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
40x=356000 x= 8900 applications
you make x the number of total applications

Step-by-step explanation:
To rewrite something as a decimal, simply divide the numerator and denominator.
-33 / 25 = -1.32
So -33/25 = -1.32
Answer:
The third answer: x+1
Step-by-step explanation:
Remember when writing roots, the signs are backwards. This is because you start with (x-__) and fill in the root.
So for x = -1, it'll be written as (x+1) [aka (x- -1)]
For x = -3, it'll be written as (x+3)
For x = 5, it'll be written as (x-5)
The only answer that is one of these is the the third answer
