C. Again, assume that we can't produce more than 1,000 un necessarily some x value, let's call it C, for which the profit is exactly 0? Explain your answer. 2. For the following: A. Produce a function f(x) that satisfies the following conditions: 1. Its domain is all real numbers. 11. It has no maximum and no minimum on the interval (1, 3). III. It satisfies f(1) = 1 and f(3) = -1, but there does not exist a c between 1 and 3 such that f(x) = 0. B. Construct a function f(x) that satisfies the following conditions: C. fis continuous for all x.
Answer:
C. Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)
Step-by-step explanation:
I am not sure about number two sorry.

Find the third degree polynomial function that has an output of 40 when x = 1, and has zeros - 19 and -i?
Answer:
f(x) = x³ + 19x² + x + 19
Step-by-step explanation:
Zeros: -19 , -i, complex conjugate root: +i
Function: (x+19)(x+i)(x-i) = 0
(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19
check: when x = 1
f(1) = 1 + 19 + 1 +19 = 40

What does it mean to say two variables are positively associated
Answer:
A positive correlation is a relationship between two variables in which both variables move in the same direction. Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases.
Susan is choosing tween two cell phone plans that offer the same amount of free minutes.
Plan A charges $29.99 per month with additional minutes costing $0.45
per minute.
Plan B charghes $39.99 a month with addtional minutes costing $0.40 per minute. If the equation for Plan A is
0.45x + 29.99 and the equation for plan E
is 0.40x+ 39.99, then how many addtional minutes, x, will it take for the two plans to cost the same?
Answer:
200
Step-by-step explanation:
You can simply just graph it and see where the points intersect, or you can do it algebraically.
0.45x+29.99=0.40x+39.99 subtract 29.99 both sides
0.45x=0.40x+10.00 subtract .40x both sides
0.05x=10.00 divide both sides by 0.05
x=200

2x+3y=24 in slope intercept form
Answer:
3y = -2x + 24
y = -2/3x + 8
Step-by-step explanation:
Answer:
The slope-intercept form is y=mx+b y = m x + b
Step-by-step explanation:
where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .

A company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50
Based on this information, which graph best shows this relationship between the cost y, and the number of cubic yards, X?
The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.
Given that, a company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50.
What is graph?In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Let the total cost be y and the number of cubic yards be x.
Now, the equation to represent the given situation is y = 50+50x
By substituting x = 0, 1, 2, 3, 4, 5,....we get
y = 50+50(0) = 50
y = 50+50(1) = 100
y = 50+50(2) = 150
y = 50+50(3) = 200
y = 50+50(4) = 250
So, the coordinates to plot the graph are (0, 50), (1, 100), (2, 150), (3, 200) and (4, 250) and so on.
The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

f(x)=2+|x-3| for all x than the value of the derivative of x=3 is
The derivative at x = 3 does not exist.
To see why, recall the definition of absolute value:
[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]
If x - 3 ≥ 0, then
2 + |x - 3| = 2 + (x - 3) = x - 1
and the derivative of this piece is 1 for all x > 3.
If x - 3 < 0, then
2 + |x - 3| = 2 - (x - 3) = 5 - x
and its derivative is -1 for all x < 3.
The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Answer:
m∠1 = 52, m∠2 = 60
Step-by-step explanation:
68 and ∠2 are interior angles. 128 is exterior angle.
Formula : -
Sum of two interior angles = Exterior angle
68 + ∠2 = 128
∠2 = 128 - 68
∠2 = 60
∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,
∠1 + 128 = 180
∠1 = 180 - 128
∠1 = 52

Kelly bought a soda for three dollars and 7 candy bars when she went to the movies. She spent a total of $21. How much did each candy bar cost? Write out and solve. Show work
Answer:
$2.57
Step-by-step explanation:
Create an equation.
7x + 3 = 21
Subtract 3 from both sides of the equation.
7x = 18
Divide 7 from both sides to find x.
18/7 = x,
x = 2.57

Martin has 128 pencils that he is putting
into boxes. Each box holds 6 pencils. If he
puts all the pencils into boxes, how many
more pencils will he need to fill the last box
completely?
128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3
Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3
