question 20

40 gallons, 12 concentrate, 28 water

this is a fraction of 12/28

simplification: (12) divided by 12 / (28) divided by 12

1/2

1 part concentrate 2 parts water per each of the 40 total gallons.

so color in 33% for concentrate and 66% water

I am totally not wrong :D:D:D:D

If you know trig please help! Will give brainliest!

Answer:

sin^2α

Step-by-step explanation:

I will just pose x instead of alpha here to make things simpler

$\tan ^2\left(x\right)\left(2\cos ^2\left(x\right)+\sin ^2\left(x\right)-1\right)\\\\$

we know that sin^2x = 1 - cos^2x so...

$=\left(-1+1-\cos ^2\left(x\right)+2\cos ^2\left(x\right)\right)\tan ^2\left(x\right)$

$=\cos ^2\left(x\right)\tan ^2\left(x\right)$

we can rewrite using trigonometric identities (tan = sin/cos)...

$=\left(\frac{\sin \left(x\right)}{\cos \left(x\right)}\right)^2\cos ^2\left(x\right)\\= \sin ^2\left(x\right)$
