52 seats. Just subtract two from your previous answer (86-2=84, 84-2=82...)
Answer:
1) 102.7 meters
2) 11
Step-by-step explanation:
1) -4.9x² + 75x = -4.9x² + 50x + 38
25x = 38
x = 1.52 s
Height = -4.9(1.52)² + 75(1.52) = 102.67904 m = 102.7 m
2) f(x) = x² + 3x - 2
f(2) = 2² + 3(2) - 2 = 8
f(6) = 6² + 3(6) - 2 = 52
Average rate of change:
(52-8)/(6-2) = 11
Answer:
Step-by-step explanation:
Y2 + 72 ÷ x - 12
Putting values of x = 9 and y = 5 in the equation
(5)^2 + 72 ÷ 9 - 12
25 + 72 ÷ 9 - 12
25 + 8 - 12
33 - 12
= 21
