Answer: 5
Step-by-step explanation: The dot in the middle of the circle is the center point of the circle. This means that it bisects every point from one edge to the other cutting through the middle. The two vertical red lines in the middle of the circle indicate they are the same measure. knowing this and that the angle interiors are 90 degrees, we can conclude that x is the same length as the 5 diagonal from it.
Answe is 5..
The (.) is the center of the circle..
The (|) mesns these lines are equal..
The angles also are right angles and equal..
Means the length ofvthis line also equals the other line = 5
Use the table of values to find the function's values.
If x=0, then f(0) =
If f(x) = 27, then x =
Answer:
If x=0, then f(0) = -15
If f(x) = 27, then x = 3
Step-by-step explanation:
Find where the x column on the table has a 0 and find the corresponding f(x) value which is -15.
Do then same for the other question but find where f(x) on the table is equal to 27 and find the corresponding x value which is 3
If x=0, then f(0) = -15
If f(x) = 27, then x = 3
Step-by-step explanation:We are given a table of values as follows:
x f(x)
-3 33
-2 17
0 -15
2 -7
3 27
This means that x is the independent variable and f(x) is the dependent variable corresponding to the variable x.
Hence, from the table of values we have:
If x=0, then f(0) = -15
If f(x) = 27, then x = 3

In spherical geometry lines are called _____
Answer:
the answer is: a great circle
In spherical geometry, lines are called geodesics, which are represented by great circles on the surface of a sphere. These circles are the spherical equivalents of straight lines in Euclidean geometry and highlight the unique properties of spherical geometry, such as the different rules for angles and parallel lines.
In spherical geometry, lines are referred to as geodesics. Unlike in Euclidean geometry where lines are the shortest distance between two points on a plane, in spherical geometry, geodesics are the shortest paths on the surface of a sphere and are represented by great circles. Great circles are the largest circles that can be drawn on a sphere, with their centers coinciding with the center of the sphere. This concept is crucial in areas such as cartography and navigation where the Earth's surface needs to be understood as a sphere rather than a flat plane.
For example, in creating a triangle on the Earth's surface with one corner at the north pole and the other two at the equator separated by 90 degrees of longitude, the sum of its interior angles exceeds 180 degrees. This defies a fundamental rule of Euclidean geometry, indicating the unique properties of spherical geometry where traditional parallel lines do not exist and the axioms of Euclidean geometry are not entirely applicable.
If you factor 4x^2-49y^2 what’s the answer
Answer:
(2x - 7y)(2x + 7y)
Step-by-step explanation:
4x^2-49y^2 is the difference of two squares: (2x)² - (7y)².

A hexagonal pyramid has a volume of 144 cubic millimeters and a height of 4 millimeters. What is the area of the base of pyramid
The answer is:
The area of the base of the pyramid is:
[tex]BaseArea=108mm^{2}[/tex]
Why?We are given the volume and the height of the hexagonal pyramid, so, to calculate the base of the area, we need to use the following formula:
[tex]Volume=\frac{1}{3}*BaseArea*Height[/tex]
So, we are given the following information:
[tex]Volume=144mm^{3}\\\\Height=4mm[/tex]
Then, substituting the given information and isolating the base area, we have:
[tex]Volume=\frac{1}{3}*BaseArea*Height[/tex]
[tex]144mm^{3} =\frac{1}{3}*BaseArea*4mm\\\\144mm^{3}*\frac{3}{4mm}=BaseArea\\\\BaseArea=108mm^{2}[/tex]
Hence, the area of the base of the hexagonal pyramid is equal to:
[tex]BaseArea=108mm^{2}[/tex]

A carousel is an amusement ride consisting of a rotating circular platform with seats for riders. The carousel at a local theme park has a diameter of 32 feet. Each ride lasts 3 minute mes and the speed of the carousel is 4.3 revolutions or minute what is the maximum distance riders travel in one full ride?
Answer:
1296.85 ft
Step-by-step explanation:
Answer:
The maximum distance riders travel in one full ride is:
1296.192 feet
Step-by-step explanation:
It is given that the diameter(d) of carousel is: 32 feet.
This means that the distance travelled in one revolution is equal to the circumference(C) of the circle.
We know that the circumference of circle is given by:
[tex]C=\pi\times d\\\\\\C=3.14\times 32\\\\\\C=100.48\ feet[/tex]
Also, Time of one full ride is: 3 minutes.
Speed of one full ride is: 4.3 revolutions per minute.
This means that the number of revolutions made is calculated as:
Number of revolution=Speed×Time
Number of revolution=4.3×3=12.9 revolutions.
Hence, total distance traveled in one full ride is:
Number of revolution made×Distance covered in one revolution
= 12.9×100.48
= 1296.192 feet

