your work.
Answer:
{-12, -11}
Step-by-step explanation:
Let x represent the smaller of the two integers. The problem statement tells us ...
x +1 = (1/3)x -7
(2/3)x = -8 . . . . . . subtract 1/3x +1
x = -12 . . . . . . . . . multiply by 3/2
The integers are -12 and -11.
Final answer:
To find two consecutive integers where the greater is 7 less than one-third the smaller, we defined the smaller integer as x and set up an equation: x + 1 = (x/3) - 7. Solving through algebraic operations, we found the integers to be -12 and -11.
Explanation:
To solve for two consecutive integers where the greater is 7 less than one-third the smaller integer, let us denote the smaller integer as x and the greater as x + 1. According to the problem, the greater integer (x + 1) is 7 less than one-third the smaller integer (x/3). Thus, we can set up the equation:
x + 1 = (x/3) - 7
To solve for x, we perform the following steps:
Multiply all terms by 3 to eliminate the fraction: 3(x + 1) = x - 21.
Distribute the 3: 3x + 3 = x - 21.
Combine like terms: 2x = -24.
Divide both sides by 2: x = -12.
Now that we have found the smaller integer to be -12, the greater integer is just one more, so it is -11.
Therefore, the two consecutive integers are -12 and -11.

The problem statement asks for an expression for the rug area "based on the width of the room." Looking at the answer choices, we see that the variable "w" is used to represent the width of the room.
The dimensions of the room are its width (w) and its length, which is 5 more than its width (w+5).
The dimensions of the rug are 4 ft smaller in each direction (2 ft on each side), so the width of the rug is w-4, and the length of the rug is w+5-4 = w+1.

We have the product of 2 complex numbers
[tex](2-5i)(p+q)(i)[/tex]
We know that:
[tex]p=2\\\\q=5i[/tex]
Then we substitute these values in the expression
[tex](2-5i)((2)+(5i))(i)[/tex]

Trevor tutors French for $15 and hour and scoops ice cream for $10 an hour. He is going to work 15 hours this week. At least how many hours does he need to tutor to make more than $180? Let x equal the number of hours he tutors and y be the number of hours he scoops ice cream.
Options (you can pick more than one):
x + y = 15
x + y > 15
x + y < 15
15x + 10y = 180
15x + 10y > 180
15x + 10y < 180
So far all I have it the fourth option (15x + 10y = 180).
Answer:
Actually, what you said you have so far is not correct. The 2 correct answers are the 1st one (x + y = 15) and the 5th one (15x + 10y > 180)
Step-by-step explanation:
If tutoring French is x hours and scooping ice cream is y hours and he is going to work 15 hours for sure doing both, then we can add them together to get that x hours + y hours = 15 hours, or put simply: x + y = 15.
Now we are going to throw in the added fun of the money he makes doing each. The thing to realize here is that we can only add like terms. So looking at the equation above, we have x hours of tutoring and y hours of scooping, so if we want to add them, we will add those number of hours together to get the total number of hours he worked, which we know to be 15. The same goes for money. If we add money earned from tutoring to money earned from scooping, we need that to be greater than the money he wants to earn which is 180 at least. Because he wants to earn MORE than $180. we use the ">" sign. Since he earns $15 an hour tutoring, that expression is $15x; since he earns $10 an hour scooping, that expression is $10y. Now add them together (and you CAN because they are both expressions relating dollars to dollars) and set the sum > $180:
$15x + $10y > $180. That's why your answer is not correct. Use mine (with the understanding that you care about why yours is wrong and mine is correct) and you'll be fine.
A company issues auto insurance policies. There are 900 insured individuals. Fifty-four percent of them are male. If a female is randomly selected from the 900, the probability she is over 25 years old is 0.43. There are 395 total insured individuals over 25 years old. A person under 25 years old is randomly selected. Calculate the probability that the person selected is male.
Answer:
about 0.53
Step-by-step explanation:
54% of the insured, or .54×900 = 486 individuals are males. That leaves 900-486 = 414 that are females. 43% of those, or .43×414 = 178 are over 25, so the remainder of the 395 who are over 25 are male.
Since 395 -178 = 217 of the males are over 25, there are 486 -217 = 269 who are under 25. Then the fraction of insureds who are under 25 that are male is ...
269/(900 -395) = 269/505 ≈ 0.53
_____
It can be useful to make a 2-way table from the given information.
Final answer:
Using the provided data, the probability that a person under 25 years old selected randomly is male is calculated by dividing the number of males under 25 (found by subtraction from total males and males over 25) by the total number of individuals under 25.
Explanation:
The question asks us to calculate the probability that a person under 25 years old, selected randomly from a group of insured individuals, is male. To find this, we need to use the given data:
Total insured individuals: 900
Percentage of males: 54%
Individuals over 25 years old: 395
Probability that a randomly selected female is over 25: 0.43
To calculate the number of males and females, we take 54% of 900 to get the total males, which is 486. Since there are 900 insured individuals in total, the number of females would be 900 - 486 = 414. The number of females over 25 years old is 414 * 0.43 = 178.02, which we can round to 178.
Since there are 395 individuals over 25 years old in total and 178 of them are female, 395 - 178 gives us 217 males over 25 years old. Now, we need to find the number of individuals under 25 years old. There are 900 - 395 = 505 individuals under 25.
The probability that a randomly selected person under 25 is male can be found by dividing the number of males under 25 by the total number of people under 25. The number of males under 25 is the total number of males minus males over 25, which is 486 - 217 = 269. Therefore, the probability is 269 / 505.

