Answer:
See below in bold.
Step-by-step explanation:
A). s(t)= -16t^2+64t+200
Converting to vertex form.
s(t) = -16 (t^2 - 4t) + 200
s(t) = -16 [(t - 2)^2 - 4] + 200
s(t) = -16(t - 2)^2 + 64 + 200
s(t) = -16(t - 2)^2 + 264
The maximum height is after 2 seconds and it is 264 feet.
B) The ball hits the ground when s(t) = 0 so we have:
-16t^2+64t+200 = 0
x [-64 +/- sqrt (64^2 - 4*-16*200) ] / -32
x = 6.06, -2.06
So the answer is 6.06 seconds.
The correct answer is D.
The LCD, least common denominator, is the smallest denominator that both denominators will go into. The LCD of 5 and 7 will be 35; the variable portion will be b³c, since that is the smallest thing the second fraction can go into.
This gives us a denominator of 35b³c.
The price is a linear growth and the constant growth rate is $0.65. To get that as the constant I subtracted 13.25 and 6.75 to get 6.5. After subtracting, I divided 6.5 by 10 to get .65 or $0.65.
G (z)= 3z - 6
3(-3) - 6 = -15 = (-3,15)
3(-2) - 6 = -12 = (-2,-12)
3(-1) - 6 = -9 = (-1,-9)
3(0) - 6 = -6 = (0,-6)
3(1) - 6 = -3 = (1,-3)
3(2) - 6 = 0 = (2,0)
3(3) - 6 = 3 = (3,3)
For the table separate the equations in a column by each equal sign. For each row separate with every line.
Hope this helps
Answer:
the answer is 2.
Step-by-step explanation:
This is because the interest rate is if he had $1 in the account for a year you would add the 18% or in decimel form 0.0018 do that to the 15th to get 15 years and multiply that by 5000 because that was the ammount of money he put in so 5000(1*0.0018)15 or 0.0018^15*5000
