When Jeremy filled his car's gas tank last week, his car had an odometer reading of 25,500. One week later, he refilled the tank, which now has an odometer reading of 26,100. It took 25 gallons of gas to fill the tank. How many miles does Jeremy's car get per gallon?
24 miles is the answer.
Step-by-step explanation:
The previous reading of Jeremy's car = 25500
The current reading is = 26100
Difference between readings = [tex]26100-25500=600[/tex]
Number of gallons used to fill the tank = 25
So, miles traveled by Jeremy in 25 gallons is = 600
In 1 gallon, he travels = [tex]\frac{600}{25}= 24[/tex] miles.
Therefore, Jeremy's car gets 24 miles per gallon.
Describe the translation (Picture provided)
Answer:
D
Step-by-step explanation:
We would need to understand 2 rules of translation in order to figure this out.
1. The graph of f(-x) is the graph of f(x) reflect about the y-axis
2. The graph of f(x+a) is the graph of f(x) shifted horizontally a units LEFT and the graph of f(x-a) is the graph of f(x) shifted horizontally a units RIGHT
We are comparing [tex]ln(5-x)[/tex] with the parent graph of [tex]lnx[/tex]. Firstly, there is -x in place of x, this means the graph is reflected about y-axis. Next, there is +5 added with -x, so it means the graph is shifted horizontally 5 units to the LEFT
Looking at the answer choices, D is the correct answer.
Answer:
Option d
Step-by-step explanation:
Let f(x) be a logarithmic function of the form [tex]f(x) = log(x)[/tex]. So:
[tex]y = f(-x)[/tex] represents a reflection of f(x) on the y axis.
[tex]y = f(-x) = log(-x)[/tex]
Then:
[tex]y = f(x + 5)[/tex] represents a displacement of [tex]f(x)[/tex] 5 units to the left.
[tex]y = f(x + 5) = log(x + 5)[/tex]
Therefore, the operation:
[tex]y = f(-x + 5) = log(5-x)[/tex]
Represents a reflection on the y axis and a translation of 5 units to the left

In the year 2000, the United States had a population of about 281.4 million people; by 2010, the population had risen to about 308.7 million.
Part A
Find the 10-year continuous growth rate using P=[tex]P_{0}[/tex][tex]e^{rt}[/tex].
Part B
Write an equation to model the population growth of the United States, and use it to estimate the population in 2020.
Answer:
Part 1. 0.9259 % per year
Part 2. P = 281.4e^(0.009 259t); 338.6 million
Step-by-step explanation:
Data:
P₀ = 281.4 million
P = 308.7 million
Part 1. Growth rate
t = 2010 - 2000 = 10 yr
P = P₀e^(rt)
308.7 = 281.4e^(10r)
e^(10r) = 1.0970
10r = ln1.0970
r = (ln1.0970)/10 = (0.092 59)/10 = 0.009 259
r = 0.9259 % per year
The 10-year continuous growth rate is 0.9259 % per year.
Part 2. Population model
The population model is
P = 281.4e^(0.009 259t)
where P is in millions and t is the number of years since 2000.
By 2020,
P = 281.4e^(0.009 259 × 20) = 281.4e^0.1852 = 281.4 × 1.203
P = 338.6 million
The estimated population in 2020 is 338.6 million.
What is the domain of the function f(x)= e^x/e^x+c if c is a constant greater than 0
Answer: Option d.
Step-by-step explanation:
To find the domain of the function we should look for the values for which the denominator is equal to zero, because the division by zero is not allowed.
We know by definition that the function [tex]e^x[/tex] is always greater than zero for all x.
We know that the constant c is greater than zero (c>0).
Then, the expression [tex]e^x+c[/tex] is never equal to zero.
Therefore, it does not exist a value for x that makes the denominator 0. Then, the domain of the function is all real numbers.
The answer is the option d.
5 apples cost ?1.45. 3 apples and 2 bananas cost ?1.13. What is the cost of 1 banana
1.45÷5=0.29
0.29×3=0.87
1.13-0.87=0.26
0.26÷2=0.13
One banana costs 0.13
Final answer:
By setting up two equations based on the cost of apples and the combined cost of apples and bananas, we can calculate that the cost of one banana is \'0.13.
Explanation:
To solve the question about the cost of one banana, we need to set up two equations based on the given information. Let's denote the cost of one apple as 'A' and the cost of one banana as 'B'.
We are given that 5 apples cost \'1.45, which can be written as an equation: 5A = 1.45. We are also given that 3 apples and 2 bananas cost \'1.13, which can be expressed as the equation 3A + 2B = 1.13. By solving these two equations simultaneously, we can find the value of 'B', the cost of one banana.
First, we solve the first equation for A: A = 1.45/5. We get A = 0.29. Now, we substitute this value into the second equation: 3(0.29) + 2B = 1.13. This simplifies to: 0.87 + 2B = 1.13. Solving for B, we get: 2B = 1.13 - 0.87, hence B = (1.13 - 0.87)/2. After performing the subtraction and division, we find that B = 0.13.
Therefore, the cost of one banana is \'0.13.

A dress costs $63. If the store is having a 20% off sale how much does the dress cost now
The dress will cost $50.40 after a 20% discount from the original price of $63. You calculate this by finding 20% of $63, which is $12.60, and subtracting it from $63.
Explanation:When a store is having a 20% off sale, it means that the original price of the item is reduced by 20%. In this case, you need to calculate 20% of $63, which is the original price of the dress.
To find 20% of $63, you multiply 63 by 20/100 (because percent means per hundred). That is: 63 * 0.20 = $12.60.
So the amount of the discount is $12.60. Therefore, you subtract this discount from the original price of the dress to find out the new price: 63 - 12.60 = $50.40.
So, after a 20% off sale, the dress will cost $50.40.

