The perimeter is 20 units

Step-by-step explanation:

The end-point of a side of square can be used to calculate length of a side. And the side will be used to calculate the perimeter.

Given

(3,-1) and (7,2)

Let

(3,-1) = (x1,y1)

(7,2) = (x2,y2)

We have to calculate the distance

The formula for distance is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let s be the side of a square

then,

$s=\sqrt{(7-3)^2+(2-(-1))^2}\\s=\sqrt{(4)^2+(2+1)^2}\\=\sqrt{16+(3)^2}\\=\sqrt{16+9}\\=\sqrt{25}\\=5\ units$

The side of square is 5 units. Then,

$Perimeter=P=4s\\=5*4\\=20\ units$

The perimeter is 20 units

The formula for the area of a triangle is a = bh, where b is the length of the base and h is the height. the equation solved for

Marina CMI [18]

Actually, the area of a triangle is a = bh/2. If a = 30 and b = 12:
$30 = \frac{12h}{2}$
$30=6h$
$h=5$
So he height is 5 units

Ben is going bowing this weekend. It will cost $5 for the shoe rental plus $6 per game bowled. Which equation models the cost, c

elena-14-01-66 [18.8K]

Answer:

C(g) = 5 + 6g

Step-by-step explanation:

Let

C be the cost function for Ben

and

g be the number of games

As the shoe rental is paid for all the games, it will be added only once. The variable on which the cost will be dependent is g. The number of games will directly affect the cost function. Here g is independent variable.

So, mathematically writing,

C(g) = 5 + 6g

What is the volume? __ cubic feet

Hunter-Best [27]

Answer:

128 ft³

Step-by-step explanation:

Volume of a prism is the area of the base times the height:

V = Ah

In the case of a triangular prism:

V = (1/2 bh) (L)

Given b = 8 ft, h = 4 ft, and L = 8 ft:

V = 1/2 (8 ft) (4 ft) (8 ft)

V = 128 ft³
