What is the volume of a sphere with a radius of 8 m, rounded to the nearest tenth of a cubic meter?
radius= 8 m
to find:the volume of the sphere
solution:[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
[tex]v = \frac{4}{3} \times \pi \times {8}^{3} [/tex]
[tex]v = 2144.66058 \: {m}^{3} [/tex]
[tex]v = 2144.7 \: {m}^{3} [/tex]
therefore, the volume of the given sphere is 2144.7 cubic meters.
[tex]\large\boxed{Formula: V= \frac{4}{3}\pi {r}^{3}}[/tex]
In this question the radius is given so we'll simply have to substitute the values and solve.
Let's solve!
Substitute the values according to the formula.
[tex]V= \frac{4}{3}\times\pi\times{8}^{3}[/tex]
Calculator value:
[tex]V= 2144.660585 \: {m}^{3}[/tex]
Now, we'll have to round off to the nearest tenth.
The value in hundredths place is greater than 5 so, we will have to round up which means, we'll have to add 1 to the tenths place.
Final answer:
[tex]\large\boxed{V= 2144.7 \: {m}^{3}}[/tex]
Hence, the volume of the given sphere is 2144.7 cubic meters.

The following data points represent the total weight loss
(in kilograms) for each member of omar's final fitness
team. 61,90, 31, 35, 69, 37, 78
The histogram shows that the majority of Omar's Final Fitness Team had weight loss between 30 to 49 kg, with only a few members achieving higher weight loss of 60 to 69 kg.
To create a histogram from the given data, follow these steps:
Step 1: Determine the range of the data (largest value - smallest value): Range = 90 - 31 = 59
Step 2: Choose a number of classes for the histogram. A convenient number of classes is usually between 5 and 15. For this data set, we can choose 6 classes.
Step 3: Determine the width of each class by dividing the range by the number of classes:
Class width = Range / Number of classes
Class width = 59 / 6 = 9.83
Round the class width up to 10 to make it a convenient number.
Therefore, the class width is 10.
Step 4: Determine the lower limit of the first class. Choose a value that is equal to or less than the smallest data point.
Lower limit of first class = 30
Step 5: Create the frequency distribution table by counting how many data points are in each class:
| Class Interval | Frequency |
|:----:|:----:|
| 30 - 39 | 2 |
| 40 - 49 | 2 |
| 50 - 59 | 0 |
| 60 - 69 | 2 |
| 70 - 79 | 1 |
| 80 - 89 | 1 |
Step 6: Draw the histogram. On a horizontal axis, mark the class intervals. On the vertical axis, mark the frequency for each class. Draw vertical bars to represent the frequency in each class. Make the bars touch each other so that it shows a continuous distribution.
Here's the histogram of the given data:
```

What is the value of x in this figure?
Enter your answer in the box.
please help me i don't know what im doing
Answer:
y = 3x -4
Step-by-step explanation:
The two pairs of x and y values are used to find the slope of the line. That and one of the pairs is used to find the y-intercept. These values are put into the slope-intercept equation to give the equation of the line through the two points.
__
Each (x, y) pair represents a point on a graph. The slope-intercept equation for a line relates all the (x, y) pairs that lie on the line. That equation is ...
y = mx +b . . . . . . where m is the slope, and b is the y-intercept
slopeThe slope is the "steepness" of the line. It is positive when the line goes up to the right, and negative when the line goes down to the right. It is 0 for a horizontal line.
The slope is found from (x, y) pairs using the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . where (x1, y1) and (x2, y2) refer to different pairs
m = (8 -(-1))/(4 -1) = 9/3 = 3 . . . . using the (x, y) values from the table
y-interceptThe y-intercept (b) is the y-value where the line crosses the y-axis. It can be found by rearranging the slope-intercept equation shown above:
b = y - mx . . . . . . . for a line with slope m and a point (x, y) on the line
Using the first point listed in the table with the value of m we just found, we see that b is ...
b = -1 - 3(1) = -4 . . . . . . for (x, y) = (1, -1) and m = 3
equationNow that we have found m=3 and b=-4 for the points in the table, we can put these values in the slope-intercept equation:
y = mx +b
y = 3x -4 . . . . . equation of the relationship in the table
a car travels at an average speed of 40km/h for 2.2 hours how far did the car travel in km
Answer:
88km
Step-by-step explanation:
If a car travels 40 km in 1 hour, then that same car would travel 40*2.2 km in 2.2 hours.
So, the car travelled 88km in 2.2 hours
Remember that speed is a rate!
