COPY-<br> Evaluate each expression if a = 4, b = 6, and c = 2<br> -> 3a +6²c<br> What is

Klio2033 [76]

Step-by-step explanation:

a=4 so 3a becomes 3x4.

3x4=12

12+6c^2

C=2 so 6c^2 becomes (6x2)^2

6x2=12 and 12x12 because of the exponent.

12x12=144

12+144=156

If it's wrong, i'm sorry

Pls help i don’t know how to do this

algol [13]

Answer: $\displaystyle\\\frac{2\pi }{3},\ \frac{5\pi }{3} .$

Step-by-step explanation:

$\displaystyle\\tan\theta=-\sqrt{3}\ \ \ \ 0\leq \theta\leq 2\pi \\\theta =\frac{2\pi }{3}+\pi N\ \ \ (N=0,\ 1,\ 2,\ 3\ ...)\\ N=0\\\theta=\frac{2\pi }{3} +\pi *0\\\theta=\frac{2\pi }{3}\ \ \ \ ( 0\leq \theta\leq 2\pi)\\ N=1\\\theta=\frac{2\pi }{3}+\pi *1 \\\theta=\frac{2\pi }{3} +\pi \\\theta=\frac{2\pi +3\pi }{3} \\\theta=\frac{5\pi }{3} \ \ \ ( 0\leq \theta\leq 2\pi)\\$

$N=2\\\theta=\frac{2\pi }{3}+2\pi \\ \theta=\frac{2\pi +3*2\pi }{3}\\ \theta=\frac{2\pi +6\pi }{3} \\\theta=\frac{8\pi }{3} \\\theta=2\frac{2}{3} \pi \ \ \ \ (\notin0\leq \theta\leq 2\pi).\\$

Here are the prices for 8 different MP3 players. Find the standard deviation.

Elis [28]

The mean is 250.875.

Using this information, I can put the following into a calculator:
√(((250.875-195)²+(250.875-358)²+(250.875-201)²+(250.875-276)²+
(250.875-161)²+(250.875-301)²+(250.875-387)²+(250.875-128)²)÷8)

Which equals:
87.9878

This is the standard deviation of the MP3 players.

A tour bus starts from Memphis and heads to Miami at 50 mph. Three hours later a truck pursues the bus at a speed of 65 mph. How

Nina [5.8K]

Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)
