The boat is approximately 515 feet away from the lighthouse.

To find the distance from the boat to the lighthouse, we can use trigonometry. The angle of depression from the person to the boat is 28°, and the height of the lighthouse is 200 feet. Let's call the distance from the boat to the lighthouse x. Using the tangent function, we have

Solving for x, we have x = 200 / tan 28°. Approximating this value using a calculator, we have x ≈ 514.7 feet. Rounding to the nearest foot, the boat is approximately 515 feet away from the lighthouse.

The length of the four-acre lot with front footage of 250 feet is approximately 693.76 feet.

In mathematics, "acre" is a unit of area that is commonly used to measure the size of a piece of land. One acre is equal to 43,560 square feet. To find the length of the lot, we need to know the area of the lot and the front footage.

Here we need to determine the length of a four-acre lot with front footage of 250 feet, we need to use the concept of area and the formula for calculating the area of a rectangle.

In this case, the area of the lot is four acres, or

=> 4 x 43,560 = 173,440 square feet.

In order to find the length of the lot, we can divide the area by the front footage, which is 250 feet.

By using the formula for the area of a rectangle, we can write this as:

=> Area = Length x Front Footage

Therefore, Length  is calculated as

=> Area / Front Footage = 173,440 / 250 = 693.76 feet.

where , d(AB) is the distance between the two points A and B.

hope helpful! :)

Answer:

the Distance Between the two points a and b

Step-by-step explanation:

Distance between two points is the length of the line segment that connects the two points in a plane. The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²). This formula is used to find the distance between any two points on a coordinate plane or x-y plane.

The local maximum is x = 13.5 with a value of g(13.5) = (13.5)^2 - 27 * 13.5 = g(13.5) = 125.375.

(a) To determine whether a function is even, odd, or neither, we need to check if g(x) = g(-x) for all x (even), g(x) = -g(-x) for all x (odd), or neither.

g(x) = x^2 - 27x is neither even nor odd because it does not satisfy either of the two conditions for even or odd functions.

(b) To determine the local maximum, we need to find the critical points (points where the derivative is equal to zero or undefined) and then determine if they are local maxima, local minima, or neither.

g'(x) = 2x - 27, which has critical points at x = 13.5 and x = 0. Since g'(x) > 0 for x < 0 and g'(x) < 0 for x > 0, x = 0 is a local minimum. Since g'(x) < 0 for x < 13.5 and g'(x) > 0 for x > 13.5, x = 13.5 is a local maximum.

Therefore, the local maximum is x = 13.5 with a value of g(13.5) = (13.5)^2 - 27 * 13.5 = g(13.5) = 125.375.

The area of the small indoor greenhouse (herbarium) is equal to 4,250 cm².

The length of tape needed for all the 12 edges is equal to 320 cm.

Mathematically, the total surface area (TSA) of this glass panes (including base) can be calculated by using this mathematical expression:

Total surface area (TSA) = 2[lb + lh + bh]

Where:

Total surface area (TSA) = 2[(30 × 25) + (30 × 25) + (25 × 25)]

Total surface area (TSA) = 2[750 + 750 + 625]

Total surface area (TSA) = 2[2,125]

Total surface area (TSA) = 4,250 cm².

Next, we would determine the length of tape needed for all the 12 edges by using this mathematical expression:

Total length = 4(l + b + h)

Total length = 4(30 + 25 + 25)

Total length = 4(80)

the derivative of

25cosh(x/25)−20 with respect to x will be

The largest value of x that satisfies the inequality is approximately -1.8639.

To find the largest possible value of x that satisfies the inequality 1/(x + 2)⁶ > 1,000,000, we can start by rearranging the inequality:

1/(x + 2)⁶ > 1,000,000

Taking the reciprocal of both sides:

(x + 2)⁶ < 1/1,000,000

Now, let's take the sixth root of both sides:

x + 2 < (1/1,000,000)[tex]}^{1/6[/tex]

Calculating the right side:

x + 2 < 0.1361

Subtracting 2 from both sides:

x < 0.1361 - 2

x < -1.8639

Therefore, the largest value of x that satisfies the inequality is approximately -1.8639.

The value of x for each given right angled triangle are:

Please remember that these answers are calculated using calculator.

Remember that a triangle has the sum of angles 180°; then since we have a right angled triangle, then the sum of the non-right angles in the triangle should be equal to 90°.

We use Θ as the note for the unknown non-right angle.

1. 36° + Θ = 90°

Θ = 54°

Under the Sinus Law:

x / sin 54 = 7 / sin 90

x / 0.8 = 7 / 1

x = 5.6

2. 41° + Θ = 90°

Θ = 49°

Under the Sinus Law:

x / sin 49 = 6 / sin 90

x / 0.75 = 6 / 1

x = 4.52

3. 30° + Θ = 90°

Θ = 60°

Under the Sinus Law:

x / sin 90 = 6 / sin 60

x / 1 = 6 / (√3/2)

x = 4√3

4. 37° + Θ = 90°

Θ = 53°

Under the Sinus Law:

5 / sin 53 = x / sin 90

x = 5 / 0.79

x = 6.26

5. 33° + Θ = 90°

Θ = 57°

Under the Sinus Law:

7 / sin 90 = x / sin 57

7 / 1 = x / 0.84

The range of the function is {0, 4, 10}. Option A. {0, 4, 10}

The concept used in finding the range of a function is called functional mapping, which maps the elements in the domain of the function to the corresponding elements in the range.

In this problem, we took a set of values in the domain of the function (which was {-2, 0, 3}) and evaluated the function for each of those values to find the corresponding outputs in the range of the function, which was {0, 4, 10}.

To find the range of the function f(x) = 2x + 4 for the domain {-2, 0, 3}, we need to calculate the output of the function for each of the values in the domain:

For x = -2: f(-2) = 2 * -2 + 4 = -4 + 4 = 0

For x = 0: f(0) = 2 * 0 + 4 = 4

For x = 3: f(3) = 2 * 3 + 4 = 10

Therefore, the range of the function is {0, 4, 10}. Option A. {0, 4, 10}

The planes is 2x - y + 3z = 6.

The lines are x = 1 - t, y = 3t, z = 1 + t.

We now the value of x, y, z. So we put the value of x, y, z in the plane.

2x - y + 3z = 6

2(1 - t) - 3t + 3(1 + t) = 6

Simplifying

2 - 2t - 3t + 3 + 3t = 6

Divide by -2 on both side, we get
