When a = 1, then a + 4 = 5

When a = 2, then a + 4 = 6

When a = 3, then a + 4 = 7

When a = 4, then a + 4 = 8

When a = 5, then a + 4 = 9

and the pattern cοntinues.

Answer:

These distances show that AB, which is only 10 nautical miles apart, and AB are the closest pair of islands.

Step-by-step explanation:

We must first locate the three pairs of islands in order to establish which pair is nearest before determining the safest route for the ship.

Give the three islands the letters A, B, and C. The three island groups are designated as AB, AC, and BC. Finding the closest pair is necessary.

We can leverage the separation between the islands to do this. Assuming that the islands are separated by the following distances:

A and B are separated by 10 nautical miles.

A and C are separated by 15 nautical miles.

B and C are separated by 12 nautical miles.

These distances show that AB, which is only 10 nautical miles apart, and AB are the closest pair of islands.

The second x - intercept on the graph of a car that has been travelling for 8 hours, represents the end of the car's journey.

To show a car's journey on a graph with two x-intercepts, determine the scale for your x-axis and y-axis based on the range of values for your car's journey.

The x-intercepts represent the points where the car starts and ends its journey. These points should be plotted on the x-axis at the appropriate values based on your scale. Once you have plotted the x-intercepts and any intermediate points, connect them with a line to show the car's journey.

Answer:

£6.8

Step-by-step explanation:

to make 1 litre of drink juice and lemonade are in the ratio

= 1: 4

juice costs £6 per litre

lemonade costs 50p per litre

to make 1 litre lemonade will cost 4 * 50p = 200p

1£ = 250p

thus, 200p = £.8

thus, cost to make 1 litre of the fruit drink is £6.8

Answer: Let's call the base of the triangle "b" and the height of the triangle "h". We are given that the sum of the base and the height is 22 cm, so we can write:

b + h = 22

We want to find the dimensions for which the area of the triangle is a maximum. The formula for the area of a triangle is:

A = (1/2)bh

We can use the equation b + h = 22 to solve for h in terms of b:

h = 22 - b

We can substitute this expression for h into the formula for the area:

A = (1/2)b(22 - b)

Simplifying this expression, we get:

A = 11b - (1/2)b^2

To find the value of "b" that maximizes the area, we can take the derivative of this expression with respect to "b" and set it equal to zero:

dA/db = 11 - b = 0

Solving for "b", we get:

b = 11

Substituting this value of "b" back into the equation b + h = 22, we get:

h = 22 - b = 22 - 11 = 11

Therefore, the dimensions for which the area of the triangle is a maximum are:

base = 11 cm

height = 11 cm

And the maximum area is:

A = (1/2)bh = (1/2)(11 cm)(11 cm) = 60.5 square cm

The commercial message that need to be run on every medium to maximize the audience is x = 15, y = 7 and z = 12.

A mathematical method called linear programming is used to maximise a linear objective function under the restrictions of linear equality and inequality. Finding choice variable values that maximise or decrease the objective function while meeting the limitations is required.

Let us suppose the number of advertisement run on television = x.

Let us suppose the number of advertisement run on radio = y.

Let us suppose the number of advertisement run on online = z.

Then,

140,000x + 18,000y + 30,000z

The constraints on the ads run on are as follws:

1,500x + 200y + 550z <= 24,100 (budget constraint)

x <= 15 (television usage limit)

y <= 19 (radio usage limit)

z <= 12 (online usage limit)

y <= 0.45(x+y+z) (radio usage limit as a percentage of total usage)

x >= 0.15(x+y+z)

Using the linear programming model we have:

x = 15, y = 7 and z = 12.

Substitute the value of x, y, and z:

140,000(15) + 18,000(7) + 30,000(12) = 2,910,000

Hence, the commercial message that need to be run on every medium to maximize the audience is x = 15, y = 7 and z = 12.

To find zx and zy, we need to take partial derivatives of z with respect to x and y. Taking z with respect to x, we get zx = 3x2 + 12xy and zy = 6x + 16y. Taking z with respect to y, we get zy = 6x + 16y and g(x, y) = 3xy - 7x. Therefore, gx = 3y - 7 and gy = 3x.

A derivative is a measure of how much a function changes as its input changes. More specifically, the derivative of a function at a particular point is the slope of the function at that point, which describes how quickly the function is changing at that point.

