For
, we have
and so
which is, again, only valid for
.
A
explanation:
2x+10=-6-30
8x+40=0
x=-5
The measure of the largest angle is 74°
i think that you are multiplying them so the answer is 3553.5
and if your adding it would be 122.1
For the answer to the question above, we will use this formula to solve this problem
<span>d = kv^2 </span>
<span>plugging in, </span>
<span>4.2 = k*10^2 </span>
<span>k = 0.042 </span>
<span>d = 0.042v^2 </span>
<span>the revoised equation will be </span>
<span>d = 0.9*0.042v^2 , i.e. </span>
<span>d = 0.0378v^2
I hope my answer helped you</span>
