Answer 1

Answer:

A. y = -250x + 3750

B. $2125

Step-by-step explanation:

A.

(5, 2500), (7, 2000)

(x₁, y₁)          (x₂, y₂)

          y₂ - y₁            2000 - 2500        -500

m = ----------------- = ---------------------- = ---------- = -250

          x₂ - x₁                  7 - 5                    2

y - y₁ = m(x - x₁)

y - 2500 = -250(x - 5)

y - 2500 = -250x + 1250

   +2500               +2500

-------------------------------------

y = -250x + 3750

B.

y = -250x + 3750

y = -250(6.50) + 3750

y = -1625 + 3750

y = 2125

(6.50, 2125)

I hope this helps!

Which of the following functions is graphed below?

Answers

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:

find the measures of the angles of a right triangle where one of the acute angles is *3.5* times the other

Answers

Lets draw a picture of our problem:

where x denotes the measure of the base angle.

Since interior angles of any triangle add up to 180, we have

[tex]x+3.5x+90=180[/tex]

which gives

[tex]4.5x+90=180[/tex]

By subtracting 90 to both sides, we have

[tex]\begin{gathered} 4.5x=180-90 \\ 4.5x=90 \end{gathered}[/tex]

Finally, by dividing both sides by 4.5, we get

Which statements about the graph of the exponential function f(x) are TRUE?The x-intercept is 1.The y-intercept is 3.The asymptote is y = -3The range is all real numbers greater than -3The domain is all real numbers.f(x) is positive for all x-values greater than 1As x increases, f(x) approaches, but never reaches, -3.

Answers

1 The x-intercept is the value of x where the graph intersects the x-axis. The graph crosses the x-axis at x = 1. This statement is true.

2 The y-intercept is the value of y where the graph intersects the y-axis. The graph crosses the y-axis at y = -2. This statement is false.

3 The horizontal asymptote is the value of y to which the graph approaches but never reaches. This value seems to be y = -3, thus this statement is true.

4 The range is the set of values of y where the function exists. The graph exists only for values of y greater than -3. This statement is true.

5 We can give x any real value and the function exists, i.e., any vertical line would eventually intersect the graph. This statement is true.

To find the domain of a function when we are given the graph, we use the vertical line test. This consists of drawing an imaginary vertical line throughout the x-axis. If the line intersects the graph, that value of x is part of the domain.

This imaginary exercise gives us the centainty that there is no value of x that won't intercept the graph, thus the domain is the set of all the real values.

6 We can see the graph is positive exactly when the function has its x-intercept, thus This statement is true.

7 As x increases, y goes to infinity. The value of -3 is not a number where f(x) approaches when x increases, but when x decreases. This statement is false.

The rational number - 91 / 200 is a number between the decimal numbers - 0.45 and - 0.46.

How to determine a rational number between two decimal numbers

In this problem we find two decimal numbers, of which we need to find a rational number between these numbers. Please notice that the decimal numbers are also rational numbers. First, we transform each decimal number into rational numbers:

- 0.45 = - 45 / 100

- 0.46 = - 46 / 100

Second, find a possible rational number between the two ends by the midpoint formula:

x = (1 / 2) · (- 45 / 100) + (1 / 2) · (- 46 / 100)

x = - 45 / 200 - 46 / 200

x = - 91 / 200

Then, the rational number - 91 / 200 is a number between - 0.45 and - 0.46.

how do I solve (4w+3x+5)-(4w-3x+2)

Answers

Answer:

6x + 3

Explanation:

To solve the initial expression, we need to write it without the parenthesis as:

( 4w + 3x + 5 ) - ( 4w - 3x + 2)

4w + 3x + 5 - 4w + 3x - 2

Then, we need to identify the like terms as:

4w and -4w are like terms

3x and 3x are like terms

5 and -2 are like terms

Now, we can organize the terms as:

4w - 4w + 3x + 3x + 5 - 2

Adding like terms, we get:

(4w - 4w) + (3x + 3x) + (5 - 2)

0 + 6x + 3

6x + 3

Therefore, the answer is 6x + 3

What are the mean and median?

A dot plot is a graph used to represent a dataset. A dot plot is made up of a number line and dots.  The dots in the dot plot represent the frequency of the data. The greater the frequency of a data, the greater the number of dots.

Mean is the average of a dataset. It is determined by adding all the numbers in the dataset together and dividing it by the total numbers in the dataset.

Mean = sum of numbers / total numbers in the dataset

Mean of the 5th grade students = ( 1 + 1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 4 + 5 + 5 + 5 + 5 + 5 + 6 + 6 + 6 + 6 + 6 + 7 + 7 + 8 + 8 ) / 24

83 / 24 = 3.46

Median is the number that is in the middle of a dataset.

Median = (n + 1) / 2

Median of the 5th grade students = (24 + 1) / 2 = 12.5 terms = 5

Median of the 7th grade students = (24 + 1) / 2 = 12.5 term = (3 + 4) / 2 = 3.5.