A carpenter has a board 18 1/2 feet long. He needs to cut as many 1 3/4 feet long pieces as possible. How many pieces can the carpenter cut? Explain how you found your answer.
So you know that the carpenter has a board that is 18.5ft long and he wants to cut 1.75ft pieces.
Assume that x is the amount of boards he cuts,
1.75x = 18.5
Isolate x by dividing each side by 1.75.
x = 18.5/1.75 = 10.57 pieces.
What is the value of f(?3) +f(7) f(-3) +f(7) when f(x)=?3x+9 f(x)=-3x+9 ? 18 6 -6 -12
Answer:
The correct answer is 6.
Step-by-step explanation:
To find this, first find f(-3)
f(x) = -3x + 9
f(-3) = -3(-3) + 9
f(-3) = 9 + 9
f(-3) = 18
Now we do the same for f(7)
f(x) = -3x + 9
f(7) = -3(7) + 9
f(7) = -21 + 9
f(7) = -12
Now we add them together
18 + -12 = 6
The value of f(?3) + f(7) - f(-3) + f(7) is -24.
Explanation:To find the Value of f(?3) + f(7) - f(-3) + f(7), we need to substitute the given values into the function f(x) = -3x + 9.
Substituting -3 for x, we get f(?3) = -3(-3) + 9 = 18.
Substituting 7 for x, we get f(7) = -3(7) + 9 = -12.
Substituting -3 for x and adding the results, we get f(-3) = -3(-3) + 9 = 18.
Substituting 7 for x, we get f(7) = -3(7) + 9 = -12.
Now, let's calculate the Value of the expression:
f(?3) + f(7) - f(-3) + f(7) = 18 + (-12) - 18 + (-12) = -24

The kite is made of two triangles. Are they isoscele, equilateral, or scalene triangles?
A kite's symmetrical structure typically forms isosceles triangles due to equal side lengths. Asymmetrical kites generate scalene triangles with varying side lengths, influencing triangle types and angles within based on side intersections.
A kite, with its distinct shape formed by two pairs of adjacent congruent sides, generates triangles within. These triangles can exhibit various properties based on the kite's symmetry. If the kite is symmetrical, the triangles formed tend to be isosceles due to the equal side lengths.
However, asymmetrical kites can yield scalene triangles with sides of varying lengths. The relationship between the kite's structure and the triangle types arises from the lengths and intersections of its sides.
Symmetry tends to create similar or congruent triangles, while asymmetry leads to triangles with differing side lengths. Consequently, the angles within these triangles vary based on the intersection of the kite's sides, resulting in a mix of acute, obtuse, or right angles.

Find all polar coordinates of point P = (9, 75°).
Answer:
1) (9, 75+360n)
2) (−9, 255+360n)
Step-by-step explanation:
(9, 75) is same as (9, 75 + 360)
so it would be (9, 435)
It can also be expressed as (-9, 75 + 180 degrees)
so (-9,255) degrees
In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)
Answer with explanation:
The Position of Point in two dimensional plane , P=(9,75°)
→The general rule of writing the point (r,Ф) in terms of polar coordinates is,
x=r cos Ф , y=r sin Ф
The angle between Intial side and terminal side is Acute.
Here, r=9 units
And , Ф=75°
→→Period of Cosine and Sine is 2π.
⇒⇒So,the coordinates of Point will be
x=9 *cos (2nπ+75°), And ,y=9 *sin (2nπ+75°), where n is any integer.
Write a polynomial expression, in simplified form, that represents the AREA of the blanket and use the expression to evaluate the AREA of the blanket if x = 2.
Answer:
Polynomial expression that represents the area of blanket:
[tex]A(x)=(6x^2+5x-21)cm^2[/tex]
If [tex]x=2[/tex]: [tex]A(2)=13cm^2[/tex]
Step-by-step explanation:
The area of the rectangle can be calculated with the formula:
[tex]A=lw[/tex]
Being l the lenght of the rectangle and w the width of the rectangle.
In this case, the lenght and the width are represented with:
[tex]l=(3x+7)cm[/tex]
[tex]w=(2x-3)cm[/tex]
Substitute them into [tex]A=lw[/tex]:
[tex]A(x)=(3x+7)(2x-3)[/tex]
Then:
Use Distributive property (Remember the Product of powers property: [tex]b^a*b^c=b^{(a+c)}[/tex] ):
[tex]A(x)=(3x+7)(2x-3)\\A(x)=6x^2-9x+14x-21[/tex]
Add like terms:
[tex]A(x)=(6x^2+5x-21)cm^2[/tex] (Simplied form)
Evaluate [tex]x=2[/tex]:
[tex]A(2)=(6(2)^2+5(2)-21)cm^2\\A(2)=(6(4)+10-21)cm^2\\A(2)=(24-11)cm^2\\A(2)=13cm^2[/tex]

Step-by-step explanation:
What is the remainder R when the polynomial p(x) is divided by (x+2)
Answer:
see explanation
Step-by-step explanation:
If (x + 2) is a factor then x = - 2 is a root and p(- 2) = 0
p(- 2) = -4[tex](-2)^{4}[/tex] + 6(- 2)³ + 8(- 2)² + 2(- 2) - 1
= - 64 - 48 + 32 - 4 - 1 = - 85
Hence remainder R = - 85
Since p(- 2) ≠ 0 then (x + 2) is not a factor of p(x)
