What is the equation of the line that passes through (0, -2) and has a slope of O?
Dmitriy789 [7]

Answer:

The equation of the line that passes through (0, -2) and has a slope of 0 is \mathbf{y=-2}

Step-by-step explanation:

We need to find the equation of the line that passes through (0, -2) and has a slope of 0?

The equation of line can be expressed in slope-intercept form y=mx+b where

  • m is slope
  • b is y-intercept

We need to find slope and y-intercept for the equation.

We are given slope = 0 so, m = 0

Now, y-intercept can be found using slope m=0 and point (0,-2)

y=mx+b\\-2=0(0)+b\\-2=b\\or\\b=-2

So, we get y-intercept: b = -2

Now, the equation of the line having slope m=0 and y-intercept b=-2 is:

y=mx+b\\y=0(x)-2\\y=-2

So, the equation of the line that passes through (0, -2) and has a slope of 0 is \mathbf{y=-2}

If the height of the cone, h, is 15 centimeters and the radius of the base, r, is 5 centimeters, what is the volume of the conte
Deffense [45]

Answer:

Step-by-step explanation:

The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Where

h represents the height of the cone

r represents the radius of the cone

π is a constant whose value is 3.14

From the information given

Radius = 5 centimeters

Height = 15 centimeters

Therefore,

Volume of cone = 1/3 × 3.14 × 5² × 15 = 392.5 cubic centimeters
