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
[tex]\approx 69.8 \text{ inches}[/tex]

Which type of interest can be described as interest that is earned on the principal amount only
Simple interest is the type of interest that is earned on the principal amount only.
What is Interest?Interest in simple terms is the extra amount that you have to pay if you borrow money or the extra money you get if you lend the money.
Simple interest is one of the type of interest.
Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Suppose that, a certain transaction has an annual interest rate of 2% for a period of 10 years.
If the principal amount is P, then in simple interest, interest will be a fixed amount, that is, 2% of P, in the whole period.
In compound interest, the interest will be compounded each of the year or month or quarterly depending on the criterion.
Hence the type of interest described here is simple interest.

Find the measure of the indicated arc
Step-by-step explanation:
We know that if an arc subtends an angle of theta , with a radius r , then the measure of arc is r× theta . Here theta is 109° .

Max has a collection of 99 dimes and pennies worth $4.41. How many pennies does he have?
Answer:
61 pennies
Step-by-step explanation:
d + p = 99
0.1d + 0.01p = 4.41
d = 99 - p
0.1(99 - p) + 0.01p = 4.41
9.9 - 0.1p + 0.01p = 4.41
-0.09p = -5.49
p = 61
Answer: 61 pennies

An oatmeal container has a diameter of 20 cm and can hold 1570 cm3 of oatmeal. What is the height of the container of oatmeal
Answer:
5 cm approx
Step-by-step explanation:
Given data
Diameter= 20cm
radius= 10cm
Volume= 1570cm^3
We know that the expression for the volume of the container/cylinder is
V= πr^2h
1570= 3.142*10^2*h
1570=3.142*100*h
1570=314.2h
h= 1570/314.2
h=4.99 cm
Hence the height is 5 cm approx

Sharif drove 295 miles from St. Louis to Detroit at an
average speed of 65 mph. Which equation can be
used to find the time of the trip (x) in hours?
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
