jok3333 [9.3K]

Answer:

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°

PLS HELP 25 POINTS thanks uou​
maw [93]

Answer:

top: 2.6 units²

bottom: 2.83 units²

Step-by-step explanation:

so you need to know a couple of things

1) the inscribed polygons are made up of isoceles triangles (the top one has 6 and the bottom one has 8 triangles)

2) we know the length of each side of the isosceles triangles (given as r = 1 for all triangles)

3) we know that the entire circle is 360 degrees and therefore the angle of segment of the pie is 360° ÷ number of triangles in each circle

for the top, each segment has an angle of 360°÷6 = 60°

for the bottom, each segment has an angle of 360° ÷ 8 = 45°

4) We can find the area of a triangle if we know two sides and the angle between the two known sides using the following formula

Area = (1/2) x (Length 1) x (Length 2) x sin (angle between them)

In our case, we know that the length of each side is the same length 1 and the angle between them is either 60° (for top) and 45° (for bottom)

hence,

Area of each triangle = (1/2) x 1 x 1 x sin (angle)

= (1/2) sin (angle)

Area of each polygon= area of each triangle x number of triangles

= (1/2) sin (angle) x number of triangles.

For the top, each segment angle is 60° and there are 6 triangles.

Area of top polygon = (1/2) sin (60°) x 6 = 2.6 units²

For the bottom, each segment angle is 45° and there are 8 triangles.

Area of top polygon = (1/2) sin (45°) x 8 = 2.83 units²
