Answer:

a + c = 90° because BC is a tangent to circle A, meaning that angle B is a right angle.

Answer: Range = 22 IQR = 13

Step-by-step explanation:

To find the range of a data set, subtract the largest value of the data set from the smallest value. 45 is the largest value and 23 is the smallest, and 45-23 is 22, so the range is 22. To find the IQR, you must subtract the upper quartile and the lower quartile. We can find this after finding the mean by re-arranging all the values in order from lowest to greatest, and finding the middle value. Once we do so, we get 33.5. Then, we find the median of all the numbers below and after the median to get the lower and upper quartiles. Then, we subtract them to get the IQR 13.

Remember - SOH CAH TOA

cos(A) = adjacent / hypotenuse

adjacent = 5

sin(A) = opposite / hypotenuse

opposite = 12

hypotenuse = 13

tan(A) = opposite / adjacent

tan(A) = 12 / 5

Answer: tan(A) = 12/5

The perimeter of the tree house floor is  27.62 meters and area of the tree house floor is 30 square meters.

To find the perimeter of the tree house floor, we need to add up the lengths of all four sides of the rectangular floor.

We can use the distance formula to calculate the length of each side:

Length of side AB =√(6-0)² + (4-4)²) = √(36) = 6 meters

Length of side BC =√(6-0)² + (-1-4)²) = √61 = 7.81 meters

Length of side CD = √(0-6)² + (-1-4)² = √61= 7.81 meters

Length of side DA = √(0-6)²+ (4-4)²) =√36= 6 meters

Therefore, the perimeter of the tree house floor is:

Perimeter = AB + BC + CD + DA

Perimeter = 6 + 7.81 + 7.81 + 6

Perimeter = 27.62 meters

To find the area of the tree house floor, we can use the formula for the area of a rectangle:

Area = base x height

The base of the rectangle is the length of side AB, which is 6 meters.

The height of the rectangle is the distance between points B and C, which is 4-(-1) = 5 meters. Therefore, the area of the tree house floor is:

Area = base x height

Area = 6 x 5

Area = 30 square meters

Hence, the area of the tree house floor is 30 square meters.

To ensure that you have at least two cards with the same denomination, you would need to draw five cards.

This problem is a variation of the pigeonhole principle, also known as the birthday paradox. There are 13 denominations in a standard deck of cards (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King), and drawing five cards creates five pigeonholes. Since there are more pigeonholes than there are denominations, it is guaranteed that at least two of the cards will have the same denomination. To see this, note that drawing six cards will also guarantee two cards with the same denomination, since there would be six pigeonholes and only 13 denominations.

The volume of the right circular cone with a height of 15.4 m and a base circumference of 18 m is 15.68 cubic meters.

To find the volume of a right circular cone, we can use the formula:

Volume = (1/3) × π × r² × h,

where π is the mathematical constant pi, r is the radius of the base, and h is the height of the cone.

Given that the base has a circumference of 18 m, we can calculate the radius using the formula:

Circumference = 2 × π × r

18 = 2 × π × r

r = 18 / (2 × π) = 2.864 m.

Now we can substitute the values into the volume formula:

Volume = (1/3) × π × (2.864 m)² × 15.4 m,

Volume = 15.68 m³

Therefore, the volume of the right circular cone with a height of 15.4 m and a base circumference of 18 m is 15.68 cubic meters.

For the given function the answer is a + b = 3/2 + 9/2 = 12/2 = 6.

A function is an association between inputs in which each input has a unique link to one or more outputs.

To find the values of a and b, we can substitute the expressions for f(x) and g(x) into the equation g(f(x)) = 3x + 4 and solve for a and b.

