What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?

Akimi4 [234]

Answer:

25.6 units

Step-by-step explanation: From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).

First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

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

where

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

- For AB:

d=\sqrt{[1-(-5)]^{2}+(4-4)^2}

d=\sqrt{(1+5)^{2}+(0)^2}

d=\sqrt{(6)^{2}}

d=6

- For BC:

d=\sqrt{(3-1)^{2} +(-4-4)^{2}}

d=\sqrt{(2)^{2} +(-8)^{2}}

d=\sqrt{4+64}

d=\sqrt{68}

d=8.24

- For AC:

d=\sqrt{[3-(-5)]^{2} +(-4-4)^{2}}

d=\sqrt{(3+5)^{2} +(-8)^{2}}

d=\sqrt{(8)^{2} +64}

d=\sqrt{64+64}

d=\sqrt{128}

d=11.31

Next, now that we have our lengths, we can add them to find the perimeter of our triangle:

p=AB+BC+AC

p=6+8.24+11.31

p=25.55

p=25.6

We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.

HELP WILL MARK BRAINLIEST

Crank

Answer:

180

Step-by-step explanation:

1. Write a proportion.

$\frac{6}{2\\}$ = $\frac{x}{60}$

2. Cross multiply.

6x60=360

360/2=180

x=180

1. Write a proportion.

$\frac{6}{2}$ = $\frac{x}{60}$

If you look at the bottom, since 2 times 30 is 60, 6 times 30 is 180, making the fractions equal.

Which Exponential function has a initial and child value of 2

fredd [130]

For an exponential function the y-intercept is the "initial value" (not the common ratio).

$y = 2 \times {1}^{x}$

will always be 2. if that's what you need

note that

${1}^{0} = 1$

because anything to the power of zero equals 0 (mathematically it's deciding something by itself)
