The proof of trigonometric identity (sin(x) + tan(x))/sin(x) = 1 +secx is given below.

The given trigonometric identity is,

(sin(x) + tan(x))/sin(x).

We know that tan(x) = sin(x)/cos(x), so we can substitute that in:

sin(x)/ sin(x) + sin(x)/cos(x) / sin(x)

We can simplify the fraction in the numerator:

sin(x)/ sin(x) + sin(x)/sin(x)cos(x)

We know that sin(x)/sin(x) = 1, so we can simplify further:

1+ 1/cos(x)

We know that 1/cos(x) = sec(x), so we can substitute that in:

1 + sec(x).

Now we have the same expression as the right-hand side of the identity, so we have proven that:

sin(x) + tan(x)/sin(x) = 1 + sec(x)

Therefore, (sin(x) + tan(x))/sin(x) = 1 +secx.

Answer:

$66.24

Step-by-step explanation:

The area of Vince's porch is:

8 feet x 12 feet = 96 square feet

To find the cost of the stain, we need to multiply the area of the porch by the cost per square foot:

96 square feet x $0.69 per square foot = $66.24

So it will cost $66.24 to buy enough stain for the whole porch.

Answer:

720.33 square inches.

Step-by-step explanation:

To find the amount of leather needed to create the travel case, you need to find the surface area of the cylinder. The surface area of a cylinder is given by the formula:

SA=2πr2+2πrh

where r is the radius of the base and h is the height of the cylinder. In this case, the radius is half of the diameter, so r = 17/2 = 8.5 inches. The height is given as 5 inches. Using π = 3.14, we can plug in these values and get:

SA=2×3.14×8.52+2×3.14×8.5×5

SA=452.38+267.95

SA=720.33

Therefore, the amount of leather needed is approximately 720.33 square inches. The closest answer is C. 720.63 square inches.

Answer:

720.63 square inches

To find the surface area of the cylindrical travel case, we need to add the areas of the two circular bases and the lateral surface area.

The diameter of the circular bases is given as 17 inches, so the radius is 17/2 = 8.5 inches. Using the formula for the area of a circle, we can find the area of one base:

Area of one base = πr^2 = 3.14 x 8.5^2 = 226.96 square inches

Since there are two circular bases, the total area of both bases is:

Total area of both bases = 2 x 226.96 = 453.92 square inches

The lateral surface area is a rectangle with height 5 inches and length equal to the circumference of the circular base. We can find the circumference using the formula:

Circumference = 2πr = 2 x 3.14 x 8.5 = 53.38 inches

So, the lateral surface area is:

Lateral surface area = height x circumference = 5 x 53.38 = 266.9 square inches

Therefore, the total surface area of the cylindrical travel case is:

Total surface area = 453.92 + 266.9 = 720.82 square inches (rounded to two decimal places)

So, the answer is approximately 720.63 square inches (rounded to two decimal places).

g(x) is a translation of f(x), and it can be written as:

g(x) = f(x + 2)

So f(x) is the graphed function and g(x) is the one in the table. We can see that the slopes of both functions are 2, so there is no change in the slope nor any type of reflection.

This means that we have a translation.

Now, comparing values:

f(0) = 1   and g(0) =5

f(1) = 3   and g(1) = 7

and so on.

in any of the values we can see that g(x) is 4 units above f(x), then there are two possible transformations:

g(x) = f(x) + 4

g(x) = f(x + 2)

(The +2 in the argument is equivalent because of the slope of 2, when we take that product we will get a 4)

Thus the correct option is the second one.

To show that dy/dx = 1 - x·ln(x)/x·e^x, we shall first find the derivative of y with respect to x using the chain rule and the quotient rule.

According to the Quotient Rule, the derivative of a quotient is the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the square of the denominator.

Given the equation: y = ln(x)/e^x

First, apply the quotient rule to differentiate y = ln(x)/e^x

dy/dx = [(e^x)(d/dx)(ln(x)) - (ln(x))(d/dx)(e^x)] / (e^x)^2

Next, differentiate ln(x) using the chain rule

(d/dx)(ln(x)) = 1/x

Next, differentiate e^x using the chain rule

(d/dx)(e^x) = e^x

Then, substitute the derivatives of ln(x) and e^x back into the quotient rule expression

dy/dx = [(e^x)(1/x) - (ln(x))(e^x)] / (e^x)^2

Simplify the expression:

dy/dx = (e^x/x - ln(x)e^x) / e^(2x)

Next, multiply the numerator and denominator by x

dy/dx = (xe^x/x^2 - ln(x)e^x/x) / (xe^(2x)/x^2)

Then, simplify the expression

dy/dx = (e^x/x - ln(x)e^x/x) / (xe^(2x)/x^2)

And multiply the numerator and denominator by x^2

dy/dx = (xe^x - xln(x)e^x) / (xe^(2x))

Next, factor out e^x from the numerator

dy/dx = e^x (x - xln(x)) / (xe^(2x))

And simplify the numerator

dy/dx = e^x (x(1 - ln(x))) / (xe^(2x))

Next, simplify further

dy/dx = (x - xln(x)) / (xe^(x))

Finally, rearrange the terms

dy/dx = 1 - xln(x) / xe^(x)

Therefore, the derivative of y with respect to x is given by dy/dx = 1 - xln(x)/xe^(x).

