Answer:
I'm pretty sure that this is the answer 41 square root
Answer:
12
Step-by-step explanation:
BC would equal the same as EF, they are similar. All you would have to do is figure out the pre image (BC) of EF.
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>
