Answer: It should be 42.5 since 68 divided by 8 times 5 equal that
F(x) = -x^2 + 6x + 6
where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds
rate of change of a distance is speed
at x=5, distance = 11
at x=2, distance = 14
so average rate of change = (14-11)/(5-2) = 1
so ans is D
Answer:
D. 13
Step-by-step explanation:
54 ÷ 3 = 18 (your age in 5 years)

Answer: P(26,5).
That is all the possible combinations of 5 letters made out from 26 letters.
That is 26! / [ 5! ( 26 - 5)! ] = 26! / [5! 21! ] = 26*25*24*23*22*21! / [ 5! 21!] =
= 26*25*24*23*22 / [5*4*3*2*1] = 65,780 arrangements.
