The requied solution are (f+g)(x) = 10x² + 10 - 5x and (f-g)(x) = 10x² + 6 + 5x.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question, as follows:

f(x) = 10x² + 8 and g(x) = 2 - 5x

To find (f+g)(x) we add f(x) and g(x) term by term.

(f+g)(x) = f(x) + g(x)

Substitute the values of given functions, and we get

(f+g)(x) = 10x² + 8 + (2 - 5x)

(f+g)(x) = 10x² + 10 - 5x

To find (f-g)(x) we subtract g(x) from f(x) term by term.

(f-g)(x) = f(x) + g(x)

(f-g)(x) = 10x² + 8 - (2 - 5x)

(f-g)(x) = 10x² + 6 + 5x

The average rate of change of these function f(x), g(x), h(x) on interval [4, 7] from least to greatest is f(x)<g(x)<h(x) with values A1 = -7.5 < A2 = -6 < A3 = -3.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

Average rate of change of any function say S(x) on [a,b] is -

A = [S(b) - S(a)]/b-a....(1)

Now. for function f(x) on interval [4, 7].

Here, use values of f(4) and f(7) from graph and find value of f(x)=y for x=4 and value of f(x)=y for x=7.

f(4) = -10, f(7) = 5

Substitute the values in equation (1) -

A1 = [f(7) - f(4)]/(4 - 7)

A1 = [5 - (-10)]/-2

A1 = 15/-2

A1 = -7.5

Average rate of change for function g(x) on interval [4, 7].

Here, use the values of g(4) and g(7) from table.

g(4) = 7, g(7) = 19

Substitute the values in equation (1) -

A2 = [g(7) - g(4)]/(4 - 7)

A2 = [19 - 7]/-2

A2 = 12/-2

A2 = -6

Average rate of change for function h(x) = x² - 9x + 5 on interval [4, 7].

Here, use the values of h(4) and h(7) by putting x = 4 and x = 7 in function h(x).

h(4) = x² - 9x + 5

h(4) = (4)² - 9(4) + 5

h(4) = 16 - 36 + 5

h(4) = -15

h(7) = x² - 9x + 5

h(7) = (7)² - 9(7) + 5

h(7) = 49 - 63 + 5

h(7) = -9

Substitute the values in equation (1) -

A3 = [h(7) - h(4)]/(4 - 7)

A3 = [-9 - (-15)]/-2

A3 = [-9 + 15]/-2

A3 = 6/-2

A3 = -3

Now, average rate of change of these function f(x), g(x), h(x) from least to greatest is f(x)<g(x)<h(x).

For the given condition number of laps "l" is the independent variable.

A symbol (often a letter) is used in mathematics to represent an unknowable numerical value in an equation or algebraic statement. A variable can be defined as a quantity that is changeable and not fixed. Variables are crucial since they make up a significant portion of algebra.

Given The amount of time, t, to finish a race and the number of laps, I,

there are two types of variables,

dependent and independent variables,

In an algebraic equation, an independent variable is one whose values are not impacted by changes. When there are two variables in an algebraic equation, x and y, and each value of x depends on every other value of y, x is an independent variable, and y is a dependent variable.

for the given condition,

the time taken to finish the race directly varies with the number of laps,

The area of the square is given by:

A = x^2 - 16x + 64

Remember that the area of a square of side length S is given by the formula:

A = S^2

Here we know that the side length is x - 8, then we can just replace that on the formula above to get:

A = (x - 8)^2

Now we can expand that:

A = (x - 8)^2 = (x - 8)*(x - 8)

A = x^2 - 16x + 64

This is because it is a numerical measurement describing a characteristic of a sample. A statistic is a value calculated from a sample, whereas a parameter is a value calculated from a population. In this case, the sample is the 40 randomly selected members of the health and fitness club, and the statistic is the average weight of those members. This statistic is used to make inferences about the larger population of all members of the health and fitness club, but it is not the same as the parameter, which would be the true average weight of all members of the club.

