Answer:
f^-1(x) = 1/5x + 1/5
Step-by-step explanation:
Switch the x and y values:
y = 5x - 1
x = 5y - 1
Put the equation back into y = form:
x = 5y - 1
x + 1 = 5y
1/5x + 1/5 = y
y = 1/5x + 1/5
f^-1(x) = 1/5x + 1/5
Answer:
I don't think you gave the options, but I can simplify and solve it.
1/2(4 + 8x) = 17
2 + 4x = 17
<u>If you want it simplified:</u> 2 + 4x = 17
Subtract 2 from each side:
2 - 2 + 4x = 17 - 2
4x = 17 - 2
4x = 15
Divide each side by 4:
4x ÷ 4 = 15 ÷ 4
x = 3 and 3/4
<u>If you want to solve for x:</u> x = 3 and 3/4
Given:
Consider the dimensions of a rectangular prism are 4 in by 3 in by 10 in.
To find:
The length of the diagonal.
Solution:
Length of diagonal of a rectangular prism is:
Where l is length, b is breadth and h is height.
The dimensions of a rectangular prism are 4 in by 3 in by 10 in. So, the length of diagonal of the rectangular prism is:
Approximate the value to the nearest tenth.
Therefore, the length of diagonal of the rectangular prism is 11.2 in.
Answer:
The answer to your problem is B.
