Area of Base = 28in^2

Area of prism = 280 in^3

Step-by-step explanation:

Area of a trapezoid:

{(a+b)/2}*h            a and b are the bases

Plug in the formula to the information:

{(9+5)/2}*4

(14/2)*4

7*4

28 in^2

Now multiply by 10 for the prism (it is 10 in tall):

28*10=280 in^3

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
