daser333 [38]

Answer:

You make $270 every two weeks. Since you pay rent on the first of every month you will have made two paychecks which would equal out to $540.00 a month.. apartments usually run $700 or more a month... So sorry man, you cant afford an apartment. however, you might be able to find one that cheap, but its very very very rare.

What is the rate of change from x = 0 to x = pi over 2?
12345 [234]

Answer:

8/pi

Step-by-step explanation:

To find the rate of change from 0 to pi/2  we need the values at 0 and pi/2

f(0) = -4

f(pi/2) = 0


rate of change = change in f(x)/ change in x

                        = (f(x2) -f(x1))/( x2-x1)

                        = (0--4) / (pi/2 - 0)

                         = (0+4) / (pi/2)

                        = 4 / (pi/2)

                          = 8/pi
