Answer:T = 2*Pi / (Pi / 3) = 6 seconds

Step-by-step explanation:

The time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)

Trigonometric functions are periodic. They repeat their values after some specific constant input interval (constant depends on the trigonometric function chosen).

For sine function, its period is 2π

Thus, we get:

[tex]y = \sin(x) = \sin(x+2\pi) = \sin(x + 2\pi n) ; n \in \mathbb Z[/tex] integer, and y is some constant at some constant value of x)

For this case, the pendulum's motion is modeled by:

[tex]P(t) = -10\sin\left(\dfrac{\pi}{3} t\right)[/tex]

Let it takes 'd' seconds to do one full cycle, then we get:

[tex]P(t) = P(t+d) = P(t+2d) = P(t + nd); n \in \mathbb Z - \mathbb Z^{-}[/tex] (n is non-negative integer).

Using the formula, we get:
[tex]-10\sin\left(\dfrac{\pi}{3} t\right) = -10\sin\left(\dfrac{\pi}{3} (t + nd)\right)\\\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t + \dfrac{\pi}{3}nd\right)[/tex]

But we know that:

[tex]\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t +2\pi n\right)[/tex]

Thus, we get:

[tex]2\pi n = \dfrac{\pi}{3}nd\\[/tex] (compared for non-negative values of n)

This gives:

[tex]d = \dfrac{2\pi n \times 3}{\pi n} = 6[/tex] (in seconds)

Thus, the time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)

Step-by-step explanation:

55 x 3.25 = 178.75

625-178.75 = 446.25

446.25 - 5.75 = 440.5

440.5-5.75 = 434.75

434.75-5.75 = 429

429-5.75 = 423.25

423.25-5.75 = 417.5

417.5-5.75 = 411.75

411.75-5.75 = 406

406-5.75 = 400.25

400.25-5.75 = 394.5

394.5-5.75 = 388.75

388.75-5.75 = 383

383-5.75 = 377.25

377.25-5.75 = 371.5

371.5-5.75 = 365.75

365.75-5.75 = 360

360-5.75 =354.25

354.25-5.75 = 348.5

348.5-5.75 = 342.75

342.75-5.75 = 337

337-5.75 = 331.25

331.25-5.75 = 325.5

325.5-5.75 = 319.75

319.75-5.75 = 314

314-5.75 = 308.25

308.25-5.75 = 302.5

302.5-5.75 = 296.75

296.75-5.75 = 291

291-5.75 = 285.25

285.25-5.75 = 279.5

279.5-5.75 = 273.75

273.75-5.75 = 268

268-5.75 = 262.25

262.25-11.5 = 250.75

250.75-11.5 = 239.25

239.25-11.5 = 227.75

227.75-11.5 = 216.25

Using the given percentage, we found that the total number of chocolate chip muffins sold is 80.

What is meant by percentage?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word per cent means. A % is a number without dimensions and without a standard measurement. The value of "whole" in this relationship between portion and whole is always set at 100.

Given,

 the number of chocolate  chip muffins sold = 36

The 36 muffins is the 45% of the total muffins sold.

Let the total number of muffins sold be x.

Then using the given percentage, we find the total muffins sold.

Percentage = (required number of muffins sold/ total number sold) *100

45% = 36/x * 100

0.45 = 36/x

x = 36/0.45 = 80

Therefore using the given percentage, we found that the total number of chocolate chip muffins sold is 80.

Answer:

18

Step-by-step explanation:

A left skewed data is one which it's tail is to the left of the distribution. This means the data is negatively skewed. One of the difference various characteristics of a left skewed data wh in could help find an answer to the question is that, for a left skewed distribution, the mean of the data is lower lesser than other measures of center and the mean falls to the left side of de of the peak. Hence, to create a data that is left skewed, we add the value from the options which will decrease the initial value of Mean.

From. The options ; adding 34 and 32 will increase the value the mean.

However, adding 18 will decrease the value value of the initial mean and hence, shift to the left of the peak.

Answer:

[tex]\displaystyle x=\left\{\frac{\pi}{2}, \frac{7\pi}{6}, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}[/tex]

Step-by-step explanation:

We are given the equation:

[tex](\sin(x)-\cos(x))^2=1+\cos(x)[/tex]

And we want to find all solutions for the equation within the interval [0, 2π).

First, we can expand. This yields:

[tex]\sin^2(x)-2\sin(x)\cos(x)+\cos^2(x)=1+\cos(x)[/tex]

From the Pythagorean Identity, we know that:

[tex]\sin^2(x)+\cos^2(x)=1[/tex]

Therefore:

[tex]-2\sin(x)\cos(x)+1=1+\cos(x)[/tex]

Simplify:

[tex]-2\sin(x)\cos(x)=\cos(x)[/tex]

Subtract cos(x) from both sides*:

[tex]-2\sin(x)\cos(x)-\cos(x)=0[/tex]

Factor:

[tex]\cos(x)\left(-2\sin(x)-1)=0[/tex]

Zero Product Property:

[tex]\cos(x)=0\text{ or } -2\sin(x)-1=0[/tex]

Solve for each case:

[tex]\displaystyle \cos(x)=0\text{ or } \sin(x)=-\frac{1}{2}[/tex]

Use the unit circle. So, our solutions are:

[tex]\displaystyle x=\left\{\frac{\pi}{2}, \frac{7\pi}{6}, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}[/tex]

*Note that we should not simply divide both sides by cos(x) to acquire -2sin(x) = 1. This is because we do not know what the value of x is, and so one or may values of x may result in cos(x) = 0, and we cannot divide by 0. Hence, we need to subtract and factor and utilize the Zero Product Property.

Answer:

[tex]x = 16[/tex]

Step-by-step explanation:

[tex] \frac{1}{2} (x + 8) - 16 = - 4[/tex]

[tex] \frac{1}{2} x + 4 - 16 = - 4[/tex]

[tex] \frac{1}{2} x + 4 = 12[/tex]

[tex] \frac{1}{2} x = 8[/tex]

[tex]x = 16[/tex]

Answer:

Step-by-step explanation:

[tex]\frac{1}{2}(x + 8 ) - 16 = - 4\\\\\frac{1}{2}*x + 8*\frac{1}{2} - 16 = -4\\\\\frac{1}{2}x + 4 - 16 = -4\\\\\frac{1}{2}x -12 = -4[/tex]

Add 12 to both sides

[tex]\frac{1}{2}x = -4 + 12\\\\\frac{1}{2}x = 8\\[/tex]

Multiply both sides by 2

[tex]x = 8*2\\\\x = 16[/tex]
