Final answer:
The discriminant of a quadratic equation informs us about the nature of its roots. By calculating the discriminant for each given equation, we categorize them accordingly: equations with discriminant greater than zero have two distinct real roots, equal to zero have one repeated real root, and less than zero have two complex roots.
Explanation:
The discriminant of a quadratic equation ax² + bx + c = 0 is given by the expression b² - 4ac. The value of the discriminant determines the nature of the roots of the equation. To find the type of roots for each given equation:
x² − 4x + 2: The discriminant is (-4)² - 4(1)(2) = 16 - 8 = 8, which is greater than zero, so this equation has two distinct real roots.
5x² − 2x + 3: The discriminant is (-2)² - 4(5)(3) = 4 - 60 = -56, which is less than zero, indicating two complex roots.
2x² + x − 6: The discriminant is (1)² - 4(2)(-6) = 1 + 48 = 49, also greater than zero, leading to two distinct real roots.
13x² − 4 = 0 has a discriminant equivalent to that for x² − 4/13 = 0, which is 0² - 4(1)(-4/13) = 16/13, which is greater than zero, so this equation will have two distinct real roots.
x² − 6x + 9: The discriminant is (-6)² - 4(1)(9) = 36 - 36 = 0, indicating one repeated root.
x² − 8x + 16: The discriminant is (-8)² - 4(1)(16) = 64 - 64 = 0, which means this equation has one repeated root.
4x² + 11 = 0 has a discriminant equivalent to that for x² + 11/4 = 0, which is 0² - 4(1)(11/4) = -11, less than zero, thus resulting in two complex roots.
Through the method of using the discriminant, we can determine the types of roots each quadratic equation will have.

Answers
For this case we have that by definition, the point-slope equation of a line is given by:
[tex]y-y_ {0} = m (x-x_ {0})[/tex]
We have the following points:
[tex](x_ {1}, y_ {1}) :( 2,6)\\(x_ {2}, y_ {2}) :( 4,0)\\m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0-6} {4-2} = \frac {-6} {2} = -3[/tex]
We chose a point:
[tex](x_ {0}, y_ {0}) :( 4,0)[/tex]
Substituting in the equation we have:
[tex]y-0 = -3 (x-4)\\y = -3 (x-4)[/tex]

The two angles below form a linear pair, and the expressions are measured in degrees. What is the measure of the smaller angle?
62°
74°
118°
148°
Answers
Answer:
The measure of the smaller angle is 62°
Step-by-step explanation:
we know that
If two angles form a linear pair, then their sum is equal to 180 degrees (supplementary angles)
so
(2x-30)°+(x-12)°=180°
Solve for x
3x=180°+42°
3x=222°
x=74°
The measure of the angles are
(2x-30)°=2(74)-30=118°
(x-12)°=74-12=62° -----> smaller angle

For a certain weekend, the weatherman predicts that it will rain with a 40% probability on Saturday and a 50% probability on Sunday. Assuming these probabilities are independent, what is the probability that it rains over the weekend (that is, on at least one of the days)? Express your answer as a percentage.
Answers
Answer:
70%
Step-by-step explanation:
The probability it rains on at least one of the days is:
P = P(Sat & not Sun) + P(Sun & not Sat) + P(Sat & Sun)
P = (0.40)(1−0.50) + (0.50)(1−0.40) + (0.40)(0.50)
P = 0.20 + 0.30 + 0.20
P = 0.70
Another way to look at it is 1 − the probability that it doesn't rain on either day.
P = 1 − P(not Sat & not Sun)
P = 1 − (1−0.40)(1−0.50)
P = 1 − 0.30
P = 0.70
There is a 70% probability that it will rain on at least one day.
The probability that it will rain on at least one day over the weekend is 70%, based on independent probabilities given for Saturday and Sunday.
Explanation:The subject of your question is probability, a branch of mathematics that studies randomness and the likelihood of events occurring. To calculate the probability that it will rain over the weekend, i.e., on at least one of the days (Saturday or Sunday), we first need to find the probability that it won't rain on either day.
The probability it doesn't rain on Saturday is 60% (100% - 40%), and the probability it doesn't rain on Sunday is 50% (100% - 50%). Since these events are independent, we multiply these probabilities to find the joint probability. Therefore, the probability it doesn't rain on either day is 30% (0.6 × 0.5 = 0.3).
Now, this is the case which we don’t want (no rain), so the case we want (that it rains at least one day) is the complementary event of this. Thus, we subtract this from the total probability, which is 1, yielding a 70% (1 - 0.3) probability that it will rain on at least one of the days over the weekend.

