Answer:
P=−0.001x+3−1800/x
Step-by-step explanation:
Write the problem as a mathematical expression.
P(x)=−0.001x²+3x−1800/x
Divide each term in Px=−0.001x²+3x−1800 by x.
Px/x=−0.001x²/x + 3x/x + −1800/x
Cancel the common factor of x.
P=−0.001x²/x+3x/x + −1800/x
Simplify each term.
P=−0.001x+3−1800/x

Answer:
B
Step-by-step explanation:
Lets go one step at a time
He traveled 5 miles in 10 minutes right?That would already knock out option A because, in 10 minutes it says Keith only traveled 3 miles.
He stops at a gas station for 5 minutesoption C would be incorrect because, he was stationary and that doesn't mean that Keith should be wiggling on the graph.
He travels another 2 miles to reach the office in 5 minutesSo it is between B and D. They both have the time aspect however, B travels farther and D travels backwards.
Therefore, your only possible answer choice would be B.
Find the missing angle measure. PLEASE HELP ASAP
Answer:
Angle 1 is 57 degrees
Angle 3 is 57 degrees
Angle 4 is 123 degrees
Step-by-step explanation:
Cause a straight line is 180 degrees and if angle 2 is 123 degress then angle 3 is 57 degrees and i got that by Subtracting 180-123 =57
Then for angles one you do the same maththat you do for finding angle 3
Then for angles 4 subtract 180-57=123

What are two points that represent Justine's function for the yards left to hike in terms of the hours she's spent hiking?
Answer:
(0,320) and (4,0)
Step-by-step explanation:
The question has missing details. So, I've added the complete question as an attachment.
From the question, we understand that:
Justine started when Michael was 320 yards from the top.
This coordinate can be represented as (0,320)
0 represents the time Justine started and 320 represents the number of yards left.
Every minute, Justine covers 80 yards.
This implies that:
At 1 minute, Justine will have: (320 - 80) yards left
At 2 minutes, Justine will have: (320 - 80 - 80) yards left
At 3 minutes, Justine will have: (320 - 80 - 80 - 80) yards left
At n minutes, Justine will have (320 - 80n) yards left
So, possible coordinates are:
[tex](x_1,y_1) = (0,320)[/tex]
[tex](x_2,y_2) = (1,320-80*1) = (1,240)[/tex]
[tex](x_3,y_3) = (2,320-80*2) = (2,160)[/tex]
[tex](x_3,y_3) = (3,320-80*3) = (3,80)[/tex]
[tex](x_4,y_4) = (4,320-80*4) = (4,0)[/tex]
Answer:
Select any two pairs of values from the given table. But, for simplicity, it’s a good idea to select coordinates with integer values. So, two points that represent Justine’s function for the yards left to hike in terms of the hours she’s spent hiking are (1, 270) and (2, 150).

Can you write the sum, and put it in standard form??
Step-by-step explanation:
[tex] \tt{(4 {x}^{3} + 2x + 6) + (2 {x}^{3} - {x}^{2} + 2) }[/tex]
Remove the unnecessary parentheses.
⟶ [tex] \tt{4 {x}^{3} + 2x + 6 + 2 {x}^{3} - {x}^{2} + 2}[/tex]
Combine like terms. Like terms are those which have the same base. Note that only coefficients of like terms can be added or subtracted.
⟶ [tex] \tt{4 {x}^{3} + 2 {x}^{3} + 2x + 6 + 2 - {x}^{2} }[/tex]
⟶ [tex] \tt{6 {x}^{3} + 2 x + 8 - {x}}^{2} [/tex]
As we are asked to write the answer in standard form , we have to rewrite the expression 6x³ +2x + 8 - x² in such a way that the power of the variables goes from highest to lowest.
[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \tt{6 {x}^{3} - {x}^{2} + 2x + 8}}}}}}[/tex]

A(-4,3) B(2,-1) D(-4,-1) C(2,-5)
Answer:
Step-by-step explanation:
Vertices of the given quadrilateral are A(-4, 3), B(2, -1), C(2, -5) and D(-4, -1)
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of AB = [tex]\frac{3+1}{-4-2}[/tex]
= [tex]-\frac{2}{3}[/tex]
Slope of AD = [tex]\frac{3+1}{-4+4}[/tex]
= Not defined (Parallel to y-axis)
Slope of DC = [tex]\frac{-5+1}{2+4}[/tex]
= [tex]-\frac{2}{3}[/tex]
Slope of BC = [tex]\frac{-1+5}{2-2}[/tex]
= Not defined (Parallel to y-axis)
Slope of AB = slope of DC = [tex]-\frac{2}{3}[/tex]
Slope of BC = slope of AD = Not defined (parallel to y-axis)
As per property of a parallelogram,
"Opposite sides of a parallelogram are parallel and equal in measure"
Therefore, ABCD is a parallelogram.

