The distance s (in feet) a moving car is from a stoplight is given by the following function. s(t) = 15t3/2 Find the average speed of the car from t1 = 0 to t2 = 9 seconds.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

i think the length is 12 and the width is 17
