Answer:

  y = 1/2x -2

Step-by-step explanation:

The given equation is in slope-intercept form, so you recognize its slope is -2. The perpendicular line will have a slope that is the opposite reciprocal of that, so is -1/-2 = 1/2.

The y-intercept can be found from ...

  b = y -mx . . . . . for line of slope m through point (x, y)

  b = -1 -(1/2)(2) = -1 -1 = -2

Then the slope-intercept equation of the perpendicular line is ...

  y = 1/2x -2

Answer:

240 \leq 12.5p + 65

14 \leq\\ p

Step-by-step explanation:

I'll explain the equation in different parts

12.5p - Since the number of times he visits is unknown, it has to be a variable. With each visit, however, he earns 12.5 points.

65 - This is a set value that remains constant

240 \leq\\ - Since he needs AT LEAST 240 points, he needs 240 points or more to get his free ticket

As for solving the equation just use properties of equality

240 \leq 12.5p + 65

175 \leq 12.5p

14 \leq\\ p

What is the volume of a cylinder with a height of 3 feet and a radius of 4 feet use 3.14 for pi
Vlad1618 [11]

Answer:

\large\boxed{V\approx150.72\ ft^3}

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

We have the height H = 3ft and the radius r = 4ft. Substitute:

V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3

\pi\approx3.14

V\approx48(3.14)=150.72\ ft^3