Answer:
y=90
x= 53
Step-by-step explanation:
Angles x,y and 37, when added together must equal 180. Because they create a straight angle.
the square u see on angle y, indicates its a right angle. Therfore 90.
so 90+37= 127 degrees.
and now we have to find what angle x is, which will make the degree 180.
so u do 180-127= 53 degrees
Answer:
Step-by-step explanation:
x+37=90
x=53
y=90+53
y=143
PLEASE HELP DUE IN 10 MINS Which of the following statements is NOT TRUE based on the expression below?
−4m2 + 2m + 5
A. The constant is 5.
B. There are three terms.
C. The variable in the first term is m.
D. The coefficient in the second term is 2m.
Answer:
D
Step-by-step explanation:
A coefficient is the number before a variable. The D statement isn't true because the coefficient would be 2 instead of 2m. 2m would be the whole term.
Answer:
D
Step-by-step explanation:
The coefficient is the number in front of the variable. the number in front of the second variable is 2, not 2m
The point (4,3.5) is the maximum of the profit function.
A.Explain what the point (4,3.5) represents in terms of the context of the graph.
The function shown describes f(x), the cost (in hundreds of thousands of dollars) of making x bicycles (in thousands).
F(x)=1.25+0.35x
B.what is the cost to make 4,000 bicycles? Show your work.
Compare the slope of the cost function with the graph of the profit function.
C. Explain why the company should plan on making fewer than 4,000 bicycles.
Answer:
A. The point represents the turning point of the graph
B. The cost of making 4,000 bicycles is $265,000
The slope of the cost function, F(x) = 1.25 + 0.35·x, is less than the average slope of the graph of the total profit for sales
C. The company should plan on making fewer than 4,000 bicycles, to maximize profit
Step-by-step explanation:
A. The point represents the turning point after which increase in the x-coordinate values leads to a decrease in the y-coordinate values
B. The cost function is presented as follows;
F(x) = 1.25 + 0.35·x
Where;
F(x) = The cost in hundreds of thousands of dollars of making 'x' (in thousands) bicycles
x = The number of bicycles made in thousands
The cost of making 4,000 bicycles is given by plugging in x = 4(thousand) in F(x) = 1.25 + 0.35·x, as follows;
F(x) = 1.25 + 0.35·x
∴ F(4) = 1.25 + 0.35 × 4 = 2.65
Therefore, the cost of making 4,000 bicycles = 2.65 × $100,000 = $265,000
The slope of the cost function, F(x) = 1.25 + 0.35·x, is given by the coefficient of 'x' which is 0.35
The average slope of the graph of the profit function is ((3.5 - 0)/(4 - 0)) = 0.875
The slope of the cost function is less than the average slope of the graph of the profit function taken from the origin to the maximum point of the graph
C. When the company produces 5,500 bicycles, x = 5.5, we have;
F(5.5) = 1.25 + 0.35 × 5.5 = 3.175
The cost is 3.75 × $100,000 = $375,000 and the profit from te graph is $300,000
Therefore, the cost of making the 5,500 bicycles is more than the profit made in sales
The company should plan on making fewer than 4,000 bicycles, to reduce cost of producing more bicycles and to increase profit per unit of bicycle sold

At the end of a snow storm, Michael saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of snow on Michael's lawn, in inches, can be modeled by the equation S=-2t+20,S=−2t+20, where tt is the time, in hours, after the snow stopped falling. What is the xx-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
x-intercept equals 10
interpretation is that, after 10 hours, all of the snow will be melted
Step-by-step explanation:
The linear equation can be used to solve to get the value of unknown quantities. The x-intercept of the equation is 10 and its interpretation in the context of the problem is that it shows zero depth at t = 10.
What is a Linear equation?A linear equation is a equation that has degree as one.
To find the solution of n unknown quantities n number of equations with n number of variables are required.
The given equation for the depth of the snow is as below,
S = -2t + 20
Here, S is the depth at a time t.
Suppose S is on y-axis and t on the x-axis.
Since the x-intercept of an equation is found by Substituting y = 0.
Substitute S = 0 in the given equation to get,
0 = -2t + 20
=> 2t = 20
=> t = 10
It means at t = 20, the depth of snow will become zero.
Hence, the x-intercept for the given case is 10 and it shows zero depth of the snow.
