What is the length of OP?

Answer: x + 3x = 11

Step-by-step explanation:

Two cities A and B

Both cities receive 11 inches of rainfall in total

Amount of Rainfall in inches received by city A = x

Amount of Rainfall in inches received by city B = 3x

Therefore given the details above, total rainfall is best expressed using the equation ;

Rainfall in city A + Rainfall in city B = 11 inches

x + 3x = 11

Step-by-step explanation:

The storm is expected to affect an area of approximately 484 square kilometers.

To calculate the area that the storm will affect, we can use the formula for the area of a circle, which is πr² (pi times the radius squared). If the storm is expected to hit 11 km in every direction from the small town, then the radius of the affected area is 11 km.

Substituting the radius value into the formula, we get:

π(11 km)² = π(121 km²) ≈ 380.1327 km²

However, since the storm is expected to affect the area in every direction, we need to multiply the calculated area by 4 to get the total area that the storm will affect.

4 x 380.1327 km² ≈ 1520.5308 km²

Therefore, the storm is expected to affect an area of approximately 1520.5308 square kilometers, or 484 square kilometers rounded to the nearest whole number.

If the rank of matrix A is equal to the number of columns of A, and the rank of matrix A is equal to the rank of the augmented matrix [A|b], then the system Ax = b will have a unique solution for all choices of b. Otherwise, the system Ax = b will not have a unique solution for all choices of b.

To determine if the system ax = b has a solution for all choices of b, we need to look at the rank of the matrix A and the rank of the matrix formed by appending the vector b to the matrix A.

The rank of a matrix is the number of linearly independent rows or columns in the matrix. If the rank of matrix A is equal to the number of columns in A, then matrix A is full rank and the system Ax = b will have a unique solution for all choices of b. If the rank of matrix A is less than the number of columns in A, then matrix A is not full rank, and the system Ax = b will not have a unique solution for all choices of b.

If the rank of matrix A is equal to the rank of the matrix formed by appending the vector b to matrix A, the system Ax = b will have a unique solution for all choices of b.

Given

Volume of baby pool = 52ft³

Required

Determine the volume of the medium pool

Volume of a cylinder is calculated as:

\(V = \pi r^2h\)

Hence, the volume of the baby pool is:

\(\pi r^2h = 52\)

where r and h are the radius and height of the baby pool

Represent the height and radius of the medium pool as H and R

From the given parameters in the question

\(H = 4 * h\) and \(R = 4 * r\)

\(H = 4 h\) and \(R = 4 r\)

The volume of the medium cylinder is calculated as

\(Volume = \pi R^2H\)

Substitute 4h for H and 4r for R

\(Volume = \pi (4r)^2(4h)\)

Open bracket

\(Volume = \pi (4r) * (4r) * (4h)\)

\(Volume = \pi 16r^2 * (4h)\)

\(Volume = \pi 16r^2 * 4h\)

Collect like terms

\(Volume = \pi r^2 * h * 4 * 16\)

\(Volume = \pi r^2 h * 64\)

Recall that \(\pi r^2h = 52\)

So, the expression becomes

\(Volume = 52 * 64\)

\(Volume = 3328\)

Hence, the medium pool can hold \(3328ft^3\) of water

The result of (3+4i)^20 is -1,072,697,779,282,031 + 98,867,629,664,588i.

To find the value of (3+4i)^20, we can use the concept of De Moivre's theorem. According to De Moivre's theorem, (a+bi)^n can be expressed as (r^n) * (cos(nθ) + i*sin(nθ)), where r is the magnitude of a+bi and θ is the angle it forms with the positive real axis.

In this case, a = 3 and b = 4, so the magnitude r can be calculated as √(a^2 + b^2) = √(3^2 + 4^2) = √(9 + 16) = √25 = 5. The angle θ can be found using the inverse tangent function, tan^(-1)(b/a) = tan^(-1)(4/3) ≈ 53.13 degrees (or ≈ 0.93 radians).

Now, we can express (3+4i)^20 as (5^20) * [cos(20*0.93) + i*sin(20*0.93)]. Evaluating this expression, we get (5^20) * [cos(18.6) + i*sin(18.6)].

Since cos(18.6) ≈ -0.9165 and sin(18.6) ≈ 0.3999, we can simplify the expression to (5^20) * (-0.9165 + 0.3999i).

Finally, calculating (5^20) = 9,536,743,164,062,500, we can substitute this value back into the expression and obtain the final result of -1,072,697,779,282,031 + 98,867,629,664,588i.

The length of the third side of an isosceles triangle is 9 cm.

Define isosceles triangle.

A triangle with two sides that are congruent or that are the same length is known as an isosceles triangle.

Define perimeter.

The sum of the lengths of the three sides of an isosceles triangle can be used to determine its perimeter. Two of the sides of an isosceles triangle are equal in length. Therefore, if we know the base length and the other two equal side lengths, we can determine the perimeter.

Given data -

Perimeter of an isosceles triangle  = 47cm

The sum of the equal sides = 38 cm

Let a be the length of equal sides.

Therefore 2a = 38

Perimeter of an isosceles triangle = 2a + b

47 = 38 + b

b = 47 - 38

b = 9 cm

The value of cos2x when sine of x equals negative 15 over 17 and cos x > 0 is -161/289.

The ratio of the neighboring side's length to the longest side, or hypotenuse, in a right triangle is known as the cosine. Let's say that the hypotenuse of a triangle ABC is written as AB, and the angle between the hypotenuse and base is written as.

It's interesting to see that cos's value varies depending on the quadrant. As observed in the above table, cos 0°, 30°, etc. have positive values while cos 120°, 150°, and 180° have negative values. Cos will have a good value in the first and fourth quadrants.

Given that, sin x equals negative 15 over 17.

Using the Pythagoras theorem we have:

(17)² = (- 15)² + y²

y = 8

The value of cos x = 8/17

Then the value of cos2(x) is calculated using the formula:

cos2x = cos²x - sin²x

cos2x = (8/17)² - (15/17)²

cos2x = -161/289

Hence, the value of cos2x when sine of x equals negative 15 over 17 and cos x > 0 is -161/289.
