The given equation is -3x²+240x-800
The maximum of the function is given when
where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have
Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
Answer:
The 1st the 3rd and 4th are the answers
Step-by-step explanation:
Edgen
First we will divide to se how many boxes there will be.
200 ÷ 24 = 8.333......
So there would be 9 boxes cause there is 1 box that is not FULL.
Next we will multiply.
24 × 8 = 192
Subtract:-
200 - 192 = 8
So there are 9 boxes. The 9th box has 8 books.
Hope I helped ya!!
Not sure I understand this but
5x+2=0
5x = -2
x = -2/5
Or
x = -.4
Answer:
y = (x-3) ^2 +7
Vertex (3,7) minimum
Step-by-step explanation:
y=x^2-6x+16
The equation of a parabola in vertex form is
y = a(x - h)2 + k , where (h, k) is the vertex and a tells us where it opens up or down a>0 opens up and a < 0 opens down
First complete the square
Take the coefficient of the x term, divide by 2 and square it
-6 /2 = -3
(-3)^2 = 9
Take the 16 and split it into 9 and 7
y=x^2-6x+9 +7
y = (x-3) ^2 +7
The vertex is (3,7) and a=1
Since a =1, this opens up and if it opens up, the vertex is a minimum