You buy some living room furniture. The coffee table costs $189.99, the loveseat costs $249.95, the sofa costs $493.68, and 2 chairs cost $98.75 each. Sales tax is 7.25%. How much is your total purchase? $1,032.37 $1,213.13 $1,107.22 $1,131.12
Answers
Add the totals of each item together:
189.99 + 249.95 + 493.68 + 98.75 + 98.75 = 1,131.12
Now multiply that by the tax rate as a decimal:
1131.12 x 0.0725 = 82.01
Now add that to the total of the items:
1,131.12 + 82.01 = $1,213.13 total
For this case we have that the total of the purchase is given by:
Coffee table: $ 189.99
Loveseat: $ 249.95
Sofa: $ 493.68
2 chairs: 2 * $ 98.75 = $ 197.5
Adding up we have: $ 1131.12
Now, we must find the tax amount:
$ 1131.12 ----------> 100%
x ------------------------> 7.25%
Where "x" represents the value of the tax:
[tex]x = \frac {7.25 * 1131.12} {100}\\x = 82.0062[/tex]
Finally, the amount to be paid is:

You hike uphill at a rate of 200 feet per minute. Your friend hikes downhill on a same trail at a rate of 250 feet per minute. How long will it be until you meet?
Answers
Answer:
After x/450 minutes
Step-by-step explanation:
The speed uphill is 200 ft/min
The speed down hill is 250 ft/min
Lets take the hiking distance top to down hill is x ft
Remember speed=distance/time
Relative speed =200+250=450ft/min
Time to meet=distance/relative speed
Time to meet=x/450 min
Final answer:
To find out how long it will take until you meet, we need to determine the distances each hiker covers and then divide it by their respective rates.
Explanation:
To find out how long it will take until you meet, we need to determine the distances each hiker covers and then divide it by their respective rates.
The first hiker covers a certain distance while hiking uphill, while the second hiker covers a certain distance while hiking downhill. When they meet, their combined distances will add up to the total distance of the trail.
Let's say it takes x minutes for you to meet. The first hiker covers a distance of 200x feet in x minutes, while the second hiker covers a distance of 250x feet in the same x minutes. When they meet, their combined distances will equal the length of the trail, so we can set up the equation: 200x + 250x = total distance. Solving for x will give us the time it takes for you to meet.
Study the following data set.

What is the interquartile range of the data set?
Enter your answer as a number, like this: 42
Answers
Answer:
8
Step-by-step explanation:
The question is on interquartile range which is the median of the upper half of the data minus the median of the lower half of data
First arrange the data in an increasing order;
8,15,9,18,9,17,22,10,11,9,13
8,9,9,9,10,11,13,15,17,18,22
Find the median, which is the center value in the data set
8,9,9,9,10,11,13,15,17,18,22⇒the median is 11
Place brackets around the numbers above and below the median
(8,9,9,9,10)11 (13,15,17,18,22)
Find the median in the lower half of the data,Q1
(8,9,9,9,10) ⇒median is 9=Q1
Find the median in the upper half of the data,Q3
(13,15,17,18,22)⇒median is 17=Q3
Subtract Q1 from Q3 to get the interquartile range
Q3=17, and Q1=9
Q3-Q1=17-9=8

Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the graph we have two points (-5, -1) and (-2, -3).
Look at the picture.
Calculate the slope:
[tex]m=\dfrac{-3-(-1)}{-2-(-5)}=\dfrac{-2}{3}=-\dfrac{2}{3}[/tex]
Put it to the equation in slope-intercept form:
[tex]y=-\dfrac{2}{3}x+b[/tex]
We can't read the y-intercept from the graph. Therefore put the coordinates of the point (-5, -1) to the equation and calculate b:
[tex]-1=-\dfrac{2}{3}(-5)+b[/tex]
[tex]-1=\dfrac{10}{3}+b[/tex] subtract 10/3 from both sides
[tex]-\dfrac{3}{3}-\dfrac{10}{3}=b\to b=-\dfrac{13}{3}[/tex]
Finally:
[tex]y=-\dfrac{2}{3}x-\dfrac{13}{3}[/tex]

Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use any ordered pair from the given table of values
Using x = 1, y = - 9, then
k = [tex]\frac{y}{x}[/tex] = [tex]\frac{-9}{1}[/tex] = - 9

Point M is the midpoint of AB if the coordinates of A are (-3,6) and the coordinates of M are (-5,2) what are the coordinates of B ?
Please answer #5
Answers
Answer:
The coordinates of point B are (-7 , -2)
Step-by-step explanation:
* Lets explain how to solve the problem
- The mid-point (x , y) of the line whose endpoints are (x1 , y1) and
(x2 , y2) is [tex]x=\frac{x_{1}+x_{2}}{2},y=\frac{y_{1}+y_{2}}{2}[/tex]
∵ M is the midpoint of AB
∵ The coordinates of point A are (-3 , 6)
∵ The coordinates of point M are (-5 , 2)
- Let the coordinates of point A are (x1 , y1) , The coordinates of
point B are (x2 , y2) and The coordinates of point M are (x , y)
∴ x = -5 , x1 = -3 and y = 2 , y1 = 6
- Lets use the rule of the mid point to find x2 , y2
∵ [tex]-5=\frac{-3+x_{2}}{2}[/tex] ⇒ multiply both sides by 2
∴ [tex]-10=-3+x_{2}[/tex] ⇒ add 3 to both sides
∴ -7 = x2
∵ [tex]2=\frac{6+y_{2}}{2}[/tex] ⇒ multiply both sides by 2
∴ [tex]4=6+y_{2}[/tex] ⇒ subtract 6 from both sides
∴ -2 = y2
∵ The coordinates of point B are (x2 , y2)
∴ The coordinates of point B are (-7 , -2)

So, ratio of the number of votes that were not for mayor Jackson to the total number of votes is 3:7
Answer:
3 : 7
Step-by-step explanation:
It is given that,
In an election 32,000 people voted for Mayor Jackson
A total of 56,000 people voted in the election.
To find the ratio
Total number of people voted = 56000
Number of people voted for Mayor Jackson = 32000
Number of votes that were not for mayor Jackson = 56000 - 32000 = 24000
The ratio of the number of votes that were not for mayor Jackson to the total number of votes = 24000 : 56000
= 3 : 7

If you treat the number as x, then [tex]\frac{1}{2}x=x+5\to-5=\frac{1}{2}x\to-10=x[/tex].
Solve for x. x2 + 7x + 10 = 0 A. -2, -5 B. -2, 5 C. 2, -5 D. 2, 5
Answers
Answer:
A. -2, -5
Step-by-step explanation:
x^2 + 7x + 10 = 0
Factor the equation
What 2 numbers multiply to 10 and add to 7
2*5 =10
2+5 = 7
(x+2) (x+5)=0
Using the zero product property
x+2 =0 x+5 =0
x=-2 x = -5
Fencing costs $3.25 per foot. A certain
yard has a width of 60 feet and length of
80 feet How much is the cost to fence?
Answers
Answer:
910$
Step-by-step explanation:
It's easiest if we just add the width and length together to start which would be 2 sides of the fence so we multiply by 2 to complete the whole perimeter.
80+60 = 140 x 2 = 280
Now you need to multiply 280 by 3.25 because that is what it will cost in the end since the 280 is all of the feet together and the 3.25 is each foot's price.
3.25 x 280 = 910
910$
Which of the following statements justifies why the triangle shown below is
not a right triangle?
Answers
Answer:
A) 6^2 + 11^2 is not equal to 15^2
Step-by-step explanation:
To find out if a right triangle is a right triangle you have to use the Pythagorean Theorem, like it is used in A.
6^2 + 11^2 = 15^2
36 + 121 = 225
157 does not equal 225
So this is not a right triangle
Answer:
Option A
Step-by-step explanation:
Given in the picture is a triangle ABC with three sides given as 6,11 and 15
By the picture itself we can say that the largest angle is obtuse and hence the triangle is not right angled.
Using the converse of Pythagorean theorem that in a right triangle sides square add upto square of hypotenuse let us check whether this applies to this triangle.
Small sides are 6 and 11
Squaring and adding gives
[tex]6^2+11^2 = 187[/tex]
Large side = 11 and square is
[tex]15^2 =225 > 121[/tex]
Hence this is not a right triangle but obtuse
So option A is right
