Answer:
678.24 cubic in.
Step-by-step explanation:
Ok, first find the area of the base.
3.14×3^2= 28.26
Then multiply that area by the height, which is 8×3=24
24×28.26=678.24
Let me know if you got it!
Answer:
4 ± 1/2sqrt(x) = y
This is not a function
Step-by-step explanation:
f(x) = (8-2x)^2
y = (8-2x)^2
To find the inverse function, exchange x and y and then solve for y
x = (8-2y)^2
Take the square root of each side
±sqrt(x) = 8-2y
Subtract 8 from each side
-8±sqrt(x) = 8-8-2y
-8±sqrt(x) = -2y
Divide by -2
-8/-2± 1/2sqrt(x) = -2/-2y
4 ± 1/2sqrt(x) = y
This is not a function
3 15/16. ( I hope you know how to write it)
