A. Plot points that show the volume when r=1, r=2, r=3, and .r=4.
B. Show your reasoning.
Answers
To plot points that show the volume of a sphere for different values of the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr^3
For different values of the radius, we can substitute those values into the formula and calculate the corresponding volume.
A. Plotting points for r = 1, 2, 3, and 4:
When r = 1, V = (4/3)π(1)^3 = (4/3)π ≈ 4.19
When r = 2, V = (4/3)π(2)^3 = (4/3)π(8) ≈ 33.51
When r = 3, V = (4/3)π(3)^3 = (4/3)π(27) ≈ 113.1
When r = 4, V = (4/3)π(4)^3 = (4/3)π(64) ≈ 268.1
We can plot these points on a graph with radius on the x-axis and volume on the y-axis:
B. Reasoning:
As we can see from the formula for the volume of a sphere, the volume increases rapidly as the radius increases. In fact, the volume increases with the cube of the radius, which means that a small increase in radius can result in a significant increase in volume. This is why we see such a rapid increase in volume as we increase the radius from 1 to 4.
The graph of the volume of a sphere versus its radius is a curve that starts at zero when the radius is zero (i.e., a point) and increases rapidly as the radius increases. It is a smooth, continuous curve that does not have any sharp turns or corners. This is because the formula for the volume of a sphere is a smooth, continuous function of the radius, with no sudden jumps or changes.
Calculate the distance between the ordered pairs (1, 0) and (-4, 0). Show your work
Answers
Answer: 5
Step-by-step explanation:
The formula for distance is d = √((x2-x1)2 + (y2-y1)2)
Substitute the x's and the y's for the ordered pairs.
d=√ (1-(-4))²+(0-0)²
=√ (5)²+(0)²
=√(25)
= 5

A tree grows 1.5 feet per year. The tree is now 6 feet tall. Which sets of steps show ways to determine how many years the tree will take to be 27 feet tall?
Select the TWO correct answers.
A. 1.5x+6=27
1.5x=21
x=14
The tree will take 14 years to be 27 feet tall.
B. 27-6=21
21÷1.5=14
The tree will take 14 years to be 27 feet tall.
C. 1.5(x+6)=27
x+6=18
x=12
The tree will take 12 years to be 27 feet tall.
D. 1.5x+6=27
x+6=18
x=12
The tree will take 12 years to be 27 feet tall.
E. 27÷1.5=18
18-6=12
Answers
Answer:
Step-by-step explanation:
Answers are A and B.
Facts given are :
Current height = 6 ft
Growth per year = 1.5 ft
Final height = 27
Explanation for A:
Assume it takes 'x' number of years.
initial height + growth in 'x' years = Total height of the tree after 'x' years
6 + 1.5x = 27
1.5x = 27 -6 = 21
(1.5 can be written as 3/2) 3x/2 = 21
3x = 42
x = 14
hence, number of years = 14
Explanation for B:
After 'x' years,
Final height - initial height = Growth in 'x' years
27 - 6 = Growth in 'x' years
21=Growth in 'x' years = 1.5x
21= 3x/2
42=3x
14=x
hence, number of years = 14

In the scale drawing, the length of the room is 14 inches. The length of the actual multipurpose room is 112 feet.Using the above as a guide, we have the following:
Scale factor = scale length : actual length
substitute the known values in the above equation, so, we have the following representation
Scale factor = 14 in : 112 feet
Evaluate
Scale factor = 1 inches : 8 feet
Hence, the scale factor is 1 inches : 8 feet

Which part of this box plot includes about 50% of the data?
A.

B.
The box, from 44 to 52
C.
The lower whisker, from 34 to 44
D.
The upper whisker, from 52 to 59
Answers
Answer:
B
Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.
The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.
Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.

Bjorn is making aush, and he does not have enough of all the ingredients. He decides to make 5/6 of a whole recipe, which means he uses 1 1/4 L of water.
How much water is in a whole recipe?
____?
Answers
Answer:
1[tex]\frac{1}{2}[/tex]
5/6 of the whole recipe = 1 1/4 L of water
1 whole recipe = (1 1/4 L of water) / (5/6)
To divide a fraction by another fraction, we can multiply by the reciprocal of the divisor. Therefore, we can simplify the above expression as follows:
1 whole recipe = (1 1/4 L of water) * (6/5)
Multiplying 1 1/4 L by 6/5, we get:
1 whole recipe = (5/4 L) * (6/5) = 30/20 L = 1 1/2 L
Therefore, a whole recipe of aush requires 1 1/2 L of water.

Determine the direction and degree of rotation used to create the image.
90° counterclockwise rotation
270° clockwise rotation
90° clockwise rotation
180° counterclockwise rotation
Answers
Answer: 90° clockwise rotation
Step-by-step explanation:
The rules for rotation are below:
90° clockwise rotation = (x, y)→(y, -x)
270° clockwise rotation = (x, y)→(-y, x)
180° counterclockwise rotation = (x, y)→(-x, -y)
90° counterclockwise rotation = (x, y)→(-y, x)
Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.
Therefore, the answer is 90° clockwise rotation.

This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
Step-by-step explanation:
The given equation is:
4 = u + at
where u = 17, a = 4, and t = 8.
Substituting the given values, we get:
4 = 17 + 4(8)
Simplifying the right-hand side:
4 = 17 + 32
Combining like terms:
4 = 49
This is not a valid equation, as the left-hand side is not equal to the right-hand side.
Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.
