Answer:
Step-by-step explanation:
If the engine torque y (in foot-pounds) of one model of car is given by y=−3.75x^2+23.2x+38.8
The engine speed is at maximum if dy/dx = 0
dy/dx = -2(3.75)x+23.2
dy/dx = -7.5x + 23.2
since dy/dx = 0
0 = -7.5x + 23.2
7.5x = 23.2
x = 23.2/7.5
x = 3.093
Hence the maximum torque is 3.09 rev/min
Answer:
the answer is 5 because 40 divided by 8 is 5
Answer:
19.9 i think
Step-by-step explanation:
125/3.14=39.8
39.8/2=19.9
hope i helped
Answer: 2000
Step-by-step explanation:
Set up equation
The total signatures she needs is 4 times as many as she has. From this we can create the equation (4n = total signatures)
We know that the total number of signatures is 8000, so plug this into the equation to get 4n = 8000
Solve for n
Now that we have an equation, we can solve for n by dividing both sides by 4
4n = 8000
n = 8000 / 4 = 2000
Final Answer
Fiona has collected 2000 signatures so far