Geometrically, the derivative of a function at a given point can be thought of as the slope of the tangent line to the function at that point.

To find zx and zy, we need to take partial derivatives of z with respect to x and y, respectively.

Given z = [tex]x^3 + 6x^2y + 8y^2[/tex],

Taking partial derivative of z with respect to x, we get:

zx = [tex]3x^2 + 12xy[/tex]

Taking partial derivative of z with respect to y, we get:

zy = 6x + 16y

Therefore, zx = 3x^2 + 12xy and zy = 6x + 16y.

Given g(x, y) = 3xy - 7x,

Taking partial derivative of g with respect to x, we get:

gx = 3y - 7

Taking partial derivative of g with respect to y, we get:

Answer: The range is the best measure of variability for the given data set and its value is 500.

The range is the difference between the maximum and minimum values in a data set, and in this case, the maximum value is 1100 and the minimum value is 600, so the range is 1100-600=500. The range gives us an idea of how spread out the data is, but it can be affected by outliers. In this case, it seems like a reasonable measure of variability since there are no extreme values that would greatly affect the range.

Step-by-step explanation:

From the data of the number of meters swam by students , range is the best measure of variability and equals 500

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the data set be represented as A

Now , the value of A is

A = { 600, 750, 800, 850, 900, 1100 }

The appropriate measure of variability for the given data is the range. The range is the difference between the largest and smallest values in the data set.

And , range = 1100 - 600

R = 500

Hence , the range of the data set is R = 500

The equation y = (-2/3)x + 6 represents a line that is decreasing from left to right and intersects the y-axis at the point (0, 6).

The slope refers to the measure of the steepness of a line or a curve. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line or the curve.

The equation of a line can be written as with the help of slope intercept form is given by:

y = mx + b

Where "b" is the y-intercept and "m" is the line's slope of the line.

In the equation y = (-2/3)x + 6, we can see that the slope 'm' is -2/3, which means that for every unit increase in x, the y-value decreases by 2/3 of a unit. This tells us that the line represented by this equation is decreasing (i.e., sloping downwards) from left to right.

The y-intercept 'b' is 6, which means that the line intersects the y-axis at the point (0, 6). This is the starting point of the line, where the value of y is 6 when x is 0.

Therefore, the equation y = (-2/3)x + 6 represents a line that is decreasing from left to right and intersects the y-axis at the point (0, 6).

Answer:

two are supplementary. the measure of one of these angles is 12 degrees less than one-third the measure of the other.what is the measure of each angle

Let's call the measures of the two angles x and y, where x is the larger angle. We know that the two angles are supplementary, which means they add up to 180 degrees:

x + y = 180

We also know that one of the angles (let's say y) is 12 degrees less than one-third the measure of the other angle (x):

y = (1/3)x - 12

Now we can substitute the second equation into the first equation to solve for x:

x + (1/3)x - 12 = 180

Multiplying both sides by 3 to get rid of the fraction, we have:

3x + x - 36 = 540

Combining like terms, we get:

4x - 36 = 540

Adding 36 to both sides, we get:

4x = 576

Dividing both sides by 4, we get:

x = 144

Now we can use the first equation to solve for y:

144 + y = 180

Subtracting 144 from both sides, we get:

y = 36

Therefore, the measures of the two angles are 144 degrees and 36 degrees.

The sum of the sides of a regular polygon is 96ft, find the measure of it side.

Let's say that the regular polygon has n sides, and each side has length s. The formula for the sum of the sides of a regular polygon is:

sum of sides = n * s

We know that the sum of the sides is 96ft, so we can write:

96 = n * s

We want to find the length of each side, so we need to isolate s on one side of the equation. We can do this by dividing both sides by n:

s = 96/n

Now we can substitute this expression for s into the formula for the perimeter of a regular polygon:

Perimeter = n * s

Perimeter = n * (96/n)

Simplifying this expression, we get:

Perimeter = 96

We know that the perimeter of a regular polygon is the sum of the lengths of all its sides, so we can divide the perimeter by the number of sides to find the length of each side:

s = Perimeter / n = 96 / n

Therefore, the length of each side of the regular polygon is 96/n feet. We cannot determine the value of n from the given information in the problem.
