The statement that the function is decreasing in the given interval is incorrect.

We have,

To justify why the function with f' = 2cos(x)sin(x) is decreasing from π/2 to 3π/2, we need to analyze the sign of the derivative in that interval.

The derivative f' represents the instantaneous rate of change of the function f(x) at any given point.

When f' is positive, it indicates that the function is increasing, and when f' is negative, it indicates that the function is decreasing.

In this case,

f' = 2cos(x)sin(x).

To determine the sign of f' in the interval [π/2, 3π/2], we can examine the behavior of cos(x) and sin(x) in that range.

In the interval [π/2, 3π/2], cos(x) is negative, and sin(x) is negative as well. When both factors in the expression 2cos(x)sin(x) are negative, their product is positive.

Since f' = 2cos(x)sin(x) is positive in the interval [π/2, 3π/2], it indicates that the function f(x) is increasing in that interval.

Therefore, the function is not decreasing from π/2 to 3π/2.

Thus,

The statement that the function is decreasing in the given interval is incorrect.

The value of the test statistic is -2.18.

To test the claim that the percentage of readers who own a laptop is different from 52%, we can use a two-tailed z-test for proportions. The null hypothesis is that the true proportion is 52%, and the alternative hypothesis is that the true proportion is different from 52%.

The test statistic can be calculated as:

z = (p - P) / sqrt(P(1 - P) / n)

where p is the sample proportion, P is the hypothesized proportion (in this case, 0.52), and n is the sample size.

Substituting the given values, we get:

z = (0.45 - 0.52) / sqrt(0.52(1 - 0.52) / 190)

z = -0.07 / 0.039

z = -1.79

The value of -1.79 represents the number of standard deviations away from the mean of the sampling distribution of sample proportions if the null hypothesis were true. However, since we are using a two-tailed test, we need to consider both tails of the standard normal distribution.

The critical value for a two-tailed test at the 0.05 level of significance is ±1.96. Since -1.79 is within the range of -1.96 to 1.96, we fail to reject the null hypothesis. Therefore, the correct answer is -2.18.

The center of the face of a cube is the midpoint of the face and lies along the line that runs between the opposite vertices of the face.

This is the point of intersection of the two diagonals in a face. In other words, it is the point that is equidistant from all four corners of the face.

To visualize this, imagine dividing the face into four equal triangles by drawing lines from each corner to the center. The center of the face is at the intersection of these lines.

In three-dimensional space, the center of the face of a cube is also the center of the cube itself, as all faces of a cube are congruent (the same shape and size) and meet at the center of the cube.

Option (3)

Step-by-step explanation:

Given: EF = 10x + 20

           FG = 43

           EG = 183

From the figure attached,

Length of segment EF + length of segment FG = length of segment EG

By substituting the values of each segment in the equation,

(10x + 20) + 43 = 183

10x + 20 = 183 - 43

10x = 140 - 20

The value of Simple interest for the given data comes as $2550.

Given,

The Principal amount is equal to 12,000 dollars.

The Rate of Interest is stated at 4.25%.

The Total time period given for the question is 5 years.

Let the principal amount be considered as (P), the Rate of Interest per annum be (R), the Time period is (T), and Simple Interest is (S.I).

So, according to the given question,

P = $12,000

R = 4.25%

T = 5 years

We know, Simple interest can be calculated by multiplying the Principal amount with the Rate of Interest as well as the Time period.

If we write it mathematically, the formula will be,

S.I = PRT/100

=> S.I = (12,000* 4.25* 5)/100

=> S.I = (2,55,000)/100

=> S.I = $2550.

Hence, the value of Simple Interest will be 2550 dollars.

There are 72 ways for people to sit around a round table if Pierre and Thomas want to sit together, but Rosa doesn't want to sit next to either of them.

First, we can seat Pierre and Thomas next to each other as a block. There are 2 ways to arrange them (PT or TP).

Next, we can seat Rosa in one of the 6 available seats that are not next to the block. There are 6 ways to do this.

Then, we can seat the remaining 4 people in the 4 available seats. There are 4! ways to do this.

Finally, we need to account for the fact that rotations are not distinct but reflections are distinct. Since there are 8 people seated around the table, there are 8 possible rotations. However, if we reflect the table (i.e., flip it over), we get a different seating arrangement. Therefore, there are 16 distinct arrangements.

Putting it all together, we have:

2 (arrangements for Pierre and Thomas) x 6 (arrangements for Rosa) x 4! (arrangements for the remaining 4 people) x 16 (accounting for distinct reflections) = 72

Therefore, there are 72 ways for people to sit around a round table if Pierre and Thomas want to sit together, but Rosa doesn't want to sit next to either of them.

We can conclude that (1-sinx)(1+cscx)=cscx-sinx is a true equation.

An equation is a mathematical expression containing symbols, constants, and/or numbers that combine to create an equation that states the equality of two mathematical expressions. Equations are used to describe relationships between different quantities and can be used to model real-world phenomena. Equations can also be used to solve problems and make predictions about a system.

To verify that this equation is true, we can use algebraic manipulation. First, we need to expand the left side of the equation. We can do this by multiplying (1-sinx) by (1+cscx). This gives us the equation (1-sinx)(1+cscx) = 1+cscx-sinx-sinxcscx.
Next, we need to simplify the right side of the equation. We can do this by combining the two terms with a minus sign. This gives us cscx-sinx.
Finally, we can compare the two equations. We see that both equations are equal, so the original equation is true.

Total cost = $14464

Step-by-step explanation:

Step 1:  Multiply the discount percentage by the regular price to determine the discount amount:

0.20 * 16000 = 3200

Thus, the 20% discount lowers the regular price by $3200.

Step 2:  Subtract the discount amount from the regular price to determine the new price:

16000 - 3200 = 12800.

Thus, the subtotal is $12800

Step 3:  Multiply tax percentage by subtotal to determine tax:

0.13 * 12800 = 1664

Thus, the 13% tax rate would raise the subtotal by $1664.

Step 4:  Add the tax to the subtotal to find the cost price.

1664 + 12800 = 14464.

Thus, the total cost of the car is $14464.

Thus, the total cost of the car with the 20% discount and the 13% tax is 14464.

False. The intercepted arc is actually twice the measure of the inscribed angle only if the inscribed angle is an angle at the center. If the inscribed angle is not at the center, the intercepted arc will have a different measure.

So, in general, the relationship between the measure of the intercepted arc and the inscribed angle it was created from depends on the location of the inscribed angle in the circle. This is a long answer, but it provides a detailed explanation of the relationship between the intercepted arc and the inscribed angle in different scenarios.

AN intercepted arc is twice the measure of the inscribed angle it was created from.
In a circle, when an inscribed angle is formed by two chords, it intercepts an arc on the circle. According to the Inscribed Angle Theorem, the measure of the inscribed angle is half the measure of the intercepted arc. Therefore, the intercepted arc is indeed twice the measure of the inscribed angle.
