The x-intercept is the point where a line crosses the x-axis. So the x-intercepts for the 3 lines shown in the image provided are (-5,0), (-1,0), and (3, 0). Notice that all x-intercepts have a y-coordinate of zero.

Find the radius of a circle with a circumference of 30 units. Round your answer to the nearest tenth (1 decimal place).

Vlad [161]

Answer:

The radius would be 4.8

Step-by-step explanation:

The circumerfence of a circle can be found use the equation C=2 $\pi$ r. So since we are given the circumerce we need to rearrange the eqaution to it looks like $\frac{30}{2\pi }$ =r. when we do this out we find that the radius equals 4.8.

A ball is dropped from a height of 192 inches onto a level floor. After the third bounce it is still 3 inches off the ground. Pr

ANEK [815]

Answer: The required fraction = $\dfrac18$

Step-by-step explanation:

Let the required fraction = $\dfrac{p}{q}$

Given: Initial height = 192 inches

Height of ball after second bounce = $\dfrac{p}{q}\times192$

Height of ball after third bounce = $\dfrac{p}{q}\times\dfrac{p}{q}\times192=192\dfrac{p^2}{q^2}$

After the third bounce it is 3 inches off the ground.

So,

$(\dfrac{p}{q})^2192=3\\\\\\(\dfrac{p}{q})^2=\dfrac{3}{192}\\\\(\dfrac{p}{q})^2=\dfrac{1}{64}\\\\(\dfrac{p}{q})^2=(\dfrac{1}{8})^2\\\\ \dfrac{p}{q}=\dfrac{1}{8}$
