2.813123501 ft

solution:

h/80=cos 87
h=80*cos87
x=7-(80*cos 87)
x=2.813123

Match the coordinates with the points on the coordinate plane
Gnesinka [82]

Answer:

Step-by-step explanation:

(-2\frac{1}{2},3\frac{1}{2})

Since, x-coordinate is negative and y-coordinate is positive, point will lie in the 2nd quadrant.

Answer is point P.

(-3, 6)

Point L represents the given coordinates.

(-4\frac{1}{2},2)

Point P represents the given coordinates.

(2\frac{1}{2},2\frac{1}{2})

Since, x and y coordinates are positive, point will lie in the 1st quadrant.

Point Q represents the given coordinates.

(-1\frac{1}{2},-3\frac{1}{2})

Since, both x and y coordinates are negative, point will lie in the 3rd coordinate.

Point R represents the given coordinates.

A cyclist accelerates at a rate of 7.0 m/s2. how long will it take the cyclist to reach a speed of 18 m/s?
mart [117]
At constant acceleration  the equation  is

v = u + at     where u = initial speed,  a = acceleration. t = time and v = final speed

So here we have  18 = 0 + 7t

t = 18/7  = 2.6 seconds ( to nearest tenth)
