Step-by-step explanation:

On a graph, you can see wether or not you have a function by doing the VLT, or vertical line test. Hold a pen or pencil vertically on the paper on move it from left to right. If no 2 points touch the pencil at once, it's a function.

Another way to find out is if any two different points have the same x coordinate. If there is a match, this is not a function. For example, 3,4 and 3,9 cause the graph to not be a function.

Hello! I wrote the complete question in a comment above. The volume of a cylinder is defined as:

[tex]V_{c}=\pi r^2 h \\ \\ r:radius \\ \\ h:height[/tex]

While the volume of half a sphere is:

[tex]V_{hs}=\frac{2}{3}\pi r^3[/tex]

Since we have 2 half spheres, then the volume of these is the same as the volume of a sphere:

[tex]V_{s}=\frac{4}{3}\pi r^3[/tex]

Then, the composite figure is:

[tex]V=\pi r^2 h +\frac{4}{3}\pi r^3 \\ \\ V=\pi r^2(h+\frac{4}{3}r)[/tex]

The radius of the cylinder is the same of the radius of each half sphere. So:

[tex]r=5mm \\ \\ h=10mm \\ \\ \\ V=(3.14) (5)^2((10)+\frac{4}{3}(5)) \\ \\ V=25(3.14)(10+\frac{20}{3}) \\ \\ \boxed{V\approx 1308.33mm^3}[/tex]

Answer:

Step-by-step explanation:

(We use the pythagorean theorem)

3-(-1) = 4

-2-1 = -3

4x4 + -3 x -3 = 16 x 9 = 144

line e: 12

2-(-1) = 3

2-(-1) = 3

3x3 + 3x3 = 9 x 9 = 81

line f: 9

Therefore, line e is longer!

Hope this helps!   .ω.

Without specific figures or numerical data, we cannot conclusively calculate the exact lengths of segments e and f. However, geometric principles suggest that segment f, if similar to a hypotenuse, would be longer. Accurate measurement or calculations based on the context (geometry, trigonometry, physical surveying) are required to determine the length of segments.

To calculate the exact lengths of segment e and segment f, we need more specific information from the given figures. However, based on the information provided, we can infer certain principles that could lead us to a conclusion. The hypotenuse of a right-angle triangle, as mentioned, is always the longest side, which implies that the length of segment f, being akin to a hypotenuse, would be longer than segment e if these segments were sides of a right-angled triangle. Additionally, the concept of eccentricity described for an ellipse informs us about the ratio of distances and could be applied if the segments were part of an elliptical geometry. The surveyor's tapes information suggests that lengths must be measured accurately, taking into account environmental factors such as temperature, because this can affect the length measurements. Without specific numerical data or figures to reference, we cannot determine with certainty which segment is longer, but the principles outlined can guide us to make an educated conclusion once all data is available.

In general, when comparing two segments to determine which is longer, measurement tools or mathematical calculations are utilized based on the context, such as geometry, trigonometry, or physical measurement in the case of surveying. As per the given text, if the discussion revolves around visual illusions where segments appear different in length despite being the same, then careful measurement is necessary to establish their actual lengths.

Step-by-step explanation:

In this question, the student is asked to compare mean, median, mode, and range for a given data set. Among these measures, the range, being 17, is the greatest.

The question given is asking for the greatest measure among the data set, which is 3,3,4,5,6,8,16,20. The measures being referred to are likely statistical measures such as mean, median, mode, and range.

The mean is the sum of all the numbers divided by the total count of the numbers, the median is the middle value when the numbers are arranged in order, the mode is the number that appears most frequently, and the range is the difference between the largest and smallest numbers.

To find the mean, we calculate (3+3+4+5+6+8+16+20)/8=7.875. The median is the average of the two middle numbers since we have an even count, (5+6)/2 = 5.5. This data set's mode is 3 since 3 repeats only. The range is 20 - 3 = 17.

Comparing these measures, we see that the range, with a value of 17, is the greatest.

The radius is half the diameter, so is (5/2) m. Then the volume is ...

  V = (4/3)π(5/2 m)³ = (4/3)(125/8)π m³ = (125/6)π m³

Answer:

No

Step-by-step explanation:

Three segments 4cm, 6cm, and 11cm cannot form a right triangle because if they could, then by Pythagorean theorem, 4^2 + 6^2 = 11^2, which is not true.

Moreover, the three segments cannot form an acute or obtuse triangle because by Triangle Inequality Theorem, the sum of two sides has to be greater than the third side. Here, (4cm + 6cm) is NOT larger than 11cm, and thus you cannot form a triangle.

Using triangle concepts, it is found that the sides with these lengths cannot form a triangle.

In a triangle, the sum of the lengths of the two smaller sides has to be greater than the length of the larger side.

In this problem:

[tex]4 + 6 = 10 < 11[/tex]

Since the larger side length is greater than the sum of the lengths of the smaller sides, a triangle cannot be formed.

Answer:

B) 3x+5

Step-by-step explanation:

Let's suppose that x is equal to the sum of a number.  That means, that 3x needs to be somewhere in the variable equation.  "And 5", means to add, so +5 also needs to be somehwere in the equation.  Giving you 3x + 5 as the answer.  Now you might be thinking, "But what about C? Isn't it basically the same answer as B?"  The answer to THAT question is NO.  For it to be the same as B, you would have to get rid of the parenthesis.  This is because when there's a parenthesis, it means that it is the first thing you have to do in the equation.  But that is not what we want.  We do not want the sum of a number to be added to 5.  We want it to be multiplied by 3.  So that is why C is the not the same as B.  B is yoir correct answer.

