What is the equation of the line, in point-slope form, that goes through (-2,-1) and is perpendicular to y=5x+3?
Lemur [1.5K]

The correct answer is B. y + 1 = -1/5 (x + 2)

I got B by putting the numbers in point-slope form which is y - y1 = m ( x - x1 ) so I got:     y + 1 = m ( x + 2 )

Then to find m(the slope) I knew if the slope was 5 it would be parallel to y=5x+3 so therefore -1/5 would be perpendicular to the line y=5x=3.

Hope that helps!!

Answer:

The radius of these cylinders is approximately 1 foot.

Step-by-step explanation:

According to this graph, the volume of the cylinder is directly proportional to its height, that is, radius remains constant. The expression of direct proportionality:

V \propto h

V = k\cdot h (1)

Where:

V - Volume of the cylinder, in cubic feet.

h - Height of the cylinder, in feet.

k - Proportionality constant, in square feet.

Besides, the proportionality constant is described by this expression:

k = \pi \cdot R^{2} (2)

Where R is the radius of the cylinder, in feet.

If we know that h = 9\,ft and V = 28.26\,ft^{2}, then the radius of the cylinder is:

k = \frac{V}{h}

k = 3.14

R = \sqrt{\frac{k}{\pi} }

R \approx 1\,ft

The radius of these cylinders is approximately 1 foot.
