Suppose h(t) = -4t^2+ 11t + 3 is the height of a diver above the water (in
Bingel [31]
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds

Sarah pays a 20% deposit for a new TV and then an extra $96. What’s the total cost?
mixer [17]

A deposit (in this case) is a portion of the TV paid in advance - 20% of the total cost. That means that the 96$ makes up the remaining 80% of the total cost, which I'll represent as <em>x</em>. From here, we can set up an equation to find the total cost x, since we have a relation to form it on - <em>the fact that 80% of x is equal to 96$.</em>

0.8x = 96

\frac{0.8x}{0.8} = \frac{96}{0.8}

x = 120  

The total cost of the TV is 120 dollars.
