The question isn’t clear, can you write it better so I can understand?
You have to do the math right to get this right. so just add then multiply add them the subtract
Answer: The polynomial that describes the projectile's height is:
P(t) = - 16t*2 + 300t
For t = 1 second we have:
P(1) = - 16*1^2 + 300*1
P(1) = 284 ft
The height of the projectile after 1 second is 284 feet.

Answer:
113.12 cubic inches
Step-by-step explanation:
Volume of icecream cone
= Volume of cone + Volume of hemisphere
= 1/3× π × r^2 × h + 2/3 × π × r^3
= 1/3 × 22/7 × 9 × 6 + 2/3 × 22/7 × 27
= 113.12 cubic inches
Yes, it is reasonable. If a painter paints a fourth of a room in a fourth of a day, well that means in two-fourths of a day he would paint two-fourths of a room. Same for three fourths and four fourths, which is equal to one day. If he or she can paint one room in one day, it'd be reasonable to say that he can paint 7 rooms in 7 days.
