Using complementary angles, it is found that the solution to the trigonometric equation is of x = 20.

Complementary angles are two angles whose measures add to 90º.

If two angles a and b are complementary, we have that the sine of one is the cosine of other, that is:

[tex]\sin{a} = \cos{b}[/tex]

In this problem, the equation is:

[tex]\sin{(2x)} = \cos{(x + 30)}[/tex]

Hence, they are complementary, which means that:

[tex]2x + x + 30 = 90[/tex]

[tex]3x = 60[/tex]

[tex]x = \frac{60}{3}[/tex]

[tex]x = 20[/tex]

The solution to the trigonometric equation is of x = 20.

A series can be an arithmetic series or geometric series

The series is undefined

The given parameters about the geometric series are:

a1 = -2 --- the first term

r=-2 --- the common ratio

Sn=22 --- the sum of n terms

The sum of n terms of a geometric series is represented as:

[tex]S_n = \frac{a(r^n - 1)}{(r-1)}[/tex]

Substitute known values

[tex]22 = \frac{-2((-2)^n -1)}{(-2-1)}[/tex]

This gives

[tex]22 = \frac{-2((-2)^n -1)}{(-3)}[/tex]

Divide both sides by -2

[tex]-11 = \frac{((-2)^n -1)}{(-3)}[/tex]

Multiply both sides by -3

[tex]33 = (-2)^n -1[/tex]

Add 1 to both sides

[tex](-2)^n = 34[/tex]

Take the natural logarithm of both sides

[tex]n\ln(-2) = \ln(34)[/tex]

Solve for n

[tex]n= \frac{\ln(34)}{\ln(-2) }[/tex]

The above number is a complex number.

Hence, the series is undefined

i know the answer cuz i did this before.

The pattern is that for every minute four dots are added diagnally. To find how many doths there are at 100 minutes we will multiply 4 x 100 and then add one for the dot e started at. 4 x 100 = 400 + 1 = 401

At 100 minutes there will be 401 dots.

Answer:

You can use a sequence of two or more transformations to map a preimage to its image. You can map AABC onto AA"B"C" by a translation 3 units right followed by a 90° clockwise rotation about the origin.

A sequence of transformations to map a preimage to its image is reflection.

It is required to find the transformations to map a preimage to its image.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

Given:

Transformation maps the pre-image, DEFG, to the image, D'E'F'G'. The transformation is a reflection.

The line of reflection must go through the center point. Two lines of reflection go through the sides of the figure. Two lines of reflection go through the vertices of the figure. Thus, there are four possible lines that go through the center and are lines of reflections.

Therefore, a sequence of transformations to map a preimage to its image is reflection.

Answer:

just x = 1 is a root.

Step-by-step explanation:

p(-1) = 5(-1)³ - 2(-1)² + 3(-1) - 6 = -5 - 2 - 3 - 6 = -26

so x= -1 isn't root for p(x)

p(1) = 5(1)³ - 2(1)² + 3(1) - 6= 5 - 2 + 3 - 6= 0

so x = 1 is a root for p(x)

The mean of a dataset is the average of the dataset

The mean of all the sample data is 4.67 hours

The datasets are given as:

Week A: 6, 5, 5, 6, 4, 6, 8, 5, 2, 6

Week B: 0, 6, 6, 5, 4, 5, 6, 3, 4, 9

Week C: 4, 5, 6, 4, 3, 2, 2, 3, 12, 1

The mean of a dataset is:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

Week A

[tex]\bar x_A = \frac{6+ 5+ 5+ 6+ 4+ 6+ 8+ 5+ 2+ 6 }{10}[/tex]

[tex]\bar x_A =5.3[/tex]

Week B

[tex]\bar x_B = \frac{0+ 6+ 6+ 5+ 4+ 5+ 6+ 3+ 4+ 9}{10}[/tex]

[tex]\bar x_B = 4.8[/tex]

Week C:

[tex]\bar x_C = \frac{4+ 5+ 6+ 4+ 3+ 2+ 2+ 3+ 12+ 1}{10}[/tex]

[tex]\bar x_C = 4.2[/tex]

Calculate the mean for the three weeks

[tex]\bar x = \frac{5.3 + 4.8 + 4.2}{3}[/tex]

[tex]\bar x = 4.76[/tex]

Hence, the mean of all the sample data is 4.67 hours

Answer:

Option C

Step-by-step explanation:

Given the following question:

Using the process of elimination, we can find the answer:

It's not option A, because in order for a table to be a linear function the change of x, and the change of y have to be constant. In this case our change in y goes through -2, to -1. Which means option A is not a linear function.

It's not option A because again in order for a table to be a linear function the change of x and the change of y have to be constant. In this case our change of x is constant but our change in y isn't.

It's not option D because in order to have a linear function, you have to be able to rewrite the function into slope intercept (y = mx + b) in this case we only have one real number which is 12, while having our x, and y variable. Which means option D isn't a function.

Which leaves option C or "4x + 3y = 12" which is your answer, because it can be rewritten in slope intercept form.

Answer:

x = 14

Step-by-step explanation:

(4y - 10) + 3x = 180

in other hand: 4y - 10 = 9x + 12

so : (9x + 12) + 3x = 180

9x + 3x = 180 - 12

12x = 168

x = 168/12

x = 14

9) pi/3 = 180 /3 = 60⁰

the other angle = 90-60=30⁰

10) 2pi/9 = 360/9 = 40⁰

the other angle = 90+40=130⁰

11) arc length = 2pi * r * (θ/360)

= 2pi * 16 * (270/360)

= 75.4 km

12)arc length = 2pi * r * (θ/360)

3 * 180/4 = 135⁰

135/360 =0.375

2pi * 6 * 0.375 =14.13 in

13) arc length = 2pi * r * (θ/360)

= 9 *2pi *(255/360) =40.05 mi

14)arc length = 2pi * r * (θ/360)

=23.56 mi
