Answer:

22π feet

Step-by-step explanation:

Area of circle = π r ²

121π = πr ²

121 = r ²

r = 11.

diameter D = 2r = 22.

Circumference = π X D

= 22π feet

Given:

Point B has coordinates ​(4,1).

The​ x-coordinate of point A is -4.

The distance between point A and point B is 10 units.

To find:

The possible coordinates of point​ A.

Solution:

Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).

Distance formula:

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

The distance between point A and point B is 10 units.

\(\sqrt{(4-(-4))^2+(1-y)^2}=10\)

Taking square on both sides, we get

\((8)^2+(1-y)^2=100\)

\((1-y)^2=100-64\)

\((1-y)^2=36\)

Taking square root on both sides, we get

\((1-y)=\pm \sqrt{36}\)

\(-y=\pm 6-1\)

\(y=1\mp 6\)

\(y=1-6\) and \(y=1+6\)

\(y=-5\) and \(y=7\)

Therefore, the possible coordinates of point​ A are either (-4,-5) or (-4,7).

the total amount of oil that leaks out over the entire time interval [0, 120].

integral ∫₀¹₂₀ r(t) dt represents the total amount of oil that leaks from the tank in 120 minutes.

To see why, consider the definition of an integral. If we divide the interval [0, 120] into small subintervals of width Δt, then the amount of oil that leaks out during each subinterval is approximately r(t)Δt. Summing up all these small amounts over the entire interval gives:

Σᵢ r(tᵢ) Δt

where tᵢ is the midpoint of the i-th subinterval. As we take the limit as the subinterval width goes to zero, this sum becomes the integral:

∫₀¹₂₀ r(t) dt

which represents the total amount of oil that leaks out over the entire time interval [0, 120].

 Two shapes are congruent if they have the same shape and size. We can also say if two shapes are congruent, then the mirror image of one shape is the same as the other.

  Geometric figures that are congruent share the same size and shape. In other words, figures are congruent if they can be transformed into one another through a series of transformations, rotations, and/or reflections. When the sides and angles of two triangles match, the triangles are said to be congruent. 

Triangles that have comparable sides and equal angles are said to be congruent. Indicating congruence is the sign “≅”.

Congruent refers to objects that are exactly the same size and shape. Even if we flip, turn, or revolve the shapes, the shape and size must remain the same.

The sinusoidal equation of the trigonometric function is equal to y = 3 · sin (π · x / 4).

In this problem we find the representation of a trigonometric function on Cartesian plane. This equation can be described by the following sinusoidal equation:

y = b + A · sin (2π · x / T)

Where:

If we know that b = 0, A = 3 and T = 8, then the sinusoidal equation is:

Answer:

m=3.5h

Step-by-step explanation:

Just by looking at this, you know that it won't be either of the adding equations because it only works for the bottom input and output. So, we'll just look at the multiplying ones.

We know that multiplying should get us a bigger number (unless it's a fraction), so the equation h=3.5m won't work very well with this because h would be getting smaller not bigger.

That leaves us with m=3.5h.

To check this, I'll multiply 3.5 by 4 to see if it equals what m is on the table. Sure enough, it's 14. This also works with 2.5 and 8.75.

Never. Correlation does not imply causation. A correlation coefficient based on an observational study can only be used to suggest a relationship between two variables, but it cannot be used to support a claim of cause and effect.

Correlation is a measure of the relationship between two variables. It is used to measure how two variables move together. A correlation coefficient based on an observational study can only be used to suggest a relationship between two variables, but it cannot be used to support a claim of cause and effect. This is because correlation does not imply causation. A correlation coefficient close to -1 or +1 is an indication of a strong linear relationship between the two variables, but this does not necessarily imply a cause-and-effect relationship. Additionally, even if the scatterplot of the data has little vertical variation, this does not guarantee a cause-and-effect relationship. In summary, correlation coefficients based on observational studies can never be used to support a claim of cause and effect.

Therefore, the range of the relation 2x + y = 3 for the given domain {-3, 0, 6} is {9, 3, -9}.

To determine the range of the relation 2x + y = 3 for the given domain {-3, 0, 6}, we need to find the corresponding range values when we substitute each value from the domain into the equation.

Substituting -3 into the equation, we have 2(-3) + y = 3, which simplifies to -6 + y = 3. Solving for y, we get y = 9.

Substituting 0 into the equation, we have 2(0) + y = 3, which simplifies to y = 3.

Substituting 6 into the equation, we have 2(6) + y = 3, which simplifies to 12 + y = 3. Solving for y, we get y = -9.

A method of assigning probabilities based upon personal judgment is referred to as the subjective method. The correct answer is a.

The subjective method of assigning probabilities is based on personal judgment or subjective beliefs about the likelihood of events occurring. It involves incorporating individual knowledge, experience, and intuition to estimate the probabilities of different outcomes.

Unlike the classical method, which assigns probabilities based on equally likely outcomes, or the relative frequency method, which uses observed frequencies to determine probabilities, the subjective method relies on individual opinions and subjective assessments of probabilities.

In the subjective method, probabilities are not determined through mathematical calculations or empirical data. Instead, they are based on an individual's expertise, opinions, and subjective reasoning.

This method is commonly used in situations where objective data or historical information is limited or unavailable, such as in decision-making under uncertainty or when dealing with complex and uncertain scenarios.

It will take 20.6 hours to paint the house if both painter A and painter B worked together.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Let F represent the house fully painted.

Painting done by painter A in 50 hours = F

Painting done by painter A in 1 hour = F/50

Painting done by painter B in 35 hours = F

Painting done by painter B in 1 hour = F/35

If they both paint together,

Painting done by painter A and painter B in 1 hour = F/50 + F/35

                                                                                    = 85/1750 F

                                                                                    = 17/350 F

Time taken to paint 17/350 F = 1 hour

Time taken to paint F = 1 / (17/350)

                                    = 20.588

                                    ≈ 20.6 hours

Hence time taken to paint the house by both working together is 20.6 hours.
