Step-by-step explanation:
Given that the equation for the firecracker is h = − 5 t^2 + 30 t + 20
It is impossible to solve this question unless the height (h) in meters is supplied. If the height was supplied, we could set up the quadratic equation and solve it yielding two values for the time. The values of t obtained is the time in seconds required for the firecracker to reach the given height h.
You can apply these tips and solve the question seamlessly.
The missing number is 225

Answer:
you will put 2.2% interest which represents your C D, by then they will add 750+2.2
Answer:
A ≈ 81.487 in²
Step-by-step explanation:
You know that circumference is C = 2πr, where r is the radius.
So,
C = 2πr
32 = 2(3.14)r
r ≈ 5.093 in
We also know that the formula for the area of a circle is A = πr², so:
A = πr²
A = (3.14)(5.093)²
A ≈ 81.487 in²
