Gary's average speed is approximately 44.4 mph. This is found by dividing the total distance traveled (800 miles) by the total time taken (18 hours) and rounding to the nearest tenth.

To calculate Gary's average speed, we need to use the formula

Average speed = Total distance ÷ Total time

In this case, the total distance is 800 miles, and the total time is 18 hours. So we can plug these values into the formula and simplify

Average speed = 800 miles ÷ 18 hours

Average speed = 44.444444... miles per hour

Rounding to the nearest tenth, we get

Average speed ≈ 44.4 miles per hour

Therefore, Gary's average speed during his 800-mile trip was approximately 44.4 miles per hour.

The simplified form of the polynomial (4x² - 3x + 10) + (-9x² + 4x - 6) is -5x² + x + 4.

The constant term is the term without a variable, in this case, 4 is the constant term.

What is polynomial?

A polynomial is a mathematical expression that consists of variables and coefficients

To simplify the polynomial, we need to combine like terms. We have:

(4x² - 3x + 10) + (-9x² + 4x - 6)

= 4x² - 3x + 10 - 9x² + 4x - 6 (distributing the negative sign)

= (4x² - 9x²) + (-3x + 4x) + (10 - 6) (grouping like terms)

= -5x² + x + 4 (combining like terms)

Therefore, the simplified form of the polynomial (4x² - 3x + 10) + (-9x² + 4x - 6) is -5x² + x + 4.

In the polynomial -5x² + x + 4, the degree is 2, the leading coefficient is -5, and the constant term is 4.

The degree of a polynomial is the highest power of the variable in the polynomial, in this case, x² has the highest power of 2.

The leading coefficient is the coefficient of the term with the highest power of the variable, in this case, -5 is the coefficient of the x² term, so it is the leading coefficient.

The constant term is the term without a variable, in this case, 4 is the constant term.

-1^(1/2) (which is equal to -1)

1^(1/8) (which is equal to 1)

1^(1/2) (which is equal to 1)

The soft drink vendor's maximum profit per day is $5250, and he must sell 1500 cans of soda pop to reach the maximum profit.

To find the maximum profit per day for the soft drink vendor, we need to use the formula P(x) = 0.001x^2 + 3x + 1800, where x is the number of cans of soda pop sold in one day.

To find the maximum profit, we need to find the vertex of the parabola represented by the profit function. The x-coordinate of the vertex is given by -b/2a, where a = 0.001 and b = 3. Plugging in these values, we get x = -3/(2*0.001) = -1500.

Since the soft drink vendor cannot sell a negative number of cans, we know that the maximum profit occurs at the closest whole number to x = -1500, which is x = 1500.

To find the maximum profit per day, we can plug in x = 1500 into the profit function:

P(1500) = 0.001(1500)^2 + 3(1500) + 1800 = $5250

Therefore, the soft drink vendor's maximum profit per day is $5250, and he must sell 1500 cans of soda pop to reach the maximum profit.

To find the maximum profit per day and the number of cans needed to reach that profit, we'll first need to find the critical point of the given quadratic profit function, P(x) = -0.001x^2 + 3x - 1800.

Step 1: Find the derivative of P(x) with respect to x. This will give us the rate of change of profit as the number of cans sold changes.

P'(x) = -0.002x + 3

Step 2: Set the derivative equal to zero and solve for x. This will give us the critical point where the maximum profit occurs.

-0.002x + 3 = 0

x = 1500 cans

Step 3: Substitute the critical point (x = 1500) back into the profit function P(x) to find the maximum profit.

P(1500) = -0.001(1500)^2 + 3(1500) - 1800

P(1500) = $600

So, the maximum profit per day is $600, and the soft drink vendor must sell 1500 cans to reach the maximum profit.

The maximum profit per day is $4800, and the vendor must sell 1500 cans of soda pop to reach this maximum profit.

The profit function for the soft drink vendor is given by:

P(x) = [tex]0.001x^2 + 3x + 1800[/tex]

To find the maximum profit, we need to find the vertex of the parabola represented by this function. The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

where a = 0.001 and b = 3. Substituting these values, we get:

x = -3 / (2 * 0.001) = -1500

Since the value of x cannot be negative in this context, we know that the maximum profit occurs at x = 1500. To find the maximum profit, we substitute this value of x into the profit function:

P(1500) =[tex]0.001(1500)^2 + 3(1500) + 1800 = $4800[/tex]

Therefore, the maximum profit per day is $4800, and the vendor must sell 1500 cans of soda pop to reach this maximum profit.

