The formula a=v-u/t is used to find the acceleration for an object that increases its speed from u to v in a time t. If i = 4.5m/s (to 1d. p.), v = 10.2 m/s (to 1 d. p.) and t=3.6s (to 1d. p.), calculate the upper bound for the acceleration

Yvaries inversely as x. y =12 when x=5. find y when x=4

Which expression is equivalent to 64 - 9x^2?
