[tex]\angle 12 \cong \angle 8\\\angle 4 \cong \angle 8[/tex]

Step-by-step explanation:

When two parallels lines are crossed by a transversal, certain pair of angles are called corresponding angles, specifically, those that are placed in the same side of the transversal, on inside the parallels and the other outside the parallels. The image attached shows an example of corresponding angles.

So, we observe in the given image that all corresponding angles with angle 8 are

Answer:

1 / x^8

Step-by-step explanation:

We know that a^b / a^c = a^ (b-c)

x^7 / x^ 15 = x^ (7-15) = x^-8

We also that that a^-b = 1/ a^b

x^-8 = 1 / x^8

Answer:

1/(x^8)

Step-by-step explanation:

Simplify by the following steps. To make it easier, I will expand them:

First, expand each of the powers out:

[tex]\frac{x^7}{x^{15} } = \frac{x* x * x * x * x * x * x}{x * x * x * x * x * x * x * x * x * x * x * x * x * x * x}[/tex]

When dividing with the same variables with different powers, you are effectively subtracting the powers. Your answer will look like:

[tex]\frac{x^7}{x^(15)} = x^{7 - 15} = x^{-8}[/tex]

Next, simplify. Note that if there is a negative sign in the power, you must change the sign into a positive by flipping the fraction.

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

1/(x^8) is your answer.

[tex]Z=2.99999999999995[/tex]

Step-by-step explanation:

We can write the proportionality equation as:

[tex]Z=k\frac{X}{Y}[/tex]

Note: Directly proportional goes top and top, multiplied. And inversely proportional goes top bottom, divided. Also, k is the proportionality constant.

When X is 3, Y is 19, Z is 0.94736842105263. Plugging these, we figure out k:

[tex]Z=\frac{kX}{Y}\\0.94736842105263=\frac{k(3)}{19}\\k=\frac{0.94736842105263*19}{3}\\k=5.99999999999999[/tex]

Answer:

Function.

Step-by-step explanation:

A relation is a function every x that in your domain only gets assigned to exactly one number in your range.

Basically if you have a set of points and you see that the same x is being used more than once, then it isn't a function (unless for some reason they repeated the same point).

So the x's I see in the order that your points are is 3,1,-1,-2.  All of these x's are different so it is a function.

Answer: Yes, it is a function.

Step-by-step explanation:

Usually we denote the input value as 'x' and the output value as 'y'.

The given relation: {(3, −5), (1, 2), (−1, −4), (−2, 2)}

Here , each input value corresponds an unique output value.

Therefore , the given relation is a function.

Answer:

16

Step-by-step explanation:

If you have a 12-inch board and you are making 3/4 inch long sections, and you want to know many times you can do that here.

You just need to take 12 and divide it by the 3/4, to see how many sections you can have.

[tex]12 \div \frac{3}{4}[/tex]

Change division to multiplication by taking the reciprocal (the flipping) of the second number:

[tex]12 \cdot \frac{4}{3}[/tex]

Write 12 as a fraction:

[tex]\frac{12}{1}\cdot \frac{4}{3}[/tex]

To multiply fractions, multiply straight across on top and straight across on bottom:

[tex]\frac{(12)(4)}{(1)(3)}[/tex]

[tex]\frac{48}{3}[/tex]

16

Final answer:

By dividing the 12-inch board length by the section length of 3/4 inches, we find that 16 sections can be made.

Explanation:

The question asks how many sections of 3/4 inches can be made from a 12-inch board. To find this, divide the total length of the board by the length of each section. Calculate by dividing 12 inches by 3/4 inches (which is the same as 12 divided by 0.75 in decimal form).

Therefore, you can cut 16 sections that are 3/4 inches long each from a 12-inch board.

