The area of the circle is 63.62 square meters

To work out the area of a circle, we need to use the formula A = πr^2, where A is the area of the circle, π is a mathematical constant approximately equal to 3.142, and r is the radius of the circle.

In this problem, we are given the diameter of the circle, which is the distance across the circle passing through its center. The radius is half of the diameter, so we can find it by dividing the diameter by 2.

In this case, the diameter is 9 meters, so the radius is 9/2 = 4.5 meters. We then substitute this value into the formula:

A = πr^2

A = 3.142 x (4.5)^2

A = 3.142 x 20.25

A = 63.6175

A ≈ 63.62 square meters

The solution to the system of linear equations -1.2x+0.3y=-8.4 -1.4x+0.2y=10.6, is x = -27 and y = -136.

The given system of linear equations is:

-1.2x+0.3y=-8.4
-1.4x+0.2y=10.6

To determine whether the system has a solution, we can use the method of elimination. First, we need to multiply each equation by a constant to make the coefficients of one of the variables the same in both equations. In this case, we can multiply the first equation by 2 and the second equation by 3 to make the coefficients of y the same:

-2.4x+0.6y=-16.8
-4.2x+0.6y=31.8

Next, we can subtract the second equation from the first equation to eliminate the y variable:

1.8x=-48.6

Finally, we can solve for x:

x=-27

Now we can plug this value of x back into one of the original equations to solve for y:

-1.2(-27)+0.3y=-8.4
32.4+0.3y=-8.4
0.3y=-40.8
y=-136

So the solution to the system of linear equations is x=-27 and y=-136. Therefore, the given system of linear equations does have a solution.

Answer:

We know that cot A = adjacent side / opposite side = 21/20.

Let x be the length of the adjacent side and y be the length of the opposite side.

Using the Pythagorean theorem, we have:

x^2 + y^2 = (20k)^2, where k is some positive constant.

Since angle A is in Quadrant I, x is positive and y is positive. Thus, we can take the square root of both sides to get:

x + y = 20k.

Now, we can use the fact that cot A = adjacent side / opposite side = 21/20 to get:

x/y = 21/20.

Multiplying both sides by y, we get:

x = (21/20)y.

Substituting this into x + y = 20k, we get:

(21/20)y + y = 20k

Simplifying, we get:

(41/20)y = 20k

y = (20k)/(41/20) = (400k)/41

Now, we can use the Pythagorean theorem to find x:

x^2 + y^2 = (20k)^2

(21/20)y^2 + y^2 = (20k)^2

(441/400)y^2 = (20k)^2

y^2 = (400/441)(20k)^2

y = (20k/441)sqrt(441 x 20)

y = (20k/21)sqrt(20)

Therefore, angle A in simplest radical form using a rational denominator is given by:

tan A = y/x = [(20k/21)sqrt(20)] / [(21/20)y] = sqrt(20)/21

A = arctan(sqrt(20)/21)

To find out how many minutes it would take Teresa to run 9 miles at the same rate, we can use a proportion.

We know that Teresa took 44 minutes to run 6 miles. This means she was running at a rate of 6 miles per 44 minutes. To solve for how long it would take to run 9 miles, we can set up a proportion with this information.

Let x = the number of minutes it would take Teresa to run 9 miles.

6/44 = 9/x

Cross-multiply to solve for x: 44x = 54

Divide both sides by 44 to find the solution: x = 54/44 = 1.227 minutes

Therefore, it would take Teresa 1.227 minutes to run 9 miles at the same rate.

1) The sale price on the painting is $1,235.

2) The regular price of the mechanic's tool set is $340.

3) The regular price of the battery is $111.84.

1) To find the sale price on a painting that has a regular price of $1,900 and is on sale for 35% off the regular price, we can use the formula: sale price = regular price - (regular price * discount rate).
In this case, the sale price would be $1,900 - ($1,900 * 0.35) = $1,900 - $665 = $1,235.
So the sale price of the painting is $1,235.

2) To find the regular price of a mechanic's tool set that is on sale for $204 after a markdown of 40% off the regular price, we can use the formula: regular price = sale price / (1 - discount rate).
In this case, the regular price would be $204 / (1 - 0.40) = $204 / 0.60 = $340.
So the regular price of the mechanic's tool set is $340.

