Answer: 90 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a rectangular prism =area of the base x length  

Area of the base is the area of a triangle:

Area of a triangle = base x height x 1/2

Replacing with the values given:

A = 4 x 3 x 1/2 = 6 in2

Back on the volume formula:

V = A x h = 6 x 15 = 90 cubic inches

Find an equation in slope intercept form of the line that has a slope of -8 and passes through point A (1,5)
ollegr [7]

Answer:

8x+y-13=0

Step-by-step explanation:

let the given point be

A(1,5)=(x1,y1)

slope(m)= -8

then,equation of straight line is,

(y-y1)=m(x-x1)

(y-5)= -8(x-1)

y-5= -8x+8

8x+y-5-8=0

therefore,8x+y-13=0 ..........(i) is the required equation.