We have:

g(f(x)) = 3x + 4

Substituting the expressions for f(x) and g(x), we get:

g(ax + b) = 3x + 4

Since g(x) = 2x - 5, we can replace g(ax + b) with 2(ax + b) - 5:

2(ax + b) - 5 = 3x + 4

Expanding and simplifying, we have:

2ax + 2b - 5 = 3x + 4

Rearranging terms, we get:

(2a - 3)x + (2b - 9) = 0

For this equation to hold for all values of x, the coefficient of x must be zero, and the constant terms must also be zero.

Therefore, we have the following system of equations:

2a - 3 = 0   (coefficient of x)

2b - 9 = 0   (constant term)

Solving these equations simultaneously, we find:

2a = 3   -->   a = 3/2

2b = 9   -->   b = 9/2

Therefore, a + b = 3/2 + 9/2 = 12/2 = 6.

The percentile rank describes the percentage of scores in the frequency distribution that are equal to or lower than the achieved score.

To calculate the percentile rank of a score of 141, we can proceed as follows:

Firstly, the scores are arranged in ascending order: 88, 95, 104, 110, 111, 112, 112, 120, 123, 134, 141, 145, 152, 156, 166, 166, 168, 177, 177, 190.

The number of scores below 141 = 10

The number of scores equal to 141 = 1

The following percentile rank formula can be used to determine the percentile rank of a score of 141:

Percentile Rank = [(M + (0.5 * R)) / Y] x 100, where:

M = Number of Ranks below x

R = Number of Ranks equals x

Y = Total Number of Ranks

Percentile Rank = [(10 + (0.5 * 1)) / 20] x 100

the rate of change of the radius at the instant when the radius is 11 feet and the volume is 26 cubic feet is -10 feet per second.

What is Volume?

Volume is the amount of three-dimensional space enclosed by a closed surface, such as the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using an SI-derived unit, the cubic meter

To find the rate of change of the radius at the instant when the radius of the cylinder is 11 feet and the volume is 26 cubic feet, we can use the related rates of change between the height, radius, and volume of the cylinder.

Let's denote the height of the cylinder as h, the radius as r, and the volume as V. We are given that the height is decreasing at a constant rate of 2 feet per second, and the volume is decreasing at a rate of 264 cubic feet per second.

We know the formula for the volume of a cylinder is V = πr^2h.

Differentiating both sides of the equation with respect to time (t), we have:

dV/dt = d(πr^2h)/dt

Using the product rule, we can rewrite this as:

dV/dt = π(2rh(dr/dt) + r^2(dh/dt))

Since we are given the values of dV/dt (rate of change of volume) and dh/dt (rate of change of height), and we want to find the rate of change of the radius, we can substitute these values into the equation along with the known values of r (radius) and V (volume) at the given instant.

dV/dt = -264 (volume is decreasing at a rate of 264 cubic feet per second)

dh/dt = -2 (height is decreasing at a rate of 2 feet per second)

r = 11 (radius is 11 feet)

V = 26 (volume is 26 cubic feet)

Plugging in these values, we have:

-264 = π(2(11)(dr/dt) + 11^2(-2))

Simplifying further:

-264 = π(22(dr/dt) - 22)

Dividing both sides by π(22), we get:

-12 = dr/dt - 2

Adding 2 to both sides, we have:

dr/dt = -12 + 2 = -10

Therefore, the rate of change of the radius at the instant when the radius is 11 feet and the volume is 26 cubic feet is -10 feet per second. Note that the negative sign indicates that the radius is decreasing.

So, we have:

cos θ = x/1

cos θ = x

Now, the given angle is π/2 radians, and the point P (0, 1) lies on the terminal side of the angle. From the point P (0, 1), we can move left towards the origin to make a right-angled triangle.

Since the angle measures π/2, one leg will be on the x-axis (the horizontal leg) and the other leg will be on the y-axis (the vertical leg). Let's construct a right triangle using the point P (0, 1) and the origin (0,0) as two of the vertices: So, the opposite side is equal to 0, and the adjacent side is equal to 1.

The X-Coordinate of 3 only represents a specific moment in time during the orbit and not necessarily the speed of the ISS at all times.

