y = 12 is a line in which every point has a y-coordinate of 12 no matter what the x-coordinate is. That means that y = 12 is a horizontal line. The equation of line y = 12 can be written as y = 0x + 12 clearly showing m = 0 (slope is zero) and the y-intercept is 12. A line parallel to line y = 12 has the same slope, so its slope is also zero.

A line perpendicular to y = 12 is a vertical line. For a vertical line, the slope is undefined because it involves division by zero which is undefined in math.

A ball is thrown from an initial height of 3 feet with an initial upward velocity of 30/fts . The ball's height h (in feet) afte

Vlad [161]

At 16 feet we have
16 = 3 + 30t - 16t^2

16t^2 - 30t + 13 = 0

t = [- -30 +/- sqrt(30^2 - 4*16*13) ] / 32

t = 1.20 , 0.68 seconds answer ( correct to the nearest hundredth)

Answer:

Length of the rope = 15.6 ft.

Step-by-step explanation:

Given:

Height of the pole from the ground = 12 ft

Adjacent distance from the pole = 10 ft

We have to find the length of the rope attached by Scott to secure the pole.
