Answer:
what ?
Step-by-step explanation:
Answer:
66 minutes
Step-by-step explanation:
<u>Solve for speed</u>
speed = distance / time
speed = 6 / 44
<u>Substitute in speed to second equation and solve for time</u>
distance / speed = time
9 / (6/44) = time
66 = time taken
Answer:
1/2bxh (half a base times the height)
Step-by-step explanation:
Answer:
Domain: t≥0
Range:h(t) ≤ 0.85
Step-by-step explanation:
The domain of a function is all the valid values you can enter into the function. Because time can't be negative the domain is t>0. The range or h(t) is the result, because the object can't go through the ground, it can't be less than zero. 0≤h(t)
0≤-4.87t^2+18.75t
0≤-4.87t+18.75
-18.75≤-4.87t
which is approx.: 0.85≥t or t≤0.85
