Answer: 
Step-by-step explanation:
To answer this, we have to use quadratic equations.
We can represent this by using information given to us.
Knowing that a parabola peaks at its vertex, and the flare goes from its launch site (x = 0) and hits the ground 30m from the launch site (x = 30), we know that the flare peaks 15 meters away horizontally from the launch point.
We also know that the y-intercept is 0, because it is fired from the ground.
Knowing that the vertex for the parabola is (15, 200) and the y-intercept is (0, 0), we can model an equation.
Vertex form is:
, where (h, k) is the vertex.
We can plug the y-intercept, (0, 0), into this equation to find a:
Answer:
- 984 adults
- 281 teens
- 492 children
Step-by-step explanation:
Multiply the total by the corresponding percentage to find the number. We assume the percentages have been rounded, so some adjustment is needed in the result of the multiplication.
{adults, teens, children} = 1757 × {.56, .16, .28} = {983.92, 281.12, 491.96}
≈ {984, 281, 492}
The visitors included 984 adults, 281 teens, and 492 children.
It is given that, Shyla had a balance of −$255.25 in her account, and Susan had a balance of −$178.75 in her account.
And absolute value of -255.25 =255.25 which is greater than absolute value of -178.75 which is 178.75. It means , Shyla's account balance is more than Susan's account balance . THerefore, Shyla owes the bank more than Susan .
