Find the balance of a savings account at the end of years if the interest earned each year is . %. The principal is $. what is it please?

You can use the time value of money formula.

FV = PV(1 + r)^n

FV = future value

PV = present value

r = interest rate = percentage/100

n = number of compounding periods

FV = 500*(1 + 0.075)^10 = $ 1030.52

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
