Find the volume of the solid of revolution formed by rotating the bounded region about the x-axis.
f(x)=e-x, y=0, x=-2, x=1.

27.11514 pi

Step-by-step explanation:

Given is a function exponential as

The region bounded by the above curve, y =0 , x=-2 x =1 is rotated about x axis.

The limits for x are -2 and 1

The volume when rotated through x axis is found by

Here a = -2 and b =1

volume =

=

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
