Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x
I think it’s 67 but I’m not sure
Answer:
slope is -1/2 and y- intercept is 1/3
Step-by-step explanation:
use y=mx+b
m=slope
b= y-intercept
rearrange your equation
y=1/3-1/2x
y=-1/2x+1/3
Answer:
here if im wrong my bad bro
Step-by-step explanation:

Answer:
Step-by-step explanation:make equations on : (x)+(x+5)(2x)=100
Then solve: 4x+5=100
X=23
Plug in her equation: 23+5= 28
So she is 28 years old
