Answer:

The square roots of 49·i in ascending order are;

1) -7·(cos(45°) + i·sin(45°))

2) 7·(cos(45°) + i·sin(45°))

Step-by-step explanation:

The square root of complex numbers 49·i is found as follows;

x + y·i = r·(cosθ + i·sinθ)

Where;

r = √(x² + y²)

θ = arctan(y/x)

Therefore;

49·i = 0 + 49·i

Therefore, we have;

r = √(0² + 49²) = 49

θ = arctan(49/0) → 90°

Therefore, we have;

49·i = 49·(cos(90°) + i·sin(90°)

By De Moivre's formula, we have;

\(r \cdot (cos(\theta) + i \cdot sin(\theta) )^{\dfrac{1}{2}} = \pm \sqrt{r} \cdot \left (cos\left (\dfrac{\theta}{2} \right ) + i \cdot sin\left (\dfrac{\theta}{2} \right ) \right )\)

Therefore;

√(49·i) = √(49·(cos(90°) + i·sin(90°)) = ± √49·(cos(90°/2) + i·sin(90°/2))

∴ √(49·i) = ± √49·(cos(90°/2) + i·sin(90°/2)) = ± 7·(cos(45°) + i·sin(45°))

√(49·i) = ± 7·(cos(45°) + i·sin(45°))

The square roots of 49·i in ascending order are;

√(49·i) = - 7·(cos(45°) + i·sin(45°))  and  7·(cos(45°) + i·sin(45°))

Answer:

about 24.38 feet

Step-by-step explanation:

Graphing window: [0, 30] by [-20, 160]

y1 = 20 + 2x + √(400 + 4x^2)

y2 = 1.6(20 + x + √(400 + x^2))

y1 = y2 when x = 24.3798.

So the length of the smaller garden's longer leg is about 24.38 feet.

1. Let μ₁ be the population mean salary of safeties, and μ₂ be the population mean salary of linebackers.

2. Null hypothesis (H0): μ1 = μ2 (There is no difference between the average pay of safeties and linebackers.)

Alternative hypothesis (H1): μ1 ≠ μ2 (There is a difference between the average pay of safeties and linebackers.)

3. For safeties: n₁ = 15, \(\bar{X_1}\) = $501,580, σ₁ = $20,000

For linebackers: n₂ = 15,\(\bar{X_2}\) = $513,360, σ₂ = $18,000

4. We will use the two-sample t-test for independent samples to test the hypothesis.

5. the critical t-value is approximately ±2.763.

6. the test statistic (t-value) is - 1.680

7. the calculated t-value (-1.680) does not fall within the critical region of ±2.763, we fail to reject the null hypothesis.

1. Define:

Let μ₁ be the population mean salary of safeties, and μ₂ be the population mean salary of linebackers.

Let \(\bar{X_1}\) be the sample mean salary of safeties, \(\bar{X_2}\) be the sample mean salary of linebackers.

Let n₁ be the sample size of safeties (15), n₂ be the sample size of linebackers (15).

Let σ₁ be the standard deviation of safeties ($20,000), and σ₂ be the standard deviation of linebackers ($18,000).

2. Hypothesis:

Null hypothesis (H0): μ1 = μ2 (There is no difference between the average pay of safeties and linebackers.)

Alternative hypothesis (H1): μ1 ≠ μ2 (There is a difference between the average pay of safeties and linebackers.)

3. Sample:

For safeties: n₁ = 15, \(\bar{X_1}\) = $501,580, σ₁ = $20,000

For linebackers: n₂ = 15,\(\bar{X_2}\) = $513,360, σ₂ = $18,000

4. Test:

We will use the two-sample t-test for independent samples to test the hypothesis.

5. Critical Region:

Since the significance level (α) is given as 0.01, we will use a two-tailed test.

Using a t-table or t-distribution calculator with α/2 = 0.01/2 = 0.005 and degrees of freedom df = n₁ + n₂ - 2 = 15 + 15 - 2 = 28, the critical t-value is approximately ±2.763.

6. Computation:

Calculate the test statistic (t-value) using the formula:

t = (\(\bar{X_1}-\bar{X_2}\)) / √((σ₁² / n₁) + (σ₂² / n₂))

t = ($501,580 - $513,360) / √((($20,000²) / 15) + (($18,000²) / 15))

t = -11680 / √((400000000 / 15) + (324000000 / 15))

t ≈ -11680 / √(26666666.67 + 21600000)

t ≈ -11680 / √(48266666.67)

t ≈ -11680 / 6949.89

t ≈ -1.680

7. Decision:

Since the calculated t-value (-1.680) does not fall within the critical region of ±2.763, we fail to reject the null hypothesis. Therefore, based on the sample data, we do not have sufficient evidence to conclude that there is a significant difference between the average pay of safeties and linebackers in the Pro League.

Step-by-step explanation:

The absolute minimum value of f(x, y) is -16, occurring at the points (7, 0) and (7, 10). Therefore, the minimum value is -16.

