From law of cosine formula, the width of lake for which Julia wants to determine the distance at certain points across a lake is equals to the 4023.4 meters.

Law of cosine in triangle is used to determine the length of third side of triangle when two other sides and angle between them is known. Cosine formula is c² = a² + b² - 2ab cosC , where

Julia wants to determine the distance at certain points across a lake. See the above figure and reconigse the measurements. Here, the width of lake is represented by AB. There is formed a triangle ABC, with following details,

Length of side AC = 2.82 mi

Length of side BC = 3.86 mi

Measure of angle C = 40.3°

We have to determine value of AB. Using the law cosine formula, AB² = BC² + AC² - 2AC× BC cosC

=> AB² = 2.82² + 3.86² - 2×2.82×3.86 ×cos( 40.3°)

=> AB² = 7.9524 + 14.8696 - 21.7764 ×cos( 40.3°)

=> AB² = 22.852 - 16.603

=> AB ² = 6.2485

=> AB = 2.4996

Hence, required width is 2.5 miles. But we needs answer in meter then convert miles into meters, 1 mile = 1609.344 m

so, 2.5 miles = 2.5 × 1609.344 meters = 4023.36 m ~ 4023.4 meters.

On average, approximately 3.152 customers will be waiting in the queue at the stadium.

To calculate the average number of customers waiting in the queue, we can use the queuing theory formulas. The arrival rate of customers is given as 180 per minute, which means the arrival rate is λ = 180/60 = 3 customers per second. The service time is given as an average of 21 seconds per customer, so the service rate is μ = 1/21 customers per second.

To calculate the utilization factor (ρ), we divide the arrival rate by the service rate: ρ = λ/μ. In this case, ρ = 3/1/21 = 9.857.

Next, we calculate the coefficient of variation for arrival time (C_a) and service time (C_s) using the given values. C_a = 13% = 0.13 and C_s = 13% = 0.13.

Using the queuing theory formula for the average number of customers waiting in the queue (L_q), we have L_q = ρ^2 / (1 - ρ) * \((C_{a}^2 + C_{s}^2)\) / 2.

Plugging in the values, L_q = \((9.857^2) / (1 - 9.857) * (0.13^2 + 0.13^2) / 2 = 3.152\).

Therefore, on average, approximately 3.152 customers will be waiting in the queue at the stadium.

Answer:

x = (13/9), -(3/9)

Step-by-step explanation:

|3x + 5| = 12x + 8

Since the equation is in absolutes we have

3x - 12x + 5 = 8

.: 5 - 9x = 8

-8 = 5 - 9x = 8

Remove 5 from both sides

-8 - 5 = -9x = 8 - 5

-13 = -9x = 3

x = (13/9), -(3/9)

The values of x for | 3x + 5 | = 12x + 8 is x = - 1/3 Or x = - 13/15.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

Given, | 3x + 5 | = 12x + 8.

So, (3x + 5) = 12x + 8 Or - (3x + 5) = 12x + 8.

3x + 5 = 12x + 8 Or -3x - 5 = 12x + 8.

- 9x = 3 Or - 15x = 13.

x = - 1/3 Or x = - 13/15.

The correct option is A, The error of rejecting a true null hypothesis is known as a Type I error in hypothesis testing.

A hypothesis is an educated guess or a tentative explanation for a phenomenon that can be tested through empirical research. It is a statement that provides a proposed explanation for a phenomenon based on limited evidence or observations. The goal of a hypothesis is to provide a framework for empirical testing, and to determine whether the data collected supports or disproves the hypothesis.

In science, a hypothesis is a crucial part of the scientific method. It helps scientists to define and clarify their research questions, to design experiments or studies, and to make predictions about the outcomes. A hypothesis should be testable, falsifiable, and based on previous research or observations.

Step-by-step explanation:

If f(x)=2x²-5x-3 g(x)=2x²+5x+2 then (f/g)(x) = (x - 3) / (x + 2).

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range.