Slope = -2/3 (Answer choice "a.")

Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

y = -2/3x +5

This is in the form y = mx+b where m is the slope and b is the y intercept

-2/3 is the slope

The line perpendicular has a negative reciprocal slope or - 1 over the slope

- 1 /(-2/3)

-1 * (-3/2)

The slope of the line that is perpendicular is 3/2

Given:

[tex]y-3=\frac{1}{2}(x+3)[/tex]

Point = (8, 4)

To find:

The slope-intercept form of the equation of the line.

Solution:

[tex]$y-3=\frac{1}{2}(x+3)[/tex]

Slope of this line = [tex]\frac{1}{2}[/tex].

Slope of the line is same as the slope of  [tex]y-3=\frac{1}{2}(x+3)[/tex].

Slope of the line (m) = [tex]\frac{1}{2}[/tex]

General form of line:

y = mx + b

[tex]y=\frac{1}{2} x+b[/tex] ---------- (1)

It contains the point (8, 4). Substitute x = 8 and y = 4 in (1).

[tex]4=\frac{1}{2}( 8)+b[/tex]

[tex]4=4+b[/tex]

Subtract 4 from both sides, we get

b = 0

Substitute b = 0 in (1).

Equation of the line:

[tex]y=\frac{1}{2} x+0[/tex]

[tex]$y=\frac{1}{2} x[/tex]

Complete the sentence:

[tex]y=\frac{1}{2} x[/tex]; I used the general form of a line in slope-intercept form, y = mx + b. The slope, m is [tex]\frac{1}{2}[/tex]. Then I substituted 8 for x and 4 for y into the standard form and solved for b, which is 0.

Answer:

The diameter is 8 inches

Step-by-step explanation:

This problem bothers on mensuration of solid shapes, this in particular a cylindrical

Given data

Volume of cylinder in inches v=301.44in^3

Height of the bucket h= 6 inches

Radius r=?

To solve for the diameter we neeed to solve for the radius and multiply It by 2 to get the diameter

We know that the volume of a cylinder is given as

v= πr^2h

301.44= 3.142*r^2*6

301.44= 18.85*r^2

r^2= 301.44/18.85

r^2= 15.99

r=√15.99

r=3.998in

We know that the

diameter d =2r

Therefore d= 3.99*2

d= 7.997in

≈ d = 8 inches

Answer:

B= 36cm squared

h = 4 cm

V = 48 cm cubed

Step-by-step explanation:

A square pyramid has a square base. The edge length are all equal.

Given that:

base length (b) = 6 cm and slant height (l) = 5 cm.

The height and the slant height form a right triangle i.e the slant height is the hypotenuse, the base of the triangle is the distance from the center of the square to the edge which is half of the base length (b/2). The height of the pyramid (h) is given as:

l² = h² + (b/2)²

h² = l² - (b/2)²

h² = 5² - (6/2)²

h² = 25 - 9

h = √16 = 4 cm

The area of the base = b² = 6² = 36 cm²

The volume of the pyramid (V) = 1/3 × b² × h = 1/3 × 6² × 4 = 48 cm³

Answer:

(-4,1)

Step-by-step explanation:

(-1,4)  is the image of (4,-1) after a reflection over the line y=x

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph

When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their place.

So for the point (4,-1),the reflected image will be (-1,4)

Hence, (-1,4)  is the image of (4,-1) after a reflection over the line y=x

Answer:

Ashley is faster.

Step-by-step explanation:

I find it is easiest to convert into decimals.

Ashley ran 5/8 mile in 4 1/2 minutes.

5/8  is 0.625

Josh ran 3/4 mile in 5 minutes 15 seconds.

3/4 is 0.75

It looks like Josh won because his number is closer to 100, but, Ashley ran 0.625 mile faster than he ran 0.75 mile.

But then again, Josh ran more than her. Who won? Here is the answer.

Josh can run 0.75 mile in 5 minutes 15 seconds.

Ashley can run 0.625 miles in 4 1/2 minutes.

(4 + 1/2) ÷ 0.625 = 7.2

(5 + .15)  ÷ 0.75 = 6.8

7.2 is more & closer to 10.

So to sum it up, Ashley is faster.

To determine who's the faster runner, we calculate the speed of each runner by dividing the distance they run by the time it takes. Josh is slightly faster than Ashley because he covers more distance per minute.

In this problem, we are comparing the speeds of Ashley and Josh. Speed is calculated by dividing the distance traveled by the time it took to travel that distance. In Ashley's case, she runs 5/8 miles in 4 minutes and 30 seconds, or 4.5 minutes. So, her speed is (5/8) / 4.5 = 0.139 miles per minute.

Josh runs 3/4 miles in 5 minutes and 15 seconds, or 5.25 minutes. His speed is then (3/4) / 5.25 = 0.143 miles per minute.

We can see that Josh is slightly faster than Ashley because his speed (0.143 miles per minute) is higher than Ashley's speed (0.139 miles per minute).
