A car tire has a radius of 10.4 inches. What distance will the tire travel after 20 rotations?
Ganezh [65]

Answer:

Distance traveled after 20 rotations = 1306.24 inches

Step-by-step explanation:

r = 10.4 inches

Distance traveled in one rotation = Circumference of the car tire

Circumference of the car tire = 2πr

                                                 = 2 * 3.14 * 10.4

                                                = 65.312 inches

Distance traveled after 20 rotations = 65.312 * 20

                                                            = 1306.24 inches

mario62 [17]

Answer:

4/15

Step-by-step explanation:

Make both fractions have equal denominators:

<u>2</u> x3      ----->   6/15

5 x3

                                            6/15 + 5/15 = 11/15 --->  15/15 - 11/15 = 4/15

<u>1</u> x5      ------>  5/15

Which of the following represents the vertical asymptotes of the function
Thepotemich [5.8K]
The expression in the denominator is \displaystyle{ x^2-2x-8.

We can use this expression by completing the square, and the difference of squares as follows:

\displaystyle{ x^2-2x-8=(x^2-2x+1)-9=(x-1)^2-3^2

=(x-1-3)(x-1+3)=(x-4)(x+2).

So, the zeros of the polynomial \displaystyle{ P(x)=x^2-2x-8 are x=4 and x=-2.


Thus, the asymptotes are the lines x=-2, and x=4.
