Answer:

y=7x-47

Step-by-step explanation:

$(8, 9) = (x_1,y_1) \\ m = 7 \\ y - y_1 = m(x - x _1) \\ y - 9 = 7(x - 8)$

$y - 9 = 7x - 56 \\ y = 7x - 56 + 9 \\ y = 7x - 47$

The wheels of a monster truck are 66 inches tall. Find the distance the monster truck travels when the tires make one 360-degree

LuckyWell [14K]

Answer:

<u>207.35 inches</u>

Step-by-step explanation:

The wheel is in the shape of circle. The height, here, basically gives the diameter.

So,

Diameter = 66 in

Radius is half of diameter, so radius is:

66/2 = 33 inches

r = 33

Now, the distance truck travels when 1 rotation is made is the length of the perimeter of the circular wheel, or the circumference.

The formula is:

$C=2\pi r$

Where C is circumference

r is the radius

Substituting, we get the answer as:

$C=2\pi r\\C=2\pi (33)\\C=66\pi\\C=207.35$

The distance covered is about <u>207.35 inches</u>
