Step-by-step explanation:
The maximum amount of profit the company can make is $543
Let y represent the amount of profit and x represent the selling price.
The relationship between x and y is:
y = -4x² + 141x – 703
The maximum profit is at dy/dx = 0, hence:
dy/dx = -8x + 141
-8x + 141 = 0
8x = 141
x = 17.625
The maximum profit is:
y = -4(17.625)² + 141(17.625) – 703 = 543
The maximum amount of profit the company can make is $543

Answer:
left edge should measure 1 cm and bottom should measure 2 cm because it has to be scaled
Step-by-step explanation:
1 cm = 3 ft
left side is 2cm wants it to be 3 feet and 1cm = 3 feet so you make it from to cm to 1 cm aka 3 feet and the bottom side 2 cm so that its scaled :)

Which equation represents a line which is perpendicular to the line y = 4/3x -7
A)3x + 4y = 8
B)4x – 3y = 24
C)4x + 3y = -6
D)4y - 3x = 12
Answer:
A)3x + 4y = 8
Step-by-step explanation:
Given expression;
y = [tex]\frac{4}{3} x[/tex] - 7
A line perpendicular to this will have negative inverse slope;
the slope of the given line = [tex]\frac{4}{3}[/tex]
perpendicular line = [tex]-\frac{3}{4}[/tex]
Now;
the equation of the line is;
y = [tex]-\frac{3}{4}[/tex] x - 7
multiply through by 4
4y = -3x - 28
4y + 3x = -28

Van purchased a DVD player on sale. The original selling price was $154.30. The sale price was $132.17. What is the first step in finding the percent markdown? Find the percent markdown.
Answer:
Percentage decrease= 14.34%
Step-by-step explanation:
Giving the following information:
The original selling price was $154.30. The sale price was $132.17.
To calculate the percentage decrease, we need to use the following formula:
Percentage decrease= [(P0 - P1)/P0]*100
Percentage decrease= [(154.3- 132.17)/154.3]*100
Percentage decrease= 14.34%

Ian wants to run 4 1/2 miles to get ready for his upcoming race. He has set up 3 markers the same distance apart to show how far he has run. How far apart are the markers?
Answer:
1 1/2
Step-by-step explanation:
Given that:
Total miles to run = 4 1/2 miles
Number of same distance markers set = 3
The diatances between each marker :
Total distance / number of markers
4 1/2 ÷ 3
9 /2 ÷ 3
9 / 2 * 1 /3
= 9 /6
= 3/2 = 1 1/2
Hence, the distance between each marker = 1 1/2

In American football, the ball is punted by dropping and kicking it before it hits the ground. The height h(t) of the football above the ground in meters t seconds after being punted is affected by gravity and by the punter's kick, and can be represented as the difference of two functions: a(t)=1.4t2, which specifies the effect of gravity on the height of the ball, and v(t)=12.1t+2.5, which specifies the effect of the punt on the ball. With these two functions, h(t)=v(t)-a(t), how high above the ground was the ball when it was punted?
Answer:
h = 8.845 m
Step-by-step explanation:
The height h(t) of the football above the ground in meters t seconds after being punted is affected by gravity and by the punters kick, and can be represented as the difference of two functions:
[tex]a(t)=1.4t^2\\\\v(t)=12.1t+2.5[/tex]
We need to find h(t) such that, h(t)=v(t)-a(t)
So,
[tex]h(t)=12.1t+2.5-1.4t^2\\\\h(t)=-1.4t^2+12.1t+2.5[/tex]
It is a quadratic equation. When we solve it we get :
[tex]h(t)=8.845\ m, -0.2\ m[/tex]
Neglecting negative value,
h(t) = 8.845 m
So, the ball was at a height of 8.845 m when it was punted.

Write an equation of the line that passes through (2, – 4) a
and
(0, – 4).
y =
Answer:
y=-4
Step-by-step explanation:
first,
you find the slope by doing
y2-y1/x2-x1 and getting 0.
then plug into point slope form,
y-y1=m(x-x1)
y-(-4)=0(x-2)
y+4=0
y=-4
write and equation in slope intercept form (y=mx+b) for the graph below
Answer:
y=1/3x+0 or y=1/3x
Step-by-step explanation:
find the slope by taking two points and putting them in
y2 - y1/x2 - x1
so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3
then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)
y - 2 = 1/3(x-6)
when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given

Nolan says the relationship in the table is not proportional because the point (0, 0) does not appear in the table.
Which is the best way to explain to Nolan why he is incorrect?
A. A graph made from the table will be increasing, so it is proportional.
B. Not all proportional relationships contain (0, 0), so it could be proportional.
C. The points on the graph will have even y-coordinates, so it is proportional.
D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.
Answer: D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.
Step-by-step explanation:
The table is not included but this should be the correct answer.
Linear relationships which are proportional will have to pass through the origin which is (0,0). This does not mean that on the table, the points (0,0) have to be there.
Even if it does not explicitly appear in the table, so long as the line passes the origin, it is to be considered a proportional relationship. The (0,0) might not appear on the table because only a few points the line passed through were listed but if when the line is plotted, the line goes through (0,0), it is proportional.

Answer:
m∠N = 41°
Step-by-step explanation:
Here,
In △MNO, m∠M = (6x + 1°) ...(1)
m∠N = (3x - 10°) ...(2)
m∠0 = (x + 19°) ...(3)
Here, We know that the sum of all angles of a triangle is 180°
Then,
(6x + 1°) + (3x - 10°) + (x + 19°) = 180°
6x + 1° + 3x - 10° + x + 19° = 180°
6x + 3x + x + 1° - 10° + 19° = 180°
10x + 10° = 180°
10x = 180° - 10°
10x = 170°
x = 170° ÷ 10°
x = 17°
Now, put the value of x in (1), (2) and (3)
m∠M = (6x + 1°)
= (6(17) + 1°)
= (102° + 1°)
m∠M = 103°
m∠N = (3x - 10°)
= (3(17) - 10°)
= (51° - 10°)
m∠N = 41°
m∠0 = (x + 19°)
= (17 + 19°)
m∠0 = 36°
Thus, The m∠N = 41°
FOR VERIFICATION ONLY:(6x + 1°) + (3x - 10°) + (x + 19°) = 180°
(6(17) + 1°) + (3(17) - 10°) + (17 + 19°) = 180°
103° + 41° + 36° = 180°
180° = 180°
Hence, L.H.S = R.H.S

Answer:
slope is 0
Step-by-step explanation:
Answer:There is no slope to this answer. The slope is undefined
Step-by-step explanation: This is because when you use the slope equation (rise over run) you get 1 over 0, because you rise but don't move on the x axis at all. Since you cannot divide by zero the answer is undefined. The slope would be zero if it was a horizontal line for example 0/1 slope.
