A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y= -2x^2 + 105x – 859
Answer:
519
Step-by-step explanation:
or 519.125
The maximum amount of profit the company can make, to the nearest dollar should be considered as the $519.
Calculation of the maximum amount of profitSince the amount of profit made expressed as [tex]y=-2x^2+105x-859[/tex]
Now
At maximum profit, dy/dx = 0
So,
dy/dx = -4x + 105
0 = -4x + 105
4x = 105
x = 105/4
x = 26.25
Now
[tex]y=-2x^2+105x-859\\\\y=-2(26.25)^2+105(26.25)-859[/tex]
y = - 1,378.125+2,756.25-859
y = 519.125
Hence the maximum amount of profit the company can make is $519.

A line that passes through the points whose coordinates are (1,1) and (5,7)
is dilated by scale factor of 3 and centered at the origin. The image of the line
a) is perpendicular to the original line
b) is parallel to the original line
c) passes through the origin
d) is the same line
Answer:
B
Step-by-step explanation:
The image that the line will produce would be:
b). is parallel to the original line.
Given that,
Coordinates = [tex](1,1) and (5,7)[/tex]
Scale factor [tex]= 3[/tex]
As we know,
Slope [tex]= \frac{y_{2} - y_{1} }{{x_{2} - x_{1}} }[/tex]
where;
[tex]y_{2} = 7[/tex]
[tex]y_{1} = 1[/tex]
[tex]x_{2} = 5[/tex]
[tex]x_{1} = 1[/tex]
By putting these values,
Slope [tex]= (7 - 1)/(5-1)[/tex]
[tex]= 6/4[/tex]
[tex]=[/tex] [tex]1.5[/tex]
∵The image of the line would be ║ to the original line.
Thus, option b is the correct answer.

Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4
Answer:
y =-5x + 7
Step-by-step explanation:
y = -5x + 4
Slope = -5
Parallel lines have same slope
Slope of the parallel line to this line = -5
(1 , 2)
y -y1 =m(x - x1)
y - 2 = -5(x - 1)
y -2 = -5x + 5
y = -5x + 5 + 2
y = -5x + 7

there are 72 boys and 90 girls on a math team for the next competition mr. Johnson would like to arrange all the students in equal rows with only girls or only boys in each row. What is the greatest number of students that can be in each row
in order to get an A Mark needs to get at least 90% of the 650 points possible in the class. How many points must he earn of the 150-point final if he averaged 92 points on each of the five 100-point test
Answer:
at least 125 points on the final
Step-by-step explanation:
90% of 650 = 585
He needs at least 585 points to get at least 90%
Since he averaged 92 on the first 5 tests, he already has 5(92) = 460 pts
That means he needs to get at least 585 - 460 = 125 pts on the final exam

Answer:
BC ≈ 5.44 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] , that is
cos27° = [tex]\frac{BC}{6.1}[/tex] ( multiply both sides by 6.1 )
6.1 × cos27° = BC , then
BC ≈ 5.44 m ( to 3 significant figures )

A community centre organises a raffle to raise money for charity
There is one prize to be won
Daniel buys 17 raffle tickets.
A total of 280 tickets were sold
What’s the probability that Daniel does not win the prize
Answer:
263 / 280
Step-by-step explanation:
Given that :
Number of tickets bought = required outcome = 17
Total number of raffle = total possible outcomes = 280
Probability = required outcome / Total possible outcomes
P(winning) = 17 / 280
P(not winning) = 1 - 17/ 280
= 263 / 280

a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?
Answer:
y = 1/2x + 4
Step-by-step explanation:
If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.
So solve for b: using y = mx + b
2 = 1/2(-4) + b
2 = -2 + b
4 = b
Put it all together
y = 1/2x + 4
