The number 6 could replace the gap :)
The given function is

According to this function, the starting height of the rocket is 20 feet because that's the initial condition of the problem stated by the independent term.
Additionally, we find the maximum height by calculating the vertex of the function V(h,k).

Where a = -16 and b = 300.

Then, we find k by evaluating the function

Hence, the maximum height is 1426.25 feet.
At last, to know the time need to hit the ground, we just use h=9.375 and we multiply it by 2

Hence, the rocket hits the ground after 18.75 seconds.
Answer:
B
Step-by-step explanation:
The equation for B equals a negative answer
Answer:
360 minutes
Step-by-step explanation:
(1.5 h/wk)·(4 wk)·(60 min/h) = 1.5·4·60 min = 360 min
Multiply reading time per week by the number of weeks to get reading time. Multiply the number of hours by the number of minutes in an hour to get minutes.
2)
The area of the whole polygon can be found by adding the area of the top square and the bottom rectangle.
Area of square = 1² = 1
Area of rectangle = 3 × 4 = 12
Area of whole polygon = 1 + 12 = 13 inches²
Hope this helps :)
