What is the Graph function?The graph of a function f is the set of all points inside the aircraft of the shape (x, f(x)). We can also define the graph of f to be the graph of the equation y = f(x). So, the graph of a character is a unique case of the graph of an equation.
How does Graph function?For graphing functions, we need to plot its asymptotes, its x and y-intercepts, holes, and some factors on it by means of building a desk of values. Then simply join the factor by not touching the asymptotes and maintaining a observation of the area and range of the characteristic.

Every person has blood type O, A, B, or AB. A random group of people are blood-typed, and the results are shown in the table. A 2-column table with 4 rows is shown. The first column is labeled Blood Type with entries O, A, B, AB. The second column is labeled Number of People with entries 22, 20, 6, 2. Use the table to determine the following probabilities. The probability that a randomly chosen person from this group has type B is . The probability that a randomly chosen person from this group has type AB is . The probability that a randomly chosen person from this group has type B or type AB blood is .
Answer:
1 -- 3/25
2 -- 1/25
3 -- 4/24
Step-by-step explanation:
To find the probability of a randomly selected person being in any category, divide the amount of people in that category by the total amount of people.
We can find the total amount of people by adding the amount of people with each blood type.
Total = O + A + B + AB = 22 + 20 + 6 + 2 = 50
There are 50 total people in this group. Now we can find the probability of randomly selecting a person from each category.
Probability of type B
There are 6 people with type B blood. The probability of randomly selecting a person from this group is 6/50, or 3/25.
Probability of type AB
There are 2 people with type AB blood. The probability of randomly selecting a person from this group is 2/50, or 1/25.
Probability of type B or AB
We need to find the amount of people who are in either group. There are 6 people with type B blood and 2 people with type AB blood, so 8 people satisfy this criteria. The probability of randomly selecting a person with type B or AB blood is 8/50, or 4/25.

The length of a rectangle is 1 m more than twice the width, and the area of the rectangle is 45 m . Find the dimensions of the rectangle.
The length and width of the rectangle is 10 m and 4.5 m respectively.
Step-by-step explanation:
Given,
The length of a rectangle is 1 m more than twice the width.
Area of the rectangle = 45 sq m
To find the length and width of the rectangle.
Formula
If the length and width of a rectangle be l and b respectively, the area will be lb.
Let, the width (b) be = x and
Length (l) = 2x+1
According to the problem,
(2x+1)x = 45
or, [tex]2x^{2} +x = 45[/tex]
or, [tex]2x^{2}+x-45 = 0[/tex]
or, [tex]2x^{2}+(10-9)x-45 = 0[/tex]
or, [tex]2x^{2}+10x-9x-45 = 0[/tex]
or, 2x(x+5)-9(x+5) = 0
or, (2x-9)(x+5) =
Hence,
2x-9 = 0 and x+5 = 0
or, x = [tex]\frac{9}{2}[/tex] and x= -5
We will take x = [tex]\frac{9}{2}[/tex] as the value of length cannot be negative.
So,
Width = 4.5 m and Length = 2×4.5+1 = 10 m
The area of a rectangle is determined by the product of its length and width. In this rectangle, the width (W) is found to be 5 meters by solving the given equation. The length, being 1 meter more than twice the width, is 11 meters.
Explanation:To solve this problem, you can use the formula for the area of a rectangle, which is Area = length × width. You know from the problem that the area of the rectangle is 45 square meters, and the length (L) is 1 meter more than twice the width (W).
You can thus express the length in terms of the width: L = 2W + 1. Substituting this into the formula for the area gives you: 45 = W × (2W + 1).
Solving this equation involves expanding the right side: 45 = 2W² + W, arranging the equation to set the right side to zero: 2W² + W - 45 = 0
By factoring or using the quadratic equation, you find that the roots of the equation (the possible values for W) are 5 and -4.5. Since a negative width doesn't make sense in this context, you discard -4.5, and your width is thus 5 meters.
The length is then 2W + 1 = 2(5) + 1 = 11 meters. So, the dimensions of the rectangle are 5 meters by 11 meters.