Answer:

The new function is (x + 7)² - 47 ⇒ the 3rd answer

Step-by-step explanation:

* Lets put the function f(x) in the vertex form at first and then make

 the translation

∵ The general form of the quadratic function is

  f(x) = ax² + bx + c

∵ The x-coordinate of the vertex of the function is -b/2a

∵ The y-coordinate of the vertex of the function is f(-b/2a)

- Lets find a , b from the function two find the vertex point

∵ f(x) = x² + 22x + 58

∴ a = 1 , b = 22 , c = 58

∵ x-coordinate of the vertex = -b/2a

∴ x-coordinate of the vertex = -22/2(1) = -11

∵ y-coordinate of the vertex = f(-11)

∴ f(-11) = (-11)² + 22(-11) + 58 = 121 - 242 + 58 = -63

∴ The vertex point is (-11 , -63)

- The vertex form of the quadratic function is f(x) = (x - h)² + k , where

  (h , k) are the coordinates of the vertex point

∵ The vertex point is (-11 , -63)

∴ h = -11 , k = -63

∴ f(x) = (x - -11)² + -63

∴ f(x) = (x + 11)² - 63

* lets revise the rules of the translation

- If the function f(x) translated horizontally to the right  

 by m units, then the new function g(x) = f(x - m)

- If the function f(x) translated horizontally to the left  

 by m units, then the new function g(x) = f(x + m)

- If the function f(x) translated vertically up  

 by n units, then the new function g(x) = f(x) + n

- If the function f(x) translated vertically down  

 by n units, then the new function g(x) = f(x) – n

∵ f(x) will translate 4 units to the right

∴ m = 4

∵ f(x) ⇒ f(x - m)

∴ (x + 11)²  ⇒ (x + 11 - 4)² = (x + 7)²

∵f(x) will translate 16 units up

∴ -63 will add by 16

∴ n = 16

∴ f(x) ⇒ f(x) + n

∵ -63 + 16 = -47

∴ The new function is (x + 7)² - 47

Step-by-step explanation:

I'm going to look at y=3x+2 first.

This is a linear equation in slope-intercept form.

Slope-intercept form is y=mx+b.

It is called slope-intercept form because it tells us m, the slope, and b ,the y-intercept.

So I'm going to draw a point at 2 on the y-axis (because 2 is our y-intercept).

From that point, I'm going to count up 3 and right once because our slope is 3 (which is 3/1; slope=rise/run).  So my next point will be at (1,5).

Now let's go back to y>3x+2.

Since it says y>, then we shade above.

If it had said y<, then we shade below.

There is only one more thing to consider, and that is the lack of or there of of the equal sign.

If the equal sign part is there, your line will be solid.

If the equal sign is not there, your line will be dashed or broken.

(f* g)(x) = x(x - 1) 3x

            = (x^2 -x) * 3x

            = 3x^3 -3x^2

            =3x^2(x-1)

Let x = 6

Step-by-step explanation:

(f*g)(6)=f(6)*g(6).

So f(6)=30.

g(6) means to replace x in 3x with 6:

So g(6)=18.

(f*g)(6)=f(6)*g(6)=30*18=540.

Step-by-step explanation:

We are going to use the identity

[tex]\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)[/tex]

because this identities right hand side matches your expression where

[tex]a=\frac{\pi}{7}[/tex] and [tex]b=x[/tex].

So we have that [tex]\sin(\frac{\pi}{7})\cos(x)+\cos(\frac{\pi}{7})\sin(x)[/tex] is equal to [tex]\sin(\frac{\pi}{7}+x)[/tex].

The given expression is written as sin(π/7 + x). Using sine of compound angle identity it is obtained.

A compound angle is the sum of two or more angles. Consider A and B are two angles. Where their compound angle becomes A + B. So, the sine and cosine of this compound angle are

1) sin (A + B) = sin A cos B + cos A sin B

2) sin (A - B) = sin A cos B - cos A sin B

3) cos (A + B) = cos A cos B - sin A sin B

4) cos (A - B) = cos A cos B + sin A sin B

The given expression is sin(π/7) cos(x) + cos(π/7) sin(x)

This is in the form of sin A cos B + cos A sin B

where A = π/7 and B = x

So, using the above identity we can write,

sin(π/7) cos(x) + cos(π/7) sin(x) = sin(π/7 + x)

Thus, the given expression is expressed in the angle of sine. I.e., sin(π/7 + x).
