2. graph the function d sh, which gives the approximate distance d in miles to the horizon, (l p where h is the height of the viewer's eyes above the ground in feet. approximately how high above the ground must a person be if the horizon is 17.2 miles away?

in measuring distance you must measure your height of eye, the distance bteween the ground and your eyes in meters or feet. Which in your case is the 95,000 feet. Multiply that by 1.5, then take the square root of that answer and you get d= the distance you can see to the horizon.

Perimeter = 35
2(L + W) = 35
L + W = 35/2
w = 35/2 - L

Area(A) = L * W
= L(35/2 - L)
A = (35/2)L - L^2

When Length = 13 cm (Say, L1)
Area = 58.5 cm^2 = A1

When Length = 16cm (Say, L2)
Area = 24 = A2

Average rate of decrease of Area = (A2 - A1)/(L2 - L1)
= -11.5 cm^2 / cm
