Well the position function is:
h(t)=-16t^2+256
It will hit the ground when h(t)=0
-16t^2+256=0 factor out -16
-16(t^2-16)=0 factor difference of squares...
-16(t+4)(t-4)=0, since t>0
t=4 seconds

Answer:
B: BC ≅EC
Step-by-step explanation:
You know that the two angles starting in C are congruent (they're opposite by vertex C).
Given that the B angle and the E angle are congruent, in order for the two triangles to be congruent by A(ngle)S(ide)A(ngle) you want the side inbetween to be congruent. That is BC and EC. Option B
Answer: The cost per person would be $15.20.
Step-by-step explanation: The price $40 per person when you have 5 people, is 8,8x the price per person. So, if you have 6 people more, you have 8,8x6 less in the price.
8,8 x 6 = 52,80.
44 x 5= 220,00. That was the cost for the limo for 5 people.
It means 220,00 - 52,80 = 167,20 (new price for 11 people)
167,20 ÷ 11 (new price per person) = 15,20.
