When finding slant asymptotes, do you prefer long division or synthetic division to find the equation of the line? Why?
Answer:
A slant (oblique) asymptote occurs when the polynomial in the numerator is a higher degree than the polynomial in the denominator. To find the slant asymptote you must divide the numerator by the denominator using either long division or synthetic division. why because You might find the wrong answer to the problem and You will Get every problem wrong unless You use the slant asym.

A gym teacher has a large canvas bag that contains 8 tennis balls, 2 volleyballs, 1 basketball, 3 baseballs, and 5 footballs. If you reach into the bag at random, what is the probability that you select a football?
A.5/18
B. 5/19
C. 5/14
D. 8/19
The total amount of balls there are is : 8 + 2 + 1 + 3 + 5 = 19 (balls)
There are 5 footballs in the bag, so the probability of you selecting a football is 5 : 19 = 5/19
There are 8 members of a basketball team . In their last game their mean points scored was 12 . Dom was their best player with 33 points . Dom thinks that if he hadn't played the mean points scored would be 10 . Is Dom right or wrong ? You must explain your answer .
The mean points of the team is the average points per game
Dom's claim is wrong
How to determine if Dom is rightThe number of players in the team is:
n = 8
The mean score per game is:
Mean = 12
The mean of a dataset is calculated as:
[tex]Mean = \frac{Total}n[/tex]
So, we have:
[tex]12= \frac{Total}8[/tex]
Multiply both sides by 8
[tex]Total = 96\\[/tex]
When Dom's point is removed, we have:
[tex]Points = 96 - 33[/tex]
[tex]Points = 63[/tex]
There are 7 players left.
So, the mean point is:
[tex]Mean = \frac{63}7[/tex]
[tex]Mean = 9[/tex]
The mean score is not 10.
Hence, Dom's claim is wrong

Which of the following functions best describes this graph.
50 POINTS!!
Answer:
D is your correct answer
Step-by-step explanation:
This is a quadratic equation which means that it has two roots which is your X-Intercepts. As seen on the graph, your X-intercepts are 3 and 5 which are your roots. Simple bring them over to the other side so you have (X-3) and (X-5)
You now multiply them into each other:
(X-5)×(X-3)=0
: X^2-8x+15
Answer:
D) y = x² - 8x + 15
Step-by-step explanation:
x-intercepts are at x = 3 and x = 5
⇒ y = (x - 3)(x - 5)
⇒ y = x² - 8x + 15

[tex]\bold{\huge{\underline{ Solution }}}[/tex]
Given :-We have given one irregular figure which is composed of semicircle and parallelogramTo Find :- We have to find the total area of the given irregular figure .Let's Begin :-We have,
Semicircle having diameter = 8 in.Therefore, R = 8/2 = 4 in.Parallelogram having base and height 10 in. and 6 in.We know that,
Area of semicircle
[tex]\bold{\pink{ = }}{\bold{\pink{\dfrac{1}{2}}}}{\bold{\pink{\pi{r^{2}}}}}[/tex]
Subsitute the required values,
[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{\dfrac{4^{2}}{2}}}}[/tex]
[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{\dfrac{16}{2}}}}[/tex]
[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{8}}}[/tex]
[tex]\sf{ = }{\sf{\dfrac{176}{7}}}[/tex]
[tex]\bold{ = 25.142\: in.^{2}}[/tex]
Now :-Area of parallelogram
[tex]\bold{\red{ = Base }}{\bold{\red{\times{ Height }}}}[/tex]
Subsitute the required values,
[tex]\sf{ = 10 }{\sf{\times{ 6 }}}[/tex]
[tex]\bold{ = 60 \:in.^{2}}[/tex]
Thus, The area of parallelogram is 60 in.
Therefore,Area of the given figure
= Area of semicircle + Area of parallelogram
Subsitute the required values,
[tex]\sf{ = 25.142 + 60 }[/tex]
[tex]\sf{ = 85.142\: in^{2}. }[/tex]
When round off to nearest Hundred
[tex]\bold{ = 85.1 in.^{2}}[/tex]
Hence, The area of the given figure is 85.1 inches² .
The area of the composite figure to the nearest hundredth is 85.12 inches squared.
What is area of a figure?The area can be defined as the space occupied by a flat shape or the surface of an object.
Therefore, the figure is a composite figure, it has a parallelogram and a semi circle.
area of the figure = area of parallelogram + area of semi circle
area of parallelogram = bh
where
b = baseh = heightb = 10 inches
h = 6 inches
area of parallelogram = 10 × 6 = 60 inches²
area of semi circle = πr² / 2
where
r = radiusTherefore,
r = 8 / 2 = 4 inches
area of semi circle = 3.14 × 4² / 2
area of semi circle = 3.14 × 16 / 2
area of semi circle = 50.24 / 2
area of semi circle = 25.12 inches²
area of the figure = 60 + 25.12 = 85.12 inches²

