Answer: see below

<u>Step-by-step explanation:</u>

Speed = | Velocity |

Velocity -14 20 -2 0 25 -15

Speed 14 20 2 0 25 15

Velocity -16 16

Speed 16 16

3 is greater then -4

|---------|---------|

-4 0 3

A velocity of -4 has a greater speed than a velocity of 3

Velocity -4 3

Speed 4 3

Find the surface area of the solid formed by the net. Round your answer to the nearest hundredth.

-BARSIC- [3]

Answer:

<h2>The area of the total figure is around 535.43 square centimeters.</h2>

Step-by-step explanation:

In the image attached, you can notice that all rectangles have a base of 20 centimeters.

Also, each side of the equilaterals triangles is 8 centimeters.

Notice that the height of each rectangle is equal to a side of a triangle.

Using all given vales, the area of each rectangle is

$A_{rectangle}=b\times h=20 \times 8 =160 cm^{2}$

The area of all rectangles is

$A_{rectangles}=3(160cm^{2})=480 cm^{2}$ , because there are three rectangles in total.

The area of each triangle is

$A_{triangle }=\frac{\sqrt{3} }{4} (8cm)^{2} =\frac{\sqrt{3} }{4}(64cm^{2} )\\A_{triangle }=16\sqrt{3} cm^{2}$

The area of both triangles is

$A_{triangles}=2(16\sqrt{3}cm^{2} )=32\sqrt{3} cm ^{2}$

Now, the area of the whole figure is the sum of the area of triangles and rectangles

$A_{total}=480cm^{2} +32\sqrt{3} cm^{2} \approx 535.43 cm^{2}$

Therefore, the area of the total figure is around 535.43 square centimeters.

Hey there!

The correct graph is A

The slope, 2, is a positive slope, which means that the graph will go left to right going up, which rules out graph B.

The y-intercept is 1, which means it will intercept the y-axis at point (0, 1). That rules out graph C.

This means that graph A is correct.

Hope it helps and have a great day!
