- Y=X(12)-4 SO 12-4 IS <u>8</u>
- Y=X(14)-4 SO 14-4 IS <u>1</u><u>0</u>
- Y=X(17)-4 SO 17-4 IS <u>1</u><u>7</u>
The general solution of a differential equation of the form ay'' + by' + cy is given by Ae^mx + Be^nx; where m and n are the root of the quadratic equation ax^2 + bx + c
The general solution of <span>y'' + 4y' is given by </span><span>Ae^mx + Be^nx; where m and n are the root of the quadratic equation x^2 + 4x = 0
x(x + 4) = 0
x = 0 or x = -4
Therefore, the general solution is Ae^(-4x) + Be^0x = Ae^(</span>-4x) + B
Answer:
Point (0,0) is a local minimum and point (8,4) is a local maximum.
The function is incrasing for all ![0](https://tex.z-dn.net/?f=0%3Cx%3C8)
The function is decreasing for all ![x8](https://tex.z-dn.net/?f=x%3C0%5Ctext%7B%20or%20%7Dx%3E8)
Step-by-step explanation:
Plot the graph of the function
(see attached diagram for details).
A local extremum is a local maximum or a local minimum.
From the graph of the function, you can see that point (0,0) is a local minimum and point (8,4) is a local maximum.
The function is incrasing for all ![0](https://tex.z-dn.net/?f=0%3Cx%3C8)
The function is decreasing for all ![x8](https://tex.z-dn.net/?f=x%3C0%5Ctext%7B%20or%20%7Dx%3E8)
Answer:.
Step-by-step explanation:
Answer:
A) $71,26
B) 84.207
Step-by-step explanation:
For the part A as the resident has use 40.000 gallons we need to divide that number in 741
=40.000/741=53,98
Thats the quantity of portions and every portion is $1,32 than we multiply
=53,98*1,32
=$71,26 (the bill for the resident)
For the part B you have $150 for the bill and every portion price is $1,32 than first we need to know how many portions the custumer can buy
=150/1,32
=113,64 portions
And every portion has 741 gallons, then we multiply to find the total gallons
=113,64*741
=84.207
