Alright, so there are 4 reindeer to fill 3 different positions, which is a permutation. If you have a calculator, this can be calculated by finding the nPr function and filling in 4P3 (4 pick 3).
If you don't have a calculator, you can use the formula:
n! / ((n-r)!)
where n is the total number in the set and r is the number chosen
solving that formula:
4! / (4-3)! = 4*3*2*1/1 = 24
Either way, you get the answer of 24.
Answer:
y = 0.7(x^2 - 64x - 576)
Average rate of change = -49.
Step-by-step explanation:
As the x intercepts are -8 and 72 we can write the equation
y = a(x + 8)(x - 72) where a is some constant to be found.
As it passes through point (62, -490) we have, substituting:
-490 = a(62+8)(62-72)
-490 = - 700a
a = 0.7
So the equation of the parabola
y = 0.7(x + 8)(x - 72) or
y = 0.7(x^2 - 64x - 576).
Average rate of change between x = -8 and x = 2
= [0.7(2+ 8)(2 - 72) - 0.7(-8+8)(-8-72)] / (2 - -8)
= -490 - 0 /10
= -49
