Answer:
74.82
Step-by-step explanation:
48+38=86 86 X 0.87= 74.82
H(t) = -16t^2 +42t = -16t(t -2.625)
The maximum height will be reached at t=1.3125. It will be
h(1.3125) = 16*1.3125^2 ≈ 27.6 Which corresponding to the 4th selection
If you start from a temperature of -6° C and you need to lower that temperature of 20 more degrees, you have to subtract:

So, the temperature in Antarctica is -26° C
