Find the surface area of a square based pyramid if the edge of the base is 8 inches and the slant height is 20 inches.

Surface area of a square based pyramid:

A = base area + lateral surface area

  = side^2 + side x slant height x 1/2 x 4

  = 8^2 + 8 x 20 x 1/2 x 4

  = 384 (in2)

Hope this helps!

:)

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