Since the graph is showing how fast the International Space Station (ISS) is traveling in orbit around the Earth, the x-coordinate of 3 likely represents a specific point in time or duration of the orbit.

To find out what the x-coordinate of 3 represents, we need to know the units of time on the x-axis. If the units are in minutes, then a value of 3 would represent 3 minutes. Similarly, if the units are in hours, then a value of 3 would represent 3 hours.

Assuming the units on the x-axis are in minutes, the point with an x-coordinate of 3 represents the speed of the ISS 3 minutes into its orbit. This means that at that point in time, the ISS was traveling at a speed of approximately 27,500 kilometers per hour.

It's important to note that the speed of the ISS can vary throughout its orbit, depending on factors such as altitude, atmospheric conditions, and changes in the orbit itself. Therefore, the x-coordinate of 3 only represents a specific moment in time during the orbit and not necessarily the speed of the ISS at all times.

The general solution of the differential equation is: y = c1 e^(3t) cos(t) + c2 e^(3t) sin(t), where c1 and c2 are arbitrary constants determined by the initial or boundary conditions.

The given differential equation is a second-order homogeneous linear differential equation with constant coefficients. Its characteristic equation is obtained by assuming a solution of the form y = e^(rt), where r is a constant. Substituting this into the differential equation, we get:

r^2 e^(rt) - 6r e^(rt) + 10 e^(rt) = 0

Dividing both sides by e^(rt) (which is non-zero), we get:

r^2 - 6r + 10 = 0

Solving for r using the quadratic formula, we get:

r = (6 ± sqrt(6^2 - 4(1)(10))) / 2

r = 3 ± i

Therefore, the general solution of the differential equation is:

y = c1 e^(3t) cos(t) + c2 e^(3t) sin(t)

where c1 and c2 are arbitrary constants determined by the initial or boundary conditions.

This solution consists of a linear combination of two functions: the exponential function e^(3t) and the periodic function cos(t) or sin(t), which oscillates between -1 and 1. The exponential function represents the growth or decay of the system, while the periodic function represents the oscillations or vibrations of the system. The constants c1 and c2 determine the amplitude and phase of the oscillations, respectively. The behavior of the system depends on the signs and magnitudes of the real and imaginary parts of the roots, which determine whether the solutions are overdamped, critically damped, or underdamped.

the above numbers (Saturday or Sunday) the true probability is closer to. Inverse correlation implies that as the probability of shopping on Saturday increases, the probability of shopping on Sunday decreases, and vice versa.

If the probability of shopping on Saturday is inversely correlated with the probability of shopping on Sunday, we can infer that as the likelihood of shopping on one day increases, the likelihood of shopping on the other day decreases.

Without specific numbers or additional information, it is impossible to determine which probability is closer to the true probability.

Let's consider two scenarios to illustrate this point.

In Scenario A, the probability of shopping on Saturday is high (e.g., 80%), suggesting a low probability of shopping on Sunday (e.g., 20%).

In Scenario B, the probability of shopping on Saturday is low (e.g., 20%), indicating a high probability of shopping on Sunday (e.g., 80%).

Both scenarios exhibit an inverse correlation between the two probabilities.

In Scenario A, the true probability is closer to 80% for shopping on Saturday, while in Scenario B, the true probability is closer to 80% for shopping on Sunday.

Thus, without specific values or additional information, it is not possible to determine which probability is closer to the true probability.

To determine how the golfer ended in terms of par, tally up all of her scores and deduct them from the total par for the seven rounds.

The total par for seven rounds multiply by eighteen is 126 (assuming the course is a regular par 72).

The golfer's score in relation to par for each round is:

1 round at 3 over par = 75 (72 + 3)

2 rounds with 1 over par = 73 (72 + 1) x 2 = 146

3 rounds with 3 under par = 69 (72 - 3) x 3 = 207

1 round at 1 under par = 71 (72 - 1)
