Use this graph to write an explicit function to represent the data and determine how much money Amy earned in week 5.

A. f(n) = 5(3)^n + 1; f(5) = 3,645

B. f(n) = 5(3)^n; f(5) = 1,215

C. f(n) = 5(3)^n - 1; f(5) = 405

D. f(n) = 3(3)^n - 1; f(5) = 81​

The y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

To find the y-intercept of  f⁻¹(x), we can start by finding the inverse function f⁻¹(x) first.

Let y = f(x) = 3/4 x + 12

To find f⁻¹(x), we can first swap x and y, and then solve for y:

x = 3/4 y + 12

x - 12 = 3/4 y

4/3 (x - 12) = y

Therefore, f⁻¹(x) = 4/3 (x - 12)

The y-intercept of f⁻¹(x) is the value of f⁻¹(x) when x = 0.

f⁻¹(0) = 4/3 (0 - 12)

= -16

Hence, the y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

Answer:

Area of the top = 24 square inch

Step-by-step explanation:

Volume of the given prism = Area of the base or top of the prism × Height of the prism

By substituting the values in the formula,

312 = Area of the top × 13

Area of the top = [tex]\frac{312}{13}[/tex]

Area of the top = 24 square inch

Step-by-step explanation:

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode. Therefore if you look at the chart you can see that one more people get 8 than 9, 10, or 5.

Answer:

RP = 8

Step-by-step explanation:

RQ + QP = RP (segment addition theorem)

(x + 1) + 7 = 2x + 8 (substitution)

Add like terms

x + 8 = 2x + 8

8 - 8 = 2x - x

0 = x

x = 0

✔️RP = (x + 1) + 7

Plug in the value of x

RP = (0 + 1) + 7

RP = 1 + 7

RP = 8

Answer:

Dylan delivered 140 parcels on Wednesday.

Step-by-step explanation:

On Wednesday:

On Wednesday, he delivered x parcels.

Thursday:

10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x

Friday:

50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.

THis is equals to 77. So

[tex]0.5*1.1x = 77[/tex]

[tex]x = \frac{77}{0.5*1.1}[/tex]

[tex]x = 140[/tex]

Answer:

1,007,760

Step-by-step explanation:

This is a question that bothers on selection

Using the combination formula

nCr  = n!/(n-r)!r!

20C12 = 20!/(20-12)!12!

20C12 = 20!/8!12!

20C12 = 20*19*18*17*16*15*14*13*12!/8!12!

20C12 = 20*19*18*17*16*15*14*13/8!

20C12 = 20*19*18*17*16*15*14*13/8*7*6*5*4*3*2

20C12 = 5,079,110,400/5040

20C12 = 1,007,760

Hence this can be done 1,007,760 different ways

Answer:

17/15 _53/6

Step-by-step explanation:

The other is problem 1 and the other is problem 2

PROBLEM #1:

As the problem is, we are adding a negative. I can change this to be a subtraction problem. It looks like this: [tex]2\frac{1}{3} - 1\frac{1}{5}[/tex].

To be able to add or subtract fractions/mixed numbers, we have to first get common denominators. A common denominator is a shared multiple between two numbers. So, we need to find the smallest number that both 3 and 5 (the denominators of each fraction) can do into evenly. In this case, that number is 15! To transform the fractions to have common denominators, we will multiply 1/3 by 5/5 and 1/5 by 3/3 (multiply the top and bottom by 5 or 3 so that the denominator is 15). Here is our new problem: [tex]2\frac{5}{15} - 1\frac{3}{15}[/tex].

All that's left to do now is subtract! Since our first fraction is larger (this is important!) we don't need to do any borrowing. So, we'll subtract 2 - 1 = 1, and 5/15 - 3/15 = 2/15. Therefore, if we put those pieces back together, we get 1 2/15 ([tex]1\frac{2}{15}[/tex]).

PROBLEM #2:

For this problem, we have two negative mixed numbers. In this case, we will simply be adding the negative numbers because both are negative. For example, -2 + -4 = -6. Here is the rewritten problem: [tex]-3\frac{1}{2} + -5\frac{1}{3}[/tex].

Our first step is to get common denominators. In this case, that common denominator will be 6: [tex]-3\frac{3}{6} + -5\frac{2}{6}[/tex].

Now, we have to add! -3 + -5 = -8, -3/6 + -2/6 = -5/6. Once we've added the parts, we can put them back together to form the answer: -8 5/6 ([tex]-8\frac{5}{6}[/tex]).

Answer:

$4.875 Rounded to nearest cent:$4.88

Step-by-step explanation:

50%=0.50

3.25*0.50=1.625

$3.25+$1.625=$4.875

The rule is five or more add one more. So add one to the 7 making it 8. Make sure to take out the five. And you get $4.88

Answer:

$6.50

Step-by-step explanation:

(I submitted and it was right)

3.25 = 50%

3.25 + 3.25 = 6.50

6.50 = 100%

Answer:

2× 14 is 28 and that's the perimeter of the rectangle

Answer:

A =L×W

Given,

A=6x²-9x

W=3x

Substituting into the main equation

6x²-9x=L×(3x)

3x(2x-3)=L×(3x)

divide both sides by 3x

2x-3=L

L=2x-3

I saw on your other question that you mention y (0) = 0. Let

f(x, y) = x + y ²

Now consider the recurrences in Euler's method,

[tex]\begin{cases}x_0=0\\x_n=x_{n-1}+h&\text{for }n>0\end{cases}[/tex]

[tex]\begin{cases}y_0=y(x_0)=0\\y_n=y_{n-1}+f(x_{n-1},y_{n-1})h&\text{for }n>0\end{cases}[/tex]

where h is the step size.

We then approximate y (0.2) in ...

• ... 2 steps for h = 0.1 :

[tex]\begin{cases}x_0=0\\y_0=0\end{cases}[/tex]

[tex]\begin{cases}x_1=x_0+0.1=0.1\\y_1=y_0+f(x_0,y_0)\times0.1=0\end{cases}[/tex]

[tex]\begin{cases}x_2=x_1+0.1=0.2\\y_2=y_1+f(x_1,y_1)\times0.1=0.01\end{cases}[/tex]

so that y (0.2) ≈ 0.01;

• ... 4 steps for h = 0.05 :

[tex]\begin{cases}x_0=0\\y_0=0\end{cases}[/tex]

[tex]\begin{cases}x_1=x_0+0.05=0.05\\y_1=y_0+f(x_0,y_0)\times0.05=0\end{cases}[/tex]

[tex]\begin{cases}x_2=x_1+0.05=0.1\\y_2=y_1+f(x_1,y_1)\times0.05=0.0025\end{cases}[/tex]

[tex]\begin{cases}x_3=x_2+0.05=0.15\\y_3=y_2+f(x_2,y_2)\times0.05=0.0075003125\end{cases}[/tex]

[tex]\begin{cases}x_4=x_3+0.05=0.2\\y_4=y_3+f(x_3,y_3)\times0.05=0.0150031252343798828125[/tex]

so y (0.2) ≈ 0.015.

Answer:

the slope is -2x

Step-by-step explanation:

Its negative because the line is going towards the negatives, and 2 because the slope is rise over run. the line is going up 2 and over 1, which means 2/1, which simplifies to 2

Answer:

-2x -2

Step-by-step explanation:

The slope is negative because it is going down instead of up

y intercept is -2

Use rise over run

Rise is y x is run select 2 points and check rise/run

Slope= - x -(y)
