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.

The measure of the angles is 143°

From the given diagram, the given measures are alternate exterior angles and they are equal.

Given the following parameters

∠A =7x + 24

∠B = 3x + 92

Equate

7x + 24 = 3x + 92

7x - 3x = 92 - 24

4x = 68

x = 17

Determine the measure of the angles

∠A = ∠B = 7x + 24

∠A = ∠B = 7(17) + 24

∠A = ∠B = 143 degrees

Hence the measure of the angles is 143°

Using the distributive property [tex]\frac{4}{9}[/tex] times 2 equals [tex]\frac{8}{9}[/tex] and [tex]\frac{4}{9}[/tex] times 3 equals [tex]\frac{4}{3}[/tex] which simplifies to [tex]1\frac{1}{3}[/tex]

Answer:

To find the 9th term of a geometric sequence, we can use the formula:

an = a1 * r^(n-1)

where:

an = the nth term of the sequence

a1 = the first term of the sequence

r = the common ratio of the sequence

n = the term number we want to find

In this case, we are given that the common ratio is 2/3, the first term is 6, and we want to find the 9th term. So we can plug in those values and get:

a9 = 6 * (2/3)^(9-1)

Simplifying the exponent, we get:

a9 = 6 * (2/3)^8

Using a calculator, we can evaluate the exponent:

a9 = 6 * 0.015625

Multiplying, we get:

a9 = 0.09375

Therefore, the 9th term of the geometric sequence is 0.09375.

Step-by-step explanation:

here's a step-by-step explanation:

We are given the first term of the geometric sequence, a1 = 6, and the common ratio, r = 2/3. We need to find the 9th term, which we can do using the formula:

an = a1 * r^(n-1)

where n is the term number we want to find.

Step 1: Substitute the given values into the formula

a9 = 6 * (2/3)^(9-1)

Step 2: Simplify the exponent

a9 = 6 * (2/3)^8

The exponent 9-1 simplifies to 8.

Step 3: Evaluate the exponent

a9 = 6 * 0.015625

We can use a calculator to evaluate (2/3)^8, which is 0.015625.

Step 4: Multiply to find the 9th term

a9 = 0.09375

Multiplying 6 by 0.015625 gives us the 9th term of the geometric sequence, which is 0.09375.

Therefore, the 9th term of the geometric sequence whose common ratio is 2/3 and whose first term is 6 is 0.09375.

Answer:

[tex]y=-\frac{2}{3}x+2[/tex]

Step-by-step explanation:

The formula for equation of a line is [tex]y=mx+b[/tex] where m is the slope, b is the y-intercept, and (x,y) can represent any point on the line. We calculate the slope using [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. We are subtracting the y-coordinates in the numerator and the x-coordinates in the denominator.

[tex]\frac{0-2}{3-0} = -\frac{2}{3}[/tex]

You can subtract the coordinates of your second point from your first point and you will get the same slope. Just be sure not to mix up the order.

Now that we have our slope, we can either pull the y-intercept off the graph; the line crosses the y-axis as y = 2, or we can solve our equation for the value of b.

We can pick any point on the line to solve for b. It is recommended to use one of the intercepts because either the x or y component will be zeroed out. I will use the point (0,2)

[tex]y = mx + b\\y = -\frac{2}{3}x +b\\2 = (-\frac{2}{3})(0) + b\\b = 2[/tex]

Now we have all the parts of our equation in slope-intercept form.

[tex]y = -\frac{2}{3}x +2[/tex]

A) the annual rate of change between 1991 and 2000 is -$3,000.

B)  the correct answer to part A in percentage form is -6.67%.
C) where n is the number of years from 2000 to 2003, which is 3, $8,450. approximately.

A) The total change in value between 1991 and 2000 is $45,000 - $12,000 = $33,000. The number of years between 1991 and 2000 is 9. Therefore, the annual rate of change is:

r = (final value - initial value) / (number of years)

r = ($12,000 - $45,000) / 9

r = -$3,000 per year

Thus, the annual rate of change between 1991 and 2000 is -$3,000.

B) To convert the rate of change to percentage form, we need to divide it by the initial value and multiply by 100:

r = (-$3,000 / $45,000) * 100%

r = -6.67%

Therefore, the correct answer to part A in percentage form is -6.67%.

C) If the value continues to drop by the same percentage, we can use the following formula to find the value in 2003:

value = initial value * (1 + r)^n

where n is the number of years from 2000 to 2003, which is 3. Plugging in the values, we get:

value = $12,000 * (1 - 0.0667)^3

what's the best way to recreate the incident as it happened and to picture

The equation for the relationship between the total fee and vertical distance is: y = 100 + x/3000.

Vertical distance is the measurement of the straight line distance between two points in a vertical plane. It is the difference between the higher and lower altitudes of two points and is measured in a straight line from the highest point to the lowest point.

This equation can be explained as follows. The total fee for a trip to climb Mount Kilimanjaro is split into two parts. The first part is the initial fee of $100, which is a fixed cost independent of the distance climbed. The second part is the cost per vertical meter, which is calculated by dividing the vertical distance climbed (x) by 3000 (the constant fee for each vertical meter climbed) and then multiplying the result by the constant fee. Therefore, the equation for the relationship between the total fee and vertical distance is y = 100 + x/3000.

Step-by-step explanation:

To determine the mean number of water tanks supplied to the construction site in March 2022 during weekdays, we need to add up the number of tanks supplied during weekdays and divide by the number of weekdays in March 2022:

March 2022 had 23 weekdays.

