The temperature (in degrees Celsius) as a function of time (in hours since noon) for a certain day in San Jose, Costa Rica, is graphed. What is the approximate average rate at which the temperature decreases between 3{:}30\text{ pm}3:30 pm3, colon, 30, start text, space, p, m, end text and 8{:}30\text{ pm}8:30 pm8, colon, 30, start text, space, p, m, end text?

use formula for the circle a=3.14

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
