Answer:
a) The absolute maximum is 401 and the absolute minimum is 9.
b) The absolute maximum is 349 and the absolute minimum is -99.
c) The absolute maximum is 401 and the absolute minimum is -99.
Step-by-step explanation:
The absolute minimum and absolute maximum values are determined with the help of the First and Second Derivative Tests:
FDT
The roots of the function are: and . Each point is evaluated in the second derivative of the function:
SDT
(Absolute minimum)
(Absolute maximum)
The values for each extreme are, respectively:
Now, each interval is analyzed herein:
a) The absolute maximum is 401 and the absolute minimum is 9.
b) The absolute maximum is 349 and the absolute minimum is -99.
c) The absolute maximum is 401 and the absolute minimum is -99.
First, convert the 90 feet of the real plane to inches so that you can find the scale:
90 x 12 = 1080
Now, divide the inches of the real wing span by the inches of the model wing span:
1080/18
Now you want to simplify. The easiest way to start is dividing the top and bottom by 2:
540/9
Now try dividing the top and bottom by 9:
60/1
So your scale is 1 inch of model airplane to 60 inches of actual airplane.

Answer:
w = 5
Step-by-step explanation:
24w = (14)10
2w + 4 = 10 + 4
2w = 10
w = 5
Answer:
(4x - 3)(3x² + 1)
Step-by-step explanation:
Given
12x³ - 9x² + 4x - 3 ( factor the first/second and third/fourth terms )
= 3x²(4x - 3) + 1(4x - 3) ← factor out (4x - 3) from each term
= (4x - 3)(3x² + 1) ← in factored form
