Answer:

The answer is $d(t)=3,906,000$ miles.

Step-by-step explanation:

To solve this is pretty easy,

We know that the equation is $d(t)=186000t$ , and since we have to find the distance in 21 seconds, you just have to substitute the variable.

$t=time\\d(t)=186000(t)\\d(21)=186000(21)\\d(21)=3,906,000$

There are about 10^24 stars in the universe. Each galaxy has approximately the same number of stars as the Milky Way Galaxy. Abo

maks197457 [2]

Answer:

$10^{13}$ galaxies.

Step-by-step explanation:

There are about $10^{24}$ stars in the universe.

The Milky Way galaxy $10 * 10^{10}$ stars.

All we need to do to find the number of galaxies is to divide the total number of stars in the universe by the number of stars in the Milky Way:

Number of galaxies = (Number of stars in the universe) / (Number of stars in the Milky Way)

Number of galaxies = $\frac{10^{24}}{10 * 10^{10}}$

N = $\frac{10^{24}}{10^{11}}$

N = $10^{24 - 11} = 10^{13}$

The number of galaxies in the universe is approximately $10^{13}$ .

Sloane kicked a soccer ball at a speed of 56 feet per second. If the ball never leaves the ground, then it can be represented by

aksik [14]

Answer:

Third option: $t=3.5\ seconds$

Step-by-step explanation:

Given the function:

$H(t)=-16t^2 +56t$

Since the ball never leaves the ground, you need to substitute $H(t)= 0$ in the function in order to determine the time the soccer ball traveled:

$0=-16t^2 +56t$

Factorizing, you get:

$0=-8t(2t-7)$

Then:

$0=-8t\\\\t=0\ seconds\\\\\\\\0=2t-7\\\\7=2t\\\\t=3.5\ seconds$

Therefore the time the ball traveled was:

$t=3.5\ seconds$
