1)Gross Yearly Income = Hourly Wage × Hours per Week × Weeks in a Year

Gross Yearly Income = $15/hour × 40 hours/week × 52 weeks/year

Gross Yearly Income = $31,200

2)Gross Monthly Income = Gross Yearly Income / Months in a Year

Gross Monthly Income = $31,200 / 12 months

Gross Monthly Income ≈ $2,600

Step-by-step explanation:

In mathematics, the absolute value |x|, is the non-negative result of x without regard to its sign.

An absolute function, can never have a negative result.

By this alone, you can solve the question because the inequality is false, and therefore there are zero solutions.

Please see the attachment of f(x) = |x - 7|.

When you look at the graph, you can easily confirm that there is no value which can result in a negative y- coordinate like -2. In fact, that is the whole purpose of any absolute value or function. The result of an absolute function can never be negative.

The value for the test statistic and the p value on the test when the researcher wanted to see if different breeds of dogs will be x² = 0.9421 and 0.05 < p value < 0.10.

From the information given, the null hypothesis is that the variables have no difference while the alternative hypothesis is that they have a difference.

The degree of freedom will be:

Answer:

Step-by-step explanation:

From Khan

The exponential function that models a 15% decay is: y = (0.85)^t^(1/2)

To find the base that could be written in the blank to make the exponential function model a 15% decay, we can start by understanding the nature of exponential decay.

The general formula for exponential decay is given by:

y = A(1 - r)^t

Where:

y represents the final amount or value after time t.

A is the initial amount or value.

r is the decay rate (expressed as a decimal).

t is the time.

In this case, we want to find the decay rate (r) that corresponds to a 15% decay. A 15% decay means that the final amount is 85% of the initial amount. So, we can write the equation as:

y = A(1 - 0.15)^t

Simplifying further:

y = A(0.85)^t

Comparing this equation to the given form y = (_)t^(1/2), we see that the base in the blank must be 0.85.

Therefore, the exponential function that models a 15% decay is:

y = (0.85)^t^(1/2)

This equation represents a scenario where the initial value or amount (A) is being reduced by 15% over time (t), with the exponent of 1/2 indicating that the decay occurs at a square root rate.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The dimensions of the rectangular garden which minimize the cost is equal to 9.6ft and 14.6ft respectively.

As given in the question,

Cost of brick wall is equal to $40/ft

Cost of metal fencing is equal to $20/ft

Let 'x' and 'y' are the dimensions of the rectangular garden

Area of the rectangular garden = 142 square feet

⇒ 142 = xy

⇒x = 142/y

Costing of four side fencing 'C' = 40x + 20x + 20y + 20y

⇒ C = 60x + 40y

⇒C = 60(142/y) + 40y

⇒C = 8520/y + 40y

Differentiate with respect to y

dC/dy = -8520/ y² + 40

Put dC/dy = 0

-8520/ y² + 40 = 0

⇒y² = 8520/40

⇒y = √213

⇒ y= 14.6 ft

⇒ x= 142/14.6

     = 9.7 ft

Therefore, the dimensions of the rectangular garden with the given area which minimize the cost is equal to 14.6ft and 9.7ft.

The graph that represents the equation is:

The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

Option B is the correct answer.

We have,

The equation y = (3/2)x² - 6x represents an upward parabola since the coefficient of x² is positive.

Now,

The vertex of the parabola.

x = -b/2a,

where a and b are the coefficients of x² and x, respectively.

So,

a = 3/2 and b = -6

x = -(-6)/(2(3/2)) = 6/3 = 2.

Plugging x = 2 into the equation,

We get y = 3/2(2)² - 6(2) = -6,

so the vertex is (2, -6).

We can eliminate options A and C since their vertices are not (2, -6).

Now,

To check which of the remaining options fits the equation, we can plug in the given points and see if they satisfy the equation.

Option B gives:

When x = -1, y = 3/2(-1)² - 6(-1) = 7

When x = 0, y = 3/2(0)² - 6(0) = 0

When x = 4, y = 3/2(4)² - 6(4) = 0

When x = 5, y = 3/2(5)² - 6(5) = 7.5

So option B fits the equation, and is the graph that represents

y = (3/2)x² - 6x.

Therefore,

The graph that represents the equation is:

The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

Answer:

I think that the answer may be volume = 169.65

Step-by-step explanation:

The volume of cylinder whose radius 3m and height 6m is 169.56 cm³ ≈ 170 cm³

The volume of a cylinder is the density of the cylinder which signifies the amount of material it can carry or how much amount of any material can be immersed in it. Cylinder’s volume is given by the formula, π\(r^2h\), where r is the radius of the circular base and h is the height of the cylinder.

Here, Radius of Cylinder = 3 m.

         Height of Cylinder = 6 m.

Volume of Cylinder = πr²h

                                 = 3.14 X 3 X 3 X 6

                                 = 169.56 cm³

                                 ≈ 170 cm³

Thus, the volume of cylinder whose radius 3m and height 6m is 169.56 cm³ ≈ 170 cm³.

Explanation:

Given the function:

5y = 2x - 10

Choose points for x, such as -2, -1, 0, 1, and 2

Solve for the corresponding of each point of x for y

For x = -2

5y = 2(-2) - 10

5y = -4 - 10

5y = -14

y = -14/5 = -2.8

For x = -1

5y = 2(-1) - 10

5y = -2 - 10

5y = -12

y = -12/5 = -2.4

For x = 0

5y = 2(0) - 10

5y = 0 - 10

5y = -10

y = -10/5 = -2

For x = 1

5y = 2(1) - 10

5y = 2 - 10

5y = -8

y = -8/5 = -1.6

For x = 2

5y = 2(2) - 10

5y = 4 - 10

5y = -6

y = -6/5 = -1.2

Inputs (x): -2, -1, 0, 1, 2

Outputs (y): -2.8, -2.4, -2.0, -1.6, -1.2
