The measure of the side length CL is equal to 9m using trigonometric ratio of cosine 60° for thy right triangle ACL

What are trigonometric ratios

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

Angle m∠BAC = 180° - (m∠C + m∠ABC)

m∠BAC = 180° - (90° + 30°)

m∠BAC = 60°

line AL is an angle bisector so;

m∠CAL = 30° and m∠BAL = 30°

which implies triangle ∆ALB is an isosceles with line LB = AL = 18m

considering the right triangle ∆ACL;

angle m∠L = 180° - (90° + 30°)

m∠L = 60°

cos 60° = CL/18 {adjacent/hypotenuse}

1/2 = CL/18m {cos 60° = 1/2}

CL = 18m/2 {cross multiplication}

CL = 9m

Therefore, the side length CL is equal to 9m using trigonometric ratio of cosine 60° for the right triangle ACL.

f(x) = 4800 * 1.5^x is the equation to model the relationship between the number of weeks, x, and the number of site visits.

It is said that the number of visits increased by a factor of 1.5 each week, which means it multiplied by 1.5 every week.

So the equation can be modeled as:

f(x) = 4800 * 1.5^x

Where x is the number of weeks and f(x) is the number of site visits.

Note that this equation is only valid for the number of weeks after the new marketing plan has been launched, since before that the number of visits was 4,800.

The correct statement is parameter because the value is a numerical measurement describing a characteristic of a population.

A parameter is a numeric value that describes a population feature in probability and statistics. It is a fixed value that is typically unknown and used to define or describe a probability distribution. The population's mean, variance, and standard deviation are a few examples of parameters.

Typically, these parameters are calculated using statistical techniques like maximum likelihood estimation from a sample of data. One can learn something about the entire population from a parameter. In the case of a given question, this implies that after asking everyone in that group, one will know something.

is the system linear or non-linear? you need to justify your answer. b) is the system time-varying or time-invariant? you need to justify your answer. c) is the system causal or not causal? you need to justify your answer. d) find the impulse response function of the system

Answers

The given system is :

a) Linear

b) Time-invariant

c) Casual

d) Impulse response function is h(n) = 2δ(n-1) + δ(n-2).

a) Linear: A system is considered linear if it satisfies the superposition principle, meaning that if the inputs x1(n) and x2(n) produce outputs y1(n) and y2(n), respectively, then the output of the system to a weighted sum of inputs is equal to the weighted sum of the outputs. In this system, 2x(n-1) and x(2n) are both linear operations, and the sum of two linear operations is also a linear operation. Therefore, this system is linear.

b) Time-invariant: A system is considered time-invariant if the output is not dependent on the current time, but only on the input and its previous values. In this system, the coefficients 2 and 1 do not change with time, and the system does not depend on the current time. Therefore, this system is time-invariant.

c) Causal: A system is considered causal if the output only depends on the present and past inputs, and not on future inputs. In this system, x(2n) only depends on the past and present inputs, and x(n-1) only depends on past inputs. Therefore, this system is causal.

d) Impulse response function: The impulse response function of the system can be found by taking the unit impulse as the input, solving for the output and normalizing it.

h(n) = 2δ(n-1) + δ(n-2)

where δ(n) is the unit impulse function and h(n) is the impulse response function of the system.

The measure of the missing length in the figure, found using Pythagorean Theorem is; x = 37 mm

What is Pythagorean Theorem?

Pythagorean Theorem states the relationship between the lengths of the sides of a right triangle. According to Pythagorean Theorem, the sum of the squares of the leg lengths of a right triangle is equivalent to the square of the length of the hypotenuse side.

Please find attached a possible figure in the question, obtained from a similar question posted on the website.

The 13 mm side hypotenuse length of the right triangle on the left  indicates a other leg length of the right triangle can be found using Pythagorean Theorem as follows;

Square of the length of the hypotenuse side = Sum of the square of the length of the other two sides

13² = 5² + (second leg length)²

The second leg length of the right triangle on the left = √(13² - 5²) = 12

The 12 mm leg length of the right triangle on the left indicates that the leg length of the right triangle on the right which correspond with the 12 mm leg length on the left is 12 mm

The length of the hypotenuse of the right triangle on the right, which is the missing length, x is therefore;

x² = 12² + 35² = 1369

What was the initial height that she threw the ball from?

Answers

The initial height of the ball is the y-intercept of the function. The initial height she threw the ball from was 35.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax² + bx + c = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient, and 'c' is called the absolute term of f (x).

The function is as follows:

h(x) = -16x² + 3x + 35

Substitute the value of x = 0.

