Answer:

sin(x + Pi)

= sin(x)cos(Pi) + cos(x)sin(Pi)

= sin(x) · –1 + cos(x) · 0

= –sin(x)

Step-by-step explanation:

edge 2020/2021

The simplification of the trigonometric sinusoidal function of sin(x + π) is given as negative of sin x.

It is a function that repeats itself in a particular time interval.

The expression is given as sin(x + π)

We know that the sine formula is given as

[tex]\sin (A+B) = \sin A \cos B + \cos A \sin B[/tex]

Then we have

A = x and B = π

Then the sin (x + π) will be

[tex]\sin (x+\pi) = \sin x \cos \pi + \cos x \sin \pi\\\\\sin (x+\pi) = \sin x \times (-1) + \cos x \times 0\\\\\sin (x + \pi ) = - \sin x[/tex]

Step-by-step explanation:

Cost price of the watch = $525

Discount percentage = 15%

So selling price = 525 - 15% of 525

= 15/100 x 525 = 262.5

Selling price = 525 - 262.5 = $262.5

Selling price = $262.5

Answer:

Explained below.

Step-by-step explanation:

The population model for Orlando, Florida from 2000 through 2007 is:

[tex]P = 1656.2\times e^{kt}[/tex]

It is provided that, in 2005, the population of Orlando was about 1,940,000.

(a)

Compute the value of k as follows:

For year 2005, the value of t is 5.

[tex]P = 1656.2\times e^{kt}[/tex]

[tex]1940000=1656.2\times e^{k\times 5}\\\\e^{k\times 5}=\frac{1940000}{1656.2}\\\\e^{k\times 5}=1171.35612\\\\5k=\ln(1171.35612)\\\\k=\frac{7.06592}{5}\\\\k=1.413184\\\\k\approx 1.41[/tex]

Since the value of k is positive, the population is increasing.

(b)

Compute the populations of Orlando in 2010 as follows:

[tex]P = 1656.2\times e^{kt}[/tex]

   [tex]=1656.2\times e^{1.41\times 10}\\\\=2201227729.68\\\\\approx 2,201,227,730[/tex]

Compute the populations of Orlando in 2015 as follows:

[tex]P = 1656.2\times e^{kt}[/tex]

   [tex]=1656.2\times e^{1.41\times 15}\\\\=2537704633019.96\\\\\approx 2,537,704,633,020[/tex]

Since the population increased exponentially from 2010 to 2015, yes the results are reasonable.

Answer:

Step-by-step explanation:

(3/7)/4=3/16

Answer:

b=4

Step-by-step explanation:

4b+5=1+5b (subtract 4b on both sides to get the b's together)

-4b         -4b

5=1+5b-4b (subtract 1 from both sides)

-1  -1

4=1b (divide by 1)

Answer:

The actual mass is either 453 or 447

Step-by-step explanation:

7 percent of 450

= (7/100) * 45

= 3.15

error = 3.15 g

hence actual mass

= 450 + 3.15

= 453.15

or

= 450 - 3.15

= 446.85

Have a good day:)

Answer:

$245.65

Step-by-step explanation:

1. Determine how much is being spent.

- You are paying for only 85% of the bike since it is discounted by 15%.

2. Multiply 0.85 and 289.

- If you are only paying for 85% of the bike, that is what needs to be found.

Answer:

450 yards in 3 minutes.

Step-by-step explanation:

30/4 = 7.5, which means he runs 7.5 ft per second.

7.5*60 = 450, which means that he runs 450 ft per minute.

450*3 = 1,350, which means that he can run 1,350 ft in 3 minutes.

1 yard = 3 ft

1,350/3 = 450, which means that he can run 450 yards in 3 minutes.

15×3=45. 3 faces so 45×3= 135

120+135=255

36+27=63

255+63=318

answer =318

Answer:

(x² + 7x + 6) ÷ (x² + 2x + 1)

This should be in the form of a fraction, I just don't know how to format it that way on here.

Step-by-step explanation:

Since your denominators are equal on both fractions, you just need to subtract your numerators.

3x² + 9x + 12 - (2x² + 2x + 6)

When there is a - in front of an expression in parenthesis, you should change the sign of each term in the expression of the numerator being subtracted.

So this:

2x² + 2x + 6

Will become this:

2x² - 2x - 6

This is how it will look:

3x² + 9x + 12 - 2x² - 2x - 6

Now all you have to do is collect the like terms.

3x² and -2x² are like terms so you will add them together: 3x² + (-2x²) = 3x² - 2x² = x²

This is how your numerator should look so far:

x² + 9x + 12 - 2x - 6

Now we move on to the next like terms.

9x and -2x are like terms so we add them together: 9x + (-2x) = 9x - 2x = 7x

This is how your numerator should look so far:

x² + 7x + 12 - 6

Now we move on to the last set of like terms.

12 and -6 are like terms so we add them together: 12 + (-6) = 12 - 6 = 6

This is how your numerator should be now:

x² + 7x + 6

Now all you have to do is put your numerator on top of your denominator which is the same as in the start of your equation (x² + 2x + 1).

You are done! I hope this was clear and you understand :)
