Answer:
y = -3x + 3
Step-by-step explanation:
Perpendicular slope: -3
y -(-3)= -3(x-2)
y+3= -3x + 6
y = -3x + 3
Answer:
Answers are listed hoping that they make sense XD
Step-by-step explanation:
1. -0.5
2. 7
3. -23
I just substituted the value given from x and solved for y. I hope that is what the question is asking for.
Hope this helps :)
Answer:
Car b
Step-by-step explanation: Because it’s going higher on the graph because it’s going more straight than car a which is going more sideways
Answer:
38.5
Step-by-step explanation:
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
