Answer:  \bold{b)\quad \dfrac{\pi}{2}+n\pi,\ \dfrac{\pi}{4}+2n\pi}

<u>Step-by-step explanation:</u>

cos x tan x - cos x = 0

cos x (tan x - 1) = 0

cos x = 0          tan x - 1 = 0

x=\dfrac{\pi}{2},\ \dfrac{3\pi}{2}         tan x = 1

                         x=\dfrac{\pi}{4},\ \dfrac{5\pi}{4}

Someone please help!!

I think the correct answer here would be 1.8 units because this is a proportional triangle. Since we know the larger height is 5, and the smaller height is 1, we know that if we divide 9 by 5 (to create the same proportion) we will find that x=1.8.

A line contains (34,12) and (32,48) what is the slope of the line in simplified form? HELP ASAPl
Tcecarenko [31]

Answer:

m=-18

Step-by-step explanation:

1. The line contains the points (34,12) and (32,48). Then, you need to use the slope formula, which is:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

2. When you substitute values into the formula, you obtain:

y_{2}=48\\y_{1}=12\\x_{2}=32\\x_{1}=34

m=\frac{48-12}{32-34}\\m=\frac{36}{-2}\\m=-18
