<u>Answer:</u>
The total cost for the family was $16
<u>Step-by-step explanation:</u>
Given:
Number of adult tickets = 2
Number of children ticket = 3
To Find:
The total cost of the family = ?
Solution:
The total cost of the family = cost for buying 2 adult tickets + cost of buying 3 children tickets
=>
=> 10 + 6
=> 16
Answer:
Step-by-step explanation:
We can solve this in either of two approaches: Mathematically or Graphically.
<u>Mathematically</u>
y=-(3/4)(x-4)^2+12 where y is the height of the ball, and x is the time, in seconds.
We want to know how many seconds for the height to be 0, so y=0.
0 = -(3/4)(x-4)^2+12
-12 = -(3/4)(x-4)^2
12*(4/3) = (x-4)^2
16 = (x-4)^2
x = 8 and 0 (the initial point).]
It will reach the ground in 8 seconds
<u>Graphically</u>
Plot the function and find the time, x, when the graph passes through the x axis (after t = 0). Attached.
