Answer:
The constant of proportionality is 2.50
Step-by-step explanation:
For a weight of 1 lb, the price is $2.50, so the price in dollars is related to the weight in pounds by the constant 2.50.
The constant of proportionality is 2.50 (dollars per pound).
If your functions are
f(x) = 16·x
g(x) = 16·(1/2x)
The output values of g(x) are one-half the output values of f(x) for the same value of x.
If your functions are
f(x) = 16^x
g(x) = 16^(1/2x)
The output vaules of g(x) are the square root of the output values of f(x) for the same value of x.

Answer:
3280 square inches
Step-by-step explanation:
The surface area of square pyramid = 4* the area of the triangular side + the area of the square base.
TRIANGULAR SIDE
The pyramid has an isosceles triangular side of size, a=40 inches, b= 29 inches, c = 29 inches.
Surface area = sqrt{ s(s-a)(s-b)(s-c) }
Where s= (a+b+c)/2
S= (40+29+29)/2 = 49
Surface area = sqrt{ 49(49-40)(49-29)(49-29)}
Surface area = 420 square inches
SQUARE BASE
Area of a square = a²
Area = 40² = 1600 square inches
Surface area of the pyramid = 4*420 + 1600 = 1680 + 1600
Surface area = 3280 square inches.