As a result, choice B adequately justifies why a graph that fails the vertical line test cannot be used to represent a function.

A function in mathematics is a rule or association that gives each input value a distinct output value. A function, then, is a collection of ordered pairs, each pair consisting of an input value (also known as an argument or predictor variable) and the control signal value (also known as the value or dependent variable). The output value for each given input value can be found using the formula or graph of a function.

Option B provides the justification for why a graph that fails the vertical line test cannot be used to represent a function: One x-value is coupled with numerous y-values on a vertical line.

A vertical line is not a function since a function cannot have one x-value associated with multiple separate y-values.

To ascertain whether a graph accurately depicts a function, use the vertical line test.

Each vertical line that crosses the graph more than once has an x value and several y values, which is against the definition of a function.

The standard error of the mean for a sample of size 8 and population mean 436 is equals to the 36.42.

The standard error of the mean, or usually say standard error, shows how different the population mean from a sample mean. We have a population with population mean, [tex]\mu[/tex] = 436

Standard deviations for population, [tex] \sigma[/tex] = 103

Sample size, n = 8

We have to determine the value of standard error of the mean. SEM is calculated simply as dividing the standard deviation by the square root of the sample size, n. Mathematically,

[tex]SE = \frac{ \sigma}{\sqrt n}[/tex]

Substitues all known values in above formula, [tex]= \frac{ 103}{\sqrt 8}[/tex]

To find out which class had the greatest fraction of students who preferred vanilla ice cream, we need to compare the ratios of students who preferred vanilla to the total number of students in each class.

For second period class:

Number of students who preferred vanilla = 725

Total number of students = unknown

Ratio of students who preferred vanilla to total number of students = unknown/unknown = undefined

For fourth period class:

Number of students who preferred vanilla = 8

Total number of students = 27

Ratio of students who preferred vanilla to total number of students = 8/27

For sixth period class:

Number of students who preferred vanilla = 30% of total number of students

Total number of students = unknown

Ratio of students who preferred vanilla to total number of students = 0.3*unknown/unknown = 0.3

Therefore, the fourth period class had the greatest fraction of students who preferred vanilla ice cream, with a ratio of 8/27.

The number of heart cakes that were sold at the cake sale was 28

According to the question,

Cost of circular-shaped cake = $7

Cost of heart shaped cake = $5

Total sale = $238

Let the number of circular cakes shaped be x

Since the number of heart cakes was sold twice as many as the circular cake, the number of heart cakes will be 2x

Cost of x circular-shaped cake = $7 * x

Cost of 2x heart shaped cake = $5 * 2x

Total sale = Cost of x circular cake + Cost of 2x heart cake

Thus, we get the following equation,

238 = 7x + 10x

238 = 17x

x = 14

Thus, the number of heart cakes sold was 2x that is 28.

Situation (A) "$400 deposited in a savings account earning 3% yearly compound interest" would yield us the highest amount in the account.

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.  

The interest you earn on interest is known as compound interest.

Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year.

You will wind up with $110.25 at the conclusion of the second year.

So, we know that anytime compound interest will make us more money than simple interest so options (C) and (D) would be wrong.

So, in option (B) we deposit $200 which is compounded for 2 years at 5%.

In option (A) we deposit $400 which is compounded at the rate of 3% and time is not given so we will assume that it will keep compounding for years and hence it will make us the most amount of money.

The expression -20 + 18.5u, when u is 0.6, in a decimal or whole number is equal to -8.9.

To evaluate the expression -20 + 18.5u when u = 0.6, we simply substitute 0.6 in place of u and simplify using the order of operations (PEMDAS).

-20 + 18.5u = -20 + 18.5(0.6) (substitute 0.6 for u)

-20 + 11.1 = -8.9 (simplify using multiplication first and then addition/subtraction)

Therefore, the value of the expression when u = 0.6 is -8.9.

The order of operations is a set of rules that dictate the order in which mathematical operations should be performed to avoid ambiguity and ensure that calculations are carried out correctly. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (performed from left to right), and Addition and Subtraction (also performed from left to right).

In this case, we first multiply 18.5 and 0.6, giving us 11.1. Then, we subtract 20 from 11.1, resulting in -8.9.
