Answer:

The domain of the function in the graph is option B, 6≤k≤11.

In the given graph, the horizontal axis represents k and the vertical axis represents j. The graph shows a line segment connecting the points (6, 120) and (11, 80). The domain of a function is the set of all possible values of the independent variable (input) for which the function is defined. In this case, k is the independent variable and j is the dependent variable (output).

The line segment in the graph represents a linear function, where the value of j depends on the value of k. The function is defined only between the values of k that correspond to the endpoints of the line segment, which are k = 6 and k = 11. Therefore, the domain of the function is 6≤k≤11.

Answer:  Maria is 12 years old, Jonas is 6 years old, and Franklin is 3 years old.

Step-by-step explanation:  Let's start by assigning variables to represent the ages of Maria, Jonas, and Franklin.

Let's use the variable "M" to represent Maria's age.

Let's use the variable "J" to represent Jonas's age.

Let's use the variable "F" to represent Franklin's age.

From the problem statement, we know that:

Maria is twice the age of Jonas: M = 2J

Jonas is twice the age of Franklin: J = 2F

Franklin is 2 years less than half of Maria's age: F = 0.5M - 2

We can use these equations to solve for the ages of Maria, Jonas, and Franklin.

First, we can substitute J = 2F into the equation M = 2J to get M = 2(2F) = 4F.

Next, we can substitute this expression for M into the equation F = 0.5M - 2 to get F = 0.5(4F) - 2, which simplifies to 2F = 6 and therefore F = 3.

Now that we know Franklin's age, we can use the equation J = 2F to find Jonas's age: J = 2(3) = 6.

Finally, we can use the equation M = 2J to find Maria's age: M = 2(6) = 12.

Therefore, Maria is 12 years old, Jonas is 6 years old, and Franklin is 3 years old.

Based on an exponential model of the data, the predicted value of variable 2 when variable 1 = 2 is: A. variable 2 ≈ 128.

In order to determine an exponential equation for the line of best fit that models the data points contained in the graph (scatter plot), we would have to use a graphing calculator (Microsoft Excel).

Based on the scatter plot (see attachment) which models the relationship between the x-values (variable 1) and y-values (variable 2), an exponential equation for the line of best fit is given by

[tex]y = 137.93e^{-0.03x}[/tex]

Now, we can determine the predicted value of variable 2 when variable 1 = 2;

[tex]y(2) = 137.93e^{-0.03\times 2}\\\\y(2) = 137.93e^{-0.06}[/tex]

y(2) ≈ 128.

If the equation representing an employee's monthly earnings is y = 0.16x + 1250 where x is the monthly sales and y is the monthly earnings, the true statement is c) Employees receive 16% commission on their total monthly sales..

An equation is an algebraic statement of the equality or equivalence of mathematical expressions.

While equations use the equal symbol (=), mathematical expressions combine variables with numbers, constants, values, and mathematical operands.

Let the monthly earnings of an employee = y

Let the monthly sales = x

y = 0.16x + 1,250

Thus, from this equation, 0.16 represents 16% commission on sales, therefore, the correct option is Option C.

a) The monthly salary of an employee is $1,250.

b) The slope is 1,250 and the y-intercept is 0.16.

c) Employees receive 16% commission on their total monthly sales.

d) The monthly salary of an employee is 12.50%.

Answer:

$2,602.44

Step-by-step explanation:

To find the monthly payments and the total interest for Loan A, we can use the formula for the present value of an installment loan:

PV = PMT x [1 - (1 + r/n)^(-nt)] x (n/r)

where PV is the present value of the loan, PMT is the monthly payment, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years of the loan.

For Loan A, we have:

PV = $14,000

r = 0.051 (5.1% as a decimal)

n = 12 (monthly payments)

t = 3

Substituting these values into the formula and solving for PMT, we get:

PMT = PV / ([1 - (1 + r/n)^(-nt)] x (n/r))

= 14000 / ([1 - (1 + 0.051/12)^(-12*3)] x (12/0.051))

= $417.79

So the monthly payment for Loan A is $417.79.

To find the total interest paid over the life of the loan, we can simply multiply the monthly payment by the total number of payments and subtract the original loan amount:

Total interest = PMT x (nt) - PV

= 417.79 x (3 x 12) - 14000

= $2,602.44

Therefore, the total interest paid for Loan A is $2,602.44.

Answer:

Adeline has 60 notebooks and 4 children.

Step-by-step explanation:

Let's assume that Adeline has 'x' notebooks and 'y' children.

