The exact value  of \(sin 2x\) is \(4√5/9.\)

Given that \(sec x = 3/2 and csc y = 3\)where x and y are in the 2x = 2 sin x quadrant, we need to find the exact value of sin 2x.

In the first quadrant, we have the following values of the trigonometric ratios:\(cos x = 2/3 and sin y = 3/5\)

Also, we know that sin \(2x = 2 sin x cos x.\)

Now, we need to find sin x.

Having sec x = 3/2, we can use the Pythagorean identity

\(^2x + 1 = sec^2xtan^2x + 1 = (3/2)^2tan^2x + 1 = 9/4tan^2x = 9/4 - 1 = 5/4tan x = ± √(5/4) = ± √5/2\)

As x is in the first quadrant, it lies between 0° and 90°.

Therefore, x cannot be negative.

Hence ,\(tan x = √5/2sin x = tan x cos x = √5/2 * 2/3 = √5/3\)

Now, we can find sin 2x by using the value of sin x and cos x derived above sin \(2x = 2 sin x cos xsin 2x = 2 (√5/3) (2/3)sin 2x = 4√5/9\)

Therefore, the exact value  of sin 2x is 4√5/9.

The statement of pre-image is dilated is the resulting image congruent to the origina is false.

A dilation is a change that creates a picture that is a similar shape as the first, however is an alternate size. • An expansion that makes a bigger picture is called a development. • An expansion that makes a more modest picture is known as a decrease.

As we all know that dilation is used to resize the object. It make the objects larger or smaller.

It produces an image that is the same shape as the original, but is a different size.

This means, the original figure and the transformed figure would not be congruent.

Therefore, the statement 'When an object is dilated, the resulting image is congruent to the pre-image.' is False

To determine if the boards create a right triangle, Joey can use the Pythagorean theorem. According to the theorem, in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Let's assume Joey measures the lengths of the two sides as a and b, and the hypotenuse as c. The Pythagorean theorem can be written as:

\(c^2 = a^2 + b^2\)

If the measured values satisfy this equation, then the boards form a right triangle. Joey can substitute the measured lengths into the equation and solve for \(c^2\). If \(c^2\) is equal to the sum of the squares of \(a^2\) and \(b^2\), then the boards form a right triangle.

Step-by-step explanation:

It says that in 2008, St. Lucie Village had a population of 500 people.  

The solution for x in the equation given as 3/2 (4x – 1) – 3x = 54 –(x + 2) is 13.375

From the question, the algebraic expression is given as

3/2 (4x – 1) – 3x = 54 –(x + 2)

There is no constant to multiply or divide in the expression

3/2 (4x – 1) – 3x = 54 –(x + 2)

Open the brackets

So, we have

6x – 3/2 - 3x = 54  - x - 2

Collect the like term in the above equation

This gives

6x - 3x + x = 54 - 2 + 3/2

Evaluate the like term in the above equation

So, we have the following representation

4x = 53.5

Divide through by 4

x = 13.375

The above equation cannot be solved further

Hence, the solution is x = 13.375

Step-by-step explanation:

1 soccer ball =$12

2 makes $24.

24+16=40

so both coaches spend 8 bucks for 4 cones

Each cone costs $2, and the cost is calculated as follows: 8x = 40 - 2 *p, where p is equal to the cost of a football.

A linear equation is an algebraic equation of the form ax + by +c, is and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given that, Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount. Together the coaches spend $40.

Let x be the number price of the cone.

Thus each coach spends  = 4x  +12

Thus, in total, they spend = 40

4x  +12 +  4x  +12 = 40

8x = 40 -24

8x = 16

x = 2

Therefore, Each cone costs $2 and the equation for calculating the price of the cone is: 8x = 40 - 2 * the price of a football.

To determine whether to reject or fail to reject the null hypothesis, we typically rely on statistical hypothesis testing. After conducting a hypothesis test, we consider the test statistic and the corresponding p-value.

