A function that models the profit for a new pet-monitoring system shows that there is no profit made until the price reaches
$95 per unit, a maximum profit at a price of $140 per unit, and no profit at a price over $185 per unit. Which graph models
the function?
Graphing
Answer:
The graph that best fits this model of profit and price per unit is attached to this solution.
Step-by-step explanation:
A couple of graphs are missing from the question. According to the full question as obtained online, there are a number of graph options, and we are expected to pick the best option. I would not add all the other graphs to limit the chances of deletion due to violating community guidelines.
The function is to model the profits of a new pet-monitoring system, so, if the profits are y and x is the price per unit, y = f(x)
The profits vary as the price per unit varies, there is no profit made until the price reaches
$95 per unit, a maximum profit at a price of $140 per unit, and no profit at a price over $185 per unit.
This description of the curve shows that y is negative at values of x less than $95, then the profits increase when x varies between $95 and $140. The profits reach a maximum at $140 and then the profits start to decline as x increases again, the profits go to 0 at x = $185.
This description shows that the function is a quadratic function with a graph that is n-shaped, peaking at x=185 and the graph crosses the x-axis at x=95 and x=185.
The most fitting graph for this model is attached to this solution provided.
From the graph, all the descriptions above are evident.

At the beach, 11% of people have white towels and 53% have blue towels. If
the rest have red, what percentage of the people at the beach have red
towels?
Answer here
SUBMIT
ASAP help plz
Answer:
36 percent.
Step-by-step explanation:
We have been given that 11 percent of people of the peach have white towels, and 53 percent have blue towels.
With this information, we can find the remaining percentage of people that have red towels.
Recall that the total percentage is always 100 percent.
lets make r for the percentage of people that have red towels.
You can solve it by changing it to fraction, decimal, or just keep it at percent.
I will show you all of the possible ways.
Percent:
11 percent plus 53 percent plus r =100 percent
combine the like terms, or add 11 plus 53 to simplify the equation.
You have 64 percent plus r =100 percent Our goal is to isolate r, so subtract both sides by 64 percent.
100-64 is 36 percent.
r=36 percent of people who have red towels.
With fractions.
Write it as 11/100 plus 53/100 plus r/100= 100/100.
Combine the fractions.
64/100 plus r/100=100/100.
Subtract both sides by 64/100.
You are left with r=36/100, 9/25, or 36 percent.
With decimals.
11 percent as a decimal is 0.11. Just move the decimal spot 2 times. In 11, since you can write it as 11.0, you move it to the right twice.
53 percent is 0.53.
r is r.
100 percent is 1.
0.11 plus 0.53 plus r=100
Combine or add 0.53 and 0.11. That is 0.64.
Subtract both sides by 0.64.
You get r to be 0.36 or 36 percent.
I hope this helps, and I hope you have a good day!

Which of the binomials below is a factor of this trinomial? x2 - x-12 A) x+6 B) x+4 C) x-4 D) x-6
Start by setting up your two sets of parenthses.
X² breaks down into x and x.
What we are looking for is factors of the constant term
that add to the coefficient of the middle term.
The question is, what is the coefficient of the middle term
in this problem if there is nothing written in front of the x.
Well if there is nothing written there,
the coefficient is understood to be 1.
So what we are looking for are factors of -12 that add to -1.
Factors of -12
+12 · -1
-12 · +1
+6 · -2
-6 · +2
+4 · -3
-4 · + 3
We can see that -4 and +3 add to -1.
So they go in the second position of each binomial.
This gives us (x - 4)(x + 3) as our answer.

Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55. Step 1: Write the ordered pairs (35, 41.45) and (65, 55.55). Step 2: Find the slope. M = StartFraction 55.55 minus 41.45 Over 65 minus 35 EndFraction = 0.47 Step 3: Find the y-intercept to write the equation in slope intercept form. Y minus 55.55 = 0.47 (x minus 35). Y minus 55.55 = 0.47 x minus 16.45. Y = 0.47 x + 39.1. Which explains the error that Lila made? Lila made in error in Step 1 by reversing the ordered pairs. Lila made an error in Step 2 by not using the slope formula. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair. Lila made an error in Step 3 when she did not use the distributive property correctly when multiplying.
Answer:
The answer is C. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.

The y intercept of the problem is equal to 25+14.1/30*x.
What is total cost?The total cost is the sum of the fixed cost and the variable cost to make a product.
How to find y-intercept?x is showing no. of bruchers
y is showing total cost.
Total cost for 35 bruchers=41.45
Total cost for 65 bruchers=55.55
The points are (35,41.45), (65,55.55)
The y intercept can be calculated as :
y-41.45=(55.55-41.45/65-35)*(x-35)
30y-14.1x=750
y=25+14.1/30*30
Hence the value of y intercept is 25+14.1/30*30.

