Answer:

Undefined

Step-by-step explanation:

It's undefined since slope is based on the x coordinate, and since it doesn't change here there is none. It's also undefined because the line is vertical. Hope this helps :)

Answer:

$46.2^o$

Step-by-step explanation:

The correct question is

If b = 9 and c = 13, what is the measure of ∠A? (round to the nearest tenth of a degree)

The picture in the attached figure

we know that

In the right triangle ABC

$cos(A)=\frac{b}{c}$ ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(A)=\frac{9}{13}$

using a calculator

$A=cos^{-1}(\frac{9}{13})=46.2^o$

There are 11 students on the tennis team. The coach selects 3 of them to go to atennis clinic. In how many ways can he choose 3

Komok [63]

Answer:

165 ways

Step-by-step explanation:

Selection deals with combination

There are a total of 11 from which 3 are to be selected

11C3 = 11!/3!(11-3)!

= 11!/(3!x8!)

=(11x10x9x8!)/(3x2x8!)

=11x10x9/6

=11x5x3 = 165 ways
