14. A satellite orbits 22, 300 miles above the equator. It completes one revolution in 24 hours. Assume that the radius of the E
quester [9]

Answer:

Displacement = 0 mi

Distance = 164,996.45 mi

Step-by-step explanation:

In this case, the displacement will be zero because the satellite goes back to its starting point after one day. If there is no distance traveled between the starting point and the ending point, then the Displacement will be zero.

When it comes to the distance, we will need to calculate the perimeter of the circle the satellite describes when making one whole turn around the earth.

The perimeter of a circle is given by the equation:

p=2\pi r

so we need to start by finding what the radius of the circle is. This radius if found by adding the radius of the earth and the distance above the equation the satellite is located at, so we get that:

r=r_{earth}+h

where h is the height of the satellite, so the radius of the circle is:

r=22,300mi + 3,960 mi

so

r=26,260 mi

so now we can use the perimeter equation to get:

p=2\pi r

p=2\pi (26,260)

So the distance traveled by the satellite in one day will be:

P=164,996.45 mi.

Help me iwht this one please
EleoNora [17]

Answer:

x = -15

Step-by-step explanation:

In fractional equations we cross multiply the expressions:

In cross multiplying the denominator of the first fraction is multiplied with the numerator of the second fraction and vice versa:

-2x = 30 divide both sides by -2

x = -15

A team of ranger marked 24 squirrels in a park. Later, a class counted 480 squirrels, 16 of which were marked. To the nearest wh
Hitman42 [59]

Answer: 720

Step-by-step explanation:

480 : 16 marked

480-16 = 464

They saw 464 unmarked squirrels and 16 marked squirrels

464/16 = 29

They saw 29 unmarked squirrels for every 1 makes squirrel

29 * 24 = 696

They would have seen 696 unmarked squirrels for the 24 marked squirrels.

696 + 24 = 720

Darren runs 1/4 mile in 2.5 minutes.how long it will take him to run a full mile
Goshia [24]
Since he can run 1/4 of a mile in 2.5 minutes, he will run a full mile in 4*2.5 =10 minutes, assuming he runs at a steady speed.

which of the following explains how triangle BEI could be proven similar to triangle CEH using the AA similarity postulate?
Viefleur [7K]

Answer:

∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then translate point C to point B to confirm∠IBE ≅ HCE.
