Answer:
When written in "vertex form":
• (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.
• the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).
• the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).
• notice that the h value is subtracted in this form, and that the k value is added.
If the equation is y = 2(x - 1)2 + 5, the value of h is 1, and k is 5.
If the equation is y = 3(x + 4)2 - 6, the value of h is -4, and k is -6.

Answer:
$8.65×10^3
Step-by-step explanation:
The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.
West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4
= (5.38 -1.46 -2.38 -0.675)×10^4
= 0.865×10^4 = 8.65×10^3
West raised $8.65×10^3.

Answer:
Children = 137
Adults = 215
Step-by-step explanation:
The admission fee at a water park is $12.50 for children
and $25.00 for adults.
On a certain day, 352 people entered the park and the admission fees collected totalled $6,687.50
Let the number of children admitted be x ,
and the number of adults admitted be y.
This forms a simultaneous equation:
x + y = 352 ... (i)
$12.50x + $25.00y = $6,687.50 ... (ii)
Multiplyng (i) by 12.50 and (ii) by 1 we get;
12.5x + 12.5y = 4400 ... (i)
12.5x + 25y = 6,687.5 ... (ii)
Subtracting (ii) - (i) we get;
12.5y = 2687.5
y = 215
So the number of adults admitted = 215
And the number of children admitted = 352 - 215 = 137