To find the absolute minimum and absolute maximum of the function f(x, y) = 6 - 4x + 7y on the closed triangular region with vertices (0, 0), (7, 0), and (7, 10), we need to evaluate the function at the critical points and the boundary of the region.

Critical points: To find critical points, we need to take the partial derivatives of f(x, y) with respect to x and y and set them equal to zero.

∂f/∂x = -4 = 0

∂f/∂y = 7 = 0

Since there are no solutions to these equations, there are no critical points within the region.

Boundary of the region: We need to evaluate the function at the vertices and on the sides of the triangle.

Vertices:

f(0, 0) = 6 - 4(0) + 7(0) = 6

f(7, 0) = 6 - 4(7) + 7(0) = -16

f(7, 10) = 6 - 4(7) + 7(10) = 60

Sides:

Side 1: From (0, 0) to (7, 0)

y = 0

f(x, 0) = 6 - 4x + 7(0) = 6 - 4x

The minimum occurs at x = 7 with a value of -16.

Side 2: From (0, 0) to (7, 10)

y = (10/7)x

f(x, (10/7)x) = 6 - 4x + 7((10/7)x) = 6 - 4x + 10x = 6 + 6x

The minimum occurs at x = 0 with a value of 6.

Side 3: From (7, 0) to (7, 10)

x = 7

f(7, y) = 6 - 4(7) + 7y = -22 + 7y

The minimum occurs at y = 0 with a value of -22.

From the above evaluations, we can conclude:

The absolute minimum value of f(x, y) is -16, occurring at the points (7, 0) and (7, 10).

The absolute maximum value of f(x, y) is 60, occurring at the point (7, 10).

Therefore, the minimum value is -16.

This is a translation of 2 units to the left and 5 units up, so the correct option is the first one.,

Remember that a vertical translation of N units is:

g(x) = f(x) + N

if N < 0 the translation is down.

if N > 0 the translation is up.

And a horizontal translation of N units is:

g(x) = f(x + N)

If N > 0 the translation is to the right.

if N < 0 the translation is to the left.

Here we have the transformation:

f(x) = x²

g(x) = (x + 2)² + 5

Coterminal angles are those whose ultimate positions are identical but whose number of full revolutions varies.

No, coterminal angles have the same angle measure. Two angles are coterminal if they have the same initial side and the same terminal side, meaning that they differ by an integer multiple of 360 degrees (or 2π radians) or by a multiple of 360 degrees plus or minus any number of full rotations (i.e., adding or subtracting 360 degrees or 2π radians any number of times).

For example, 30 degrees and 390 degrees are coterminal angles because 390 - 30 = 360, which is a multiple of 360 degrees. Similarly, 45 degrees and 405 degrees are coterminal because 405 - 45 = 360

However, two angles that differ by a non-integer multiple of 360 degrees are not coterminal. For example, 30 degrees and 390.5 degrees are not coterminal because they differ by 360.5 degrees, which is not a multiple of 360 degrees.

The proof of cosec(2A) + cot(4A) = cot(A) - cosec(4A)  is shown below.

Using the trigonometric identities:

cosec(θ) = 1/sin(θ)

cot(θ) = 1/tan(θ) = cos(θ)/sin(θ)

We can rewrite the equation as:

1/sin(2A) + cos(4A)/sin(4A) = cos(A)/sin(A) - 1/sin(4A)

Next, let's simplify the expression on the left side by finding a common denominator:

(sin(4A) + cos(4A))/(sin(2A) x sin(4A)) = cos(A)/sin(A) - 1/sin(4A)

[(cos(A) x sin(4A) - sin(A))/(sin(A)  x sin(4A))]  = [(cos(A) - sin(A))/(sin(A) x sin(4A))]

or, sin(4A) + cos(4A) = cos(A) - sin(A)

Using the double-angle identity sin(2A) = 2sin(A)cos(A):

2sin(A)cos(A) + cos(4A) = cos(A) - sin(A)

Next, double-angle identity cos(2A) = 1 - 2sin²(A):

2sin(A)cos(A) + cos(2A)cos(2A) = cos(A) - sin(A)

Using the identity cos(2A) = 1 - 2sin²(A) again:

2sin(A)cos(A) + (1 - 2sin²(A))(1 - 2sin²(A)) = cos(A) - sin(A)

Expanding and simplifying the equation:

2sin(A)cos(A) + 1 - 4sin²(A) + 4sin⁴(A) = cos(A) - sin(A)

4sin⁴(A) - 4sin²(A) + 2sin(A)cos(A) - sin(A) - cos(A) + 1 = 0

Now, let's factor the equation:

(2sin(A) - 1)(2sin(A) + 1)(2sin²(A) - 1) = 0

We know that sin(A) cannot be equal to 1 or -1, so the equation reduces to:

2sin²(A) - 1 = 0

This is equivalent to the identity sin²(A) + cos²(A) = 1, which is true for all angles A.

Therefore, the equation cosec(2A) + cot(4A) = cot(A) - cosec(4A) holds true.
