It is true that the value of tanΘ can be found by dividing sinΘ by cosΘ. This can be verified using the identity:tanΘ = sinΘ/cosΘ. We can verify that tanΘ = sinΘ/cosΘ using the following steps:

1. Assume Θ is an angle and sinΘ and cosΘ are the respective values of the sine and cosine functions at that angle.

2. Then we can use the definition of tanΘ:tanΘ = sinΘ/cosΘ

3. Thus, the above identity is verified that tanΘ = sinΘ/cosΘ. The proof is complete. Therefore, we have verified that tanΘ = sinΘ/cosΘ.

Answer:

The sequence is:

5, 14, 23, 32

Step-by-step explanation:

We know that an Arithmetic sequence with a₁ and the commo difference 'd' has the nth term such as:

aₙ = a₁ + (n-1)d

Given the arithmetic sequence

5, _____, ______, 32

here:

a₁ = 5

n = 4

aₙ

so substituting a₁ = 5, n = 4 and aₙ = 32 in the nth term

aₙ = a₁ + (n-1)d

32 = 5 + (4-1)d

32 = 5 + 3d

3d = 32-5

3d = 27

divide both sides by 3

3d/3 = 27/3

d = 9

Therefore, the common difference: d = 9

Determining the 2nd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 2, a₁ = 5, d = 9

a₂ = 5 + (2-1)9

a₂ = 5 + 1(9)

a₂ = 5 + 9

a₂ = 14

Determining the 3rd term:

Using the formula

aₙ = a₁ + (n-1)d

substitute n = 3, a₁ = 5, d = 9

a₃ = 5 + (3-1)9

a₃ = 5 + 2(9)

a₃ = 5 + 18

a₃ = 23

Thus, the sequence becomes:

5, 14, 23, 32

The function g(x) is given by:

g(x) = (68/π) (1/x²) sin(π/4x²).

We have,

To find the integral of the function g(x) = ∫[0, x] (-34t cos(π/4t²)) dt, we can evaluate the integral using the fundamental theorem of calculus.

The antiderivative of -34t cos(π/4t²) with respect to t can be found by applying the chain rule in reverse.

We set u = π/4t² and find du/dt = -π/2t³.

Rearranging, we have dt = -(2/π) x (1/t³) du.

Substituting back into the integral:

g(x) = ∫[0, x] (-34tcos(π/4t²)) dt

= ∫[0, x] (-34tcos(u)) x -(2/π) x (1/t³) x du

= (68/π) x ∫[0, x] (cos(u)/t²) du.

Now, we can evaluate this integral.

The integral of (cos(u)/t²) with respect to u can be found using basic integration rules:

∫ (cos(u)/t²) du = (1/t²) x ∫ cos(u) du

= (1/t²) x sin(u) + C,

where C is the constant of integration.

Substituting back into the expression for g(x):

g(x) = (68/π)  [(1/t²) sin(u)] evaluated from 0 to x

= (68/π)  [(1/x²)  sin(π/4x²) - (1/0²)  sin(π/4 x 0²)]

= (68/π)  [(1/x²)  sin(π/4x²) - 0]

= (68/π) (1/x²) sin(π/4x²).

Therefore,

The function g(x) is given by:

g(x) = (68/π) (1/x²) sin(π/4x²).

A'(-16, 32)

T'(48, 24)

Step-by-step explanation:

For this question, simple multiply all the points by 8.

To determine whether the given series converges or diverges, we need to analyze the behavior of the terms as n approaches infinity.

The series [infinity] n − 1 n 5n n = 1 can be written as Σ (n - 1) / (\(n^5\)) from n = 1 to infinity.

To analyze the convergence or divergence of this series, we can use the Limit Comparison Test. Let's consider the series Σ (n - 1) / (\(n^5\)) and compare it to the series Σ 1 / (\(n^4\)).

By taking the limit as n approaches infinity of the ratio of the terms, we have:

lim (n → ∞) ((n - 1) / (\(n^5\))) / (1 / (\(n^4\)))

= lim (n → ∞) (n - 1) / n

= 1.

Since the limit is a finite nonzero value, the series Σ (n - 1) / (\(n^5\)) and Σ 1 / (\(n^4\)) have the same convergence behavior.

Now, we know that the series Σ 1 / (\(n^4\)) is a p-series with p = 4, and it converges because p > 1.

Therefore, by the Limit Comparison Test, we can conclude that the series [infinity] n − 1 n 5n n = 1 converges.

In conclusion, the given series converges.

Answer:

0 Joules (No work)

Step-by-step explanation:

The amount of work done on an object is equal to the force applied to the object times the distance over which the force is applied. In this case, the force applied to the car is 100 newtons, but the car does not move, so the distance over which the force is applied is 0 meters.

Therefore, the amount of work done on the car is 100 newtons * 0 meters = 0 joules. This means that no energy has been transferred to or from the car as a result of the force applied to it.

y should be raised to zero for it's value to be one.

To investigate the claim made by the pharmaceutical company that the mean cost of a 30-day supply of a certain heart medication is more than $51, we can establish the following null and alternative hypotheses:

Null Hypothesis (H0): The mean cost of a 30-day supply of the heart medication is not more than $51.

Alternative Hypothesis (H1): The mean cost of a 30-day supply of the heart medication is greater than $51.

Symbolically, the hypotheses can be represented as follows:

H0: μ ≤ $51

H1: μ > $51

In words, the null hypothesis states that the true population mean cost is less than or equal to $51. On the other hand, the alternative hypothesis suggests that the true population mean cost is greater than $51. By conducting appropriate statistical tests and analyzing the data, we can gather evidence to either support or reject the null hypothesis in favor of the alternative hypothesis.

The coordinate of point P is -8.

We are given that the endpoints of AB are -16 and -4.

This means that A is at -16 and B is at -4

Therefore, the total length of the line AB will be-

-16 - (-4) = -12 units

But since length cannot be negative, we take only the absolute value, the length of AB comes out to be 12 units.

Now, point P divides AB in the ratio 2:1

The length of these two parts will be

12 × 2/3 and 12 x 1/3

= 8 units and 4 units

This means that AP = 8 units and PB = 4 units

Hence the coordinate of P will be (-16 + 8) or (-4 - 4)

Thus, the coordinate of point P is -8.

The correct answer is D: Max (Peak Memory BW x Arithmetic Intensity, Peak Floating-Point Performance).

1a. C: 101 to calculate the speedup, we need to consider the computing load distribution among the processors. In this case, 10 processors carry 20% of the load, which means each of these processors handles 2% of the load. The remaining 90 processors share the rest of the load evenly, so each processor among these 90 handles (100% - 20%) / 90 = 0.8889% of the load.

The speedup can be calculated using Amdahl's Law, which states that the speedup is limited by the portion of the program that cannot be parallelized. In this case, the matrix subtraction is fully parallelizable, so the only portion that cannot be parallelized is the sum of the scalar variables.

The speedup formula is given by: Speedup = 1 / [(1 - p) + (p / n)], where p is the portion that can be parallelized and n is the number of processors.

In this case, p = 0.02 (for the 10 processors) and n = 100. Substituting these values into the formula, we get: Speedup = 1 / [(1 - 0.02) + (0.02 / 100)] = 1 / 0.99 = 1.0101.

Therefore, the correct answer is C: 101.
