The case is the case for which the solution to an equation is obtained directly.

The answer is a base case. This is a part of an algorithm or recursive definition that is not clear in terms of itself. The basis in mathematical induction, displaying that a statement grasps when n is equal to the lowest value that n is assumed in the question.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
