x = ±π/6 + πn, ±11π/12 + πn, where n is an integers are solutions of the equation  cos²x = sin²x + 1/2

To solve the equation cos²x = sin²x + 1/2, we can use the trigonometric identity sin²x + cos²x = 1.

Rearranging the equation, we have:

cos²x - sin²x = 1/2

Using the identity cos²x - sin²x = cos(2x), we can rewrite the equation as:

cos(2x) = 1/2

The solutions to this equation can be found by taking the inverse cosine (or arccosine) of both sides:

2x = ±π/3 + 2πn, ±11π/6 + 2πn, where n is an integer

Dividing both sides by 2, we get:

x = ±π/6 + πn, ±11π/12 + πn, where n is an integers

Answer:

To calculate the cost of the mortgage, we need to find the total amount that Sonya will pay back over the 25-year period.

One way to do this is to use the formula for the future value of an annuity, which is:

FV = Pmt x ((1 + r)^n - 1) / r

where FV is the future value, Pmt is the periodic payment, r is the interest rate per period, and n is the number of periods. In this case, we want to find the total future value of the mortgage payments over 25 years, so we can set Pmt equal to the monthly mortgage payment, r equal to the monthly interest rate, and n equal to the total number of months in 25 years.

First, let's convert the annual interest rate to a monthly interest rate by dividing by 12:

r = 7% / 12 = 0.00583

Next, we can use an online mortgage calculator or a spreadsheet to find the monthly mortgage payment based on the loan amount, interest rate, and term. For a $65,000 mortgage at 7% for 25 years, the monthly payment is approximately $471.78.

Finally, we can plug in the values into the formula for the future value of an annuity:

FV = $471.78 x ((1 + 0.00583)^300 - 1) / 0.00583

FV ≈ $141,535.15

Therefore, the total cost of the mortgage over 25 years is approximately $141,535.15. This includes the original loan amount of $65,000 plus the interest that accumulates over the 25-year period.

The solution to the integration of the function given, ∫√(5x - 1) dx, is:

[tex]\frac{2}{15}(5x-1)^{3/2} + C[/tex]

To solve the integral of:

√(5x - 1) dx

we can use a u-substitution.

Let u = 5x - 1, then:

du = 5 dx

dx = du/5

Now we can rewrite the integral in terms of u:

∫√(5x - 1) dx = ∫√u * (du/5)

Simplifying the integral:

(1/5) ∫√u du

Integrating √u:

(1/5) * (2/3) * u^(3/2) + C

Where C is the constant of integration

Substituting back u = 5x - 1:

(2/15) * (5x - 1)^(3/2) + C

Answer:

3/5=9/15

Step-by-step explanation:

In order to turn 2/3 and 3/5 using 15 as the common denominator, we must first find out how much we need to multiply the denominator by to get 15 and use that amount to also multiply the numerator. In 2/3 the 3 needs to be multiplied by 5, therefore we also multiply the 2 by 5 giving us the result of 10/15 for the 2/3 problem. For the 3/5 we use the same tactic. The 5 in 3/5 needs to be multiplied by 3 to get to 15, therefore we multiply the 3 by 3 as well to get 9/15.

The marksman hit 54% of the targets last year when expressed as a percentage, based on hitting 27 out of 50 targets from a distance of 100 yards.

From the given information, we know that a marksman hit 27 out of 50 targets last year from a distance of 100 yards.

To analyze this data, we can calculate the hit rate or success rate of the marksman. The hit rate is calculated by dividing the number of hits by the total number of attempts or trials.

Hit rate = Number of hits / Total number of attempts

In this case, the number of hits is 27, and the total number of attempts is 50.

Hit rate = 27 / 50

Simplifying the fraction, we get:

Hit rate = 0.54 or 54%

Therefore, the marksman had a hit rate of 54% last year.

This means that out of the 50 targets attempted from a distance of 100 yards, the marksman successfully hit 27 of them.

The hit rate serves as a measure of accuracy and effectiveness in target shooting. A higher hit rate indicates a higher level of skill and precision.

It's important to note that other factors such as weather conditions, visibility, and the difficulty level of the targets can influence the hit rate. Additionally, the marksman's skills may improve or vary over time, so this hit rate represents their performance specifically for the past year.

By analyzing the hit rate, we can gain insights into the marksman's accuracy and assess their proficiency in target shooting from a distance of 100 yards.

The graph of the equation y = -1 is a horizontal line passing through (0, -1), and the graph of the equation 3x - y = 4 is a line passing through the points (-2, -10), (0, -4), and (2, 2).

To graph the given equations, we'll plot the points that satisfy each equation and then connect them to form a line.

Equation 1: y = -1

This equation represents a horizontal line passing through the y-coordinate -1. Regardless of the x-coordinate, the y-value remains constant at -1. Therefore, we plot a point at (0, -1) and draw a horizontal line through that point.

Equation 2: 3x - y = 4

To graph this equation, we can rewrite it in terms of y:

y = 3x - 4

Now we can choose a few x-values, substitute them into the equation, and solve for y to obtain the corresponding y-values. Let's select three x-values: -2, 0, and 2.

For x = -2:

y = 3(-2) - 4

y = -6 - 4

y = -10

For x = 0:

y = 3(0) - 4

y = -4

For x = 2:

y = 3(2) - 4

y = 6 - 4

y = 2

Now we have three points: (-2, -10), (0, -4), and (2, 2). Plotting these points on the graph, we can draw a line connecting them.

In summary, the graph of the equation y = -1 is a horizontal line passing through (0, -1), and the graph of the equation 3x - y = 4 is a line passing through the points (-2, -10), (0, -4), and (2, 2).