Find the volume of a prism. The area of the pentagonal base is (124/tan36°)m² . It’s height is 13 m. If necessary, round your answer to the nearest hundredth.
The volume of the prism is about ____ m ³
The volume of the prism with a pentagonal base area of ([tex]\frac{124}{\tan36^\circ}[/tex])m² and height of 13 m is approximately 2218.73 m³ when rounded to the nearest hundredth.
The volume of a prism is calculated by multiplying the area of the base by the height of the prism. For a prism with a pentagonal base, if the area of the base is ([tex]\frac{124}{\tan36^\circ}[/tex])m² and the prism's height is 13 m, then the volume V is found by the following calculation:
V = area of base × height
V = ([tex]\frac{124}{\tan36^\circ}[/tex]) × 13
First, calculate the numerical value for tan36°:
tan36° ≈ 0.7265
Then plug this value into the formula:
V = (124÷0.7265) × 13
V ≈ 2218.73 m³
The volume of the prism is therefore approximately 2218.73 m³, rounded to the nearest hundredth.

Asher built two bookends and wants to paint them. How much paint will he need to cover the surface of both bookends? 468 cm2 576 cm2 936 cm2 1,044 cm2
Asher will need c. 936 cm² of paint to cover both the bookends.
Step-by-step explanation:
Step 1:
To determine the amount of paint needed, we determine the surface area of the triangular prisms.
To calculate the triangular prism's surface area, we calculate the areas of all the 5 sides. We divide the prism into 2 triangles and 3 rectangles, find the areas individually and then sum them all up in order to determine the area of the entire triangular prism.
Step 2:
There are two triangles with base lengths of 9 cm and heights of 12 cm. A triangle's area is half the product of the base length and its height.
Area of 1 triangle = [tex]\frac{1}{2} (9)(12) = 54[/tex] cm².
Area of both triangles = 2× Area of 1 triangle [tex]= 2(54)[/tex] = 108 cm².
Step 3:
There are three rectangles with a common length of 10 cm but there are three different widths. Any rectangle's area is calculated by multiplying the rectangle's length with its width.
Area of a rectangle with width 15 cm [tex]= (10)(15) = 150[/tex] cm².
Area of a rectangle with width 9 cm [tex]= (10)(9) = 90[/tex] cm².
Area of a rectangle with width 12 cm [tex]= (10)(12) = 120[/tex] cm².
Step 4:
The area of the entire triangular prism = Area of 2 triangles + Area of all the 3 rectangles = [tex]108+150+90+120 = 468[/tex] cm².
This is the surface area of 1 bookend. As both the bookends are similar.
The surface area of 2 bookends [tex]= 2(468) = 936[/tex] cm².
Asher will need 936 cm² of paint to cover both the bookends.

Jamal performed an experiment flipping a coin. He did 10 trials and then his arm got tired. He recorded his results in the table. Based on the experimental probability, Jamal predicted that the number of times the coin lands heads up will always be greater than the number of times it lands tails up. What is the error in his prediction?
He should have performed fewer trials before comparing them to the theoretical probability.
He did not need to perform the experiment to compare theoretical and experimental probabilities.
He should have subtracted the theoretical probability from the experimental probability.
He did not perform enough trials to compare the theoretical and experimental probabilities.

.4x=.5x-30 solve for x
Answer:
x=300
Step-by-step explanation:
Multiply both sides by 10
0.4x·10=0.5x·10-30·10
Refine
4x=5x-300
Subtract 5x from both sides
4x-5x=5x-300-5x
Simplify
-x=-300
Divided both sides by -1
-x/-1=--300/-1
Simplify this and you will get x=300

Answer:
[tex]\theta=128.5^{\circ}[/tex]
Step-by-step explanation:
The given angle measure is
[tex]\theta=\dfrac{257\pi}{360}[/tex]
We need to convert the radian measure to degree.
To convert radian to degree, multiply the given measure by [tex]\frac{180^{\circ}}{\pi}[/tex].
[tex]\theta=\dfrac{257\pi}{360}\times \dfrac{180^{\circ}}{\pi}[/tex]

Find the value of c that makes the expression a perfect square trinomial.
x2 – 15x + c
A) 225/4
B) 225/2
C) 30
D) 225
The value of c that makes the expression x² − 15x + c a perfect square trinomial is obtained by squaring half the coefficient of x, which in this case is 225/4. Therefore option A is the correct answer.
To find the value of c that makes the expression x² − 15x + c a perfect square trinomial, we need to find a value for c such that the trinomial can be expressed as the square of a binomial.
This binomial will have the form (x - h)², where h is half the coefficient of the x term in the original trinomial.
In this case, the coefficient of x is -15.
Half of -15 is -15/2.
Squaring this value will give us c. Thus, (-15/2)² equals 225/4.
The value of c that makes the expression a perfect square trinomial is 225/4.
