We can also check if the function's equation is in the form y = mx + b.

What is function's equation ?

A function's equation is a mathematical statement that defines the relation between the input (also known as independent variable) and output (also known as dependent variable) of a function. The equation is typically represented by the letter "y" for the output, and one or more letters for the input (usually "x").

To determine whether a function has a constant or variable rate of change, we need to find the slope or rate of change between two points on the function. If the slope remains the same no matter what two points we choose, the function has a constant rate of change and is linear. If the slope changes depending on the two points we choose, the function has a variable rate of change and is nonlinear.

To determine whether a function is linear or nonlinear, we can also check if the function's equation is in the form y = mx + b, where m and b are constants. If it is, the function is linear, otherwise it is nonlinear.

It's important to mention that, in order to have a definitive answer, we need the function to be defined.

I can provide you with a description of the graph.

The graph would have the distance on the y-axis and the time on the x-axis.

The first 60 miles of the journey would be represented by a straight line with a slope of 60/1=60, since the car is traveling at a constant speed of 60 mph.

The point where the first 60 miles ends would be (1,60) which is the time of one hour from London, the distance of 60 miles from London.

After the 30-minute break at the motorway services, the car would continue its journey at a constant speed of 70 mph. This part of the journey would be represented by a straight line with a slope of 70/1=70.

The point where the whole journey ends would be (4,200) which is the time of 4 hours from London, the distance of 200 miles from London.

Please note that it is assumed that the car doesn't stop during the second part of the journey.

Answer: Parallel

Step-by-step explanation:

To solve this question, we need to find the slopes of both lines q and r.

First, let's find the slope of line q.

Δx/Δy=-7/-6 = 7/6

Next, the slope of line r.

Δx/Δy=-7/-6 = 7/6

Both lines have the same slope.

Therefore, they are parallel.

Answer: The height of an object can be determined using the relationship between the height of an object, the length of its shadow, and the length of a reference shadow. This relationship is given by the formula:

Height of object = (Height of reference object x Length of object's shadow) / Length of reference shadow

Given that a 4-ft vertical post casts a 10-in shadow at the same time a nearby cell phone tower casts a 125-ft shadow, we can use this formula to find the height of the cell phone tower:

Height of the cell phone tower = (4 ft x 10 in) / 125 ft

To find the height of the cell phone tower, we have to convert the 10 inches to feet, since the reference object's height is in feet.

10 inches = 10/12 ft = 5/6 ft

Height of the cell phone tower = (4 ft x 5/6 ft) / 125 ft

Height of the cell phone tower = 20/125 ft = 16/125 ft = 128/1025 ft = 128/1025 * 12/12 in = 128/85 ft

So the cell phone tower is 128/85 ft or (128/85) * 12 = 128/7 ft = 18.285714 ft tall.

The cell phone tower's height is 18.285714 ft.

Answer: Dilation by 1/4 and translation

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. To find the slope between the two points (3,4) and (-1,2), we can use the slope-intercept form of a line, y = mx + b. The slope (m) is equal to the rise (change in y) over the run (change in x), or (y2-y1)/(x2-x1). In this case, the rise is (2-4) = -2 and the run is (-1-3) = -4, so the slope is (-2)/(-4) = 1/2.

2. To find the slope between the two points (-2,0) and (5,-3), we can use the same formula, (y2-y1)/(x2-x1). The rise is (-3-0) = -3 and the run is (5-(-2)) = 7, so the slope is (-3)/7 = -3/7

3. To find the slope between the two points (4,-5) and (4,2), we can use the same formula, (y2-y1)/(x2-x1). The rise is (2- (-5)) = 7 and the run is (4-4) = 0, so the slope is 7/0 which is undefined.

4. To find the slope between the two points (-1,3) and (5,3), we can use the same formula, (y2-y1)/(x2-x1). The rise is (3-3) = 0 and the run is (5-(-1)) = 6, so the slope is 0/6 = 0.

A photo with dimension 5 x 7 in is reduced so that the width becomes 4 in. The reduced size of the length of the photo is 5.6 in.

When two shapes are identical but differ in size, they are considered to be similar shapes. A similar shape can be created by scaling all of the lengths of the original shape. This means they've been stretched or shrunk in the same proportions. This is referred to as the scale factor.

In this case, the original photo and the smaller photo are similar shapes. Hence, the proportion of the corresponding sides have to be the same.

We can find the scale factor as:

Scale factor = reduced width / initial width

                   = 4 in. / 5 in. = 0.8

The length has to be reduces at the same scale factor. Therefore,

reduce length = 0.8 x 7 in = 5.6 in.

Answer:

Bonjour, qui pourrait me donner la réponse de cette exercice s’il vous plaît c’est pour mon DM de maths.

Step-by-step explanation:

=========================================================

Explanation:

Break the 3D figure into two pieces:

The relevant formulas we need are:

where r and h are the radius and height respectively.

The cylinder has radius r = 5 and height h = 17.8

V = pi*r^2*h

V = pi*5^2*17.8

V = 445pi

The cone has the same radius, but the height is h = 24-17.8 = 6.2

V = (1/3)*pi*r^2*h

V = (1/3)*pi*5^2*6.2

V = (155/3)pi

The total volume is then,

445pi+(155/3)pi

(1335/3)pi + (155/3)pi

(1335/3 + 155/3)pi

(1490/3)pi

That's the exact volume of this pencil-shaped figure. This exact volume is in terms of pi.

----------

Now to compute the approximate volume.

If you were to use pi = 3.14, then the approximate volume is

(1490/3)pi = (1490/3)*3.14 = 1559.5333 cubic cm

Here's what my calculator shows when computing the expression.

(1490/3)pi = 1560.32435128293

The calculator has a stored version of pi with more digits for better accuracy.

Both of those results round to   1560  cubic cm     when rounding to the nearest cubic centimeter.

Answer:

Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. There is no finite way to express them. ( examples: √2, π, e)

15% of that number is 39.

What is a percentage?

A percentage is a way to express a number as a fraction of 100. It is commonly used to represent a proportion or ratio of a number to a whole. For example, 10% of a number means 10/100 or 1/10 of that number, 25% means 25/100 or 1/4 of that number, and 15% means 15/100 or 3/20 of that number.

To find 15% of a number, if we know that 10% of it is 26, and 25% of it is 65, we can use algebra:

Let X be the number we're trying to find

10% of X = 0.10X = 26

25% of X = 0.25X = 65

We know that 15% is between 10% and 25% so we can use the proportionality between them:

15% of X = 0.15X = (15/10)*26 = 39

Hence, 15% of that number is 39.

A set comprises elements or members that can be mathematical objects of any sort, including numbers, symbols, points in space, lines, other geometric forms, variables, or even other sets. A set is the mathematical model for a collection of various things.

In set theory, the set containing every element in a collection is the union of all its sets. It is one of the fundamental operations that allows sets to be joined together and connected to one another. A union of zero sets is referred to as a nullary union, because it is by definition equivalent to the empty set.

The symbol "∩" can be used to represent the intersection of sets. According to the definition given above, the intersection of two sets A and B is the collection of all the items that are shared by both sets.
