Answer:
Step-by-step explanation:
In vertex form, the equation is
y = a(x-h)^2 + k
So just read off the values!
Answer:
Step-by-step explanation:
Volume of rectangular prism = l*w*h
Number of tickets: T.
Number of customers: c
Initially the number of tickets is T0=150, when the group hasn't sold any tickets (c=0). Then the graph must begin with c=0 and T=150. Point=(0,150). Possible options: Graph above to the right and graph below to the left.
They sell the tickets in pack of three tickets per customer c, then each time they sell a pack of three tickets to a customer, the number of tickets is reduced by 3 (-3c). Then the number of tickets, T, the group has left after selling tickets to c customers is:
T=150-3c→T=-3c+150
For T=0→-3c+150=0→150=3c→150/3=c→c=50. The graph must finish with c=50, T=0. Final point=(c,T)=(50,0)
Answer:
The correct graph is above to the right, beginning on vertical axis with T=150 and finishing on horizontal axis with c=50.
The correct equation is T=-3c+150
Answer:
Step-by-step explanation:
- For a horizontal compression, we multiply whole numbers greater than 1 in front of
of the given function. - For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of of the function.
For example,
If we wanted to <u>horizontally compress</u> 
, we would multiply by 4 to get 
, and
if we wante to <u>horizontally expand</u> , we would multiply by 
to get 
Since this question asks for horizontal compression, we multiply the of the function by 4. So the function we need is 
. The second choice is correct.
Answer:
D. 13000 is the correct option out of the choices!