d
=
number of dollars
p
=
number of pounds
Drag each table and equation to the unit rate it matches.
Answer:
General equation of line : [tex]y = mx+c[/tex] --1
Where m is the slope or unit rate
Table 1)
p d
1 3
2 6
4 12
d = Number of dollars (i.e.y axis)
p = number of pound(i.e. x axis)
First find the slope
First calculate the slope of given points
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] ---A
[tex](x_1,y_1)=(1,3)[/tex]
[tex](x_2,y_2)=(2,6)[/tex]
Substitute values in A
[tex]m = \frac{6-3}{2-1}[/tex]
[tex]m = 3[/tex]
Thus the unit rate is 3 dollars per pound.
So, It matches the box 1 (Refer the attached figure)
Equation 1 : [tex]p=3d[/tex]
[tex]\frac{p}{3}=d[/tex]
Since p is the x coordinate and d is the y coordinate
On Comparing with 1
[tex]m = \frac{1}{3}[/tex]
Thus the unit rate is [tex]\frac{1}{3}[/tex] dollars per pound
So, It matches the box 2 (Refer the attached figure)
Equation 2 : [tex]\frac{1}{3}d=3p[/tex]
[tex]d=9p[/tex]
Since p is the x coordinate and d is the y coordinate
On Comparing with 1
[tex]m =9[/tex]
Thus the unit rate is 9 dollars per pound
So, It matches the box 3 (Refer the attached figure)
Table 2)
p d
1/9 1
1 9
2 18
d = Number of dollars (i.e.y axis)
p = number of pound(i.e. x axis)
[tex](x_1,y_1)=(\frac{1}{9},1)[/tex]
[tex](x_2,y_2)=(1,9)[/tex]
Substitute values in A
[tex]m = \frac{9-1}{1-\frac{1}{9}}[/tex]
[tex]m = \frac{8}{frac{8}{9}}[/tex]
[tex]m = 9[/tex]
Thus the unit rate is 9 dollars per pound
So, It matches the box 3 (Refer the attached figure)

What is the value of the positive zero of the function , f, defined by f(x) =x^2-121
Answer:
The positive zero is 11
Step-by-step explanation:
Given in the question an equation,
f(x) =x² - 121
We are asked to find the positive zero of f(x)
means x > 0 for which f(x) = 0
so,
x² - 121 = 0x² = 121
Take square root on both sides of the equation
√x² = √121
x = ±11
which means that x = 11 and x = -11
Since x > 0 so we will reject x =-11 and we will accept x = 11
Answer: 11
Step-by-step explanation:
You need to substitute [tex]f(x)=0[/tex] into the function given:
[tex]f(x) =x^2-121\\0 =x^2-121[/tex]
Now you need to solve for the variable "x", to do this, first you must add 121 to both sides of the function:
[tex](121)+0=x^2-121+(121)\\121=x^2[/tex]
Now apply square root to both sides of the function. Then, you get:
[tex]\±\sqrt{121}=\±\sqrt{x^2}\\\\\±\sqrt{121}=x\\\\x_1=11\\x_1=-11[/tex]
The value of the positive zero of the function is 11.
What is the simplified form of the equation 4/5n - 3/5 = 1/5n?
Answer:
n = 1 if you meant "(4/5)n - (3/5) = (1/5)n"
Step-by-step explanation:
There's some ambiguity here. Did you mean (4/5)n or did you
4
mean --------- ? Please use parentheses to eliminate this ambiguity.
5n
I'm going to assume that you meant to type in (4/5)n - (3/5) = (1/5)n.
Then we have (3/5)n = 3/5, or n = 1
The simplified form of the equation (4/5)n - (3/5) = (1/5)n is n=1. This is obtained by solving for n since it is an algebraic equation.
Find the value of n:Given that,
(4/5)n - (3/5) = (1/5)n
Taking terms with n to one side and constant to other side of the equation,
(4/5)n - (1/5)n = (3/5)
(4-1/5)n = (3/5)
(3/5)n = (3/5)
⇒n = 1
Hence the simplified form of the equation (4/5)n - (3/5) = (1/5)n is n=1.

Aja and Pete are biking on a trail.
Aja begins 2 miles ahead of Pete and bikes at an average speed of 3 miles per hour.
Pete bikes at an average speed of 4 miles per hour.
How much time will it take for Pete to catch up with Aja on the trail?
Answer:
2 hours
Step-by-step explanation:
Given in the question that,
speed of Aja = 3 miles/h
speed of Pete = 4 miles/h
we know that Aja is 2 miles away from Pete
Both will have covered same distance at the time they will catch up.
suppose time = x
distance covered = y
Formula to use
distance = speed x time
Equation 1
3x = y - 2
3x + 2 = y
Equation 2
4x = y
Equate both equation
3x + 2 = 4x
2 = 4x -3x
2 = x
Answer:
Pete will catch up Aja after 2 hours
Step-by-step explanation:
We can represent thsi problem as as system of equations.
Let
x = be the time in which both Aja and Pete starte biking, (in hours)
y = the number of miles traveled by each
Aja begins 2 miles ahead of Pete and bikes at an average speed of 3 miles per hour. This means
y_Aja = 3*x + 2
Pete bikes at an average speed of 4 miles per hour.
y_Pete = 4*x
Then, we can find the intersection point between the graphs, so we find the solution.
Please see attached picture below
Pete will catch up Aja after 2 hours

