Find the equation of the line that is perpendicular to the line 4x+2y=1 and passes through the point (-4,3)

First find the slope of the given line:

4x +2y = 1

Subtract 4x from each side:

2y = -4x + 1

Divide both sides by 2:

y = -2x +1/2

The slope is -2.

Now use the slope to find the y-intercept. Because  the line is perpendicular, you need to use the negative inverse of the slope.

The negative inverse of -2 is 1/2

Now using the point-slope form y - y1 = m(x-x1)

Use the inverse slope for m, and the given point(-4,3) to get:

y - 3 = 1/2(x+4)

Simplify:

y - 3 = x/2 +2

Add 3 to each side:

y = x/2 + 5

Reorder the terms to get y = 1/2x +5

The answer is D.

What is the volume of a come that has a height of 40 millimeters and a diameter of 25 millimeters? Use 3.14 for pi.
Fantom [35]

Answer:

6541.7 mm³ (nearest tenth)

Step-by-step explanation:

\boxed{volume \: of \: cone =  \frac{1}{3}\pi {r}^{2}h  }

Given that the height is 40mm, h= 40mm.

Diameter= 2(radius)

Radius of cone

= 25 ÷2

= 12.5mm

Volume of cone

=  \frac{1}{3} (3.14)(12.5)^{2} (40)

= 6541.7 mm³ (nearest tenth)
