Answer:
A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Step-by-step explanation:
By definition, Acceleration is the rate of change of Velocity of an object.
I.e it is the( final velocity minus initial velocity ) ÷ by the time it took for the velocity to change.
If we observe the choices only one choice gives us all 3 components (final velocity, initial velocity, time taken for velocity to change), which is :
A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.
Answer:
The maximum profit of $ 10277.32____ can be made when the selling price of the dog food is set to $ _34___ per bag.
Step-by-step explanation:
Profit = Revenue - Cost
P(x) = R(x) -C(x)
= -31.72x^2 + 2,030x
-( -126.96x + 26,391)
Distribute the minus sign
= -31.72x^2 + 2,030x+126.96x - 26,391
Combine like terms
= -31.72 x^2 + 2156.96 x - 26391
This is a parabola. It is facing downwards. The maximum profits is at the vertex ( where the max is)
vertex = h = -b/2a = -(2156.96)/(2*-31.72) = -2156.96/-63.44=34
Evaluate P(x) at x=34 to determine the profit
P(34) = -31.72 (34)^2 + 2156.96 (34) - 26391
-36668.32+73336.64-26391
10277.32
