Answer:

34.65 mi²

Step-by-step explanation:

Area of parallelogramam = b · h

b = 6.3 mi

h = 5.5 mi

Let's solve

6.3 · 5.5 = 34.65 mi²

So, the area of the shape is 34.65 mi²

The paper airplane will not hit the ground within the given time frame.

To find the equation for h( t), we need to find the rate of change or the  pitch of the function. We can do this by chancing  the difference in height and time for any two points on the line. Let's choose the first two points,( 0,200) and( 1,208).  

pitch = ( change in height)/( change in time)  

pitch = ( 208- 200)/( 1- 0) =  8  

So, the equation for h( t) can be written in  pitch- intercept form as   h( t) =  8t b  

To find the value of b, we can use any of the given points.

Let's use( 0,200)   200 =  8( 0) b  b =  200  

So, the equation for h( t) is   h( t) =  8t 200  

To find how long it'll take the aeroplane to hit the ground, we need to find when h( t) =  0,

since that would mean the height is 0  bases or the ground  position.   0 =  8t 200   working for t,

we get   t = -25

Since time cannot be negative the paper airplane will not hit the ground within the given time frame.

Answer: Therefore, the length of a blue bead is 2.5 cm, and the length of a green bead is 1.2 cm. And the length of the bracelet is:

10 × (2.5 + 1.2) = 37 cm.

Step-by-step explanation:

To represent the length of the bracelet, we need to determine the length of each repetition of the basic pattern and then multiply it by the number of times the pattern is repeated.

The length of each repetition of the basic pattern is the sum of the length of one blue bead and one green bead, which is:

B + 1.2 cm

Since the basic pattern is repeated 10 times, the total length of the bracelet is:

10 × (B + 1.2) cm

And we know that the total length of the bracelet is 37 cm, so we can set up an equation:

10 × (B + 1.2) = 37

Simplifying the equation, we can divide both sides by 10:

B + 1.2 = 3.7

Subtracting 1.2 from both sides, we get:

B = 2.5

Therefore, the length of a blue bead is 2.5 cm, and the length of a green bead is 1.2 cm. And the length of the bracelet is:

10 × (2.5 + 1.2) = 37 cm.

If a large airline wants to estimate its average number of unoccupied seats per flight over the past year Then a 92% confidence interval for the population mean number of unoccupied seats per flight is (10.334, 12.266) seats.

To construct a confidence interval for the population mean number of unoccupied seats per flight, we will use the following formula CI = X ± z*(σ/√n)

Where:

X = sample mean = 11.3 seats

σ = sample standard deviation = 4.3 seats

n = sample size = 300

z = z-score corresponding to the desired confidence level of 92%, which we can look up in a standard normal distribution table or use a calculator. For a 92% confidence level, the z-score is 1.75.

Plugging in the values, we get:

CI = 11.3 ± 1.75*(4.3/√300)

CI = 11.3 ± 0.966

Therefore, the 92% confidence interval for the population mean number of unoccupied seats per flight is (10.334, 12.266) seats. This means we can be 92% confident that the true population means a number of unoccupied seats per flight falls within this interval.

Since OX is perpendicular to PQ, and OY is perpendicular to RS, we know that OX and OY are both radii of the circle. Therefore, we can write:

OX = OY

This is because all radii of a circle are equal in length. Alternatively, we could also say that OX and OY are both the distance from the center O to the respective lines PQ and RS. Since PQ=RS, OX and OY are equal in length.

In a circle, the center is the point from which all points on the circumference are equidistant. This means that any line segment from the center to a point on the circle is a radius of the circle.

In this problem, we have two lines PQ and RS, both of which are tangent to the circle at points P and R respectively. We also have two lines OX and OY, each of which is perpendicular to one of the tangent lines.

Because the tangent lines are perpendicular to their respective radii (PQ is perpendicular to OX, and RS is perpendicular to OY), we can conclude that OX and OY are both radii of the circle, and therefore, they have the same length.

Note that both are still angles at 90 degrees.

Anallency will have $134.46 more money than Alejandro after one year of their respective deposits.

