The required equation is g(x) = 10(3)x which is the correct answer would be an option (A).

The graph of g(x) is obtained by stretching the graph of f(x) vertically by a factor of 2.

Since the vertical stretch of a graph multiplies the y-coordinates of each point on the graph by a constant factor, the equation of g(x) must be obtained by multiplying the y-coordinate of each point on the graph of f(x) by 2.

In the given equation f(x) = 5(3)x, the y-coordinate of each point on the graph of f(x) is 5(3)x.

Thus, to stretch the graph of f(x) vertically by a factor of 2, we need to multiply this y-coordinate by 2 to get the y-coordinate of the corresponding point on the graph of g(x). This gives us the following equation for g(x):

⇒ g(x) = 2 × 5(3)x = 10(3)x

Therefore, the required equation is g(x) = 10(3)x.

Hence, He had to pay $ 18.11 for the tip on a restaurant bill.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Josiah ate dinner at a restaurant and his bill was $15.75,

He wanted to leave  15% tip,

Then He had to pay,

=15.75+15 % of 15.75

=15.75 + 0.15*15.75

Answer:

Interpretation of the slope: For students at this school, the predicted GPA decreases by 0.005 for each additional text message sent OR the GPA decreases by 0.005, on average, for each additional text message sent.

Interpretation of intercept: The model predicts that students at this school who send no text messages have, on average, a GPA of 3.8.

Step-by-step explanation:

The purpose of this task is to assess the ability to interpret the slope and intercept of the line of best fit in context. There are two common errors that students make when interpreting the slope. Students may not make it clear that the slope is the predicted change (not necessarily an actual change) in GPA associated with an increase of 1 in the number of text messages sent. They also often do not communicate that the slope describes the change

You might want to point out that it is not always reasonable to interpret the intercept as the predicted y value when x = 0, as this often involves extrapolation far beyond the range of the x values in the data set. In this example, however, it is appropriate because there are observations with x = 0 in the data set.

You can also point out that the interpretation of the slope and intercept represents a generalization from the sample of 52 students to the population of all students at the school. This is appropriate because the sample was a random sample of students from the school.

Although this task is short and looks simple, some of the points brought out in this task are subtle. It might be a good strategy to engage in a whole class discussion of the correct interpretations.

We have to given that,

A composite figure is shown.

In first part,

For second part,

Lenght (L) = 7m

Width (w) = 16 - 9 = 7m

Step-by-step explanation:

The number of hydrogen atoms present in the sculpture of earth if the mass of earth is 829 kg is 4.145 × 10²⁹.

Given that,

Mass of the sculpture of the earth = 829 kg

We know that,

Mass of an hydrogen atom = 2 × 10⁻²⁷ kg

Number of hydrogen atoms = Mass of earth / Mass of hydrogen atom

                                              = 829 / 2 × 10⁻²⁷

                                              = 414.5 × 10²⁷

                                              = 4.145 × 10²⁹

The equation for a transformed cosine wave with the following properties is  y = 3cos2x + 4

An equation for a transformed cosine wave with the following properties can be written in the form:

y = A× cos(B(x - C)) + D

Where:

A = amplitude (positive value)

C = phase shift (horizontal shift of the wave)

D = vertical shift (shift of the wave up or down)

Here we have

Amplitude = 3

Period = π

Horizontal shift = None

Vertical shift  = 4 units  up  

As we know Period P = 2π/B

From the data => 2π/B = π

=> B = 2  

Hence,

Equation for a transformed cosine wave, y = 3 × cos(2(x - 0)) + 4

=> y = 3 × cos(2(x )) + 4

=> y = 3cos2x + 4  

Therefore,

The equation for a transformed cosine wave with the following properties is  y = 3cos2x + 4

Step-by-step explanation:

So we have the function:

\(f(x)=4x^2-6\)

And we want to find all x such that f(x) is 106. So, substitute 106 for f(x):

\(106=4x^2-6\)

Add 6 to both sides:

\(112=4x^2\)

Divide both sides by 4:

\(x^2=28\)

Take the square root of both sides:

\(x=\pm\sqrt{28}\)

Simplify the square root:

\(x=\pm\sqrt{28}=\pm\sqrt{4\cdot 7}=\pm2\sqrt7\)

The area of a rectangle is the total space it would cover in a two-dimensional plane. Thus, the required answers are:

i. The area of the rectangle is 31.1 \(km^{2}\).

ii. There are 18.9 liters of paint in the 5-gallon bucket.

Plane figures are bounded by straight sides. Thus examples are triangle, rectangle, square, trapezium, rhombus, etc.

A rectangle is a plane shape that has four sides. In this figure, two opposite sides have equal lengths.

The area of a rectangle = length x width

So in the given question, we have:

1) 1 mile = 1.60934 Kilometres

Thus;

2 miles = 3.21869 km

6 miles = 9.65606 km

Area of the given rectangle = 3.21869 x 9.65606

                                              = 31.0799

The area of the rectangle is 31.1 \(km^{2}\).

2) Given a 5-gallon bucket, then:

1 gallon = 3.78541 liters

So that;

5 gallons = 18.9271 liters

               = 18.9 liters

Thus there are 18.9 liters of paint in the 5-gallon bucket.

The slopes of the curve's tangent line at point (1, 0) are  fx(1, 0) = -2√3 and fy(1, 0) = 0.

fx(1, 0) = -2sqrt(3)

We take the partial derivative of f(x, y) with regard to x to determine fx:

fx(1, 0) = ∂f/∂x = -2x/√(4-x2-4y2)

When x = 1 and y = 0 are substituted into the partial derivative equation:

fx(1, 0) = -2(1)/√(4-12)

fx(1, 0) = -2√3

fy (1,0) = 0

To calculate fy, evaluate the partial derivative for f(x, y) with regard to y:

fy(1, 0) = ∂f/∂y = -8y/√(4-x2-4y2)

Moreover x = 1 and y = 0, the partial derivative calculation has now become: fy(1, 0) = -8(0)/√(4-12)

fy(1, 0) = 0

A slopes at (1, 0) are fx(1, 0) = -2√3 and fy(1, 0) = 0. This indicates that the tangent line to the curve at (1, 0) has a negative slope and a zero vertical component.

By the triangle inequality theorem, the sum of the lengths of the two shorter sides needs to be greater than the length of the longest side.

Answer:

A).4m^(+5)

B).2m^ (+7)

Step-by-step explanation:

First let me convert the expression to words for easy simplification and evaluation.

2m squared times 2m to the power 3.

= 2m² * 2m³

m to the power 4 times 2m to the power 3

= m⁴ * 2m³

So to evaluate.

We just multiply and get our answer.

For 2m² * 2m³

= (2*2)(m²*m³)

= 4(m(²+³))

= 4m^(+5)

For m⁴ * 2m³

= 2(m⁴*m³)

= 2m(⁴+³)

= 2m^ (+7)
