Michelle throws a frisbee into the air. The height of the frisbee at a given time can be modeled by the equation h(t)= -2t

(a) The ball will hit the ground after 3 seconds

(b) The maximum height is 6.125

Step-by-step explanation:

Given

Solving (a): When the frisbee will hit the ground?

To do this, we set h(t) to 0

So, we have:

Expand

Factorize

Factor out t - 3

Split:

Solve for t in both equations

Time can't be negative; So:

Solving (b): How height the frisbee will go?

First, we calculate time to reach the maximum height

Where:

By comparison:

So:

So, the maximum height is:

answer: rolling a number cube and flipping a coin.

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