A rectangular board is 1200 millimeters long and 900 millimeters wide what is the area of the board in square meters? do not round your answer

Answers

Answer: Area of the rectangular board is 1.08 square meters

The length of the rectangular board = 1200 milimeters

The width of the rectangular board = 900 milimeters

Area of a rectangle = Length x width

Firstly, we need to convert the milimeter to meters

1000mm = 1m

1200mm = xm

Cross multiply

x * 1000 = 1200 x 1

1000x = 1200

Divide both sides by 1000

x = 1200/100

x = 1.2 meters

For the width

1000mm = 1m

900mm = xm

cross multiply

1000 * x = 900 * 1

1000x = 900

Divide both sides by 1000

x = 900/1000

x = 0.9m

Length = 1.2 meters

Width = 0.9 meter

Area = length x width

Area = 1.2 x 0.9

Area = 1.08 square meters

In 1980 approximately 4,825 million metric tons of carbon dioxide emissions were recorded for the United States. That number rose to approximately 6,000 million metric tons in the year 2005. Here you have measurements of carbon dioxide emissions for two moments in time. If you treat this information as two ordered pairs (x, y), you can use those two points to create a linear equation that helps you make predictions about the future of carbon dioxide emissions!A) Organize the measurements into ordered pairs. B) Find the slope,C) Set up an equation in point-slope form,D) Show the equation in slope-intercept form,E) Predict emissions for the year 2020,

Answers

ANSWER and EXPLANATION

A) To organize the measurements in ordered pairs implies that we want to put them in the form:

[tex](x_1,y_1);(x_2,y_2)[/tex]

Therefore, the measurements in ordered pairs are:

[tex]\begin{gathered} (1980,4825) \\ (2005,6000) \end{gathered}[/tex]

Note: 4825 and 6000 are in millions (10⁶) of metric tons

B) To find the slope, apply the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, the slope is:

[tex]\begin{gathered} m=\frac{6000-4825}{2005-1980} \\ m=\frac{1175}{25} \\ m=47\text{ million metric tons per year} \end{gathered}[/tex]

C) To find the in point-slope form, we apply the formula:

[tex]y-y_1=m(x-x_1)_{}[/tex]

Therefore, we have:

[tex]y-4825=47(x-1980)[/tex]

Note: the unit is in million metric tons

D) To show the equation in point-slope form, we have to put it in the form:

[tex]y=mx+b[/tex]

To do that, simplify the point-slope form of the equation:

[tex]\begin{gathered} y-4825=47(x-1980) \\ y=47x-93060+4825 \\ y=47x-88235 \end{gathered}[/tex]

E) To predict the emissions for the year 2020, substitute 2020 for x in the equation above:

[tex]\begin{gathered} y=47(2020)-88235 \\ y=94940-88235 \\ y=6705\text{ million metric tons} \end{gathered}[/tex]

That is the prediction for the year 2020.

What is the product of 3√6 and 5√12 in simplest radical form?

Answers

In order to calculate and simplify this product, we need to use the following properties:

[tex]\begin{gathered} \sqrt[]{a}\cdot\sqrt[]{b}=\sqrt[]{a\cdot b} \\ \sqrt[c]{a^b}=a\sqrt[c]{a^{b-c}} \end{gathered}[/tex]

So we have that:

[tex]\begin{gathered} 3\sqrt[]{6}\cdot5\sqrt[]{12} \\ =(3\cdot5)\cdot(\sqrt[]{6}\cdot\sqrt[]{2\cdot6}) \\ =15\cdot\sqrt[]{2\cdot6^2} \\ =15\cdot6\cdot\sqrt[]{2} \\ =90\sqrt[]{2} \end{gathered}[/tex]

So the result in the simplest radical form is 90√2.

I need help solving this and figuring out the plotting points.

If f(x) = sin(x ^ 5) , find f^ prime (x)

Answers

Solution

Step 1

Write the function.

[tex]f(x)\text{ = sin\lparen x}^5)[/tex]

Step 2

Use the chain rule to find f'(x)

[tex]\begin{gathered} f^{\prime}(x)\text{ = }\frac{df}{du}\times\frac{du}{dx} \\ \\ u\text{ = x}^5 \\ \\ \frac{du}{dx}\text{ = 5x}^4 \\ f(x)\text{ = sinu} \\ \\ \frac{df}{du}\text{ = cosu} \end{gathered}[/tex]

Step 3

[tex]\begin{gathered} f^{\prime}(x)\text{ = 5x}^4\text{ }\times\text{ cosu} \\ \\ f^{\prime}(x)\text{ = 5x}^4cos(x^5) \end{gathered}[/tex]

Step 4

Substitute x = 4 to find f'(4).

[tex]\begin{gathered} f^{\prime}(4)\text{ = 5}\times4^4\times cos(4^5) \\ \\ f^{\prime}(4)=\text{ 1280}\times cos1024 \\ \\ f^{\prime}(x)\text{ = 715.8} \end{gathered}[/tex]
