Answer:

x = 1

Step-by-step explanation:

4x - 5/5 = 3

4x - 1 = 3

add 1 to each side of the equation:

4x = 4

divide both sides by 4:

x = 1

Answer: The perimeter is 17.52

Step-by-step explanation:

1. You can plot the points, as you can see in the graph attached.

2. As you can see in the graph, the points are:

$A(-2,-2)\\B(-2,3)\\C(2,4)\\D(3,1)\\E(0,-2)$

And the lenghts AB and EA are:

$AB=5$

$EA=2$

3. To find the other lenghts, you can apply the formula for calculate the distance between two points:

$distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

4. Thefore, you have:

$BC=\sqrt{(2-(-2))^{2}+(4-3)^{2}}=4.12\\CD=\sqrt{(2-3)^{2}+(4-1)^{2}}=3.16\\DE=\sqrt{(3-0)^{2}+(1-(-2))^{2}}=4.24$

5. The perimeter is:

$P=AB+CD+DE+EA\\P=5+4.12+3.16+4.24+2\\P=17.52$

MATH HELP PLEASE

Anuta_ua [19.1K]

calculate the slopes of the lines using the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

(x₁, y₁ ) = A(- 4, - 1) and (x₂, y₂ ) = B(-1, 2 )

$m_{AB}$ = $\frac{2+1}{-1+4}$ = $\frac{3}{3}$ = 1

(x₁, y₁ ) = B(-1, 2) and (x₂, y₂ ) = (5, 1)

$m_{BC}$ = $\frac{x1-2}{5+1}$ = - $\frac{1}{6}$

(x₁, y₁) = C(5, 1 ) and (x₂, y₂ ) = D(1, - 3)

$m_{CD}$ = $\frac{-3-1}{1-5}$ = $\frac{-4}{-4}$ = 1

(x₁, y₁) = A(- 4, - 1) and (x₂, y₂) = D(1, - 3 )

$m_{AD}$ = $\frac{-3+1}{1+4}$ = - $\frac{2}{5}$

A little help?? It’s trig

statuscvo [17]

Answer:

12 $\pi$ = 37.699 f/s

Actually, the more interesting question

would have been how fast is the ball going in MPH?

25.7 MPH

Step-by-step explanation:

C = 2 $\pi r$

C = 2 $* \pi * 1.2$

C = 2.4 $\pi feet$

C (per second) = (5)(2.4 $\pi feet$ )

C(per second) = 12 $\pi$ = 37.699 f/s
