Answer:r=v^2/A
Step-by-step explanation: To solve for r means you have to isolate r on one side and put all the other terms on the other. To get r out from under the fraction, multiply both sides by r. This leaves:
A*r=v^2 so to isolate r, divide by A and get:
r=v^2/A.
I think it is 5.4 but I'm not really sure
Answer: The next three terms are 
Step-by-step explanation:
Since we have given that

After analyzing the above pattern, we get that
In numerator , numbers are run in consecutive manner.
In denominator, number is added to 3 to get the next term.
So, the general form would be 
So, the next three terms would be

Hence, the next three terms are

Answer:
7959.83
Step-by-step explanation:
A = P ( 1+r/n)^ nt
Where A is the amount in the account
P is the principal
r is the rate
n is the number of compoundings per year
t is the years
A =3000 ( 1+.10/2)^ 2*10
A =3000 ( 1+.05)^ 20
=7959.83
