What is the equation of the line, in point slope form, that passes through the points (4,8) and (2,-2)

Solnce55 [7]

Answer:

Step-by-step explanation:

1) point slope form is:

y-y1=m(x-x1)

y1=8

x1=4

m=(slope)

to find m: y2-y1/x2-x1

hence

-2-8/2-4=-10/-2=5

m=5:

y-8=5(x+4)

Abdul is creating a cushion that is 1 foot by 2 feet by 3 feet. He wants to find the least amount of fabric he will need to cove

netineya [11]

Answer:

The least amount of fabric are 22 square feet

Step-by-step explanation:

we know that

The surface area of a rectangular prism is given by the formula

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

Let

L ---> the length pf the prism

W ---> the width of the prism

H ---> is the height of the prism

Let

$L=2\ ft\\W=3\ ft\\H=1\ ft$

Find the area of the base

$B=LW=(2)(3)=6\ ft^2$

Find the perimeter of the base

$P=2(L+W)=2(2+3)=10\ ft$

Find the surface area

$SA=2(6)+10(1)=22\ ft^2$

therefore

The least amount of fabric are 22 square feet
