This question has missing details. However, I've corrected each question before solving them
Required: Determine the inverse
1:
Replace f(x) with y
Swap y & x
Divide through by 25
Replace y with f'(x)
2.
Replace g(x) with y
Swap y & x
Add 1 to both sides
Make y the subject
3:
Replace h(x) with y
Swap y & x
Add to both sides
Multiply through by -4
Divide through by 9
4:
Replace f(x) with y
Swap y with x
Take 9th root
Replace y with f'(x)
5:
Replace f(a) with y
Swap a with y
Subtract 8
Take cube root
Replace y with f'(a)
6:
Replace g(a) with y
Swap positions of y and a
Solve using quadratic formula:
; ;
becomes
Factorize
7:
Replace f(b) with y
Swap y and b
Open Brackets
Solve using quadratic formula:
; ;
becomes
Factorize:
Replace y with f'(b)
8:
Replace h(x) with y
Swap x and y
Cross Multiply
Subtract x from both sides:
Subtract 2y from both sides
Factorize:
Make y the subject
Replace y with h'(x)
9:
Replace h(c) with y
Swap positions of y and c
Square both sides
Subtract 2 from both sides
Make y the subject
10:
Replace f(x) with y
Swap positions of x and y
Cross Multiply
Subtract y from both sides
Add x to both sides
Factorize
Make y the subject
Replace y with f'(x)
Answer:
its would cost 79 dollars have a good day
Step-by-step explanation:
Answer:
753.982 ft^3
Step-by-step explanation:
Use the fomula for the area of a circle:
4/2=2
2^2=4
4 x pi =12.566 ft ^2
Multiply that by the height of the column:
12.566 x 20=251.327 ft^3
And that by the number of columns:
251.327 x 3=753.982 ft^3
Have a great day, and mark me brainliest if I am most helpful!
