<h3>What is Quadratic Equation?</h3>
A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .
Given:
y= -16x²+33x+45
If the height is 30 feet.
30= -16x²+33x+45
-16x²+33x+45-30=0
-16x²+33x+15=0
16x²-33x-15=0
Solving the quadratic equation
x=-b±√b²-4ac/ 2a
x= 33 ± √2049/32
x= (33+ √2049)/32 and x=33-√2049/32
x=2.44 and -0.3833

Ryan already paid 3000 so we can subtract that from the total which gives us 4500 and now we divide 4500 by 36 which equals 125 so every month Ryan must pay $125 for 36 months to pay off the car.
Answer:
I believe the answer is $1.52. hope this helps

0.3 = 3/8 (equal to eachother)
Reason: (<u>3</u><u>/</u><u>8</u><u> </u><u>=</u><u> </u><u>0.375</u><u>)</u>
<u>So</u><u>,</u><u> </u><u>0</u><u>.</u><u>3</u><u> </u><u>is</u><u> </u><u>equal</u><u> </u><u>to</u><u> </u><u>eachother</u><u>. </u>
<u>0</u><u>.</u><u>3</u><u>=</u><u>0</u><u>.</u><u>3</u>
