Write an equation for the line that passes through (4,-6) and (-7,-6). Is the line parallel or perpendicular to the y-axis?

alisha [4.7K]

Answer:

y = -6, perpendicular

Step-by-step explanation:

You can use the points to find the slope of the line:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{-6-(-6)}{-7-4} =\frac{-6+6}{-7-4}=\frac{0}{-11}=0$

Then, using point-slope form, choose one set of coordinates to use for y1 and x1:

$y-y_{1}=m(x-x_{1})$

$y-(-6)=0(x-4)$

$y+6=0$

$y=-6$

Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.

Which equation represents the volume of a cone with the same base and height as the cylinder below?

Firdavs [7]

Answer:

Volume of cone = (1/3) * Volume of cylinder

Step-by-step explanation:

Use the formulas

Volume of cone = (1/3)* π r^2 *h

Volume of cylinder = π r^2 *h

Therefore

Volume of cone = (1/3) * Volume of cylinder

3. If the sum of (3+6i) and (4+pi) is (7+81), then what is the value of p?

Aliun [14]

Answer:

p=2

Step-by-step explanation:

(3+6i) and (4+pi) is (7+8i)

3+4 = 7

6i+pi = 8i

Subtract 6i from each side

pi = 8i-6i

pi = 2i

That means p = 2