The equations below represent the total amount charged, y, by two different plumbers as a function of the number of hours worked, X
Plumber A: y = 20x + 60
Plumber B: y = 40%
The graphs of these functions cross at the point (3, 120). What does the point (3,120) signify?
Answer:
both plumbers charge $120 for 3 hours of work
Step-by-step explanation:
1) x=3 and x stands for hours.
2) 120=y and y stands for money charged
so the points (3, 120) show that the plumbers both charge 120 for 3 hrs.

Answer:
1. 130°
2. 65°
3. 158°
4. 135°
5. 135°
Step-by-step explanation:
Let x be the unknown angle
1. Congruent angles are marked with a dash
Sum of interior angles of a 5-sided polygon is 540°
⇒ x + 90 + 110 + 100 + 110 = 540
⇒ x = 130°
2. Congruent angles are marked with a dash
Sum of interior angles of a triangle is 180°
⇒ 2x + 50 = 180
⇒ x = 65°
3. Sum of interior angles of a 5-sided polygon is 540°
⇒ x + 76 + 90 + 90 + 126 = 540
⇒ x = 158°
4. Congruent angles are marked with a dash
Sum of interior angles of a 6-sided polygon is 720°
⇒ 4x + 90 + 90 = 720
⇒ x = 135°
5. Congruent angles are marked with a dash
Sum of interior angles of a 8-sided polygon is 1080°
⇒ 8x = 1080
⇒ x = 135°
Twice a number added to another number is 15. The sum of the two numbers is 11. Find the numbers
Answer:
4 and 7
Step-by-step explanation:
let's call the first number 'x' and the second number 'y'
so from the question we obtain two equations:
2x+y=15 ..... equation 1 and
x+y=11 .........equation 2
rearranging equation 2
y=11-x
now let's substitute it to equation 1
2x+11-x=15
x=15-11
x=4
now solving for y(let's take equation 2)
4+y=11
y=11-4
y=7

ANSWER:
x = -3
Step-by-step explanation:
55+54+x+74=180
109+x+74=180
183 + x = 180
x = -3
Answer:
Step-by-step explanation:
All triangles have 180 as the sum of the 3 interior angles.
x + 74 + 55 + 54 = 180 Combine
x + 183 = 180 Subtract 183 from both sides.
x = 180 - 183 Combine
x = - 3
You probably have been told that there is no such thing as a minus angle, and that's true. The angle isn't minus. Just x is. The size of the angle is
Angle size = 74 - 3 = 71
Now try adding them together
55 + 54 + 71 = 180 which is what it should come to

What is a scatter plot?A scatter plot can be defined as a graph which uses Cartesian coordinates (x-axis and y-axis) to display the values of two (2) variables, with the resulting points revealing any correlation between the data.
What is a trend line?A trend line refers to an statistical (analytical) tool that is used in conjunction with a scatter plot, so as to determine whether or not there's any correlation between a data.
For example, a scatterplot with an x-axis with its points ranging from twenty (20) to sixty (60) in increments of ten (10) while the y-axis has its points ranging from twenty (20) to forty (40) in increments of five (5) with a negative trend line through the middle of eight (8) points i.e above and below the trend line.
