: A cannonball is launched from the deck of a pirate ship. The function h(t)=−16 t 2 +160t+25 h(t)=-16t2+160t+25 represents the height, h in feet, of the cannonball t seconds after being fired. Round any decimals to the tenths. What is the maximum height of the cannonball?

where are the choices?

it is c, trust i got your back lol

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
