Given the equation modeling Eva's height at time,t. To evaluate if she will reach height of 14 ft, we evaluate maximum height that she will reach.
At maximum height h'(t)=0
but
h(t)=-16t^2+20t+6
h'(t)=-32t+20=0
solving for t we get:
-32t=-20
t=20/32
t=5/8
thus the maximum height reached was:
h(5/8)=-16(5/8)^2+20(5/8)+6
h(5/8)=12.25 ft
Thus we conclude that she won't reach the height of 14 ft because her maximum height was 12.25 ft
To find the answer you need to find the square root of e^2 to get e so what you do to one side of the equation you do to the other side of the equation so find the square root of 0.36.
e=positive or negative 0.6
The net worth of the stock of Paul is $421.6 approximately.
<u>Solution:</u>
Given, two years ago, Paul bought $350 worth of stock in a cell phone company.
Since then the value of his stock has been increasing at an average rate of % per year.
We have to find how much is the stock worth now?
Now, stock worth after 1 year is given as:
So, now, stock worth after 2 years is given as:
Hence, the net worth of the stock is $421.6 approximately.
