Answer:

\huge\boxed{x=14.2}

Step-by-step explanation:

Use a cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have:

adjacent=12\\hupotenuse=x\\measure\ of\ angle=32^o

Look at the picture or use the calculator.

\cos32^o=0.8480

Substitute:

0.848=\dfrac{12}{x}\\\\\dfrac{0.848}{1}=\dfrac{12}{x}

cross multiple

0.848x=12

divide both sides by 0.848

x=\dfrac{12}{0.848}\\\\x=14.2

mixer [17]

Answer:

d = 56x + 412

Step-by-step explanation:

To find the total number of miles traveled on Monday and Tuesday, use a linear equation to write the function.

y = mx+b where m is the speed or rate of change and b is the starting point.

The starting point on Tuesday is 412 miles. This is b.

The number of miles traveled on Tuesday is found by calculating 56 miles times the number of hours traveled.  This is the slope or m.

So the equation is d = 56h + 412.

Answer: It represents the area of the two circular sides ("lids")

Explanation:

Imagine you made a cylinder out of 3 pieces of paper. The cylinder can be decomposed into two circular shapes (radius r) and one rectangular piece with two side lengths: one is "h", the other has to be long enough to go around each of the disks, so it has to be 2*pi*r long.

So the term 2*pi*r*h is the area of the rectangular piece and pi*r^2 is the area of each of the "lids" Since there are two of those, the term 2*pi*r^2 represents the area of the bottom and top lids.
