This is a quadratic equation whose graph is a parabola that opens down.
When does the rocket reach its highest point? Note that at that point it will stop ascending, momentarily stop, and then begin descending. Note also that that point is the vertex of the parabola.
The easiest way to find that time value is to use the formula t = -b/(2a).
Here, t at max height is t = -(144) / (2*[-16]) = 4.5 sec (answer.
What's the rocket's height there? To answer this, sub 4.5 sec for t in the given equation, <span>h(t) = -16t^2 + 144t.
Note: Please use " ^ " to indicate exponentiation:
</span> -16t^2 + 144t (not -16t2 + 144t)

Answer:
C. g(x) = 3
Step-by-step explanation:
f(1) = 1 and g(1) = 3
g(1) is 3 times more than f(1)
So, g(x) = 3
Answer:
D) 1980 to 2000
Step-by-step explanation:
Finding the average rate of change in each interval to determine the greatest one.
Production per interval
1950-1960 = = 10 million
1960-1970 = = 20 million
1970-1980 = = 30 million
1980-2000 = million
Rate of change (1950-1960)=
Rate of change (1960-1970) =
Rate of change (1970-1980)=
Rate of change (1980-2000)=
∴ rate of change between 1980 to 2000 is 126.78%
