Answer:
A
Step-by-step explanation:
A function is a relationship between inputs where each input is related to exactly one output.
A function can be one-to-one and many-to-one but can not be one-to-many.
The relation that is a function is
(1, 1), (2, 2), (3, 3), (4, 4). (5, 8). C. ( 2, 7),
Option B is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
A function can be one-to-one and many-to-one but can not be one-to-many.
A. (1, 0), (3.0), (1.1), (3, 1) (1.3)
This is not a function because we have one-to-many.
(1, 0) and (1, 1) are one-to-many.
B. (1, 1), (2, 2), (3, 3), (4, 4). (5, 8).
This is a function because it satisfies the function.
The given relation are one-to-one.
C. ( 2, 7), (6,5), (4.4), (3, 3), (2, 1)
This is not a function because we have one-to-many.
(2, 7) and (2, 1) are one-to-many relations.
D. (9. -3), (19, 3) (4, -2), (4, 2), (0, 0)
This is not a function because we have one-to-many relations.
(4, -2) and (4, 2) are one-to-many relations.
Thus,
The relation that is a function is
(1, 1), (2, 2), (3, 3), (4, 4). (5, 8). C. ( 2, 7),
Option B is the correct answer.

This is a right triangle trigonometry question.
Use half of the diameter to form the base of the triangle (19.3 ft) with a height 0f 13.
Use Inverse Tangent function to find the angle of repose

Market researchers were interested in the relationship between the price of bobbleheads and the demand of bobbleheads. Information was collected from a survey and used to obtain the regression equation ŷ = –0.227x + 50.455, where x represents the price of bobbleheads (measured in dollars) and ŷ is the predicted demand of bobbleheads (in units). What is the predicted demand of a bobblehead that has price of $6.00?
–1.362 units
49.093 units
51.817 units
195.837 units
Answer:
49.093
Step-by-step explanation:
Given the regression equation :
ŷ = –0.227x + 50.455
x represents the price of bobbleheads (measured in dollars)
ŷ is the predicted demand of bobbleheads (in units).
Preductwd demand ; when x = 6
ŷ = –0.227(6)+ 50.455

I need help. So it says to find the shaded area, and I'm not really good a things like this
Answer:
86 cm²
Step-by-step explanation:
1) Calculate the area of the square
[tex]A=lw\\A=20*20\\A=400[/tex]
Therefore, the area of the square is 400 cm².
2) Calculate the area of the circle
[tex]A=\pi r^2\\[/tex]
[tex]\pi[/tex] we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
[tex]A=3.14*10^2\\A=3.14*100\\A=314[/tex]
Therefore, the area of the circle is 314 cm².
3) Subtract the area of the circle from the area of the square
[tex]A=400-314\\A=86[/tex]
Therefore, the area of the shaded region is 86 cm².
I hope this helps!
Step-by-step explanation:
Given,
One side of the square = 20 cm
Therefore, Area of the square = side × side
= 20 cm × 20 cm
[tex] \: \: \: \: \: \: \: \: = 400 {cm}^{2} [/tex]
Also, known that
One side of the square = Diameter of the circle = 20 cm
So, radius of the circle = 20/2 cm = 10 cm
Therefore, area of the square
[tex] \: \: \: \: \: \ \: \: \: \: = \pi{r}^{2} [/tex]
[tex] = 3.14 \times {(10cm)}^{2} [/tex]
[tex] = 3.14 \times 100 {cm}^{2} [/tex]
[tex] = 314 {cm}^{2} [/tex]
Hence, area of the shaded region is
= Area of the square. - Area of the circle
[tex] = 400 {cm}^{2} - 314 {cm}^{2} [/tex]
[tex] = 86 {cm}^{2} (ans)[/tex]

Answer:

Step-by-step explanation:
How do you solve for an area of a circle?
Answer:
Identify the radius of a circle. The radius is the length from the center of a circle to the edge of the circle. You can measure this in any direction and the radius will be the same. The radius is also one half of the diameter of a circle. The diameter is the line segment that passes through the center and connects opposite sides of the circle.[1]
The radius will generally be provided to you. It can be difficult to measure to the exact center of a circle, unless the center is already marked for you on a circle drawn on paper.
For this example, assume that you are told that the radius of a given circle is 6 cm.
well the formula for the area of a circle is A =[tex]\pi r^2[/tex]
r is for the radius
which is half the size or number of the diameter
so ex. lets say that the diameter of a circle is 10, so that makes the radius 5
A = [tex]\pi[/tex] [tex]5^2[/tex]
A = [tex]\pi * 25[/tex]
A = 78.54
Ta -Da!!
Note: sometimes is the test ask you to replace [tex]\pi[/tex] for 3.14, it would still work

b) Area of the circle = 254.34 in²
Step-by-step explanation:
Mr. Bernard needs to order boxes for his 18-inch diameter "Super Pizza."
Note that:
Pizza is Circular in shape
a) What is the approximate circumference of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the circumference of a circle when given that diameter = πD
Where D = Diameter of the circle = 18 in
π = 3.14
Hence,
Circumference of the circle = 3.14 × 18 in
= 56.52 in
b) What is the approximate area of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the area of a circle = πr²
Radius = Diameter/2
Diameter = 18 in
Radius = 18 in/2 = 9 in
The area of the circle = 3.14 × 9²
= 254.34 in²

Chloe compares the growth of plant species A and B. Part A What do the box plots tell you about the growth of a typical plant of each species? Choose the correct response. Plant B typically grows 1 cm taller than Plant A, since the range for Plant B is 1 cm greater. Plant B typically grows 1 cm taller than Plant A, since the IQR for Plant B is 1 cm greater. Plant A typically grows 1 cm taller than Plant B, since the median for Plant A is 1 cm greater. Plant A typically grows 1 cm taller than Plant B, since the mean for Plant A is 1 cm greater.
Answer:
Type A Type B
Median 52 grams 52 grams
Lower Quartile 49 grams 51 grams
Upper Quartile 57 grams 54 grams
Range 14 grams 8 grams
Interquartile Range 8 grams 3 grams
From this table we can see that both types of tomato have the same average mass because their medians are the same.
Comparing the medians and interquartile ranges shows that there is far more variation in the masses of the type A tomatoes, which means that the masses of type B are more consistent than those of type A.
However, comparing the two box and whisker plots, and the upper quartiles, shows that type A tomatoes will generally have a larger mass than those of type B.
Nevertheless, there will be some type A tomatoes that are lighter than any of type B.
Taking all this together, the gardener would be best advised to plant type A tomatoes in future as he is likely to get a better yield from them than from type B.