The p-value for this test is 0.012, which is the probability of observing a sample mean as extreme as 380 (or more extreme) if the null hypothesis were true.

If the significance level of the test was α = 0.05, for example, we would reject the null hypothesis since the p-value (0.012) is less than the significance level.

To find the p-value for this test, we first need to determine the appropriate test statistic. Since we do not know the population standard deviation, we will use a t-test. The test statistic is calculated as:

t = (X - μ) / (s / √n)

Where X is the sample mean, μ is the null hypothesis population mean, s is the sample standard deviation, and n is the sample size.

In this case, the null hypothesis might be that μ = 400 (for example, if we were testing whether the mean weight of a certain type of fruit was 400 grams). Using the given sample information, we can calculate the t statistic as:

t = (380 - 400) / (39 / √18) = -2.82

Next, we need to find the corresponding p-value from the t-distribution table. Looking at the table with 17 degrees of freedom (since n - 1 = 18 - 1 = 17), we find that the p-value for a two-tailed test with a t-value of -2.82 is approximately 0.012.

Answer: $1.74 worth of coins

Step-by-step explanation:

Let's say Tom throws x amount of money in coins on the table. Then Joe throws twice as much, which is 2x.

The total value of coins on the table is $5.22, so we can write an equation:

x + 2x = 5.22

Simplifying the equation, we get:

3x = 5.22

Dividing both sides by 3, we get:

x = 1.74

Therefore, Tom threw $1.74 worth of coins on the table.

The 95% confidence interval estimate for the population proportion of car deals that used 0% financing is (0.1612, 0.2308). So, the correct option is (b).

To construct a confidence interval estimate for the population proportion of car deals that used 0% financing, we can use the formula

CI = p ± z√((p(1-p))/n)

where

p = sample proportion = 98/500 = 0.196

n = sample size = 500

z = z-score for the desired level of confidence, which is 95% in this case. From a standard normal distribution table, the z-score corresponding to 95% confidence level is approximately 1.96.

Substituting the values, we get

CI = 0.196 ± 1.96√((0.196(1-0.196))/500)

= (0.1612, 0.2308)

Therefore, the 95% confidence interval estimate is (0.1612, 0.2308).

Answer:133.4

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given 3 points, you want the fourth point that defines a rectangle. Then you want the length, width, and area of the rectangle. {(3, 2), (3, -3), (-5, -3)}

A rectangle is a quadrilateral (4-sided polygon) with opposite sides the same length and parallel, and all corners 90°.

We can name the given points A(3, 2), B(3, -3), and C(-5, -3).

When you plot the given points, you can imagine they form a right triangle with the right angle at B. The missing sides of the rectangle are ...

A line parallel to BC through A, and a line parallel to AB through C.

The equation of the first line is y = 2, and the equation of the second line is x = -5. These two lines meet at the point (x, y) = (-5, 2)

The missing point is (-5, 2).

We generally think of "length" as being the longer dimension of the figure. Here, the points B and C are farther apart than the points A and B. The distance between those points is the difference of their x-coordinates:

  length = 3 -(-5) = 8

The length of the rectangle is 8 units.

As with length, we can determine the distance between points A and B as the difference of their y-coordinates:

  width = 2 -(-3) = 5

The width of the rectangle is 5 units.

The area of a rectangle is the product of its length and width:

  A = LW

  A = (8)(5) = 40 . . . . square units

The area of the rectangle is 40 square units.

__

Additional comment

When the sides of the rectangle are on grid lines, as here, finding the missing point and the various lengths is pretty easy.

You will notice that there are two different x-coordinates and two different y-coordinates among the four points. The four points are those coordinates in every combination. One way to find the missing point is to find the missing combination. The side lengths are the difference between x-coordinates and the difference between y-coordinates. (This works for rectangles aligned to the grid.)

When the sides are skew with respect to the grid lines, a different strategy for locating the missing point and for finding side lengths is required. That strategy can make use of the fact that the diagonals cross at their midpoints, and the length is given by the distance formula.

In the case of Alicia, The single net increase is 5.821% of the original price.

Alicia is buying shoes at a department store that offers a 15% discount on all shoes. Additionally, she has a store card that gives her another 5% discount. However, at checkout, the cashier tells her that there will be two increases, one of 2% for commissions and another of 18% for general sales tax. To determine if there is a net discount or increase, we need to calculate the total discount and total increase separately and compare them.

First, let's calculate the total discount:

Next, let's calculate the total increase:

If the total discount is greater than the total increase, then there is a net discount. If the total increase is greater than the total discount, then there is a net increase.

Therefore, we need to compare:

Simplifying both expressions, we get:

Since 1.0506 x Original Price is greater than 0.20 x Original Price, we can conclude that there is a net increase.