So, we have:

h(0) = -16(0)² + 3(0) + 35

Evaluate the exponent

h(0) = -16(0) + 3(0) + 35

Evaluate the products

h(0) = 0 + 0 + 35

Evaluate the sum

h(0) = 35

Hence, the initial height she threw the ball from was 35.

The equation of the parabola with the given vertex and y-intercept is:

y = -(x - 3)² + 3

How to Write an Equation of a Parabola with a Given Vertex and Y-intercept?

The equation of a parabola in vertex form is given by:

y = a(x - h)² + k

Where (h, k) is the vertex of the parabola, and a is a nonzero constant. To find the equation of the parabola that satisfies the given conditions, we can use the vertex and the y-intercept to find the values of a, h, and k.

The vertex of the parabola is (3, 3), so h = 3 and k = 3. The y-intercept of the parabola is (0, -6), which means that when x = 0, y = -6. Substituting these values into the equation of the parabola, we get:

y = a(x - 3)² + 3

When x = 0, y = -6. Plugging in the value of x and y, we get

-6 = a(0 - 3)² + 3

-6 = 9a + 3

Answers

If one column of dots on the dot plot is much taller than the others, it means that on that particular day, the restaurant sold significantly more pizzas than on the other days of the week.

A dot plot is a simple graphical representation of data where each data point is represented by a dot or mark above a number line. In this context, the dot plot shows the number of pizzas sold at a local restaurant each day for one week. The height of the column of dots represents the number of pizzas sold on that particular day.

If one column of dots is much taller than the others, it means that on that particular day, the restaurant sold significantly more pizzas than on the other days of the week. This could be due to a variety of reasons such as a special promotion, a holiday, or just a generally busy day.

Understanding which days are the busiest for the restaurant can help the management make decisions such as staffing levels, inventory management, and marketing strategies. For example, if a particular day of the week is consistently the busiest, the restaurant may want to offer a special promotion or discount on that day to attract more customers.

In terms of percents, if for example, the restaurant sold 100 pizzas on the day with the tallest column of dots, and the next highest day sold 60 pizzas, the day with 100 pizzas would be 166.6% higher than the day with 60 pizzas. It indicates the significance of the difference between the two days in terms of sales.

PLEASE HELP

Answers

If David spends $10, he may call for 50 minutes.

As per the data given in the above question are as bellow,

Let x represent the duration of David's phone calls.

The following linear equation can be used to express the call's cost:

Price = x + (x - 3) (0.10)

By setting the equation's value to 10 and finding the value of x, we can determine how long David will talk on the phone if he spends $10:

10 = 0.25x + (x-3)(0.10) (0.10)

The right side of the equation is first made simpler:

10 = 0.25x + 0.10x - 0.30

Next, we may combine related words as follows: 10 = 0.35x - 0.30

10 plus 0.30 equals 0.35x when applied to both sides.

Consequently, x = 50. David talks on the phone for 50 minutes.

A heat source generates heat at a rate of 70. 0 W (1 W = 1J/s). How much entropy does this produce per hour in the

surroundings at 28. 5 °C? Assume the heat transfer is reversible.

Answers

The entropy produced by the heat source is 2.17 J/K per hour.

In order to calculate the amount of entropy produced by a heat source, we need to use the formula for entropy change: ΔS = Q/T,

where Q is the amount of heat transferred and T is the temperature of the surroundings in kelvins.

To convert the temperature to Kelvin, we add 273.15 to the temperature in degrees Celsius.

In this case, the heat source generates 70.0 W of heat and the temperature of the surroundings is 28.5 °C.

So, to find the entropy change per hour, we need to multiply the power generated by the time:

ΔS = (70.0 W) * (3600 s/h) / (28.5+273.15)

This calculation results in approximately 2.17 J/K * h or 2.17 J/K per hour.

Step 7 of 7: Compute the cumulative frequency of the second class.

Answers

In this case, the cumulative frequency of the second class would be the number of prices in the data set that fall within the range of $1150 and $1219 plus the cumulative frequency of the first class.

What is the cumulative frequency?

Cumulative frequency is a running total of the frequencies of a data set. It is used to keep track of how many observations fall within a certain range of values. It is the sum of the frequencies of all the classes up to a certain point.

The second class is 1150-1219 which means it includes the price of refrigerators that fall within the range of $1150 and $1219. To find the cumulative frequency of the second class, you would need to count the number of prices in the data set that fall within that range and add it to the cumulative frequency of the previous class.

In this case, the cumulative frequency of the second class would be the number of prices in the data set that fall within the range of $1150 and $1219 plus the cumulative frequency of the first class. Since the cumulative frequency of the first class is not provided, we cannot calculate the cumulative frequency of the second class without more information.