Answer:
speed=distance/travel time
distance=2*40+60*3=80+180=260 km
travel time=2+3=5 hrs
Average speed during entire journey=260/5=52 km/h

Rectangle KLMN is graphed on the coordinate plane below. On a coordinate plane, rectangle K L M N has points (2, negative 2), (5, negative 2), (5, negative 4), (2, negative 4). The figure is rotated 360° counterclockwise using the origin as the center of rotation. What is the location of the image of point K? (2, –2) (2, 2) (–2, 2) (–2, –2)
Answer: The correct option is (A) (2, -2).
Step-by-step explanation: Given that rectangle with vertices at K, L, M and N is graphed on the coordinate plane as shown in the figure.The figure is rotated 360° counterclockwise using the origin as the center of rotation.
We are to find the location of the image of point K after the rotation.
We know that
a rotation of 360° in counterclockwise direction about the origin map a point to itself. That is, the co-ordinates of the image point will be same as the original one.
From the figure, we see that the co-ordinates of point K are (2, -2).
Therefore, after rotation of 360° counterclockwise using the origin as the center of rotation,
the co-ordinates of the image of point K will also be (2, -2).
Thus, the location of the image of point K is (2, -2).
Option (A) is CORRECT.

h(t) = t² – 2t
Evaluate h (x + 2)
Need help I’m reviewing for a final (will leave good review)
Answer:
h(x + 2) = x² + 2x
Step-by-step explanation:
The base function is :
⇒ h(t) = t² -- 2t
⇒ h(t) = t (t - 2)
Substitute x + 2 in place of t :
⇒ h(x + 2) = (x + 2) (x + 2 - 2)
⇒ h(x + 2) = (x + 2)(x)
⇒ h(x + 2) = x² + 2x
[tex]h(t) = t^2 -2t\\\\h(x+2) = (x+2)^2 - 2(x+2)\\\\~~~~~~~~~~~~=x^2 +4x + 4 -2x -4\\\\~~~~~~~~~~~~=x^2 +2x[/tex]

Given f(x) and g(x) = k•f(x), use the graph to determine the value of k.
Step-by-step explanation:
the slope of f(x) = 1
for every increase of x by 1 also y increases by 1.
the slow of g(x) = -2
for every increase of x by one y decreases by 2.
so, we see, as
g(x) = k × f(x)
k = g(x) / f(x) = slope g / slope f = -2/1 = -2
why ? because both functions are linear functions (lines).
they look like
y = ax + b
with a being the slope of the line.
so, when multiplied by k, this is kax + kb, and we see k as factor already in the slope of the line itself.

The solution to the system of equation is (4.75, -11)
3.2x + 0.5y = 4.2
-1.6x -0.5y = 3.4
How to solve system of equation?
3.2x + 0.5y = 4.2
-1.6x -0.5y = 3.4
add equation(i) to equation(ii)
Therefore,
1.6x = 7.6
divide both sides by 1.6
x = 7.6 / 1.6
x = 4.75
Therefore,
3.2(4.75) + 0.5y = 4.2
0.5y = 4.2 - 15.2

Answer:
The solution is x=4.75 and y = -22
Step-by-step explanation:
To find the solution to the system of equations, we will follow the steps below:
3.2x + 0.5y = 4.2 --------------------------------------------------------------------------(1)
-1.6x -0.5y = 3.4 ----------------------------------------------------------------------------(2)
add equation (1) and equation (2)
1.6x =7.6
Divide both-side of the equation by 1.6 to get the value of x
1.6x /1.6 =7.6/1.6
x =4.75
substitute x = 4.75 into equation (1) and solve for y
3.2(4.75) + 0.5y = 4.2
15.2 + 0.5y = 4.2
subtract 15.2 from both-side of the equation
15.2 - 15.2 + 0.5y = 4.2-15.2
0.5y = -11
Divide both-side of the equation by 0.5
0.5y/0.5 = -11/0.5
y = -22
The solution is x=4.75 and y = -22

What is the range of F?
The range of f as shown in the graph is -6 ≤ f(x) ≤ 5. The correct option is A. -6 ≤ f(x) ≤ 5
Determining the range of a functionFrom the question, we are to determine the range of f.
The range of a function is the set of its possible output values.
The graph of the function, f, is shown in the diagram.
From the graph,
The minimum value of f on the x-axis is -6. That is, f(x) ≥ -6
and
The maximum value of f on the x-axis is 5. That is, f(x) ≤ 5
Combining the two expressions, we get
f(x) ≥ -6 and f(x) ≤ 5
That is,
-6 ≤ f(x) and f(x) ≤ 5
∴ -6 ≤ f(x) ≤ 5
Hence, the range of f as shown in the graph is -6 ≤ f(x) ≤ 5. The correct option is A. -6 ≤ f(x) ≤ 5
