Step-by-step explanation:

$p(x) = {x}^{3} - 4x - 5 \\ p( - 2) = {( - 2)}^{3} - 4( - 2) - 5 \\ = - 8 + 8 - 5 \\ = - 5$

Answer:

The answer would be -5.

Step-by-step explanation:

First I plugged in negative 2 for every x in the equation, which gives me:

p(-2) = (-2)³ - (4(-2)) - 5.

We solve for the exponents first, which gives us a total of -8 because we are multiplying -2 by itself 3 times. Then we multiply 4 and -2, which gives us negstive 8. However, the first -8 and the second -8 cancel out because the equation has a - sign in between the two, leaving us with only -5. -5 is the answer.

Ksenya-84 [330]

Answer:

21 is 20% of 105

Step-by-step explanation:

20% * x = 21

20/100 * x = 21

x = 21 * 100/20

x = 105

If you are using a calculator, simply enter 21×100÷20, which will give you the answer.

Newton’s law of universal gravitation, F=Gm1m2/r²,measures the force of gravity between two masses m1 and m2,where r is the dist

Pavel [41]

Answer:

$G=\frac{Fr^2}{m_1m_2}$

Step-by-step explanation:

Since our equation is $F=\frac{Gm_1m_2}{r^2}$ and we want to solve for G, first we divide both sides by the product $m_1m_2$ , which gives:

$\frac{F}{m_1m_2}=\frac{Gm_1m_2}{m_1m_2r^2}=\frac{G}{r^2}$

So we are left with:

$\frac{F}{m_1m_2}=\frac{G}{r^2}$

Now we multiply both sides by $r^2$ , which gives:

$\frac{Fr^2}{m_1m_2}=\frac{Gr^2}{r^2}=G$

Which gives us our final formula:

$G=\frac{Fr^2}{m_1m_2}$
