Determine the surface area from the folllowing nets. Type the answer in the space provided (no units needed). If the answer is correct a mystery picture will appear. (Zo om in for bigger picture of dimensions)

#1

Surface area is the sum of 3 rectangles and 2 triangles:

S = 8*6 + 9*6 + 8*3 + 2(1/2*3*6) = 144 ft²

#2

Surface area is the sum of 1 square and 4 triangles:

S = 5*5 + 4*(1/2*3*5) = 55 ft²

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

f(-2) = -3f(1) = 6 . . . estimated from f(x) = (x+2)^2-3, which matches points on the graph (-1,-2) and (0, 1)

so the change in y-value for function f is (6 )) = 9.

the table tells us

g(-2) = 1g(1) = 31

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

Its d so thats how it would would back from 1.0 form three four two
