Answer:
D. g(x) = 3·x²
Step-by-step explanation:
The given parent function, f(x) = x²
The graph of the function, g(x) is narrower than the graph of the function f(x)
Therefore, the coefficient of the quadratic function is larger than 1
The given point on the parabola, g(x) = (1, 3)
Therefore. when x = 1, g(x) = 3
However, when x = 1, f(x) = 1
Therefore, given that g(x) = a·f(x), we get;
a = g(x)/(f(x)) = 3/1 = 3
g(x) = 3·x²

Answer:
14 : 15 or 2 : 15 pm
Step-by-step explanation:
Time of the appointment = 11: 45 + 2 ½ hours
Jason's appointment is in 2 ½ hours. His appointment is in 2 hours + 1/2 of an hour
1/2 of an hour = 1/2 x 60 = 30 minutes
Remember that 60 minutes make one hour
Time of the appointment = 11:45 + 2:30
+ <u>2 : 30 </u>
13 : 75
we would have to adjust the time derived from the addition because the maximum minutes that exist is 60
To adjust, remove 60 minutes from the minutes and add it to the hour
this gives 14 : 15 or 2 : 15 pm

Answer:
1/(810pi) cm/s
Step-by-step explanation:
V = pi×r²×h = pi×90²×h = 8100pi×h
dh/dt = dh/dV × dV/dt
dV/dh = 8100pi
dV/dt = 10
dh/dt = (1/8100pi) × 10
= 1/(810pi) cm/s
