Answer:
-12°F
Step-by-step explanation:
2 P.M
-35° F + 29° F= -6° F
The temperature had risen by 29°F meaning it went up by 29.
Adding negative 35 and positive 29 is the same as subtracting 35 from 29.
29 - 35 = -6
6 P.M
-6° F - 18°F = -12°F
The temperature had fallen by 18°F meaning it went down by 18°F.
p.s don't forget the label °F
36.9
it might be wrong but at least i tried
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
