P^-4q^3r^-7 over p^-2q^3p^-2 simplify

kondaur [170]

Answer:

$\large\boxed{r^{-7}=\dfrac{1}{r^7}}$

Step-by-step explanation:

$\dfrac{p^{-4}q^3r^{-7}}{p^{-2}q^3p^{-2}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=p^{-4-(-2)-(-2)}q^{3-3}r^{-7}\\\\=p^{-4+2+2}q^0r^{-7}\\\\=p^0q^0r^{-7}\\\\=r^{-7}\qquad\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=\dfrac{1}{r^7}$

What is the radius of a circle whose endpoints of a diameter are A(-4, 14) and B (2,8)

kupik [55]

Answer:

3√2

Step-by-step explanation:

The length of the diameter is given by the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((2 -(-4))² +(8 -14)²) = √(36 +36) = 6√2

The radius is half the diameter, so the radius of your circle is 3√2.

What is the area of a circle with a diameter of 23 centimeters? Use 3.14 for pi. Enter your answer, as a decimal, in the box.

Travka [436]

The equation for the area of a circle is A = PI x r^2

R = radius, which is half the diameter = 23/2 = 11.5

Area = 3.14 x 11.5^2

Area = 3.14 x 132.25

Area = 415.265 square cm.

Tanner needs repairs for his truck. He can take it to Gary’s Garage for a service charge of $40 plus $30 per hour. He can also t

oksano4ka [1.4K]

Answer:

Step-by-step explanation:

G=30t+40, C=20t+60, C=G

30t+40=20t+60, subtract 40 from each side

30t=20t+20, subtract 20t from each side

10t=20, divide each side by 10

t=2

So both garages charge the same fot two hours of work.
