Answer:
C. P(x) = -0.6x3 + 300x^2 – 700x + 600
Step-by-step explanation:
The profit function is P(x) = -0.6x³ + 300x² - 700x + 600.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given,
Cost function, C(x) = 500x² + 400x
Revenue function, R(x) = -0.6x³ + 800x² - 300x + 600
Profit is the difference between the revenue and the cost.
Profit function is therefore the difference of revenue function and the cost function.
P(x) = R(x) - C(x)
P(x) = (-0.6x³ + 800x² - 300x + 600) - (500x² + 400x)
= -0.6x³ + 800x² - 300x + 600 - 500x² - 400x
= (-0.6x³) + (800x² - 500x²) + ( - 300x - 400x) + 600
= -0.6x³ + 300x² - 700x + 600
Hence the profit function of the granola bar company is P(x) = -0.6x³ + 300x² - 700x + 600.

I am a multiple of 6. I am also a multiple of 4. I am less than 30.
Who am I?
Answer:
12 and 24
Step-by-step explanation:
First, we need to list out the common multiples of 4 nd 6, less than 30
[tex]4 = 0.4,8,12,16,20,24,28[/tex]
[tex]6 = 0.6,12,18,24[/tex]
Then, we list out the common multiples
[tex]Common\ Multiple = 12,24[/tex]
Since, only 12 and 24 fall in this category.
Then the number is either 12 or farm
The graph of the SLOPES of the red function has which color?
Answer: Orange.
Step-by-step explanation:
The graph of the slopes of the red function is equal to the derivate of the red function.
First, let's analyze the red function (from left to right).
First we can see that the red function is positive, and it decreases (so we must have a negative slope here).
Then we can see a little inflection point where the red function seems to be constant for a bit (here the slope must become zero for a little bit).
Then the red function keeps decreasing (so the slope is negative again).
Then the graph of the slope is:
Negative, then it increases to zero, and it decreases again.
The only graph that does this is the orange one, so the answer is orange.

in 154 N38 what digit should be replaced to N to make the number divisible by 3,6 and 9?
Answer:
[tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.
Step-by-step explanation:
In Number Theory there is a rule of thumb which states that sum of digits of a multiple of 3 equal 3 or a multiple of three. If we know that [tex]n = 154N38[/tex], then its sum of digits is:
[tex]x = 1 + 5+4+N+3+8[/tex]
[tex]x = 21+N[/tex] (Eq. 1)
We have to determine which digits corresponds to multiples of three, there are four digits:
N = 0
[tex]x = 21+0[/tex]
[tex]x = 21[/tex] ([tex]3\times 7 = 21[/tex])
N = 3
[tex]x = 21+3[/tex]
[tex]x = 24[/tex] ([tex]3\times 8 = 24[/tex])
N = 6
[tex]x = 21+6[/tex]
[tex]x = 27[/tex] ([tex]3\times 9 = 27[/tex])
N = 9
[tex]x = 21+9[/tex]
[tex]x = 30[/tex] ([tex]3\times 10 = 30[/tex])
We get the following four distinct options: 154038, 154338, 154638, 154938. Now we find which number is divisible by 6 and 9 by factor decomposition:
[tex]154038 = 2\times 3\times 25673[/tex]
[tex]154338 =2\times 3\times 29 \times 887[/tex]
[tex]154638 = 2\times 3\times 3\times 11\times 11\times 71[/tex]
[tex]154938 = 2\times 3\times 7\times 7\times 17\times 31[/tex]
It is quite evident that [tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.

A basketball player stands near the middle of the court and throws the ball toward the basket.
The path of the ball is a parabola. The ball leaves the player's hands at a height of 6 feet above the ground. The
ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.
Write a function to represent the height of the ball in terms of its distance from the player's hands?
Answer:
A function to represent the height of the ball in terms of its distance from the player's hands is [tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
Step-by-step explanation:
General equation of parabola in vertex form [tex]y= a(x-h)^2+k[/tex]
y represents the height
x represents horizontal distance
(h,k) is the coordinates of vertex of parabola
We are given that The ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.
So,(h,k)=(18,12)
Substitute the value in equation
[tex]y=a(x-18)^2+12[/tex] ---1
The ball leaves the player's hands at a height of 6 feet above the ground and the distance at this time is 0
So, y = 6
So,[tex]6=a(0-18)^2+12[/tex]
6=324a+12
-6=324a
[tex]\frac{-6}{324}=a[/tex]
[tex]\frac{-1}{54}=a[/tex]
Substitute the value in 1
So,[tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
Hence a function to represent the height of the ball in terms of its distance from the player's hands is [tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
(7x +6) - (5x - 4) = 180
Answer:
x= 85
Step-by-step explanation:
(7x+6)-(5x-4)=180
There is a negative 1 between the two parenthesis
-1(5x-4)
-5x+4
Now plug it back into the equation and take out the parenthesis
7x+6-5x+4= 180
2x+10=180 Now we can solve
-10 -10
2x= 170
2x/2 = 170/2
x= 85

Becuase he is given 100 dollars and he uses 20 dollars a day, so you put x with 20 to calculate how many days that he can spend $20 on
Day 1: money spent = 20
Day 2: total money spent = 20+20 = 2*20
So, for x days, total spent money should be 20*x = 20x
At an instant, say, after x days.
=> saving = total amount - spent
=> money left = 100 - 20x
=> y = 100 - 2x
=> y = - 2x + 100

Answer:
which type of equation just tell we are here to help if we can
Answer: Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.
If the word "is" or "are" is included in the description, that is equivalent to an equal sign.
Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.
"From" and "difference" are clues that there is subtraction.
"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.
"Ratio," 'into' "per" and "among" are clues to division.
Use a letter x, y, d, t, or whatever helps identify the
Step-by-step explanation: Without a specific situation, it is impossible to give a specific answer.
Examples: The total number of seats in the auditorium is 125. 75 tickets have been sold already. How many more tickets are left. (This is the unknown)
The Total is the given 75 plus the unknown.

How to determine the graph that represents an increasing functionFor a graph to represent an increasing function, then as the input values increases, the output values must also increase
This means that:
As the x values increases, the y values must also increase
Hence, the graph that best represents an increasing function is (a)
This is so because as x increases from 0 through 2.5 to 4, y increases from 0 through 1 to 3
