Answer:

77cm²

Step-by-step explanation:

Okay, so first you have to find the area of all the shapes that make up the net, I'm going to start with the triangle:

So the height is 2 and the base is 5, so we plug this into our equation to get:

2 x 5 ÷ 2 = 5

There's 2 triangles so:

5 x 2 = 10

Then we start on the rectangles, we're going left to right:

6 x 3 = 18

5 x 5 = 25

4 x 6 = 24

Then we add that all up:

10 + 18 + 25 + 24 = 77

So the net of the triangular prism is 77cm²

hope this helps:)

. Two bicyclists, Sarah and Emily, depart from the same location. Sarah heads N55°E at an average speed of 6 km/hr. Emily heads
Liula [17]

Answer:

The distance between them after 30 minutes is 6.5 km.

Step-by-step explanation:

Speed = \frac{distance}{time}

Sarah's speed = 6 km/hr = 1.6667 m/s

Emily's speed = 10 km/hr = 2.7778 m/s

The measure of angle between their bearings = 105^{o}

After 30 minutes (1800 seconds);

distance = speed x time

Sarah would have covered a distance = 1.6667 x 1800

                               = 3000 m

                               = 3 km

Emily would have covered a distance = 2.7778 x 1800

                               = 5000 m

                               = 5 km

The distance between them, a, can be determined by applying the cosine rule;

a^{2} = b^{2} + c^{2} - 2bcCos A

   = 5000^{2} + 3000^{2} -2(5000 x 3000) Cos 105

   = 5000^{2} + 3000^{2} -2(5000 x 3000) x (-0.2588)

   = 2.5 x 10^{7} + 9 x 10^{6} + 7764000

   = 41764000

a = \sqrt{41764000}

  = 6462.5073

a = 6462.5 m

The distance between them after 30 minutes is 6.5 km.

Find the y-intercept of each exponential function and order the functions from least to greatest y-intercept.
kvv77 [185]

Answer:

Keep the exact order that is shown

Step-by-step explanation:

The first exponential already has a point at (1, -2) which means the y-intercept would be less than -2, which is the lowest among the three


The second has a y-int at -2

Third has y-int at 2
