The figure below is a diagram of a trapezoidal table that needs to be stained. Each can of stain will cover 50 square inches.
alekssr [168]

The perimeter is the sum of the outside dimensions.

b1 = 87 - 32 - 14 - 13 = 28 in.

Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.

Divide area by the amount 1 can covers:

360 / 50 = 7.2 cans, round up to 8 cans are needed.

Find an equation for these points (-5,5) (4,2)
user100 [1]

Answer:

\large\boxed{y=-\dfrac{1}{3}x+\dfrac{10}{3}}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (-5, 5) and (4, 2).

substitute:

m=\dfrac{2-5}{4-(-5)}=\dfrac{-3}{9}=-\dfrac{1}{3}

Put the value os a slope and coordinates of the point (4, 2) to the equation of a line:

2=-\dfrac{1}{3}(4)+b

2=-\dfrac{4}{3}+b             <em>add 4/3 to both sides</em>

2\dfrac{4}{3}=b\to b=3\dfrac{1}{3}\to b=\dfrac{10}{3}
