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)...

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

ivolga24 [154]

Since there is a total of 10 balls, then the fraction would be 3/10 , the decimal form would be 0.3, and the word form could be put in many ways. one way would be to say, "out of the total 10 sport balls,3 of them are kickballs."