Consider the reduction of the rectangle. A larger rectangle has a length of 18 inches and width of 8 inches. A smaller rectangle has a length of x inches and width of 3 inches. Write a proportion and then solve to find the missing measure of the reduced rectangle. What two ratios can be used in the proportion? What is the value of the missing measure?
Answer:
18/8 = x/3
x = 6.75 inches (length)
Step-by-step explanation:
Hi, to answer this question we have to write 2 ratios using the information given:
A larger rectangle has a length of 18 inches and width of 8 inches.
Inches /width = 18/8
So, for a rectangle that has a length of x inches and width of 3 inches the ratio is :
x/3
Solving for x:
18/8 = x/3
18/8 (3) =x
6.75 in= x

B:into itself,and thought no more can trace
C: Are graven,till the characters be grown
D: Whereon the linements of that dead face
explain answer this question is English
Answer:
A: Tis the melodious hue of beauty thrown .
Explanation:
An appeal to the sense of hearing and sight will be something that presents an act that gives the readers a sense of the sounds in the writing. While an appeal to the sense of sight will present an image or a form of the picture to the readers. These types of sense appeals are used by writers to engage their readers' interest and keep them hooked.
In Percy Bysshe Shelly's poem "On the Medusa of Leonardo Da Vinci in the Florentine Gallery", the poet talks about the goddess Medusa but most importantly talks about the painting of "Medusa" by Da Vinci. The poem structured in the iambic pentameter scheme presents an image of Medusa and also how she was depicted by Da Vinci in his work. Out of the given options from the second stanza of the poem, the line that appeals to the sense of hearing and sight is "Tis the melodious (hearing/ sound) hue of beauty thrown (sight)".
Thus, the correct answer is option A.

Graphing Linear Inequalities
This is a graph of a linear inequality:
linear inequality y <= x +2
The inequality y ≤ x + 2
You can see the y = x + 2 line, and the shaded area is where y is less than or equal to x + 2
Linear Inequality
A Linear Inequality is like a Linear Equation (such as y = 2x+1) ...
... but it will have an Inequality like <, >, ≤, or ≥ instead of an =.
How to Graph a Linear Inequality
First, graph the "equals" line, then shade in the correct area.
There are three steps:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
Let us try some examples:
Example: y≤2x-1
1. The inequality already has "y" on the left and everything else on the right, so no need to rearrange
2. Plot y=2x-1 (as a solid line because y≤ includes equal to)

Step-by-step explanation:
what are the coordinates of that center of a circle if the endpoints of its diameter are a(8,-4) and b(-3,2)?
The coordinates of that center of a circle with endpoints of its diameter at a(8,-4) and b(-3,2) is (2.5, -1)
The standard equation of a circle is:
(x - a)² + (y - b)² = r²
where (a, b) is the center of the circle and r is the radius of the circle.
Given the diameter endpoints at a(8,-4) and b(-3,2), let (x, y) be the center of the circle, hence:
[tex]x=\frac{8-3}{2} =2.5\\\\y=\frac{-4+2}{2}=-1[/tex]
Hence the center of the circle is at (2.5, -1)
The coordinates of that center of a circle with endpoints of its diameter at a(8,-4) and b(-3,2) is (2.5, -1)
Use the table to identify the values of pand q that should be used to factor x2
- 3x - 10 as (x + p)(x + 9).
Answer:
A
p = -5 and q = 2 or p = 2 and q = -5
Step-by-step explanation:
Technically, you don't need the table to help you out here. If you solely just factor out x²-3x-10, you would get (x-5)(x+2). So one variable would always have to be -5 and the other variable would always have to be 2.

$3000 is deposited in an account
that pays 5% interest,
compounded quarterly, for 10
years. How much more would be
in the account if the interest were
compounded continuously rather
than quarterly?
Answer:
$15.30
Step-by-step explanation:
The formula for the account balance with continuous compounding is ...
A = Pe^(rt)
For the given values, this is ...
A = $3000·e^(0.05·10)
A ≈ $4946.16 . . . . balance with continuous compounding
__
The amount with quarterly compounding is ...
A = P(1 +r/n)^(nt)
A = $3000(1 +.05/4)^(4·10)
A ≈ $4930.86 . . . . balance with quarterly compounding
__
The difference is ...
$4946.16 -4930.86 = $15.30
The continuously compounded account would earn $15.30 more in 10 years.

the line ab has midpoint (-2, 4) a has coordinates (3, -2) find the coordinates of b
Answer:
b = (- 7, 10 )
Step-by-step explanation:
Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]
let the coordinates of b = (x, y ) then use the formula and equate to the coordinates of the midpoint, that is
[tex]\frac{1}{2}[/tex] (x + 3) = - 2 ( multiply both sides by 2 )
x + 3 = - 4 ( subtract 3 from both sides )
x = - 7
[tex]\frac{1}{2}[/tex] (y - 2) = 4 ( multiply both sides by 2 )
y - 2 = 8 ( add 2 to both sides )
y = 10
Thus the coordinates of b are (- 7, 10 )
