Given f(x)= 4x^4 find f^-1(x) Then state whether f^-1(x) is a function
Answer:
The inverse is
f^-1(x) = (1/√2)x^¼
And it is a function
Step-by-step explanation:
Given f(x) = 4x^4
Let y = f(x), so that
y = 4x^4
Then dividing both sides by 4
x^4 = y/4
Taking the fourth root of both sides
x = (y/4)^¼
x = (1/√2)y^¼ = f^-1(y)
Put y = x
y = (1/√2)x^¼ = f^-1(x)
This is the inverse.
f^-1(x) is a function.

A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the pan?
Answer:
The first choice is correct
Step-by-step explanation:
$32.00 x 15% = 4.80. 32.00-4.80=27.20. Another way to work it is the first choice, subtracting 15% from 100% and then multiplying 85% by $32.00. Same answer

The figure shows the front side of a purse in the shape of a trapezoid.
What is the area of this trapezoid?
110 in²
121 in²
130 in²
220 in²
Answer:
110in2
Step-by-step explanation:
Area = (base1 + base2 ) * height /2
= ( 9 + 13) *10 /2 = 110in2
Answers:
110in^2
Step-by-step explanation:
area pf rectangle=l×w
=9in×10in
=90in^2
area of 1st triangle
A=bh/2
=2in×10in/2
=20in^2/2
=10in^2
area of 2nd triangle=10in^2
Area of trapezoid =90in^2+10in^2+10in^2
=11in^2

A study shows that, over the course of a lifetime, the average salary of college graduates is greater than the average salary of people with only a high school diploma. The results were published claiming that graduating from college ensures you will make more money over the course of your lifetime. What is the problem with reporting results this way?
loaded question
correlation and causality
voluntary response
missing data
Answer:
The problem with reporting this result is:
Missing data.
Step-by-step explanation:
The reason behind this answer is: first of all a loaded question has a bias, the question in our case is arbitrary because it doesn't suggest an inclination of perspective. The correlation between studies and salaries also is not wrong, it is well developed. Therefore, the casualty is well developed. There is no voluntary response because it was not a questionnaire that could have been manipulated. We could have obtained the data from the government database. However, that is what we are lacking. We have no statistics, no source, no institution mentioned, we have missing data.

Can someone help me ASAP? I don’t understand some answers because don’t the trees take in carbon to photosynthesize but won’t the deers also release carbon by cellular respiration?
A herd of deers lives in a forest where they eat the leaves of trees. The number of energy storage molecules in the tress and in the deers has increased. What has happened to the amount of carbon in the trees and in the deer?
The amount of carbon in the trees and in the deer . . .
A) has increased.
B) has decreased.
C) has not changed.
D) is not related to the number of energy storage molecules.
Answer:
a
Step-by-step explanation:
it makes sence for the answer to be a because
Answer:
The amount of carbon in the trees and in the deer . . .
A) has increased.
Explanation:
Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.
Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.