Problem 12 is 112° and problem 13 is 68°
Step-by-step explanation:
Angles EPF and DPG are vertical angles; therefore, they are congruent. That means, algebraically, that
4x + 48 = 7x
Solving for x:
48 = 3x and x = 16
Now that we know the value of x we can sub it back into the expression for the angle:
4(16) + 48 = 112.
For problem 13, angles DPE and EPF are supplementary, so that means that they add up to equal 180 degrees. Therefore, 180 - 112 = 68 degrees.

Dan buys a car for £2700.
It depreciates at a rate of 1.4% per year.
How much will it be worth in 5 years?
Give your answer to the nearest penny where appropriate.
The car, which depreciates at an annual rate of 1.4%, will be worth approximately £2590.34 in 5 years.
Explanation:This is a problem related to depreciation, which is a concept in finance and economics. In this case, the car depreciates at a rate of 1.4% per year. This means that each year, the value of the car decreases by 1.4% of its value at the start of that year. This is an example of exponential decay.
To calculate the car's value after 5 years, we raise the depreciation rate (99.6%, or 0.996 in decimal form because the value decreases) to the power of 5, and then multiply it by the initial price of the car, £2700.
That is, Car Value = £2700 * (0.996)^5 = £2590.34
So, the car will be worth approximately £2590.34 in 5 years to the nearest penny.

Which inequality best represents that ice cream at −5°C is cooler than ice cream at 4°C?
-5°C < 4°C
An object that is cooler, or colder, than a second object means that the first object has a lower, or lesser, temperature than the second object. So, we write the inequality that states that -5°C is less than 4°C.
Answer:
The answer for this question would be 4°C > −5°C

A marketing firm tracks data on grocery store visits. In one study, it finds that the probability that a shopper buys bread during a visit to the grocery store is 0.70, and the probability that a shopper buys cheese is 0.20.Event A = A shopper buys bread.Event B = A shopper buys cheese.A and B are independent events if _____.
Answer:
Option B.
Step-by-step explanation:
Two events are said to be independent of each other, if the probability of one event ocurrin in not way affects the probability of the other event occurring.
The interception of two independent events P(A ∩ B) = P(A) × P(B), where:
P(A) = 0.70
P(B) = 0.20
P(A ∩ B) = P(A) × P(B) = 0.70x0.20 = 0.14
The two events are independent if the probability of buying Bread AND cheese equals: 0.14, which is Option B.
Answer:
B
