Answer:
SA = π3^2 + π3(7.5)
Step-by-step explanation: r is radius and L
is r*l/2
so 3*5/2=15/2=7.5
seriously look at a problem more carefully and memorise your formulas!
The answer is c because you need to multiply both numbers inside the parentheses by the number on the outside
16m/s * 8s = 128m Multiply out the time to get the total displacement from the descent.
128m-71m = 57m Find the displacement from the descent to the ascent and then add that to 1364m to get your answer.
1421m
Answer:
a. p(x<= 5) = .15 + .4 + .25 = .8
C. .4(4.2) = 1.68
5.4(1-.4) = 3.24
3.24 + 1.68 = 4.92 ,, 4.92 > 4.55 so short is better
