Answer:
The recursive function gives the total number of pictures Angela will have painted at any day in the future is:
PP(t) = t + [tex]\frac{4}{7}t[/tex]The number of pictures will she have painted if she paints for another 5 days after the initial week is:
18.86Step-by-step explanation:
To obtain the recursive function, you must take into account the next:
1. Angela paints 4 pictures in 7 days, by this, you can say Angela paints 4/7 of a picture by day.
2. Angela paints additional 1 picture by day, with this, the number of pictures painted additionally is equal to the time t (because 1 day = 1 picture, 2 days = 2 pictures and so on). With the data taken into account, we can elaborate the next function:
PP(t) = t + [tex]\frac{4}{7}t[/tex]Where:
PP: Painted pictures.t: time in days.For example, if you need to know how many pictures she painted in the first week, you can calculate replacing t by 7:
PP(t) = t + [tex]\frac{4}{7}t[/tex] PP(7) = 7 + [tex]\frac{4}{7}*7[/tex]PP(7) = 7 + 4PP(7) = 11If she paints for another 5 days (I mean 12 days taking into account the initial week), we can calculate:
PP(t) = t + [tex]\frac{4}{7}t[/tex] PP(12) = 12 + [tex]\frac{4}{7}*12[/tex]PP(12) = 12 + [tex]\frac{48}{7}[/tex]PP(12) = [tex]\frac{132}{7}[/tex]PP(12) = 18.86To the day 12, Angela will paint 18.86 pictures.
Answer:
The recursive function that gives the total number of pictures she will have painted at any day in the future is
next = now + 1, starting at 4 , and the total number of pictures after a week plus 5 days is 9.

If you vertically compress the absolute value parent function, f(x) = [X1, by a
factor of 5, what is the equation of the new function?
O A g(x) = [x - 51
B. g(x) = 1x1
C. g(x) = 5|X1
D. g(x) = (5x1
Answer:
your answer should be C.
Step-by-step explanation:
brainliest?
The transformation of the parent function f ( x ) = | x | by a compression of 5 units is given by g ( x ) = ( 1/5 ) | x |
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the parent function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = | x | be equation (1)
On simplifying , we get
when the function is stretched vertically by a factor , we get
Vertical stretch by a factor k: y = k × f(x)
And , when it is compressed by a factor of k = 5 units
The transformed function is g ( x ) = ( 1/5 ) | x |
Hence , the transformed function is g ( x ) = ( 1/5 ) | x |

The TV measures 39 inches tall, and the length of its diagonal is 80 inches. What is the width of the TV? Round your answer to the nearest tenth and label your answer.
Your answer:
We're assuming the TV is a rectangle, meaning all corners have right angles.
From the given information, we have a right triangle with a height of 39 inches, hypotenuse, of 80 inches, and an unknown base width.
Using Pythagorean's theorem:
[tex]a^2+b^2=c^2[/tex]
[tex]b=\sqrt{c^2-a^2}[/tex]
c = 80 and a = 39
[tex]b=\sqrt{80^2-39^2}[/tex]
[tex]=\sqrt{4879}[/tex]
Using a calculator and rounding to the nearest tenth gives

8x – 4y = 16
8x + 4y = 16
x= ___
y= ___
PLS HELP
Answer:
x =2, y =0
Step-by-step explanation:
First we can add the equations to get rid of the y terms in each.
Adding them results in 16x = 32
Dividing by 16 gives us x=2
Substituting this back into equation 1 gives us 8(2) -4y =16
Simplifying,
16 - 4y =16
-4y = 0
y = 0

Answer:

Step-by-step explanation:
It's one or the other, so the two on the graph won't connect, and each of them are greater/less than, NOT "or equal to" so both the circles would be closed. When thinking of these, forget about the x and just read greater than 5. On a graph the greater numbers are to the right, so the arrow would be pointing that way

You did not provide a list of equations for us to select from.
Let me see if I can put together.
Distance = rate times time (in hours).
Let x = time of the trip in hours.
D = rx
Let D = 295 miles.
Let r = 65 mph.
Here is your equation: 295 = 65x