When the p-value is less than or equal to the predetermined significance level (usually denoted as α), we reject the null hypothesis. This indicates that the observed data provides sufficient evidence to support the alternative hypothesis. Conversely, when the p-value is greater than the significance level, we fail to reject the null hypothesis. In this case, we do not have enough evidence to support the alternative hypothesis.

The significance level α is predetermined and represents the probability of making a Type I error, which is the rejection of the null hypothesis when it is actually true. Commonly used significance levels include 0.05 (5%) and 0.01 (1%). The choice of the significance level depends on the specific research context and the consequences of making a Type I error.

It is important to note that failing to reject the null hypothesis does not necessarily mean that the null hypothesis is true. It simply means that the observed data does not provide enough evidence to support the alternative hypothesis. There could still be other factors or limitations in the study that contribute to the lack of significant results.

A vertical asymptote example is a graph that shows an equation such as 1/x approaching infinity as x approaches 0. In this example, x = 0 is the vertical asymptote.

A vertical asymptote is a line on a graph that represents the point at which a function approaches infinity or negative infinity. In other words, it is the point at which the graph of the function becomes infinitely steep. An example of a vertical asymptote is the equation 1/x. As x approaches 0, the value of 1/x approaches infinity. This is represented on the graph of the equation as a vertical line at x = 0. This line is the vertical asymptote. A vertical asymptote indicates that the domain of the function does not include the point at which the asymptote occurs. This is because a function cannot approach infinity. Thus, the equation 1/x is not defined at x = 0.

The monthly payment on a $90,000, 15-year mortgage at 5.0% interest is approximately $632.07.

To calculate the monthly payment on a $90,000, 15-year mortgage with a 5.0% interest rate, we can use the formula for calculating the monthly payment on a fixed-rate mortgage. The formula is:

M = P [i(1 + i)^n] / [(1 + i)^n - 1]

Where:

M = Monthly payment

P = Loan amount

i = Monthly interest rate

n = Number of monthly payments

Let's plug in the given values into the formula and calculate the monthly payment step by step:

Loan amount (P) = $90,000

Interest rate (5.0%) = 0.05

Number of monthly payments (15 years) = 15 * 12 = 180

First, we need to calculate the monthly interest rate (i):

i = 0.05 / 12 = 0.0041667

Next, we calculate the denominator of the formula:

(1 + i)^n - 1 = (1 + 0.0041667)^180 - 1 = 2.3231131

Finally, we can calculate the monthly payment (M):

M = $90,000 * 0.0041667 * 2.3231131 / 2.3231131 = $632.07 (rounded to the nearest cent)

Therefore, the monthly payment on a $90,000, 15-year mortgage at 5.0% interest is approximately $632.07.

The standard deviation of the outcome for the given bet is approximately $51.

To obtain this result, we can use the following formula for the standard deviation of a random variable with two possible outcomes (winning or losing in this case):SD = √(p(1-p)w² + p(1-p)l²),where SD is the standard deviation, p is the probability of winning (0.4 in this case), w is the amount won ($50 in this case), and l is the amount lost ($50 in this case).

Plugging in the values, we get:SD = √(0.4(1-0.4)(50²) + 0.6(1-0.6)(-50²))≈ $51

Therefore, the standard deviation of the outcome of the given bet is approximately $51.Explanation:In statistics, the standard deviation is a measure of how spread out the values in a data set are.

A higher standard deviation indicates that the values are more spread out, while a lower standard deviation indicates that the values are more clustered together.

In the context of this problem, we are asked to find the standard deviation of the outcome of a bet. The outcome can either be a win of $50 with a probability of 40% or a loss of $50 with a probability of 60%.

To find the standard deviation of this random variable, we can use the formula:SD = √(p(1-p)w² + p(1-p)l²),where SD is the standard deviation, p is the probability of winning, w is the amount won, and l is the amount lost.

Plugging in the values, we get:SD = √(0.4(1-0.4)(50²) + 0.6(1-0.6)(-50²))≈ $51Therefore, the standard deviation of the outcome of the given bet is approximately $51.
