So, y is a system two distinct exponential functions.

The function on the bottom is a cubic function with a y-intercept of -3, and the full dot means that point is included in the domain.

y = x^3 - 3, x ≤ 2

The other function is a quadratic function with a currently unknown y-intercept. The hollow dot on point 2 means that the point is not included in the domain of the function.

y = x^2 + b, x > 2

So, given that there is only one option that matches this, even with the unknown b value, we know:

[tex]y = \left \{ {{x^3 - 3, x\leq 2} \atop {x^2 + 6, x > 2}} \right.[/tex]

To find the other factor of the polynomial

We need to find two integers which multiplication gives 36 and addition is -13.

This integers would be -9 and -4, then we have

now we factor the right term using common factors:

Hence:

Therefore, the other binomial we are looking for is (p-4).

We first need to calculate the slope of the line.

m=(0-0)/(5-0)=0 since the slope is equal to zero we have that the line is horizontal.Then the equation is

the equation is y=0

Four points that are contained in the inverse function include the following:

An inverse function refers to a type of function that is obtained by reversing a mathematical operation in a given function (f(x)).

In order to determine the inverse of the given function, we would interchange both the input value (x) and output value (y) as follows:

y = 2x - 4

x = 2y - 4

Subtracting 4 from both sides, we have:

x + 4 = 2y - 4 + 4

2y = x + 4

Dividing both sides by 2, we have:

y = (x + 4)/2

y = x/2 + 4

When x = 0, we have:

y = x/2 + 4

y = 0/2 + 4

y = 4

Point = (0, 4).

When x = 1, we have:

y = x/2 + 4

y = 1/2 + 4

y = 4.5

Point = (1, 4.5).

When x = 2, we have:

y = x/2 + 4

y = 2/2 + 4

y = 5

Point = (2, 5).

When x = 4, we have:

y = 4/2 + 4

y = 0/2 + 4

y = 6

Point = (4, 6).

The piecewise function for the graph.

Solution:

From the graph, it is clear that when x is less than -1, the graph passes through (-1, -3) and (-2, -5).

It is known that the equation of a line passes through two points is given by:

So, the equation of line passing through (-1, -3) and (-2, -5) is:

So, the first drop down is "2x - 1", and second drop down is "x is less than or equal to -1".

Now, the graph passes through (1, 5) and (2, 6). So, the equation of the line is:

So, the third drop down menu is "x + 4" and the fourth drop down menu is "x is greater than or equal to 1".

ANSWER and EXPLANATION

We are given x = 2.

To plot the graph of x = 2, it is important to note that the value of x does not change for this equation.

x is always 2 regardless of the value of y.

This means that we are going to plot a straight line that will straight up (and down as well) at x = 2.

The graph therefore is:

For 6 sandwiches and 3 dozen cookies, the total time taken by Brenda would be 33 minutes.

Given is Brenda who must make at least 6 sandwiches and at least 3 dozen cookies. It takes her 4 minutes to make a sandwich, and 45 minutes to make a dozen cookies.

If she makes [x] sandwiches and [y] dozen cookies, then the total time she would take to make them can be written as -

t = 4x + 3y

For 6 sandwiches and 3 dozen cookies, we can write -

t(6, 3) = 4 x 6 + 3 x 3 = 24 + 9 = 33 minutes

t(6, 3) = 33 minutes

Therefore, for 6 sandwiches and 3 dozen cookies, the total time taken by Brenda would be 33 minutes.

The binomial probability of x successes is 0.302.

Since we are dealing with a binomial probability experiment. We are going to use the binomial distribution formula for determining the probability of x successes:

P(x = r) = nCr . p^r . q^n-r

Given: n=10, p=0.2, x=2

The failures can be calculated using q = 1 - p = 1 - 0.2 = 0.8

P(x = 2) =  10C2 x 0.2²  x 0.8¹⁰⁻²

            = 10!/(10-2)! 2!  x 0.2² x 0.8⁸

            = 10!/(8!2!)  x 0.2² x 0.8^8

            = 10x9x8!/(8!2!)  x 0.2² x 0.8⁸

            = 45 x 0.2² x 0.8⁸

           = 0.302

Therefore, the probability of x successes in 10 trials is 0.302

Answer:

The equation of the line k is

Explanation:

Given that k is perpendicular to line m, defined as:

y = 3x - 1

the slope of k is the negative reciprocal of the slope of line m.

The slope of m is 3

The negative reciprocal of m is -1/3 (this is the slope of k)

Therefore, k is in the form

Since this line passes through the point (x, y) = (-4, 3), we can use this to obtain the value for the y-intercept, b

Solving for b by subtracting 4/3 from both sides

A quarter is 25 cents = 25/100 = $0.25

Let N represent the number of nickels

Let D represent the number of dimes

Let Q represent the number of quarters

Jacob opened his piggy bank and found Nickels, Dimes, and Quarters totaling 81 coins. It means that

N + D + Q = 81

The total value of the coins was $7.90. It means that

0.05N + 0.1D + 0.25Q = 7.9

The number of Dimes was 7 less than triple the number of Quarters. It means that

D = 3Q - 7

The system of equations is

N + D + Q = 81

0.05N + 0.1D + 0.25Q = 7.9

The Solution:

Given that a coat costs $99.99 and the sales tax is $75.

We are required to find the actual sales tax and the total cost of the coat.

Step 1:

We shall find the sales tax.

Thus, the sales tax is $7.00 or 700 cents.

Step 2:

We shall find the total cost of the coat.

The total cost of the coat is the sum of the coat's cost and the sales tax.

Therefore, the correct answers are:

Sales tax =$7.00 or 700 cents.

Total cost = $106.99 or 10699 cents..99 or 10699 cents.

Why can the Vertical Angle Theorem NEVER be used to prove two triangles are congruent?

The Vertical angle theorem states that vertical angles are always congruent.

We can't use this to proof congruence between two triangles because this theorem not provide enough evidence to obtain the SSS, ASA, SAS, AAS, HHL. For this reason is not appropiate to use it for this case.

In order to calculate the area of the triangle, given the length of its three sides, we can use Heron's formula:

Where p is the semi-perimeter.

So, calculating the value of p and then the area of the triangle, we have:

Rounding to the nearest square foot, the area is 170 ft².

The classification of each cost item as a differential cost, a sunk cost, an opportunity cost, or None, is as follows:

1. Cost of the old X-ray machine                                  Sunk cost

2. The salary of the head of the Radiology Dept.      None

3. The salary of the head of the Laboratory Dept.     None

4. Cost of the new color laser printer                          Differential cost

5. Rent on the space occupied by Radiology             None

6. The cost of maintaining the old machine               Differential cost

7. Benefits from a new DNA analyzer                         Opportunity cost

8. Cost of electricity to run the X-ray machines         Differential cost

9. Cost of X-ray film used in the old machine            Sunk cost

A differential cost is a cost that arises as the cost difference between two alternatives.

A sunk cost is an irrelevant cost in managerial decisions because it has been incurred already and future decisions cannot overturn it.

An opportunity cost is a benefit that is lost when an alternative is not chosen.

Thus, the above cost classifications depend on the decision to replace the old X-ray machine with a new machine (new X-ray or new DNA analyzer).

Let's find the area under the standard normal curve.

Let's find the score using the standard normal distribution table:

NORMSDIST(1.40) = 0.9192

NORMSDIST(2.13) = 0.9834

To find the area between them, we have:
