Both angles on the parallel lines are related as ∠1=180°-∠7

Vertical angles, also known as vertically opposed angles, are generated when two lines intersect. Angles that are vertically opposite one another are always equal to one another. Moreover, a vertical angle and the angle to which it is next are supplementary angles, meaning their sum is 180 degrees.

To find: measure ∠1 through ∠7

∠7=∠5 ( vertically opposite angle)

∠5=∠2( co-exterior angle)

∠1+∠2=180°

( A straight line has a maximum angle of 180°.)

∠1=180°-∠2

∠1=180°-∠5

∠1=180°-∠7

Plane takeoff angle.

Angel

During take off, a plane leaves the ground and travels in a straight line until it reaches a height of 10 km. The distance the plane flies during take off should be in the range 57 km to 62 km. What is the smallest possible angle that the path of the plane could make with the ground? Give your answer in degrees to 1 d. p.

Let's assume that the plane travels a distance of x km during take off and reaches a height of 10 km. Then, using trigonometry, we can find the angle θ between the ground and the path of the plane:

tan(θ) = 10/x

We want to find the smallest possible angle θ, which means we need to maximize x. From the given information, we know that x must be in the range 57 km to 62 km. Therefore, to maximize x, we choose x = 62 km.

Plugging this into the equation above, we get:

tan(θ) = 10/62

θ = arctan(10/62) ≈ 8.8°

Therefore, the smallest possible angle that the path of the plane could make with the ground is approximately 8.8 degrees.

Xochitl spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead. The plane maintains a constant altitude of 7425 feet. Xochitl initially measures an angle of elevation of 19° to the plane at point A. At some later time, she measures an angle of elevation of 37° to the plane at point B.

Find the distance the plane traveled from point A to point B. Round your answer to the nearest foot if necessary

Let's assume that the distance from Xochitl to point A is d1 and the distance from Xochitl to point B is d2. We want to find the distance the plane traveled from point A to point B, which is the difference between d1 and d2.

From the given information, we can set up the following two equations:

tan(19°) = 7425/d1

tan(37°) = 7425/d2

Solving for d1 and d2, we get:

d1 = 7425/tan(19°) ≈ 22977.6 feet

d2 = 7425/tan(37°) ≈ 13060.2 feet

Therefore, the distance the plane traveled from point A to point B is:

d1 - d2 ≈ 9917.4 feet ≈ 3021 meters

Rounding to the nearest foot, we get that the distance the plane traveled from point A to point B is approximately 9917 feet.

Plane B is flying 75mph 75 ⁢ mph faster than Plane A. Find the time it takes for Plane A to travel 2300 2300 miles if it takes Plane B the same amount of time to travel 2600 2600 miles.

Let's start by using the formula for distance, rate, and time:

distance = rate x time

Let's assume that Plane A's speed is r mph. Then we know that Plane B's speed is r + 75 mph.

We also know that Plane A travels 2300 miles and Plane B travels 2600 miles. Since they take the same amount of time to travel their respective distances, we can set up the following equation:

2300/r = 2600/(r + 75)

To solve for r, we can cross-multiply and simplify:

2300(r + 75) = 2600r

2300r + 172500 = 2600r

300r = 172500

r = 575 mph

Now that we know Plane A's speed, we can use the formula for distance, rate, and time to find the time it takes for Plane A to travel 2300 miles:

distance = rate x time

2300 = 575 x time

time = 4 hours

The five-number summary for data and construct a box plot is: 59, 62, 65, 70, 77
The IQR for the data is 8.

What is median ?

The median is a measure of central tendency in statistics. It is the value separating the higher half from the lower half of a data sample. To find the median of a data set, the data is first arranged in ascending or descending order, and then the middle value is identified. If the data set has an odd number of values, the middle value is the median. If the data set has an even number of values, the median is the average of the two middle values. The median is a useful measure of central tendency when the data contains outliers or extreme values that may affect the mean.

According to the question:
a. The five-number summary consists of the minimum, lower quartile (Q1), median (Q2), upper quartile (Q3), and maximum. To find these values:

Minimum: 59

Q1: the median of the lower half of the data, which is the median of the first 20 values (when ordered from smallest to largest): (62 + 62) / 2 = 62

Median (Q2): the middle value when the data is ordered from smallest to largest: (65 + 65) / 2 = 65

Q3: the median of the upper half of the data, which is the median of the last 20 values: (70 + 70) / 2 = 70

Maximum: 77

Therefore, the five-number summary is: 59, 62, 65, 70, 77

To construct a box plot, we can draw a number line and mark the five-number summary points. We then draw a box from Q1 to Q3, with a line at the median (Q2) inside the box. Finally, we draw whiskers from the box to the minimum and maximum values, unless there are outliers that are more than 1.5 times the interquartile range (IQR) away from the box.

b. The interquartile range (IQR) is the difference between the upper and lower quartiles, or Q3 - Q1. From part (a), we have Q1 = 62 and Q3 = 70, so:

IQR = Q3 - Q1 = 70 - 62 = 8

Therefore, the IQR for the data is 8.

