Find the midpoint of the segment with the given endpoints. (9,9) and (6,8)

mars1129 [50]

Answer:

The mid-point is (7.5, 8.5).

Step-by-step explanation:

We are given two points (9,9) and (6,8) as the endpoints for a line segment and we are to find the midpoint of this segment.

We know that the formula for finding the mid point is:

Mid point = $(\frac {x_1 + x_1 }{ 2 } ,\frac { y_1 + y_2} {2} )$

So substituting the given values of the coordinates of the endpoints in the above formula to get:

$= (\frac {9 + 6}{2} , \frac {9 + 8}{2} )$

$= (\frac {15}{2} , \frac {17} {2} )$

$=(7.5, 8.5)$

Therefore, the mid-point is (7.5, 8.5).

A ramp 17 1/2 feet in length rises to a loading platform that is 3 1/2 feet off the ground. Find the angle that the ramp makes w

faltersainse [42]

Answer:

The angle that the ramp makes with the ground is 11.54°

Step-by-step explanation:

From the image attached, we can see that the length of 17 1/2 ft corresponds to the hypotenuse in a right triangle, the length of 3 1/2 ft corresponds to the opposite side.

We can use the fact that the sin(θ) = $\frac{Opposite}{Hypotenuse}$ to find the angle that the ramp makes with the ground.

$sin(\theta)=\frac{3.5}{17.5}$

The angle is equal to

$\theta = sin^{-1}(\frac{3.5}{17.5} )\\\theta = 11.54\°$