a circle with center (1, 2) passes through the point (0, 6). what is the equation of the circle
The equation of the circle is (x - 1)^2 + (y - 2)^2 = 17.
Explanation:The equation of a circle can be written in the form:
(x - h)2 + (y - k)2 = r2
Where (h, k) is the center of the circle and r is the radius.
In this case, the center of the circle is (1, 2) and it passes through the point (0, 6).
So, the distance between the center and the point is equal to the radius of the circle.
Using the distance formula, we can find the radius:
r = sqrt((0 - 1)2 + (6 - 2)2) = sqrt(1 + 16) = sqrt(17)
Therefore, the equation of the circle is:
(x - 1)2 + (y - 2)2 = 17
An inscribed angle is an angle formed by two radii that share an endpoint. (true or false)
Answer:
False
Step-by-step explanation:
False. An inscribed angle is formed by two chords (inside a circle).
Note: A central angle is an angle formed by two radii that share an endpoint.
The statement about an inscribed angle being formed by two radii is false. An inscribed angle has its vertex on the circle and is formed by two intersecting chords, whereas a central angle has its vertex at the center of the circle and is formed by two radii.
The statement that an inscribed angle is an angle formed by two radii that share an endpoint is false. An inscribed angle in a circle is actually formed by two chords that intersect on the circle. The vertex of the inscribed angle lies on the circle and its sides are made up of two chords of the circle. By contrast, an angle formed by two radii that share an endpoint is called a central angle. The central angle's vertex is the center of the circle, and it intercepts an arc.
Find the area of the trapezoid by decomposing it into other shapes.
A) 60 cm2
B) 69 cm2
C) 84 cm2
D) 99 cm2
Answer:
99 cm^2
Step-by-step explanation:
Solution 1: Don't decompose and instead use the trapeziod area theorem. (b1+b2)/2 * h. Using this we plug in the two bases and get (23+10)/2 *6 -->
16.5*6=99cm2
Solution 2: You follow the rules and decompose the trapeziod. Split it into two triangles and a rectangle. The area of the triangle on the left is (b*h)/2 which is equal to (3*6)/2 which is 9 cm2. Spliting the trapeziod gives the rectangle dimensions of 10x6. 10*6= 60cm2. Finally we must find the area of the triangle on the right. The height is 6cm in the diagram and the base would be the full base of the trapeziod(20+3)-(10+3) --> 23-13=10. Using the area formula for the triangle gives us 10*6/2 = 30cm2. To find the full area we must add all the shapes up, 9+60+30 = 99cm2

Random answers will be reported!
Answer:
Sin E=0.50
Step-by-step explanation:
Here we are given that DE || AB, and DB and AE are traverse lines to them meeting at point F.
By the properties of parallel lines intersected by a transverse we know that the alternate interior angles are equal.
If we extend DE and AE on both sides , we can see that A and E are equal as they forms alternate interior angles.
Hence
A=E
Sin A = Sin E
0.50=Sin E
Answer:
I got sin E = 0.5
Thus answer choice C being the correct choice

Answer:
The measure of SWX is 108.
Step-by-step explanation:
TX and QS are not perpendicular.
QRT and TRU are complementary (add to 90) not supplementary (add to 180)
The measure of SWX is 108 because angles on a line add to 180, and RWS is 72. 180 - 72 = 108
Answer:
The measure of <SWX is 108°
The second answer is actually Complementary.

A. The median of box plot A is greater than the median of box plot B.
B. Both the box plots A and B have the same median.
C. The interquartile range of box plot A is greater than the interquartile range of box plot B.
D. The median of box plot B is greater than the median of box plot A.
Answer:
the answer is D: the median of box plot B is greater than the median of box plot A.
Step-by-step explanation:
Answer: D. The median of box plot B is greater than the median of box plot A.
Step-by-step explanation:
We know that in a box-whisker plot, the vertical present in the box represents the median value of data and the length of box along the number line represents the interquartile range.
In the given picture, it can be seen that the box B is longer than box A.
It mean that the interquartile range of box plot B is greater than the interquartile range of box plot A.
Also, the vertical line in box A is present between 15 and 20 on number line but in box B it is present between 25 and 30.
It means that the median of box plot B is greater than the median of box plot A.
The width of a model train’s car measures 2.4 in. The scale is 1:56. What is the width of the actual train car to the nearest foot?
Answer:
11.2 feet
Step-by-step explanation:
The width of the actual train car, to the nearest foot, is 11 feet.
To find the width of the actual train car, we need to use the scale factor provided.
Given:
- Width of the model train's car = 2.4 inches
- Scale = 1:56
To find the actual width, we'll use the scale factor:
[tex]\[ \text{Actual width} = \text{Model width} \times \text{Scale factor} \][/tex]
First, we need to convert the width of the model train's car from inches to feet because the scale factor is given as a ratio. There are 12 inches in a foot.
[tex]\[ \text{Model width} = \frac{2.4 \text{ inches}}{12 \text{ inches/foot}} = 0.2 \text{ feet} \][/tex]
Now, we can find the actual width:
[tex]\[ \text{Actual width} = 0.2 \text{ feet} \times 56 = 11.2 \text{ feet} \][/tex]
