Excited by the recent warm weather Jill and Kelly are doing spring cleaning at their apartment. Jill takes an exponen- tially di

stributed amount of time with mean 30 minutes to clean the kitchen. Kelly takes an exponentially distributed amount of time with mean 40 minutes to clean the bathroom. The first one to complete their task will go outside and start raking leaves, a task that takes an exponentially distributed amount of time with a mean of one hour. When the second person is done inside, they will help the other and raking will be done at rate 2. (Of course the other person may already be done raking in which case the chores are done.) What is the expected time until the chores are all done?

A ball is launched out of a cannon that is 24 feet off the ground. The height of the ball after "t" seconds is represented by
Olegator [25]

Given:

The height of ball is represented by the below function:

h(t)=-16t^2+20t+24

To find:

The number of seconds it will take to reach the ground.

Solution:

We have,

h(t)=-16t^2+20t+24

At ground level, the height of ball is 0, i.e., h(t)=0.

-16t^2+20t+24=0

Taking out greatest common factor.

-4(4t^2-5t-6)=0

4t^2-5t-6=0

Splitting the middle term, we get

4t^2-8t+3t-6=0

4t(t-2)+3(t-2)=0

(t-2)(4t+3)=0

Using zero product property, we get

(t-2)=0 and (4t+3)=0

t=2 and t=-\dfrac{3}{4}

Time cannot be negative, so t=2.

Therefore, the ball will reach the ground after 2 seconds.