3) To find the regular price of a battery that has a discount price of $85 and is on sale for 24% off the regular price, we can use the formula: regular price = sale price / (1 - discount rate).
In this case, the regular price would be $85 / (1 - 0.24) = $85 / 0.76 = $111.84.
So the regular price of the battery is $111.84.

The velocity of the bird is approximately 40.04 km/hour.

What is velocity ?

Velocity is a measure of the rate at which an object changes its position in a particular direction. It is a vector quantity, which means that it has both a magnitude (speed) and a direction.

To find the velocity of the bird, we can use the formula:

velocity = distance/time

Given that the bird flies 961 km in 24 hours, we can substitute these values into the formula:\

velocity = 961 km / 24 hours

Simplifying this expression, we get:

velocity = 40.04 km/hour (rounded to two decimal places)

Therefore, the velocity of the bird is approximately 40.04 km/hour.

If Lindsay he mows the lawn in 10 hours and with his brother Grant he does it in 2 hours, Grant would mow the lawn alone in 2.5 hours.

To find out how long it would take Grant to mow the lawn alone, we can use the formula for combined work:

1/t₁ + 1/t₂ = 1/ttotal

Where t₁ is the time it takes Lindsay to mow the lawn alone, t₂ is the time it takes Grant to mow the lawn alone, and ttotal is the time it takes both of them to mow the lawn together.

Plugging in the given values:

1/10 + 1/t₂ = 1/2

Multiplying both sides by 20t₂ to clear the fractions:

2t₂ + 20 = 10t₂

Rearranging and simplifying:
8t₂ = 20
t₂ = 20/8
t₂ = 2.5

Answer: :)

Step-by-step explanation:

To classify the triangle as acute, right, or obtuse, we need to determine the measure of the largest angle in the triangle. We can use the Law of Cosines to find the angles of the triangle:

c^2 = a^2 + b^2 - 2ab cos(C)

where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

For this triangle, we have:

c = 12

a = 6

b = 9

Using these values in the Law of Cosines, we get:

12^2 = 6^2 + 9^2 - 2(6)(9)cos(C)

144 = 117 - 108cos(C)

27 = 108cos(C)

cos(C) = 0.25

To find angle C, we can take the inverse cosine (cos^-1) of both sides:

C = cos^-1(0.25)

C ≈ 75.5°

Now we can classify the triangle based on its largest angle:

- If C is less than 90 degrees, then the triangle is acute.

- If C is exactly 90 degrees, then the triangle is right.

- If C is greater than 90 degrees, then the triangle is obtuse.

In this case, since C ≈ 75.5°, which is less than 90 degrees, we know that this triangle is an acute triangle.

The final answer is:

4C+2D = [28 28]
       [14 26]

To find 4C+2D, we first need to multiply the matrices C and D by their respective scalars, 4 and 2. Then, we add the resulting matrices together.

First, let's multiply matrix C by 4:

4C = 4[5 3] = [20 12]
   [1 2]   [ 4  8]

Next, let's multiply matrix D by 2:

2D = 2[4 8] = [ 8 16]
   [5 9]   [10 18]

Now, we can add the resulting matrices together:

4C+2D = [20 12] + [ 8 16] = [28 28]
       [ 4  8]   [10 18]   [14 26]

So, the final answer is:

4C+2D = [28 28]

The distribution of Sn + Tm is a binomial distribution with parameters (n+m, p).

This can be proved using the fact that the sum of independent binomial random variables follows a binomial distribution with the sum of the number of trials and the same probability of success.



Let X ~ Binomial(n, p) and Y ~ Binomial(m, p) be independent random variables representing the number of heads in the first n coin tosses and the last m coin tosses, respectively.

Then, the sum of X and Y, Z = X + Y, follows a binomial distribution with parameters (n+m, p).

The probability mass function of Z can be written as:

P(Z = k) = P(X + Y = k) = ∑ P(X = i) * P(Y = k-i) for i = 0 to k

Since X and Y are independent, we can write:

P(Z = k) = ∑ P(X = i) * P(Y = k-i) = ∑ (n choose i) * p^i * (1-p)^(n-i) * (m choose k-i) * p^(k-i) * (1-p)^(m-k+i)

Simplifying the above equation, we get:

P(Z = k) = (n+m choose k) * p^k * (1-p)^(n+m-k)

Therefore, Z ~ Binomial(n+m, p).

As a result, the distribution of Sn + Tm has the parameters (n+m, p) of a binomial distribution.
