You can either find the roots of the quadratic formula using the quadratic formula two find the halfway point or you can use the formula t=-b/2a. Both of the two methods gives you the axis of symmetry (the t value for the vertex).
I will use the second method since I don't like using the quadratic formula.
t=-32/(2x-16)
t=1 second
After you find the t value for the axis of symmetry, you plug it into the formula of the graph to find the height.
h=-16+32+14
h=30 feet
3x+18

</h2>
Step-by-step explanation:
Expand the terms in the bracket and simplify
That's
Using the subtraction property subtract 10x from both sides of the equation
<u>Add 6 to both sides of the equation</u>
<u>Divide both sides by 8</u>
<u>Reduce the fraction with 2</u>
We have the final answer as

Answer:
0.015x
Step-by-step explanation:
The amounts earned at the different rates are ...
at 2%: 0.02x
at 3.5%: 0.035x
The difference in earnings is ...
0.035x -0.02x = 0.015x
