Step-by-step explanation:
B = 11 x 7 = 77
h = 4
V = 77 x 4
V = 308

1800 laps in 12 weeks
1800/12 = 150 laps in 1 week
150/5 = 30 laps a day
30 laps in 45 minutes
x laps in 60 minutes
x = (30*60)/45 = 40 laps per hour
U(x)=-2x²+3
v(x)=1/x →→ range of (uоv)(x, BUT range (uov)(x = u(v(x)), then :
u(v(x)) = -2(1/x²) + 3 →→u(v(x)) = -2/x² + 3
The range of -2/x² + 3 = {x∈R/x≠0}
Answer:
x= 11/7 + 3y/7
