The equivalent expression to 3218y = 8√3y is 4√(15) / 15y when y is not equal to zero. Option C is the correct answer.

To find an equivalent expression to 3218y = 8√3y when y is not equal to zero, we can start by dividing both sides of the equation by 8y, giving us:

3218y / 8y = 8√3y / 8y

Simplifying the right-hand side, we get:

3218 / 8 = √3

Squaring both sides, we get:

(3218 / 8)² = 3

Simplifying the left-hand side, we get:

130071.25 = 3

Dividing both sides by 3, we get:

y = 4√(15) / 15

Therefore, the expression that is equivalent to 3218y = 8√3y when y is not equal to zero is an option (C) 4√(15) / 15y. Option (D) 46y is not equivalent to the original expression because it does not involve the square root of 3. Option (A) 12V / 2y² and option (B) 46 are also not equivalent to the original expression because they involve different values and operations than those in the original expression.

Step-by-step explanation:

It will take the pendulum approximately 0.20 seconds to reach its resting position.

We have,

The resting position of the pendulum is when d(t) = 0.

So we need to solve the equation:

5.5cos(8t) = 0

We know that cos(0) = 1 and that cos(π) = -1, and that the cosine function has a period of 2π.

Therefore, the first time the pendulum will reach its resting position is at

t = 0, and then it will reach its resting position again at t = π/8.

However, we are interested in the time it takes for the pendulum to go from its starting position to its resting position, which is half of its period.

So the time it takes for the pendulum to reach its resting position is:

t = π/8 / 2

t = π/16

Using a calculator, we can approximate this value to the nearest hundredth:

t = 0.20 seconds

Therefore,

It will take the pendulum approximately 0.20 seconds to reach its resting position.

Bruce can finish the job alone in 5 hours, Bryce can finish the job alone in 8 hours, and Marty can finish the job alone in 10 hours.

Let's assume the job takes x hours for Bruce to complete alone, y hours for Bryce to complete alone, and z hours for Marty to complete alone.

From the first piece of information, we can create the following equation based on the work completed in 1 hour and 20 minutes (4/3 hours):

1/x + 1/y = 3/4

From the second piece of information, we can create the following equation based on the work completed in 1 hour and 36 minutes (8/5 hours):

From the third piece of information, we can create the following equation based on the work completed in 2 hours and 40 minutes (8/3 hours):

The solution for the equation ax + by ≡ c (mod 3) does not exist. Hence, it  has no solution.

We need to prove that the equation ax + by ≡ c (mod 3) has no solution.

Since 3 | a and 3 | b, we know that a ≡ 0 (mod 3) and b ≡ 0 (mod 3).

Now let's look at the left side of the equation ax + by. Since a and b are both divisible by 3, their product with any integers x and y will also be divisible by 3.

Therefore, ax + by will always be divisible by 3 and can be written as ax + by ≡ 0 (mod 3).

However, we know that c ≡ 2 (mod 3), which means that c is not divisible by 3. Therefore, we can conclude that ax + by can never be congruent to c (mod 3), as their remainders when divided by 3 are different.

In other words, the equation ax + by ≡ c (mod 3) has no solution.

(Z/60Z)* contains 128 elements.

To find the multiplicative inverse of 41 in Z/60Z, we need to find an integer x such that 41x ≡ 1 (mod 60). Using the Euclidean algorithm:

60 = 1 × 41 + 19

41 = 2 × 19 + 3

19 = 6 × 3 + 1

Working backwards, we have:

1 = 19 - 6 × 3

= 19 - 6(41 - 2 × 19)

= 13 × 19 - 6 × 41

Therefore, 41 has a multiplicative inverse of 13 in Z/60Z. Similarly, we can find that 43 has a multiplicative inverse of 7 in Z/60Z.

The elements of (Z/60Z)* are the integers in the range [1, 60] that are relatively prime to 60. To count them, we can use the formula for Euler's totient function:

φ(60) = φ(2^2) × φ(3) × φ(5) = 16 × 2 × 4 = 128

The null hypothesis and conclude that there is sufficient evidence to support the claim that the percentage of people with genetic markers is less than 1%.

To test whether the percentage of people with genetic markers is less than 1%, we can use a one-tailed hypothesis test with the following null and alternative hypotheses:

H0: p >= 0.01

Ha: p < 0.01

where p is the true proportion of people with the genetic markers.

Using the sample proportion, p-hat = 3/500 = 0.006, and the sample size, n = 500, we can calculate the test statistic z:

z = (p-hat - p) / sqrt(p * (1 - p) / n)

= (0.006 - 0.01) / sqrt(0.01 * 0.99 / 500)

= -1.434

At 75% confidence, the critical value for a one-tailed test is -1.15 (using a standard normal distribution table or calculator).

For part (c)(ii), we need to explain why the theorem in (b) does not apply to g(z).

The theorem in (b) states that for any polynomial with real coefficients, if zo € C is a root, then zo is also a root. However, g(z) = z^2 - 2z does not have real coefficients, as the coefficient of the z term is -2, which is not a real number.

Therefore, we cannot apply the theorem in (b) to g(z) since it does not satisfy the condition of having real coefficients. However, we can still find the roots of g(z) and show that they satisfy the conclusion of the theorem in (b) if we consider g(z) as a polynomial with complex coefficients.

To find the roots of g(z), we set g(z) equal to zero and solve for z:

z^2 - 2z = 0

z(z - 2) = 0

So the roots of g(z) are z = 0 and z = 2.

If we consider g(z) as a polynomial with complex coefficients, then we can apply the theorem in (b) and conclude that if z = 0 or z = 2 is a root of g(z), then it is also a root of g(z) with real coefficients. However, we cannot apply the theorem in (b) to g(z) directly since it does not have real coefficients.

Hi! To find the orthogonal trajectories of the given curve s = 3a sin θ, we first need to determine its differential equation by eliminating the arbitrary constant, a. The orthogonal trajectories should have slopes that are the negative reciprocal of the original curve's slopes.

1. Differentiate s with respect to θ:
ds/dθ = 3a cos θ

2. Solve for a:
a = (ds/dθ) / (3 cos θ)

3. Substitute the expression for a back into the original equation:
s = 3((ds/dθ) / (3 cos θ)) sin θ

4. Simplify:
s = (ds/dθ) tan θ

5. Find the orthogonal trajectories by taking the negative reciprocal of the original slope:
-1 = -ds/dθ / s

6. Rearrange to find the differential equation for the orthogonal trajectories:
ds/dθ = s

7. Integrate with respect to θ to find the orthogonal trajectories:
s(θ) = c * e^θ, where c is an arbitrary constant.

So, the orthogonal trajectories of the given curve s = 3a sin θ are s(θ) = c * e^θ.
