The correct answer is option B.

"A function [tex]f(x)[/tex] is an odd function when [tex]f(-x)=-f(x)[/tex] ."

For given question,

Consider points A and B on the coordinate plane as shown in following image.

Let, line segment OA makes an angle of [tex]\theta[/tex] with x-axis and ∠COB = [tex]-\theta[/tex]

So, the coordinates of points on unit circle with radius 'r' would be, A[tex](cos \theta, sin\theta)[/tex] and B[tex](cos(-\theta),sin(-\theta) )[/tex]

Let, AC = y, BC = -y and OC = m

Now, consider sine function

[tex]sin\theta=\frac{AC}{OA}\\[/tex]

⇒[tex]sin\theta=\frac{y}{r}[/tex]                        ........................(1)

And, [tex]sin(-\theta)=\frac{BC}{OB}[/tex]

⇒ [tex]sin(-\theta)=\frac{-y}{r}[/tex]

⇒ [tex]sin(-\theta)=-(\frac{y}{r})[/tex]             .......................(2)

⇒ [tex]sin(-\theta)=-sin\theta[/tex]             ......................(From (1) and (2))

Now, consider cosine function

[tex]cos\theta=\frac{OC}{OA}[/tex]

⇒ [tex]cos\theta=\frac{m}{r}[/tex]                           ...........................(3)

And, [tex]cos(-\theta)=\frac{OC}{OB}[/tex]

⇒ [tex]cos(-\theta)=\frac{m}{r}[/tex]                      ...........................(4)

⇒ [tex]cos(-\theta)=cos\theta[/tex]                   ...........................(From (3), (4))

Hence, sine function is odd because it is represented by the y-coordinate of the points on the unit circle, and therefore sin(-x) = - sin(x).

Therefore, the correct answer is option B.

I hope this helps,good luck with everything.

Answer:

x = 5

Step-by-step explanation:

Use the inverse variation equation, y = k/x

Plug in 7 as x and 15 as y, then solve for k:

y = k/x

15 = k/7

105 = k

So, the equation is y = 105/x

Find x when y = 21 by plugging in 21 as y:

y = 105/x

21 = 105/x

21x = 105

x = 5

So, when y = 21, x = 5

A) The range for the month of October is 6.

C) 35 summarizes the data with a single number.

E) 16 describes how the values vary with a single number.

Step-by-step explanation:

Week 1 | 40 Week 1 | 32

Week 2 | 34 Week 2 | 30

Week 3 | 36 Week 3 | 40

Week 4 | 40 Week 4 | 24

The ordered data can be written out as follows :

October :

2C – 3B = 2(1+5n-6n²)-3(n+4n²)

= 2+10n-12n²-3n-12n²

= 2 +7n -24n²

The expression (2C-3B) equals to (-24x²+7x+2)

Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given are two expression, C = 1+5n-6n² and B = n+4n²

2C = 2+10n-12n²

3B = 3n+12n²

2C-3B = 2+10n-12n² - 3n-12n²

= -24n²+7n+2

Hence, The expression (2C-3B) equals to (-24x²+7x+2)

Answer:

296 ft²

Step-by-step explanation:   5 18 7 20

There are a few ways to calculate the area of the tihis composit figure.

The one way is to calculate the entire area of the big rectangle with the voided area and substract the smaller voided rectangle

Big rectangle with voided area  

26 × 16   = 26 × 10 + 26 × 6 =  260 + 156 =  416

Small Void Rectangle = 6 × (26 - 2 - 4)

                                    = 6 × 20

                                    = 120

Total area = Big rectangle with voided area - Small Void Rectangle

                 =   416 - 120

                 =  296 ft²

another way is to add up three areas

large filled rectangle +  smaller filled rectangle +  smallest filled rectangle

        10 × 26  +  4 × 6 + 2 × 6

           260 + 24 + 12

                296 ft²

"The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9" is correct edg 2021

The correct statement is "The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9".

In rough terminologies, the limit from one side is when we only use one side of the function with respect to the considered point of interest (in input) to predict the value of the function at that point.

For a limit of a function f(x) to exist at a point a,

[tex]\lim_{x \to a^-} f(x) = \lim_{x \to a^+} f(x)[/tex]

That is, it has to approach (a) from both sides toward the same value, thus it cannot be oscillating.

From the table, looking at the value of slightly less than 9,

[tex]\lim_{x \to 9^-} f(x)= 4.73[/tex]

Looking at the value of slightly more than 9,

[tex]\lim_{x \to 9^+} f(x) = -4.73[/tex]

Since the lateral limits are different, the limit does not exist.

The correct statement is "The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9".

Answer:

1/12

Step-by-step explanation:

Given the following :

Actual height of pyramid = 24 ft

Dimension of scaled model :

Height = 2ft ; width = 1ft

a scale factor is a number used to reproduce a reduced dimension of a model by multiplying the actual dimeznsion or size of the model or object.

Since the height is of the scaled model is less than the actual height of the pyramid ; then it could be said that the scale factor is a fraction, because reduction has occurred.

(Height of scaled model / height of actual pyramid)

(2ft / 24ft) = 1/12

Step-by-step explanation:

The surface area of the right cone is,

⇒ SA = 45π units²

The multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that;

Radius of cone (r) = 3 units

Slant height of cone (l) = 12 units

Now, We know that;

The formula that is used to calculate the surface area of a cone is;

⇒ SA = πrl + πr²

Hence, We can substitute all the values we get;

⇒ SA = πrl + πr²

⇒ SA = π × 3 × 12 + π × (3)²

⇒ SA = 36π + 9π

⇒ SA = 45π units²

Thus, The surface area of the right cone is,

⇒ SA = 45π units²
