Answer:
Step-by-step explanation:
ax² + bx + c = y
Plug in data points to get a system of equations in three unknowns.
(0.5,18): 0.25a + 0.5b + c = 18
(1,24): a + b + c = 24
(1.5,22): 2.25a + 1.5b + c = 22
Solving the system: a = -16, b = 36, c = 4
y = -16x² + 36x + 4
When x = 1.7, y = -16·1.7² + 36·1.7 + 4 = 18.96 ft

Answer:
The area 2730 possible arrangements of first, second, and third place.
Step-by-step explanation:
The order in which the students finish is important. For example A, B and C is a different finishing order(outcome) than B, A and C. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
3 from a set of 15. So
The area 2730 possible arrangements of first, second, and third place.
