Write the equation of the line that passes through the points (−7,5) and (-7,-8).

Viefleur [7K]

Answer:

x = -7

Step-by-step explanation:

First we find the slope using

m = ( y2-y1)/(x2-x1)

= ( -8 - 5)/( -7 - -7)

= (-8-5)/(-7+7)

= -13/0

This means the slope is undefined and the line is vertical

Vertical lines are in the form

x= constant and the constant is the x value of the points

x = -7

Which equation can be used to find the surface area of the cylinder?

miss Akunina [59]

Answer:

The fourth one

Step-by-step explanation:

Surface area of a cylinder: $SA=2\pi rh+2\pi r^2$

where r = radius and h = height

We have a given height of 14cm and a given diameter of 6cm

We need the radius, not the diameter

To convert diameter to radius we simply divide by 2

6 / 2 = 3

so R = 3

We now plug in the given values into the formula

$SA=2\pi (3)(14)+2\pi (3)^2$

This equation matches with answer choice D
