In mathematics, a function is a rule that assigns a unique output or value to each input or element in a given set. It is a mathematical object that describes how one quantity (the output) depends on another quantity (the input).

A function can be represented by a graph, a table, or an algebraic equation. The input values are usually denoted by the variable x, while the output values are denoted by the variable y, f(x), or some other symbol. The notation f(x) is read as "f of x" and is used to represent the output value of the function when the input value is x.

A function can be defined in various ways:

Geometrically, by specifying a curve or surface in the plane or in space.

Algebraically, by specifying a formula or equation that gives the output in terms of the input.

Numerically, by specifying a table of input-output pairs.

Verbally, by giving a description of how the output depends on the input.

the y-intercept of the equation h=12−x represents the initial height of the candle when it is first lit, which is 12 inches in this case.

How to solve the question ?

In the given equation, h represents the height of the candle in inches and x represents the number of hours for which the candle has been burning.

The y-intercept of the equation is the point where the graph of the equation intersects the y-axis, which occurs when x is equal to 0. Substituting x=0 in the equation, we get:

h=12-0

h=12

Therefore, the y-intercept of the equation is 12, which means that when the candle is first lit (x=0), its height is 12 inches.

In the context of the burning candle, the y-intercept represents the initial height of the candle before it starts to burn. This is the height of the candle when it is first lit and before any wax has melted. As the candle burns and wax melts, the height of the candle decreases, and this is represented by the negative slope of the equation.

In summary, the y-intercept of the equation h=12−x represents the initial height of the candle when it is first lit, which is 12 inches in this case.

the radius of the track is approximately 420.38 feet.

Why is it?

The circumference of the circular track is 0.5 miles or 0.5 × 5280 = 2640 feet.

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

Therefore, 2640 = 2 × 3.14 × r

Simplifying the equation: 2640 = 6.28r

Dividing both sides by 6.28: r ≈ 420.38 feet

Therefore, the radius of the track is approximately 420.38 feet.

Circumference is the distance around the edge of a circle or any other curved, circular object. It is also the perimeter of the circle. It is calculated by multiplying the diameter of the circle by pi (π), which is a mathematical constant that is approximately equal to 3.14.

The equation of circle with endpoints at  (-3, 0) and (3, 0) is x² + y² = 9

The end points (-3, 0) and (3, 0) represent the endpoints of a diameter of the circle. The center of the circle is the midpoint of this diameter. We can find the midpoint of the diameter by averaging the x-coordinates and the y-coordinates of the endpoints:

Midpoint = ((-3 + 3)/2, (0 + 0)/2) = (0, 0)

So the center of the circle is at the point (0, 0). The radius of the circle is half the length of the diameter, which is:

Radius = 1/2 * distance between (-3, 0) and (3, 0)

= 1/2 * 6

= 3

Therefore, the equation of the circle with endpoints at (-3, 0) and (3, 0) is:

(x - 0)² + (y - 0)² = 3²

Simplifying:

x² + y² = 9

So the equation of the circle is x² + y² = 9.

Answer:

6

Step-by-step explanation:

The equation of a line perpendicular to y = -6 that contains the point (1, 3) is x = 1 .

We are given a line that runs through the point (1, 3) and is perpendicular to y = -6.

We want to write the equation for this line in slope-intercept form.

                           Slope-intercept form is y=mx+b,

where m is the slope and b is the value of y at the y intercept, hence the name. First, we need to find the slope (m) of the line.

                              Given line = y = -6

                            y = 0x - 6

compare with  y  = mx + C

therefore slope m = 0

the slope of the perpendicular line can be given as

M perpendicular = -1/m

M perpendicular = - 1/0

Keep in mind that we were given the line's perpendic subsequently, to find the slant of this line, we can do the accompanying condition

                                         0m=1

Partition the two sides by 0

                                                m = 1/0

This  is indistinct - subsequently, the line has a vague slant . If so, then, at that point, it implies the line is an upward line

An upward line is composed as

                                               x=k,

where k is the worth of x at the x side . The slope-intercept form cannot be used to write it.

