Remark

You have an isosceles triangle. That means that the angles opposite the marked sides are equal. So mark the angle on the lower left of the triangle as 50 degrees.

The solution to problem depends on the fact that the sum of the two inside angles of the triangle (each of which is marked as 50 degrees) not supplementary to the exterior angle, are still equal to the exterior angle.

Givens

<1 = 50 degrees

<2 = 50 degrees

Exterior angle = 15x + 25   Substitute the givens into the equation

Equation

<1 + <2 = 15x + 25

Solution

50 + 50  = 15x + 25                       Combine the left side

100 = 15x + 25                               Subtract 25 from both sides

100 - 25 = 15x + 25 - 25                Combine

75 = 15x                                          Divide both sides by 15

75/15 = 15x/15                      

5 = x

Answer

<1 = 50 degrees

<2 = 50 degrees

15x + 25 = 75 + 25 = 100

The probability that a voter is either female or Democrat is 0.64 or 64%.

To calculate the probability, we need to determine the number of individuals who are either female or Democrat and divide it by the total number of voters.

From the table, we can see that there are 405 females and 253 Democrats. However, we need to be careful not to double-count the individuals who fall into both categories.

To find the number of individuals who are either female or Democrat, we add the number of females (405) and the number of Democrats (253), and then subtract the number of individuals who are both female and Democrat (150).

So, the number of individuals who are either female or Democrat is 405 + 253 - 150 = 508.

Now, we divide this number by the total number of voters, which is 802, to get the probability: 508 / 802 ≈ 0.64 or 64%.

Therefore, the probability that a voter is either female or Democrat is approximately 0.64 or 64%.

Free samples or product trials as a type of sales promotion can be both beneficial and detrimental. They encourage consumers to try a product at reduced risk, but they can also reduce the perception of value for the product or service.

Offering free samples or product trials is a common sales promotion strategy to attract customers and encourage them to try a product or service. This approach has several benefits. Firstly, it lowers the perceived risk for consumers as they can experience the product without making a financial commitment upfront. This can be especially effective for new or unfamiliar products, as it allows potential customers to test the product's quality and functionality.

However, there can be drawbacks to this sales promotion technique. Providing free samples or trials can create the perception that the product or service has less value or is of lower quality. Consumers may develop a mindset of expecting free or discounted offerings, and it can undermine the willingness to pay the full price in the future. Additionally, if the free samples or trials are not managed effectively, it may attract individuals who are not genuinely interested in the product, leading to wastage of resources and potentially diluting the brand image.

The series is convergent and its sum is -0.6.

The given series can be written as:

Σ n=1 |(0.5)^n-1-(0.2)^n|

Using the formula for the sum of an infinite geometric series, we can write each term of the series as:

|(0.5)^n-1-(0.2)^n| = |(0.5)^(n-1) - (0.2)^n| = (0.5)^(n-1) - (0.2)^n

We can now write the series in a simpler form as:

Σ n=1 ((0.5)^(n-1) - (0.2)^n)

Next, we need to determine whether this series is convergent or divergent. To do this, we can use the ratio test. The ratio of consecutive terms is:

((0.5)^n-1 - (0.2)^n)/((0.5)^(n-1) - (0.2)^(n-1)) = (0.5 - (0.2)^n/(0.5))

As n approaches infinity, the second term in the numerator approaches zero and the ratio approaches 1/2. Since the ratio is less than 1, the series is convergent.

To find the sum of the series, we can use the formula for the sum of a geometric series:

a/(1-r)

where a is the first term and r is the common ratio. Here, a = 0.3 and r 0.5.

The sum of the series is thus:

0.3/(1-0.5) = 0.6

However, since the original series was expressed in absolute value, we need to take the negative of this sum to get the final answer:

-0.6

Therefore, the series is convergent and its sum is -0.6.

Number of  photos will be required to cover the area for the given data is 62,537

To determine the number of photos required to cover the given area, we need to calculate the area that each photo can cover.

Calculation of Ground Resolution (GSD)

The Ground Sampling Distance (GSD) is a measure of the resolution of the camera, which is the distance on the ground represented by each pixel in the image.

We can calculate the GSD using the formula:

GSD = (focal length / flying height) x (image dimension / ground dimension)

Here, the focal length is given as 6 inches.

The flying height can be calculated using the scale of the photograph, which is 1:6000. This means that one unit on the photograph represents 6000 units on the ground.

Therefore, 1 inch on the photograph represents 6000 inches on the ground.

Since the area to be covered is 6 x 6 mi2, we need to convert the area to inches:

1 mile = 5280 feet = 63360 inches

Area in inches = (6 x 63360) x (6 x 63360) = 144,998,400 square inches

To cover this area with a scale of 1:6000, we need a flying height of:

1 inch on the photograph = 6000 inches on the ground

Flying height = (1 / 6000) x focal length = 0.001 x 6 = 0.006 miles

To convert this to feet, we multiply by 5280:

Flying height = 0.006 x 5280 = 31.68 feet

Now we can calculate the GSD:

GSD = (6 / 31.68) x (9 / 63360) = 0.00000318 square inches

Calculation of Photo Coverage Area

To calculate the area that each photo can cover, we need to determine the area of the photograph based on the GSD.

The area of the photograph can be calculated as:

Area of photograph = GSD x image dimension x image dimension

Area of photograph = 0.00000318 x 9 x 9 = 0.00020412 square miles

Calculation of Number of Photos Required

Now we can calculate the number of photos required to cover the area.

End overlap is given as 60%, which means that each photo overlaps with the adjacent photo by 60% in the direction of flight.

Side overlap is given as 30%, which means that each photo overlaps with the adjacent photo by 30% perpendicular to the direction of flight.

Therefore, the area covered by each photo with overlap is:

Area covered by each photo = Area of photograph x (1 - side overlap) x (1 - end overlap)

Area covered by each photo = 0.00020412 x 0.7 x 0.4 = 0.00005722 square miles

To cover the total area of 6 x 6 mi2, we need to divide the total area by the area covered by each photo:

Number of photos required = (6 x 6) / 0.00005722 = 62,537

The value of the expression tan(-5π/6) can be determined using trigonometric properties and  identities.

First, let's consider the unit circle. The angle -5π/6 is measured in the clockwise direction from the positive x-axis. In this position, the reference angle is π/6, which is the positive angle formed with the x-axis.

The tangent function (tan) is defined as the ratio of the sine (sin) of an angle to the cosine (cos) of the angle. Using the reference angle π/6, we can determine the value of tan(π/6) as the ratio of sin(π/6) to cos(π/6). sin(π/6) equals 1/2, and cos(π/6) equals √3/2. Therefore, tan(π/6) is (1/2) divided by (√3/2), which simplifies to 1/√3 or √3/3. Since tan is an odd function, tan(-5π/6) is equal to the negative of tan(5π/6). Therefore, tan(-5π/6) has the same value as -√3/3.

In conclusion, the value of tan(-5π/6) is -√3/3, which means that the tangent of the angle -5π/6 is negative and equal to the ratio of -√3 to 3.
