Find the zeroes of the quadratic polynomial given below. find the sum and products of the zeroes and verify relationship of terms in the polynomial.
2. P of x = x square _4x+3
Answers
• P(x) = x² - 4x +3
To find :• The zeroes of the quadratic polynomial .
• To verify the relationship .
Solution :•x² - 4x + 3 = 0
Split the middle term :
=> x² - 3x - x + 3 = 0
=> x ( x - 3) - 1 ( x - 3 ) = 0
=> (x - 1)( x - 3 ) = 0
• x - 1 = 0
=> x = 1 .
• x - 3 = 0
=> x = 3 .
Hence , the zeroes are 1 and 3 .
Now , verification :• x² - 4x +3 .
compare with ax² + bx + c we get ,
• a = 1 , b = -4 and c = 3 .
As we know that :
• Sum of Zeroes = -b/a
=> 1 + 3 = -(-4)/1
=> 4 = 4
LHS = RHS .
NOW ,
• Product of Zeroes = c/a
=> 1(3)= 3/1
=> 3 = 3
LHS = RHS .
Hence, Verified .
I hope it will help you.

The school decided to purchase a Pac Man Arcade Machine. Because it was a used machine, the school got a 40% discount from the $540 cost. How much did the school pay for the arcade machine after the discount?
Answers
Answer: The answer is 324.
Step-by-step explanation: This is because, since we got a 40% discount that means we are paying 60% of the original price. So, 60% of 540=324. Hope this helps! Have a great day! :>

11. Members of the student council are conducting a fundraiser by selling school
calendars. After selling 80 calendars, they had a loss of $360. After selling
200 calendars, they had a profit of $600. Write an equation that describes the
relation between y, the profit or loss, and x, the number of calendars sold. How
much profit did they make from selling each calendar? How much would they
have lost if they had sold no calendars?
Answers
Answer:
See my explanations below please :)
Step-by-step explanation:
4. y-1 = 3(x-2)
5. y+5= -2(x+3)
6. y+11 = (3/4)(x-4)
7. y = (-1/6)(x-4)
8. y+2 = (5/8)(x+3)
9. y-1 = (3/8)(x+5)
10. Because after simplifying them, the final equations are the same
11. so we have (80,-360) and (200, 600)
m = (600-(-360)) / (200-80) = 960 / 120 =8
=> y+360 = 8(x-80)
Profit selling each = the slope m = $8
Working backwards, when they sold 80 calendars they still have a loss of $360, so the original loss (when x=0) = 80*8 + 360 = 640 + 360 = $1,000

Line segment YV of rectangle YVWX measures 24 units. Rectangle Y V W X is shown. A diagonal is drawn from point X to point V. The lengths of sides Y V and X W are 24 units. The angle of V X W is 30 degrees, the angle of X W V is 90 degrees, and the angle of X V W is 60 degrees. What is the length of line segment YX? 8 units 8 StartRoot 3 EndRoot units 12 units 12 StartRoot 3 EndRoot units
Answers
Answer:
The correct answer would be 8 root symbol 3
Step-by-step explanation:
because i chose it and got it right
The length of the line segment YX is [tex]8\sqrt{3}[/tex] if the line XW is of 24 units.
What is a trigonometric function?It is a ratio of sides of a right angled triangle.
How to use Trigonometric functions?It can be seen that the diagonal is making a right angle triangle XWV so
we will use the trigonometric function to determine the value of WV which will then be equal to XY because it is a rectangle.
tan(30)=VW/XW
1/[tex]\sqrt{3}[/tex]=VW/24
VW=24/[tex]\sqrt{3}[/tex]
VW=8[tex]\sqrt{3}[/tex] UNITS by multiplying and divide by root 3.
Hence the length of the side XY =8 root 3 units.