"At least one digit is present to the left of the decimal point in all cases" and "the exponent can be a positive or negative integer" are the correct option for the given question.

Decimal numbers, also known as base-10 numbers. They use a system of digits from 0 to 9 and a decimal point to represent values. The decimal point separates the integer part of the number from the fractional part.

For example, in the decimal number 56.36, 56 is the integer part and 36 is the fractional part.

Hence, at least one digit is present to the left of the decimal point in all cases.

In scientific notation, the exponent is used to represent very large or very small numbers. The number is written in the form of a x [tex]10^n[/tex] where 'a' is a decimal number between 1 and 10 (inclusive) and 'n' is an integer (positive or negative) exponent.

The speed of the current is  7 miles per hour,

and the speed of the boat in still water is  2 miles per hour.

The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.

Given A boat travels 10 miles upstream in 2 hours. Going​ downstream, it can travel 18 miles in the same amount of time.

let the speed of the boat and current be x and y,

for downstream,

x + y = D₁/t₁

D₁ = distance traveled in downstream = 18 miles

t₁ = time taken = 2 hours

x + y = 18/2

x + y = 9 .........(1)

for upstream,

x - y = D₂/t₂

D₂ = distance traveled in upstream = 10 miles

t₂ = t₁ = time taken  = 2 hours

x - y = 10/2

x - y = 5 .......(2)

adding both equations

x + y + x - y = 9 + 5

2x = 14

x = 7 miles per hour

and x + y = 9

7 + y = 9

y = 9 - 7

y = 2 miles per hour

speed of the boat is 7 miles per hour and the speed of the current is 2 miles per hour.

Hence boat's speed is  7 miles per hour and the current speed is 2 miles per hour.

The equation -bx2 + c2x + a3 has a larger solution of x = (-c + sqrt(c2 - 4ab))/2a.

We  must first move the constants to the right side of the equation in order to find the solution to the equation

-bx2 + c2x + a3 = 0.

As a result, we have the equation -bx2 + c2x = -a3. The result is x2 - (c2/b)x = -a3/b after dividing both sides by -b. The quadratic formula can be used to resolve this quadratic equation. x = (-c + sqrt(c2 - 4ab))/2a is the equation's more complex solution. We enter the coefficient values into the quadratic formula to verify this. The broader solution is

x = (-4 + sqrt(4 - 24))/4 = (-4 + sqrt(-20))/4 = (-4 + 25)/4 = 0.55 - 1,

To find the range of a function substitute the domine values into the given function f(x).

Here we have

Give domain of  f(x) = 4x + 4; { -2, -1, 0, 1, 2}

The range of the f(x) can be calculated as follows

Take x = -2 => f(x) = 4(-2) + 4 = -8 + 4 = - 4

Take x = -1 => f(x) = 4(-1) + 4 = - 4 + 4 = 0

Take x = 0 => f(x) = 4(0) + 4 = 0 + 4 = 4

Take x = 1 => f(x) = 4(1) + 4 = 4 + 4 = 8

Take x = 2 => f(x) = 4(2) + 4 = 8 + 4 = 12

Answer: Based on the information provided, it appears that the graph represents a linear equation, which is a straight line. The equation of a straight line can be represented in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of the line, we need two points on the line. We can use the points (x1, y1) and (x2, y2) to calculate the slope of the line, m, using the formula:

m = (y2 - y1) / (x2 - x1)

Without knowing the coordinates of the points on the graph it is not possible to give the equation of the line.

To find the cost of ordering 6 pounds of mushrooms, we would substitute 6 for x in the equation of the line and solve for y.

The height of the hat is 9.0 inches.

A party hat is in the shape of a cone with dimensions shown . Therefore, the height of the cone can be found as follows:

The radius of the cone is 4.3 inches and the slanted height of the cone is 10 inches.

Therefore, Pythagoras's theorem can be used to find the height of the cone. The radius and the slanted height of the cone forms a right angle triangle.

Therefore,

10² - 4.3² = h²

h² = 100 - 18.49

h² = 81.51
