From the question, we have the following parameters that can be used in our computation:

The blue and the red lines

For the blue line, we have the following points

(0, 2) and (-2, 0)

The equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 2

Using the points, we have

-2m + 2 = 0

m = 1

So, we have

y = x + 2

The lower part is shaded and the line is a dotted line

So, we have

y < x + 2

For the red line, we have the following points

(0, 2) and (5, 0)

The equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 2

Using the points, we have

5m + 2 = 0

m = -2/5

Answer:

Step-by-step explanation:

We can start by setting up an equation to solve for x, the number of years it will take for the car to be worth $8,200:

8200 = 20000(0.8)^x

Dividing both sides by 20,000, we get:

0.41 = 0.8^x

Taking the logarithm of both sides (using any base, as long as we're consistent), we get:

log(0.41) = log(0.8^x)

Using the property of logarithms that allows us to bring down the exponent as a coefficient, we get:

log(0.41) = x log(0.8)

Dividing both sides by log(0.8), we get:

x = log(0.41) / log(0.8)

Using a calculator, we find:

x ≈ 5.92

Therefore, it will take about 5.92 years for the car to be worth $8,200.

What is Associative Property ?

The associative property is a mathematical principle that states that the way in which factors are grouped in a multiplication or addition expression does not affect the final result. In other words, when using the associative property, we can add or multiply a group of numbers in any order we want, as long as we keep the order of the individual numbers the same.

(7 + 3) + 2 = 2 + (7 + 3)      Commutative property of addition

3(2x +4) = 6x + 12              Distributive Property

(9 * x) * 3 = 9 * (x * 3)         Associative Property of Multiplication

The second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 and the value of 5.00 the correct answer is {0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}

A histogram is a graph used to represent the frequency distribution of a few data points of one variable. Histograms often classify data into various “bins” or “range groups” and count how many data points belong to each of those bins.

The histogram shows the number of items sold at various price ranges, and the heights of the bars indicate the number of items sold within each price range.

The data set that is represented in the histogram is:

{0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}

This is because the histogram has four bars with heights of 2, 4, 0, and 1, which correspond to the number of items sold in each of the four price ranges shown.

The values in the data set correspond to the boundaries of these price ranges. For example, the first bar represents the price range from $0.00 to $2.50, so the data set includes the value 2.00 (which is within this range) and the value 2.52 (which is just outside this range).

Similarly, the second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 (which is within this range) and the value of 5.00 (which is the upper boundary of this range).

Therefore, the second bar represents the price range from $2.51 to $5.00, so the data set includes the value of 4.53 and the value of 5.00 the correct answer is {0.50, 2.00, 2.52, 3.37, 4.53, 5.00, 8.99}

The price per pound of the carrots Dora bought is $0.80.

What is the unit rate?

Unit rate is a ratio that compares the amount of one unit of measure to the corresponding amount of another unit of measure. It is a special case of a ratio, in which the second term is always one. For example, if a car travels 120 miles in 2 hours, the unit rate of speed is 60 miles per hour, which means that the car travels 60 miles for every hour of driving.

Unit rate is commonly used in everyday life, such as in shopping (price per unit) or in cooking (ingredients per serving).

To find the price per pound of the carrots, we need to divide the total cost by the total weight.

First, we need to convert the mixed number 4 1/2 to an improper fraction:

4 1/2 = (4 x 2 + 1) / 2 = 9/2

Next, we divide the total cost by the total weight in pounds:

Price per pound = Total cost / Total weight

Price per pound = $3.60 / 4.5 pounds

Price per pound = $0.80

Therefore, the price per pound of the carrots Dora bought is $0.80.

The area of the composite figure is approximately 57.51 square centimeters.

By calculating the area of the triangle and the sector, and then adding them together, we may determine the area of the composite figure.

The following formula can be used to determine the sector's area:

Sector area is equal to (central angle / 360) x r2.

The sector's radius is 8 cm, and its central angle is 60°, resulting in:

Sector area equals (60/360) x 3.14 x 82

Sector size: 33.51

The following formula can be used to get the triangle's area:

Area of triangle Equals base x height x half.

The Pythagorean theorem can be used to determine the triangle's height given that its base is 8 cm:

a² + b² = c²

8² + h² = 10²

64 + h² = 100

h² = 36

h = 6

As a result, given that the triangle's height is 6 cm, we have:

Triangle's area equals 1/2 x 8 x 6.

Triangle has a 24 area.

By combining the areas of the triangle and the sector, we can determine the area of the composite figure.

