Find the midpoint of the segment joining X(5,6) and Y(9,2).

makkiz [27]

Answer:

(7,4)

Step-by-step explanation:

The midpoint formula is:

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

Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:

$M=(\frac{5+9}{2},\frac{6+2}{2})$

Add:

$M=(\frac{14}{2},\frac{8}{2})$

Divide by 2:

$M=(7,4)$

So, our midpoint is (7,4).

And we're done!

A road has a 10% grade, meaning increasing 1 unit of rise to every 10 units of run.

fenix001 [56]

The grade is the ratio of rise to run, i.e. the slope aka the tangent.

$\tan \theta = \dfrac{1}{10}$

$\theta = \arctan 0.1 \approx 5.711^\circ$

Answer: (a) 6 degrees

For part b, the road is the hypotenuse c of a right triangle whose tangent of the small angle is 1/10. The height h or rise is the side opposite the small angle.

$\sin\theta = \dfrac h c$
