Answer:

y = 2x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (- 2, 0 ) into the partial equation

0 = - 4 + c ⇒ c = 0 + 4 = 4

y = 2x + 4 ← equation of line

A right cone has a surface area of 440 square inches and a radius of 7 inches. Find its slant height.

EastWind [94]

Answer:

Surface Area of right cone

= $\pi r(r+\sqrt{h^2 + r^2}$

$440 = \pi *7*(7+\sqrt{h^2+7^2})\\\\440 = 7\pi (7 + \sqrt{h^2+7^2})\\\\\frac{440}{7\pi } = 7 + \sqrt{h^2+49}\\\\\frac{440}{7\pi } - 7 = \sqrt{h^2+49}\\\\\frac{440-49\pi}{7\pi} =\sqrt{h^2+49}\\\\$

$\frac{286.062}{21.99} =\sqrt{h^2+49}\\\\13.0087= \sqrt{h^2+49}\\\\(13.0087)^2 = (\sqrt{h^2+49})^2\\\\169.227 = h^2 +49\\\\169.227 - 49 =h^2\\\\120.227 = h^2\\\\h = \sqrt{120.227} = 10.96in$

A line is shown in the graph below.

Kay [80]

Answer:

-3/2

Step-by-step explanation:

One can read off the slope of the given line directly from the graph. As x increases by 3, y increases by 2. Thus, the slope of the given line is

m = rise / run = 2 / 3

Any line perpendicular to this given line has a slope which is the negative reciprocal of the slope previously found:

-1 3

Slope of perpendicular line = ------------ = - -----

2/3 2

This matches the first of the given possible answer choices.