Alejandro and Anallency are depositing money in separate accounts with different interest rates. Alejandro is depositing $1,750 in an account that earns a simple interest rate of 6.5% per year, while Anallency is depositing $1,675 in an account that earns a compounded interest rate of 7.5% per year. After one year of their respective deposits, Anallency will have $134.46 more money than Alejandro.

The difference in interest earned between the two accounts is the reason for the difference in money earned by Alejandro and Anallency. Alejandro's account earns a simple interest rate, which means that he earns 6.5% of his initial deposit every year, regardless of how much interest he has already earned.

On the other hand, Anallency's account earns a compounded interest rate, which means that she earns interest on both her initial deposit and on any interest earned in previous years.

The formula for calculating simple interest is I = Prt, where I is the interest earned, P is the principal (or initial deposit), r is the interest rate, and t is the time in years. Using this formula, we can calculate that Alejandro will earn $113.75 in interest after one year.

The formula for calculating compounded interest is A = P(1 + r/n)^(nt), where A is the amount of money at the end of the time period, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

The speed of the faster car is 90 kph and the speed of the slower car is 45 kph.

We are given that two cars are starting together and they travel in the same direction. Let one car be car A and the other car B. Speed of car B is twice the speed of car A. Let r be the rate of speed of car A and 2r be the rate of speed of car B.

We know that these two cars are 225 km apart. We will use the formula distance = speed * time. Let the distance car A travels after 5 hours be 5r. So, the distance traveled by car B after 5 hours will be 5(2r) = 10r.

Since car B is faster, it will have traveled farther after 5 hours. Therefore,

Distance traveled by car B - distance traveled by car A = 225

10r - 5r = 225

The woman performed 100 joules of work to push the cart of groceries over a distance of 10 meters.

To find the work performed by the woman, we will use the work-energy theorem which states that work (W) is equal to the change in energy. In this case, the woman applies a 10 Newton force and uses 100 joules of energy. The formula for work is:

W = F × d × cos(θ)

Where W is work, F is force, d is the distance over which the force is applied, and θ is the angle between the force and the direction of motion. Since the woman used 100 joules of energy, we can rewrite the equation as:

100 J = 10 N × d × cos(θ)

We don't have information about the angle θ, but if we assume that she applied the force horizontally, which is in the same direction as the motion, the angle θ would be 0 degrees, and the cosine of 0 is 1. Therefore, the equation becomes:

100 J = 10 N × d

To find the distance (d), we can now solve for d:

d = 100 J / 10 N

d = 10 meters

So, 100 joules of work was performed by the women to push the cart of groceries over a distance of 10 meters.

The top of the ladder is moving down the wall at a rate of 32/3 feet per second when the bottom of the ladder is 8 feet from the wall.

Let's denote the distance between the bottom of the ladder and the wall as x, and the distance between the top of the ladder and the ground as y. Since the ladder is leaning against the wall, we have a right triangle formed by the ladder, the wall, and the ground.

We know that the ladder has a length of 10 feet, so by the Pythagorean theorem, we have:

x^2 + y^2 = 10^2

Differentiating both sides with respect to time t, we get:

2x(dx/dt) + 2y(dy/dt) = 0

We want to find the rate of change of y (the speed at which the top of the ladder is moving down the wall), when x = 8 ft and dx/dt = 8 ft/s. We can substitute these values into the equation above and solve for dy/dt:

2(8)(8) + 2y(dy/dt) = 0

Simplifying this equation, we get:

dy/dt = -64/y

Now we need to find the value of y when x = 8 ft. We can use the Pythagorean theorem again:

x^2 + y^2 = 10^2

8^2 + y^2 = 100

y^2 = 100 - 64

y = sqrt(36) = 6 ft

Substituting this value of y into our equation for dy/dt, we get:

dy/dt = -64/6 = -32/3 ft/s

Now, use the function y = f(x) = 9x to find the y values:
y = 9(3) = 27 (for x = 3)
y = 9(3.03) = 27.27 (for x = 3.03)

b) To find dy, we first need to find the derivative of the function (f'(x)). The function is y = f(x) = 9x, and its derivative (using differentiation) is:
