x(1/2)-5
Step-by-step explanation:
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

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours
Step-by-step explanation:
All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.
Part 1: Garden Snail
= [tex]\frac{2,800}{0.029}[/tex]
≈ 96,551.7
Part 2: North American X-15
= [tex]\frac{2,800}{4,520}[/tex]
≈ 0.6
These are the answer!

Estimate a 15% tip on a dinner bill of $81.66 by first rounding the bill amount to the nearest ten dollars.
Answer:
12 dollars
Step-by-step explanation:
Round the bill to the nearest ten dollars
81.66 rounds to 80 dollars
80 * 15%
80 *.15
12
The tip is 12 dollars
Answer:
81.66/100*115 = 93.909 rounding down to $90
Step-by-step explanation:
Simplify the following expression. x^1/3*x^1/5
---------------------------------------------------
x^1/3*x^1/5
Apply exponent rule:
x^1/3*x^1/5= x^1/3+1/5
x^1/3+1/5
Add the fractions:
LCM of 3, 5 is 15
5/15 + 3/15
Since the denominators are equal combine the fractions:
5+3/15

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.

Find the volume of the composite figure below:
5 in
8 in
6 in
10 in
Answer:
716in³
Step-by-step explanation:
The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.
For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about 235.62 cubic inches.
For the volume of the other prism, we simply have to do length times height times width, or 6·8·10. That is equal to 480 cubic inches, which is the volume of that prism.
To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.
235.62+480= 715.62in³, or about 716in³.
Hope this helps.
