The solution of the composite function (f/g)(x) is [tex]\frac{-4x+3}{6+7x}[/tex]

Composite functions are when the output of one function is used as the input of another.

In other words, a composite function is generally a function that is written inside another function.

Composite function involves the composition of functions is combining two or more functions as a single function.

Therefore, let's solve the function below:

f(x) = -4x + 3

g(x) = 6 + 7x

Hence,

(f/g)(x) = f(x) / g(x)

The probability that the next number pointing north is between 2 and 7 is 13/18 .

1) The circle is divided into 9 parts.

Now the parts are uneven.

So the data about the spins is required to calculate the probability .

The total number of items in the box = 18

favorable outcomes (between 2 and 7) = 13 possible outcome.

Required probability

= favorable outcome / total outcome

= 13 / 18

2) Using the Venn diagram we can calculate the various parts of the problem:

Shoppers at big-box store or online or local store = sum of all the shoppers = 109+57+107+18+17+38+34 = 380 shoppers

The number of eraser Stefanie bought is 10.

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items, before tax.

Therefore, the number of eraser Stefanie bought can be calculated as follows;

let

x = number of eraser bought

Therefore,

4.25 = 1.75 + 0.25x

subtract 1,75 from both sides of the equation

4.25 - 1.75 = 1.75 - 1.75 + 0.25x

2.5 = 0.25x

divide both sides by 0.25

x = 2.5 / 0.25

x = 10

Therefore,

number of eraser = 10

The parameters in the question are given as

These parameters can be represented as

x₁ = -7 and x₂ = 5

(x, y) = (0, -2)

The quadratic function can be represented as

y = a(x - x₁)(x - x₂)

Substitute the known values in the above equation So, we have the following equation

y = a(x + 7)(x - 5)

At (x, y) = (0, -2), we have

-2 = a(0 + 7)(0 - 5)

Evaluate

a = -2/-35

The solutions of the equations are x = 1 and y = 2

The system of equations are

4x + 3y = 10

-4x + 5y = 6

Here we have to use the elimination method. Eliminate the x term and find the value of y term

Add both equation

3y + 5y = 10 +6

Add the like terms

8y = 16

y = 16 / 8

Divide  the terms

y = 2

Substitute the value of x in the first equation

4x + 3y = 10

4x + 3×2 =  10

Multiply the terms

4x + 6  = 10

4x = 10 - 6

4x = 4

x = 4 / 4

Divide the terms

x = 1

The measure of the Largest angle using the angle sum property of a triangle is: 80°

What is the Angle sum property of a triangle?

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180o, regardless of whether it is acute, obtuse, or right.

One of the most commonly applied properties in geometry is the triangle's angle sum property. Most often, the unknown angles are calculated using this attribute.

In the given figure, we have:

Measure of 1st angle = 64°

Measure of 2nd angle = (2x + 14)°

Measure of 3rd angle = (6x + 14)°

and we know the angle of the property,

using the  angle of property,

64° + (2x + 14)° + (6x + 14)° = 180°

⇒64° + 8x + 14° + 14° = 180°

⇒92°  + 8x = 180°

⇒ 8x = 180° - 92°

⇒8x = 88°

⇒ x = 11°

So,

Measure of 2nd angle = (2x11 + 14)°

Measure of 2nd angle = (36)°

Measure of 3rdangle = (6x11 + 14)°

Measure of 2nd angle = (80)°

Hence,

The measure of the Largest angle using the angle sum property of a triangle is: 80°

Line plot , because a small number of scores are reported individually

What is a line plot?

A line plot is a graph that shows data as points or check marks above a number line, indicating the frequency of each value.

If we need to compare two different groups , a line chart does have one advantage for visualizing frequency distributions

Given data ,

Total number of athletes = 15

The score points of athletes = { 1 , 2 , 3 , 4 , 5 }

The number of athletes = { 1 , 2 , 3 , 4 , 5 }

The best option to plot the line plot because of the data set

The line plot , a data visualization chart that more accurately represents the small data set, is chosen.

And , to begin, unlike a line plot , a histogram involves data ranges or intervals. A line plot uses a dot to represent each observation, whereas a histogram divides the data into intervals, masking the identity of each observation

Furthermore, because line plots are one of the simplest statistical plots, they are better suited to small to moderate-sized data sets. They are more effective than histograms at highlighting clusters and gaps

the square root of the number 59 is:

7.6811

You rounded to the nearest tenths place. The 6 in the tenths place rounds up to 7 because the digit to the right in the hundredths place is 8.

The volume V of the water in the cone as a function of the height h of the water is,

V = (1/48)πh³

Given, water is poured into a container in the shape of a right circular cone with a radius 4 inches and height 16 inches.

We have to express the volume V of the water in the cone as a function of the height h of the water.

Now, at any instant let the height of the water in the cone be h and radius of the water in the cone be r,

So, using the concept of similarity in triangles

r = h/4

Now, the volume of the water in the cone be,

V = (1/3)πr²h

V = (1/3)π(h/4)²h

What is linear programming?

When a linear function is exposed to multiple restrictions, linear programming maximizes or minimizes the function. This method determines the best way to use the resources that are currently available and aids managers in using the process to make decisions about the most efficient use of scarce resources, such as money, time, materials, and machinery. Linear programming has been useful for guiding quantitative decisions in business planning, industrial engineering, and—to a lesser extent—in the social and physical sciences.

For a pole-vaulter in training, the height the athlete will be able to pole-vault after t months of training is given by a mathematical formula. The formula is given below.

H(t) = 17 - 11e^(-0.02t)

We need to find the number of months after which she will be able to vault a height equal to 11 feet. We will substitute the value of height in the given equation.

11 = 17 - 11e^(-0.02t)

11e^(-0.02t) = 17 - 11

11e^(-0.02t) = 6

e^(-0.02t) = 6/11

Now, we will take the natural logarithm on both sides of the equation.
