A human cannonball is an act where a performer is launched through the air. The height of the performer can be modeled by h(x)=−0.004x^2+x+19, where ℎ is the height in feet and is the horizontal distance traveled in feet. The circus act is considering a flight path directly over the main tent. If the performer wants at least 5 ft of vertical height clearance, how tall can the tent be? Round your answer to the nearest foot.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.

the answer is -1 1/5, also a