According to the given information, if Adeline gives 13 notebooks to each child, she will have 8 notebooks left. This can be represented by the equation:

x - 13y = 8 ...(1)

Similarly, if she gives 15 notebooks to each child, they will have zero notebooks left, which can be represented by the equation:

x - 15y = 0 ...(2)

We now have two equations with two variables. To solve for 'x' and 'y', we can use the method of elimination. Multiplying equation (1) by 15 and equation (2) by 13, we get:

15x - 195y = 120 ...(3)

13x - 195y = 0 ...(4)

Subtracting equation (4) from equation (3), we get:

2x = 120

x = 60

Substituting the value of 'x' in equation (2), we get:

60 - 15y = 0

y = 4

Therefore, Adeline has 60 notebooks and 4 children.

Answer:

a = 40°

Step-by-step explanation:

An isosceles triangle has two sides that are the same size. The angles opposite from those sides are equal (they are called base angles.) And, the three angles in a triangle add up to 180°

So,

100 + a + a = 180

combine like terms

100 + 2a = 180

subtract 100

2a = 80

divide by 2

a = 40

Answer:  the volume of the box is 31.25 cubic feet.

Step-by-step explanation: The volume of the box can be found by multiplying the area of the square base by its height:

Volume = Base Area x Height

Since the base of the box is a square with 2.5 feet wide on a side, its area can be calculated as:

Base Area = Side Length x Side Length = 2.5 ft x 2.5 ft = 6.25 sq. ft

And since the height of the box is 5 feet, the volume can be calculated as:

Volume = Base Area x Height = 6.25 sq. ft x 5 ft = 31.25 cubic feet

Therefore, the volume of the box is 31.25 cubic feet.

The possible zeros from the function would be zero.

To find all possible zeros of the polynomial f(x) = 2x³ + 3x² - 10x + 7, we can use the Rational Root Theorem.

We can test these possible zeros by plugging them into the polynomial:

f(1) = 2(1)³ + 3(1)² - 10(1) + 7 = 2

f(-1) = 2(-1)³ + 3(-1)² - 10(-1) + 7 = 12

f(7) = 2(7)³ + 3(7)² - 10(7) + 7 = 776

f(-7) = 2(-7)³ + 3(-7)² - 10(-7) + 7 = -732

f(1/2) = 2(1/2)³ + 3(1/2)² - 10(1/2) + 7 = -0.5

f(-1/2) = 2(-1/2)³ + 3(-1/2)² - 10(-1/2) + 7 = 8.5

f(7/2) = 2(7/2)³ + 3(7/2)² - 10(7/2) + 7 = 89.75

f(-7/2) = 2(-7/2)³ + 3(-7/2)² - 10(-7/2) + 7 = -83.75

None of the possible rational zeros are actual zeros of the polynomial f(x) = 2x³ + 3x² - 10x + 7.

Step-by-step explanation:

using the rules of logarithms

log x - log y = log ([tex]\frac{x}{y}[/tex] )

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

The equations which represents circles that have a diameter of 12 units and a center that lies on the y-axis are; x² + (y – 3)² = 36 and x² + (y + 8)² = 36.

Recall, the equation of a circle takes the form;

(x - h)² + (y – k)² = r² where r = radius = diameter/2 and (h, k) is the center.

Therefore, if diameter is; 12, the radius of the circle is; 6 so that; r² = 36 and if the center lies on the y-axis, the value of h must be 0.

Ultimately, the equations that satisfy the given conditions are; x² + (y – 3)² = 36 and x² + (y + 8)² = 36.

Answer: 0.2461

Step-by-step explanation:

There are 16 balls in total, and 9 of them are purple. If the first ball drawn is replaced before the second is drawn, then the number of purple balls and the number of total balls in the urn remain the same for the second draw.

The probability of drawing a purple ball on the first draw is 9/16. Since the ball is replaced, the probability of drawing a purple ball on the second draw is also 9/16.

The probability that the second ball drawn is a purple ball, given that the first ball drawn was replaced and was a green ball:

(7/16) * (9/16) = 63/256 ≈ 0.2461

To the nearest whole dollar, the antique dresser was purchased by Danielle as follows: A. purchase price: $120, advertised price: $300.

The purchase price of the antique dresser can be determined by reversing the solution from the discounted price.

The discounted price is divided by the discount factor to calculate the advertised or marked price.

Let the purchase price of the antique dresser = x

Markup = 250%

Discount = 15%

Discounted price = $255

Discount factor = 0.85 (1 - 0.15)

Marked up or advertised price = $300 ($255 ÷ 0.85)
