Answer:

x = 21

Upper angle has a measure of 69°

Lower angle has a measure of 21°

Step-by-step explanation:

The two angles form a right angle ( indicated by the little square )

A right angle has a measure of 90 degrees.

This means that (x + 48) + x must equal 90

Note that we've just created an equation that we can use to solve for x

We now solve for x using that equation

x + 48 + x = 90

combine like terms

2x + 48 = 90

subtract 48 from both sides

2x = 42

divide both sides by 2

x = 21

We then plug in x to find the measures of the angles

x + 48

x = 21

21 + 48

= 69

The other angle simply equals 21°

Answer:

x = 21°

(x + 48°) = 69=

Step-by-step explanation:

x + 48° + x = 90°

2x +48° = 90° Subtract 48° in both sides

2x = 42° Divide both sides by 2:

x = 21°

a. The market equilibrium price can be found by setting the quantity demanded equal to the quantity supplied. In this case, we have Pd = Ps, so we can set -10Qd + 80 = 2Qs + 20. Solving for Qs, we get Qs = (60 + 10Qd)/2.

b. To find the market equilibrium quantity, we substitute the value of Qs into the equation for Ps: Ps = 2Qs + 20. Plugging in the value of Qs, we get Ps = (60 + 10Qd)/2 + 20. Simplifying this equation, we find Ps = (30 + 5Qd) + 20, which simplifies further to Ps = 50 + 5Qd.

c. Consumer surplus represents the difference between the price consumers are willing to pay and the market equilibrium price. To calculate the consumer surplus, we need to find the area of the triangle above the market equilibrium quantity and below the demand curve. In this case, the demand curve equation is Pd = -10Qd + 80.

d. Producer surplus represents the difference between the market equilibrium price and the price producers are willing to sell at. To calculate the producer surplus, we need to find the area of the triangle below the market equilibrium quantity and above the supply curve. In this case, the supply curve equation is Ps = 2Qs + 20.

e. Total surplus is the sum of the consumer surplus and the producer surplus.

f. To graph the market, we can plot the demand and supply curves on a graph with price on the y-axis and quantity on the x-axis. We can label the equilibrium price and quantity as the point where the demand and supply curves intersect. The consumer surplus and producer surplus can be represented by shaded areas on the graph.

The specific values for the market equilibrium price, quantity, consumer surplus, producer surplus, and total surplus cannot be determined without additional information or values for Qd.

In each scenario, the choice between mean and median as a representative measure of central tendency depends on the nature of the data and the specific context..

1. Scenario: Income distribution of a population

- If the income distribution is skewed or contains extreme values (outliers), the median would be a better representation of the central tendency. This is because the median is not influenced by outliers and provides a more robust estimate of the "typical" income level. However, if the income distribution is approximately symmetric without outliers, the mean can also be an appropriate measure.

2. Scenario: Exam scores in a class

- If the exam scores are normally distributed without significant outliers, the mean would be a suitable measure as it takes into account the value of each score. However, if there are extreme scores that deviate from the majority of the data, the median may be a better representation. This is especially true if the outliers are indicative of errors or exceptional circumstances.

3. Scenario: Housing prices in a city

- In this case, the median would be a more appropriate measure to represent the central tendency of housing prices. This is because the housing market often exhibits a skewed distribution with a few high-priced properties (outliers). The median, being the middle value when the data is sorted, is not influenced by these extreme values and provides a better understanding of the typical housing price in the city.

Ultimately, the choice between mean and median depends on the specific characteristics of the data and the objective of the analysis. It is important to consider the distribution, presence of outliers, and the context in which the data is being interpreted.

Maria must use 200 milliliters of 10% solution and n 50% solution.

Given that:

Maria needs to mix a 10% fungicide solution with a 50% fungicide solution to create 200 milliliters of a 10% solution.

Let x be the volume of the 10% fungicide solution and y be the volume of the 50% fungicide solution.

Then,

x + y = 200

y = 200 - x. [Equation 1]

Now using the dilution formula:

(C1 x V1) + (C2 x V2) = C3 x V3

Substitute:

10x + 50y = 10 × 200

10x + 50y = 2000 [Equation 2]

Here we get a system of linear equations.

Substitute [Equation 1] in [Equation 2].

10x + 50(200 - x) = 2000

10x + 10000 - 50x = 2000

-40x = -8000

x = 200

The solution to the inequality is all values of x less than 5. We can write the solution set using interval notation as (-∞, 5).

To solve the inequality -5x - 3 + 2x > -18, we need to isolate the variable x on one side of the inequality sign.

Starting with the given inequality:

-5x - 3 + 2x > -18

Simplifying the left-hand side by combining the like terms:

-3x - 3 > -18

Adding 3 to both sides:

-3x > -15

Dividing both sides by -3, and reversing the inequality sign since we are dividing by a negative number:

x < 5

By applying the maximum modulus principle, we found that the maximum value of 2i(z²) + 3 on the set of complex numbers whose modulus is less than or equal to 1 is √13.

Let's start by expressing the given function in terms of z. We have:

f(z) = 2i(z²) + 3

Now, let's consider the modulus of f(z):

|f(z)| = |2i(z²) + 3|

According to the maximum modulus principle, the maximum value of |f(z)| occurs on the boundary of the given domain, which is the circle of radius 1 centered at the origin in the complex plane.

In order to find the maximum value, we need to evaluate |f(z)| on the boundary of the circle |z| = 1.

Let's substitute z = 1 into f(z):

f(1) = 2i(1²) + 3

= 2i + 3

Taking the modulus of f(1):

|f(1)| = |2i + 3|

To find the maximum value, we need to determine the magnitude of the complex number 2i + 3. The modulus (or magnitude) of a complex number a + bi, denoted as |a + bi|, is given by:

|a + bi| = √(a² + b²)

For the complex number 2i + 3, we have:

|2i + 3| = √(2² + 3²)

= √(4 + 9)

= √13

Therefore, the maximum value of |f(z)| occurs at |z| = 1 and is equal to √13.

If the cost for using 21 HCF of water is $35.39.  the cost for using 56 HCF of water is  $82.64.

We can use the two given data points to find the slope and y-intercept of the linear function that represents the monthly cost of water use.

Let's use (21, 35.39) and (57, 83.99) as our two data points.

First, let's find the slope of the line:

slope = (y2 - y1) / (x2 - x1)

slope = (83.99 - 35.39) / (57 - 21)

slope = 48.6 / 36

slope = 1.35

Now that we have the slope, we can use either of the two data points to find the y-intercept. Let's use (21, 35.39):

y = mx + b

35.39 = 1.35 * 21 + b

35.39 = 28.35 + b

b = 35.39 - 28.35

b = 7.04

So the linear function that represents the monthly cost of water use is:

y = 1.35x + 7.04

where y is the cost (in dollars) and x is the amount of water used (in HCF).

Now we can use this function to find the cost for using 56 HCF of water:

y = 1.35x + 7.04

y = 1.35 * 56 + 7.04

y = 82.64

So the cost for using 56 HCF of water is  $82.64.

The rate of change of the function shown in the graph is $0.5 per minute.

What is rate of change?

The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time. When discussing momentum, the term "rate of change" is frequently used. It is typically defined as the ratio of a change in one variable to a matching change in another; visually, the rate of change is represented by the slope of a line. The Greek letter delta (Δ) is usually come in use to represent the ROC.

As shown in the graph,

The x-axis represents the minute and y-axis represents the cost.

and the cost is function of time.

For each 10 minute the cost increased $5

So, the cost is changing at a rate of $5 per 10 minute

$5 = 10 minutes