To find (f/g)(x), we need to divide f(x) by g(x) as follows:

f(x) = 2x² - 5x - 3

g(x) = 2x² + 5x + 2

f(x) / g(x) = (2x² - 5x - 3) / (2x² + 5x + 2)

To simplify this expression, we can factor the numerator and denominator:

f(x) / g(x) = [(2x + 1)(x - 3)] / [(2x + 1)(x + 2)]

Now, we can cancel out the common factor of (2x + 1) from both the numerator and denominator:

f(x) / g(x) = (x - 3) / (x + 2)

Therefore, (f/g)(x) = (x - 3) / (x + 2).

Answer:

you'll see...

Step-by-step explanation:

Given that the transformed graph is of function f(x) = (x + 2)^4 + 6 and the parent function g(x) = x^4

The transformed graph function g(x) was shifted two (2) units to the left and was translated six (6) units upward.

When the function is shifted to the right, the factor of x will be negative and when it's shifted to the left, the factor of x will be positive.

Therefore, function g(x) = x^4 is shifted 2 units to the left and translated 6 units upward to form f(x) = ( x + 2 )^4 + 6.

By mathematical induction, we have proved that for any positive integer n, 4 evenly divides 11n - 7n.

WHat is Divisibility?

Divisibility is a mathematical property that describes whether one number can be divided evenly by another number without leaving a remainder. If a number is divisible by another number, it means that the division process results in a whole number without any remainder. For example, 15 is divisible by 3

To prove that 4 evenly divides 11n - 7n for any positive integer n, we can use mathematical induction.

Base Case:

When n = 1, 11n - 7n = 11(1) - 7(1) = 4, which is divisible by 4.

Inductive Step:

Assume that 4 evenly divides 11n - 7n for some positive integer k, i.e., 11k - 7k is divisible by 4.

We need to prove that 4 evenly divides 11(k+1) - 7(k+1), which is (11k + 11) - (7k + 7) = (11k - 7k) + (11 - 7) = 4k + 4.

Since 4 evenly divides 4k, and 4 evenly divides 4, it follows that 4 evenly divides 4k + 4.

By mathematical induction, we have proved that for any positive integer n, 4 evenly divides 11n - 7n.

Step-by-step explanation:

\( \sf{Let \: CP \: ( \: cost \: price) \: be \: x}\)

\( \sf{Loss \: \% \: = 5 \% \: }\)

\( \sf{Selling \: price = CP \: - \: loss \: \% \: of \: CP}\)

\( \mapsto{ \sf x - \frac{5}{100} \times x}\)

\( \mapsto{ \sf{x - \frac{x}{20} }}\)

\( \mapsto{ \sf{ \frac{x \times 20 - x}{20} }}\)

\( \mapsto{ \sf{ \frac{20x - x}{20}}} \)

\( \mapsto{ \sf{ \frac{19x}{20}}} \)

Now, Finding the New selling price

\( \sf{New \: SP \: ( \: selling \: price)} = \frac{19x}{20} + 5200\)

\( \mapsto{ \sf{ \frac{19x + 5200 \times 20}{20}}} \)

\( \mapsto{ \sf{ \frac{19x + 10400}{20}}} \)

Finally, finding the Cost price :

We have, Profit % = 8 %

\( \sf{Cost \: price = Selling \: price \: - \: P\% \: of \: CP}\)

\( \mapsto{ \sf{x = \frac{19x + 104000}{20} - 8\% \: of \: x}}\)

\( \mapsto{ \sf{x = \frac{19x + 104000}{20} - \frac{8x}{100} }}\)

\( \mapsto{ \sf{x = \frac{19x + 104000}{20} - \frac{2x}{25} }}\)

\( \mapsto{ \sf{x = \frac{5(19x + 104000) - 2x \times 4}{100} }}\)

\( \mapsto{ \sf{x = \frac{95x + 520000 - 8x}{100} }}\)

\( \mapsto{ \sf{x = \frac{87x + 520000}{100}}} \)

\( \mapsto{ \sf{100x = 87x + 520000}} \: \: ( \sf{Cross \: multiplication}\)
