The height of the cliff is approximately 269 feet.

We will be using the tangent function to find the height of the cliff.
Draw a right triangle with the rowboat at one corner, the cliff's base as the adjacent side, and the cliff's height as the opposite side.

The angle of elevation (73.8 degrees) is between the rowboat and the cliff's base.
We are given the adjacent side (75 feet) and we need to find the opposite side (height of the cliff).

To do this, we will use the tangent function:
tan(angle) = opposite side / adjacent side
Plug in the given values:
tan(73.8) = height / 75
Solve for the height:
height = tan(73.8) * 75
Calculate the value:
height ≈ 269.4 feet
Round the height to the nearest foot:
height ≈ 269 feet.

The length of the side LK is 48

From the information given, we have that;

The triangles JKL and the triangle TUV are equal

Then, we have that;

The adjacent side of JKL is 40

The adjacent side of TUV is 6x + 12

Now, equate the lengths of the sides, we have;

6x + 12 = 48

Now, collect the like terms, we have;

6x = 48-12

subtract the values, we have;

6x = 36

Divide both sides by the coefficient, we get;

x = 6

Then, LK = 6(6) + 12 = 36 + 12 = 48

Answer:

x = -1

Step-by-step explanation:

The axis of symmetry of the graph \(y=(x-3)^2\) is  x=3 but,

If shift the graph 4 units to the left it would mean the new value of x would be -1 as shown here:

\(x=3-4\\x=-1\)

-4 because it shifted 4 units to the left so the axis of symmetry of the transformed graph would be x = -1 and since it shifted 2 units down the y-coordinate of the turning point would be -2 so the turning point of the original graph is (3 , 0) and the turning point of the transformed graph is

The x-coordinate of P is -√(-2303), which is found to be approximately -47.9894.

The point P is on the unit circle. If the y-coordinate of P is 48, and P is in Quadrant II, then, to find out the x-coordinate of P, we can use the Pythagorean Theorem, which states that 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 O be the origin (0, 0), and let A be the point on the unit circle that intersects the line y = 48 and is in Quadrant II.

We know that OA = 1, and we need to find the x-coordinate of A.

Since A is in Quadrant II, its x-coordinate is negative.

The y-coordinate of A is the length of the side opposite to the angle between the hypotenuse and the x-axis, and the hypotenuse is 1 unit long.

Therefore, the length of the adjacent side (the x-coordinate of A) is given by:

x = -√(1² - 48²)

= -√(1 - 2304)

= -√(-2303) ≈ -47.9894

Therefore, the point A is approximately (-47.9894, 48) on the unit circle. In summary, the x-coordinate of P is -√(-2303), which is approximately -47.9894.

The point A is approximately (-47.9894, 48) on the unit circle.

The explicit formula for the nth term of the sequence 14,16,18,... is aₙ = 2n + 12.

What is an explicit formula?

The explicit equations for L-functions are the relationships that Riemann introduced for the Riemann zeta function between sums over an L-complex function's number zeroes and sums over prime powers.

Here, we have

Given:  the sequence 14,16,18,….

First term a₁ = 14

Common difference d = 16 - 14 = 2

Now, plug the values into the above formula and simplify.

aₙ = a₁ + d( n - 1 )

aₙ = 14 + 2( n - 1 )

aₙ = 14 + 2n - 2

aₙ = 14 - 2 + 2n

aₙ = 2n + 12

Hence,  the explicit formula is aₙ = 2n + 12.

The amount you could save per month would be 25% of your discretionary money.

Discretionary income is the money you have left over after paying taxes and necessary cost-of-living expenses.

The formula for discretionary money is: Discretionary money = Realized income - Fixed expenses. Inputting data, we have: Discretionary money = $3,543.22 - Fixed expenses

Amount to be saved = 25% of discretionary money

Amount to be saved = 0.25 * (Realized income - Fixed expenses)

Therefore, the amount savable is calculated as 0.25 times the difference between your realized income and fixed expenses.

This means that we can be 95% confident that the true population means difference lies between 1.7075 and 10.2925.

Confidence interval = Mean difference ± (t-value × standard error)

Substituting the given values into the formula, we get:

Confidence interval = 6 ± (2.045 × 2.1)

Confidence interval = 6 ± 4.2925

A confidence interval is a statistical concept used to estimate the range of values in which a population parameter is likely to fall. It is calculated using sample data and is used to provide an estimate of the true population parameter.

The confidence interval is a range of values that is constructed around a point estimate, such as the sample mean or proportion. This range is based on the level of confidence chosen by the researcher, typically 90%, 95%, or 99%. For example, a 95% confidence interval means that if we were to repeat the sampling process many times, we would expect the true population parameter to fall within the range of values calculated for 95% of those samples.

There exists a value c in the interval (2, 4) such that f(c) = 15.

Given that f is a function that is continuous on the closed interval [2, 4] and f(2) = 10 and f(4) = 20, we can use the Intermediate Value Theorem to show that there exists a value c in the interval (2, 4) such that f(c) = 15.

The Intermediate Value Theorem states that if a function f is continuous on a closed interval [a, b], and if M is any value between f(a) and f(b) (inclusive), then there exists at least one value c in the interval (a, b) such that f(c) = M.

In this case, f(2) = 10 and f(4) = 20, and we are interested in finding a value c such that f(c) = 15, which is between f(2) and f(4). Since f is continuous on the interval [2, 4], the Intermediate Value Theorem guarantees that such a value c exists.

Therefore, there exists a value c in the interval (2, 4) such that f(c) = 15.
