Answer:
v = ± sqrt(6/5)
Step-by-step explanation:
v^2+2=8-4v^2
Add 4v^2 to each side
v^2+ 4v^2+2=8-4v^2+ 4v^2
5v^2 +2 = 8
Subtract 2 from each side
5v^2 +2-2 = 8-2
5 v^2 = 6
Divide each side by 5
5v^2 /5 = 6/5
v^2 = 6/5
Take the square root of each side
sqrt(v^2) = ± sqrt(6/5)
v = ± sqrt(6/5)
Answer:
f(d)=400(0.794)^d
Step-by-step explanation:
We have the expression

We can already simplify x because it's both on the numerator and denominator

Now we can simplify 425/25 = 17

Remember that

Then

The final result is
Answer:
-20
Step-by-step explanation:
32-12=20 so do it backwards. :D