                                   Substituting  1 for k

y- y₁ = m perpendicular - ( x- x₁)

y - 3 = - 1/0( x - x₁ )

0  = - ( x- 1 )

x-1 = 0

x = 1

because this value is the same as the value of x at every point along such a line; in this instance, as indicated by the point (1, 3), this value is 1.

Hence, the equation of a line perpendicular to y = -6 that contains point 1,3 is x = 1 .

What are linear equations?

The first-degree equations are linear equations. The straight line's equation can be found here. ax+by+c=0 is the most common form of a linear equation, where a and b are zeros.

Part 1:

Let x be the number of students.

Band A: Cost = $500

Band B: Cost $350 +$1.50x

The system of equations representing the cost of the two bands is:

CostA = 500

CostB = 350+ 1.5x

Part 2:

Let F be the fixed cost and R be the rate per student served.

From the given information, we can write two equations:

50R + F = 450

150R + F = 1050

Subtracting the first equation from the second, we

get:

100R = 600

Therefore, R = 6.

Substituting R in the first equation, we get:

50(6)+F450

Therefore, F = 150.

So, the caterer's fixed cost is $150 and the rate per student served is $6.

Part 3:

For 100 students:

CostA 500

CostB = 350+ 1.5(100) 500

Both bands have the same cost, but Band A has a lower variable cost.

So, we should choose Band A.

Total cost for 100 students = 500 + 150+ 6(100) =

$1250

Cost per ticket = Total cost / Number of students = 1250/100 = $12.50

For 200 students:

CostA = 500

CostB = 350+ 1.5(200) = 650

Band A still has a lower cost, so we should choose Band A.

Total cost for 200 students 500+ 150 + 6(200) = $1850

Cost per ticket = Total cost / Number of students =

1850/200 $9.25

Part 4:

Let D be the number of bouquets of daisies and R be the number of bouquets of roses.

The cost of daisies is $25 per bouquet and the cost of roses is $35 per bouquet. We want to spend no more than $500, so we can write:

25D +35R < 500

If we buy 15 bouquets of daisies, then we can spend at most $425 on roses:

25(15) + 35Rs 500

375 +35R ≤ 500

35R ≤ 125

If we buy 15 bouquets of daisies, then we can.

Mathematics College spend at most $425 on roses:

25(15)+35R ≤ 500

375 +35R≤ 500

35R ≤ 125

R≤ 3.57

We get x = -3 and y = 2 on solving 2x + 5y = 4; 2x - y = -8

Let's find y from the second equation in terms of x:

2x - y = -8

-y = -2x - 8

y = 2x + 8

Now, we may enter the following expression in place of y in the first equation:

2x + 5y = 4

2x + 5(2x + 8) = 4

Simplifying this equation, we get:

12x + 40 = 4

Subtracting 40 from both sides, we get:

12x = -36

Dividing both sides by 12, we get:

x = -3

Now we can substitute this value of x into our expression for y:

y = 2x + 8 = 2(-3) + 8 = 2

Hence, x= -3 and y= 2 are the answers to the system of equations.

The probability that a student chosen at random did not get a B 0.283 The probability of a student not getting a B is the number of students who did not get a B divided by the total number of students.

Outcome can be an event, such as the sum of two dice, or it can be a variable, such as the number of heads from a coin toss.

In this case, there are 21 students who did not get a B (2 male A's, 19 female A's, and 10 female C's), compared to a total of 74 students. Therefore, the probability that a student chosen at random did not get a B

= 21/74

= 0.283

To calculate this probability, we used the total number of students who did not get a B (21) divided by the total number of students (74).

This gives us the probability that a student chosen at random did not get a B.

In addition to using this method to find the probability of a student not getting a B, we can also find the probability of a student getting a B by subtracting the probability of not getting a B from 1.

In this case, the probability of getting a B would be

1 - (21/74)

= 0.71622.

This method can be used to calculate the probability of any outcome given the probabilities of all other outcomes.