9. Large postcards come in packages of 20. Small postcards come in packages of 25. A store buys 24 packages of large postcards and 18 packages of small postcards. Which statement is true? * 10 points The store bought a total of 930 postcards The store bought 30 more small postcards than large postcards The store bought a total of 932 postcards. The store bought 68 more large postcards than small postcards.
Answers
Answer: 930 packages.
Step-by-step explanation:
Large postcards come in packages of 20.
Small postcards come in packages of 25.
A store buys 24 packages of large postcards. The total packages will then be:
= 20 × 24 = 480
The store buys 18 packages of small postcards. The total package here will be:
= 18 × 25 = 450
Therefore, total packages bought will be:
= 480 + 450
= 930 packages

Ben exercises every 12 days and Isabel every 8 days. Ben and Isabel both exercised today. How many days will it be until they exercise on the same day again?
Answers
Answer:
24 days
Step-by-step explanation:
First, we need to determine the Lowest common multiplier(LCM) of both days.
Given that;
Ben exercise for 12 days ,
Isabel exercise for 8 days
Hence, the LCM of both days is
12 = 2 × 2 × 3
8 = 2 × 2 × 2
Therefore,
LCM = 2 × 2 × 2 × 3 = 24.
It will take both Ben and Isabel 24 days to exercise on the same day again

Terry is paid $6.05 for evrey box of fruit picked and a bonus of $26.89 if more than 18 boxes are packed in one day. How much does Terry earn if he picks 49 boxes of fruit in one day
Answers
Answer:
The total amount earned by Terry is $323.34
Step-by-step explanation:
amount paid to Terry for every box of fruit picked, A = $6.05
bonus of $26.89 when more than 18 boxes are picked.
Amount earned by Terry for picking 49 boxes is given by;
A = $6.05 x 49 = $296.45
bonus earned by Terry since he picked more than 18 boxes in a day = $26.89
The total amount earned by Terry is given by;
Total amount = $296.45 + $26.89
Total amount = $323.34
Therefore, the total amount earned by Terry is $323.34

72+2=−18x+27
(72+2)=−18x+27(Combine Like Terms)
74=−18x+27
Step 2: Flip the equation.
−18x+27=74
Step 3: Subtract 27 from both sides.
−18x+27−27=74−27

Use the scenario to answer question 5-7 : Tonya is a Lyft driver and she charges a base fee of $3.50 to begin a drive. She then charges $0.50 per mile. Sandra needs a ride to the convention center but she has to pick up a friend along the way so she determines it is at least 15 miles to get there, but less than 20 miles. Write the domain for this scenario.
Answers
Step-by-step explanation:
We are expected to solve for the range of cost that Sandra will pay to Tonya
firstly, the model for Tonya's charge is
y=3.5+0.5x
For 15 miles
y=3.5+0.5(15)
y=3.5+7.5
y= $11
For 20 miles
y=3.5+0.5(20)
y=3.5+10
y= $13.5
Hence the domain is y=3.5+0.5x 11<=y<=13.5

PLSSSSSSSS HELP! How do I find the domain AND range in the same graph??
Answers
Answer:
Step-by-step explanation:
Let's start with definitions.
Domain: Indicates the values that x can be, has a certain set
Range: Indicates the values that y can be, has a certain set
To find the domain of a graph, we want to see where all the x values fit. In the graph below's case, the domain would be -3<x≤1
To find the range, we need to see where all the y values fit. In the graph below's case, the range would be -4≤y<0.
Notice how some of them are < instead of ≤. This is because they have an open circle. When a point has an open circle, it means that point can't be included in the equation, hence the < instead of ≤

Hugh made a recipe that yields 5 and 1 over 4 cups. If each serving is 1 over 2 cup, which expression will help Hugh determine the number of servings his recipe will yield?
Answers
Answer:
10 1/2 servings
Step-by-step explanation:
Hugh made a recipe that yields 5 and 1 over 4 cups.
Recipe = 5 1/4 cups = 21/4 cups
1 serving = 1/2 cup
The number of serving that Hugh's recipe would generate =
1/2 cup =>1 serving
21/4 cups => x
Cross Multiply
x = 21/4 / 1/2
= 21/4 ÷ 1/2
= 21/4 × 2/1
= 21/2
= 10 1/2 servings
The number of servings his recipe will yield is 10 1/2 servings
