Answer:
The answer would be positive 6
Step-by-step explanation:
I know it is -6 because when you solve this you do...
-x = -6
Divide both sides by -6
-x/-6 = -6/-6
the answer would be 6
because a negative divided by a negative is a positive.
Hope this helps have a great day! :)
Answer:
slope of CE is 2/3
Step-by-step explanation:
used the slope formula: change in y-values / change in x-values
Answer:
(879,120)÷(56709072) ×(-659340)=-10221.274
Step-by-step explanation:
we use bedmas rules when it comes to long solving questions.
That is the combination of 10 over 3, which is calculated as the quotient of factorials:
n!/k!(n-k)!
where n = 10 and k = 3:
= 10!/3!(10 - 3)!
= 10!/3!*7!
= (10*9*8)/(3*2*1)
= 720/6
= 120
therefore there a re 120 possible different groups
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)\\\\](https://tex.z-dn.net/?f=%5Ctan%20%5E2%5Cleft%28x%5Cright%29%5Cleft%282%5Ccos%20%5E2%5Cleft%28x%5Cright%29%2B%5Csin%20%5E2%5Cleft%28x%5Cright%29-1%5Cright%29%5C%5C%5C%5C)
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)](https://tex.z-dn.net/?f=%3D%5Cleft%28-1%2B1-%5Ccos%20%5E2%5Cleft%28x%5Cright%29%2B2%5Ccos%20%5E2%5Cleft%28x%5Cright%29%5Cright%29%5Ctan%20%5E2%5Cleft%28x%5Cright%29)
![=\cos ^2\left(x\right)\tan ^2\left(x\right)](https://tex.z-dn.net/?f=%3D%5Ccos%20%5E2%5Cleft%28x%5Cright%29%5Ctan%20%5E2%5Cleft%28x%5Cright%29)
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)](https://tex.z-dn.net/?f=%3D%5Cleft%28%5Cfrac%7B%5Csin%20%5Cleft%28x%5Cright%29%7D%7B%5Ccos%20%5Cleft%28x%5Cright%29%7D%5Cright%29%5E2%5Ccos%20%5E2%5Cleft%28x%5Cright%29%5C%5C%3D%20%5Csin%20%5E2%5Cleft%28x%5Cright%29)