From the information given, we don't know the number of tanks supplied during weekdays in March 2022. Therefore, we cannot calculate the mean number of tanks supplied during weekdays in March 2022.

The numerical data recorded on the calendar in ANNEXURE A by the contractor was the number of water tankers supplied to the construction site on each day of the month.

To determine the modal number of water tankers that were supplied to the construction site in June 2022, we need to find the number that appears most frequently in the data:

From the information given, we don't have the data on the number of water tankers supplied to the construction site in June 2022. Therefore, we cannot determine the modal number of water tankers supplied in June 2022.

Given that the water tanker has a fuel capacity of 460 litres and the rate of fuel consumption of the Mercedes water tanker averages 5 km/l, we can calculate the distance traveled on a full tank of fuel:

The distance traveled on a full tank of fuel is 460 litres x 5 km/l = 2,300 km.

Finally, we are given the prices of fuel per litre in March and June 2022:

The quotient gives (f/g)(4) = -16/3 and the value that is not in the domain is x = 1.

Here we know that:

f(x) = (x + 4)(x - 6)

g(x) = x - 1

And we want to find the quotient between these functions:

(f/g)(4)

So first let's find the values of the functions when x = 4.

f(4) = (4 + 4)*(4 - 6) = 8*-2 = -16

g(4) = 4 - 1 = 3

Then the quotient is:

(f/g)(4) = -16/3

Answer:

B

Step-by-step explanation:

The function that models the situation is an exponential decay function of the form:

t(m) = a(1 - r)^m

where:

t(m) is the number of trees after m months

a is the initial number of trees (5,500 in this case)

r is the monthly rate of decrease (3.2% or 0.032 as a decimal)

Substituting the values given in the options, we get:

A) t(m) = 5,500(0.032)^m

B) t(m) = 5,500(1-0.032)^m = 5,500(0.968)^m

C) t(m) = 5,500(1.032)^m

D) t(m) = 5,500(1-0.968)^m = 5,500(0.032)^m

Option B is the correct answer as it correctly models the situation with exponential decay with a starting value of 5,500 trees and a monthly rate of decrease of 3.2%.

Answer: The formula for exponential decay is given by:

t(m) = a(1-r)^m

where

a = initial value

r = decay rate

Here, the initial value is 5,500 and the monthly decay rate is 3.2% or 0.032. So the function that can be used to find the number of trees in the forest at the end of m months is:

t(m) = 5,500(1 - 0.032)^m

t(m) = 5,500(0.968)^m

Therefore, the answer is (D) t(m) = 5,500(0.968)^m.

Through the given statement we can say that the vertical distance travelled by the ball  is 84 m.

One limitation of this model is that it assumes that the ball rebounds to the same percentage of its previous maximum height after every bounce.

The formula for vertical distance from the earth is y = - 1 2 g t 2 y = - frac 1 2 g t 2 y=-21gt2, where g is the acceleration of gravity and h is an elevation.

So :

C) the required total vertical distance that the given dropped ball travels until its bouncing stops:

= (12 m) + 2*(12 m)*(3/4)*[1 + 3/4 + (3/4)^2 + (3/4)^∞] [the factor 2 is for equal distance being covered up and down after each bounce of the ball]

= (12 m) + (24 m)*(3/4)*

(sum of an infinite GP series whose 1st term is 1 and common ratio is 3/4)

= (12 m) + (24 m)*(3/4)*[1/(1 - 3/4)]

= (12 m) + (24 m)*(3/4)*4

= (12 m) + (72m) = 84 m

D) This model's assumption that the ball will always bounce back to a certain proportion of its maximum height is one of its limitations. In fact, the rebound height can differ from one bounce to the next due to factors like air resistance, the ball's elasticity, and the surface it bounces on.

By solving the increase in percentage, the projected number of students in an associate degree program in 2024-2025 is approximately 7,897,500.

What is an increase in percentage?

An increase in percentage is a measure of the change in a quantity expressed as a percentage of the initial value. It is calculated by subtracting the initial value from the final value, dividing the result by the initial value, and then multiplying the quotient by 100 to express the result as a percentage. The formula for calculating the percentage increase is:

percentage increase = (final value - initial value) / initial value * 100

To find the increase in the number of students enrolled in an associate degree program from 2014-2015 to 2024-2025, we can first calculate the amount of increase as a percentage of the initial enrollment:

Increase = 21.5% * 6,500,000 = 1,397,500

Therefore, the increase in the number of students is approximately 1,397,500.

To find the projected number of students in an associate degree program in 2024-2025, we can add the increase to the initial enrollment:

Projected enrollment = 6,500,000 + 1,397,500 = 7,897,500

Therefore, the projected number of students in an associate degree program in 2024-2025 is approximately 7,897,500.

Answer: To find the height of the ramp, we need to use the Pythagorean theorem, which relates the lengths of the sides of a right triangle. In this case, the ramp, porch, and ground form a right triangle, with the height of the ramp being the missing side.

We know that the ramp begins 96 centimeters from the porch and is 100 centimeters long. Let's represent the height of the ramp with the variable "h". Then, we can write the Pythagorean theorem equation:

h^2 + 96^2 = 100^2

Simplifying this equation, we get:

h^2 + 9216 = 10000

Subtracting 9216 from both sides, we get:

h^2 = 784

Taking the square root of both sides, we get:

h = 28

Therefore, the height of the ramp is 28 centimeters.