33.51 + 24 times the composite figure's area

Answer:

Step-by-step explanation:

Ana's conjecture that Raul lost 2/5 of his baby teeth is true.

To see why, consider that Raul originally had 20 baby teeth. If he lost 8 of these teeth, that means he has 20 - 8 = 12 baby teeth remaining. To determine what fraction of his baby teeth he lost, we can calculate:

8 baby teeth lost / 20 baby teeth total = 2/5

So, Raul lost 2/5 of his baby teeth, which supports Ana's conjecture.

On the other hand, Raul's statement that he lost 4/10 of his baby teeth is not correct, since 4/10 can be simplified to 2/5, which is the same as Ana's conjecture that he lost 2/5 of his baby teeth.

a. The six trigonometric functions of the angle β are:

sin β = 7/25

cos β = 24/25

tan β = 7/24

csc β = 25/7

sec β = 25/24

cot β = 24/7

b. Using trigonometric identity, cos X + (sin X)(tan X) = 1

We can use the given value of cos β = 24/25 to find the other trigonometric functions of the angle β.

Let's draw a right triangle with angle β, adjacent side of length 24, and hypotenuse of length 25 (since cos β = adjacent/hypotenuse):

Using the Pythagorean theorem, we can find the opposite side:

Opposite side = sqrt(hypotenuse^2 - adjacent^2) = sqrt(25^2 - 24^2) = sqrt(49) = 7

So the triangle is:

Now we can find the other trigonometric functions:

sin β = opposite/hypotenuse = 7/25

cos β = adjacent/hypotenuse = 24/25

tan β = opposite/adjacent = 7/24

csc β = hypotenuse/opposite = 25/7

sec β = hypotenuse/adjacent = 25/24

cot β = adjacent/opposite = 24/7

2. We can use the trigonometric identity for tangent:

tan X = sin X / cos X

to rewrite the expression as:

cos X + (sin X)(sin X / cos X)

Multiplying through by cos X, we get:

(cos X)(cos X) + (sin X)(sin X)

Using the Pythagorean identity:

(sin X)^2 + (cos X)^2 = 1

we can simplify further:

1 - (cos X)^2 + (cos X)^2 = 1

So the final simplified expression is equal to 1

3. We can start with the left-hand side of the equation and manipulate it using the definitions of the trigonometric functions and the Pythagorean identity until we arrive at the right-hand side:

tan²α(csc²α - 1)

= (sin²α/cos²α)((1/sin²α) - 1)

= (sin²α/cos²α - sin²α/cos²α)

= 0

Now, let's look at the right-hand side:

1

We see that the left-hand side simplifies to 0, while the right-hand side is 1. Therefore, the identity is not true for all values of α.

We can see this more clearly by picking a specific value of α and evaluating both sides of the equation. For example, let's take α = 45°:

tan²45°(csc²45° - 1) = (1/1)((2/1) - 1) = 1

1 = 1

So the identity holds for α = 45°, but we have already shown that it does not hold for all values of α. Therefore, the identity is not true for all values of α.

What is average rate ?

Average rate refers to the rate of change of a quantity over a given period of time. It is calculated by dividing the change in the quantity by the time period over which the change occurs.

To find the average rate of change in cost per class, we need to calculate the slope of the linear function that relates the gym fee to the number of classes taken.

Let x be the number of classes taken, and y be the gym fee. We can use the two data points given to find the equation of the line:

When x = 6, y = 43

When x = 11, y = 73

The slope of the line passing through these two points can be calculated as follows:

slope = (change in y) / (change in x)

slope = (73 - 43) / (11 - 6)

slope = 30 / 5

slope = 6

The line's slope is [tex]\frac{1}{2}[/tex] and the distance increases by 1 mile every 2 hours.

What is a good example of a line's slope?

The proportion of the increase in the y-value to the increase in the x-value may also be used to determine slope. For instance: We can get the slope of a line given two locations, P = (0, -1) & Q = (4,1) on the line.

A. Since the line's slope is 2, it follows that the y-variable, which is most likely distance, grows by 2 units for every increment in the x-variable, which is most likely time. The accurate statement is thus: speed is increased by Two miles per hour.

B. Since the line's slope is 2, it follows that the y-variable will drop by 2 units for every unit rise in the x-variable, which is most likely time. The accurate description is thus: speed drops by Two miles per hour.

C. If the line's slope is 1/2, the y-variable will rise by 1/2 unit for every increment in the x-variable, which is probably time. The precise description is that the distance grows by a mile every two hours.