The slope of the line that best suits the data is -0.1463.

slope = [tex]\sum (( x -\bar x )( y - \bar y )) / \sum ( x - \bar x ) ^2[/tex]

where x is the number of ice cream treats sold, y is the number of coffee drinks sold, x bar is the mean of the number of ice cream treats sold, and ȳ is the mean of the number of coffee drinks sold.

Using the given data, we find that:

[tex]\bar x =[/tex] (16 + 19 + 28 + 27 + 28 + 36 + 38 + 41 + 41 + 48) / 10 = 32.2

[tex]\bar y =[/tex] (55 + 43 + 51 + 46 + 32 + 36 + 43 + 25 + 10 + 33) / 10 = 36.4

Next, we calculate the terms needed for the formula:

[tex]\sum (( x - \bar x )( y - \bar y ))[/tex] = (16 - 32.2)(55 - 36.4) + (19 - 32.2)(43 - 36.4) + ... + (48 - 32.2)(33 - 36.4) = -686.6

[tex]\sum ( x - \bar x )^2[/tex] = (16 - 32.2)² + (19 - 32.2)² + ... + (48 - 32.2)² = 4690.6

Plugging these values into the formula, we get:

slope = [tex]\sum (( x - \bar x )( y - \bar y )) / \sum ( x - \bar x )^2[/tex] = -686.6 / 4690.6 = -0.1463

Therefore, the slope of the line that best fits the data is -0.1463.

Interpreting the slope in terms of the situation, we can say that for every additional ice cream treat sold, the number of coffee drinks sold decreases by an average of 0.1463.

To write the equation of the line that best fits the data, we use the slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept. We already know the value of m, so we just need to find b. To do this, we can use the mean values of x and y:

y = mx + b

36.4 = (-0.1463)(32.2) + b

b = 41.9

Therefore, the equation of the line that best fits the data is:

y = -0.1463x + 41.9

To estimate the number of coffee drinks sold on a day that 32 ice cream treats were sold using the equation of the line of best fit, we simply substitute x = 32 into the equation and solve for y:

y = -0.1463(32) + 41.9

y ≈ 36.9

So we can estimate that approximately 36.9 coffee drinks were sold on a day that 32 ice cream treats were sold. This conclusion is justified because we used the equation of the line that best fits the data to make the estimate, which takes into account the overall trend of the data and the relationship between the number of ice cream treats sold and the number of coffee drinks sold. However, it's important to note that this is only an estimate and there may be other factors that could affect the actual number of coffee drinks sold on a particular day.

x + y = 8 → (2)

add the 2 equations term by term to eliminate y

(x + x) + (y - y) = 8 + 4

2x + 0 = 12

2x = 12 ( divide both sides by 2 )

x = 6

substitute x = 6 into (2) and solve for y

6 + y = 8 ( subtract 6 from both sides )

y = 2

the system has one solution , that is (6, 2 )

0 + (-66) Plus 18 = -48 is indeed the common sum for every one of these pairings. Hence, -48 is the solution.

The total of the first n terms in the arithmetic sequence is equal to the sum (addition) of the n terms in AP. It is equal to n split by 2 times total sum of thrice the first term, "a," and the product of difference between the second and first term, "d," also; known as the common difference, plus (n-1), where n is the number of terms to be added.

The following step is to add -62 to all of the three remaining integers to create three new ones: -62 + (-4) (= -66, -62 Plus (-2) = -64, & -62 plus 80 = 18. From these three numbers, we now need to select two pairs that sum up to the same number.

We are able to observe that -66 plus -64 is -130, therefore the answer is 18. We obtain 148 when we multiply 130 by 18. As a result, the following three sets of numbers add up to a single total:

The equation of the line is y=-4x+9. In order to find the equation of the line, we must first calculate the slope (m) of the line.

Slope is a measure of the steepness of a line on a graph. It is calculated by finding the ratio of the vertical change between two points, divided by the horizontal change between the same two points.

The slope is calculated by dividing the change in y-coordinates (rise) by the change in x-coordinates (run).

In this case, the rise is -5 – (-9) = 4, and the run is 1 – 0 = 1. Therefore, the slope of the line is m = 4/1 = 4.

Next, we plug the slope and a point on the line into the point-slope form of a line equation: y - y1 = m(x - x1).

We can choose any point on the line, so let's use (0, -9).

Plugging in the values, we get:

y - (-9) = 4(x - 0)

Simplifying, we get:

y = 4x - 9

Therefore, the equation of the line is y = 4x - 9.

Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread. An exponential function has the following form at its most fundamental level.

f(x) = [tex]a^{x}[/tex]

Exponential equation for the amount of Caffeine

C = 80[tex](2)^{-t/6}[/tex]

Amount of caffeine C = 60 mg.

60 = 80[tex](2)^{-t/6}[/tex]

3/4 = [tex](2)^{-t/6}[/tex]

Taking log on both sise:

[tex]log_{2}(3/4) = -t/6[/tex]

Solve the log function using the log calculator:

-t/6 = (-0.41)

t = 0.41 * 6

t = 2.46 hours

Thus, the time taken to drop the caffeine from 80 mg to 60 mg is 2.46 hours.
