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]

Now we put X = 13 and Y = 26 and k = 5.99999999999999, to find Z:

[tex]Z=\frac{kX}{Y}\\Z=\frac{(5.99999999999999)(13)}{26}\\Z=2.99999999999995[/tex]

Answer:

Begin with a line segment on the paper and fold the paper so that the segment's endpoints lie on top of each other.

The method used in paper folding to form the midpoint of a line segment is called bisecting a line segment. This involves drawing the line segment, folding the paper so the endpoints of the line segment meet, and marking the point of intersection which forms the midpoint.

The method that can be used in paper folding to form the midpoint of a line segment is called bisecting a line segment. Here's how you can do it:

That point of intersection is the midpoint of the line segment. You've now bisected the line segment into two equal halves using paper folding.

Since m = 4.5 and b = 21 the desired formula is:

T=4.5x+21

Answer:

In picture.

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.

Step-by-step explanation:

Ration expressions cause excluded values wherever the denominator equals zero.

So, for any expression like

[tex]h(x)=\dfrac{f(x)}{g(x)}[/tex]

-5 is an excluded value if [tex]g(-5)=0[/tex]

For example, the simplest one would be

[tex]h(x) = \dfrac{1}{x+5}[/tex]

In fact, if you try to evaluate this function at -5, you'd have

[tex]h(-5)=\dfrac{1}{5+5}=\dfrac{1}{0}[/tex]

which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.

[tex]\frac{(x--3)^2}{49} -\frac{(y-6)^2}{32}=1[/tex]

Step-by-step explanation:

The standard equation of a horizontal hyperbola with center (h,k) is

[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex]

The given hyperbola has vertices at (–10, 6) and (4, 6).

The length of its major axis is [tex]2a=|4--10|[/tex].

[tex]\implies 2a=|14|[/tex]

[tex]\implies 2a=14[/tex]

[tex]\implies a=7[/tex]

The center is the midpoint of the vertices (–10, 6) and (4, 6).

The center is [tex](\frac{-10+4}{2},\frac{6+6}{2}=(-3,6)[/tex]

We need to use the relation [tex]a^2+b^2=c^2[/tex] to find [tex]b^2[/tex].

The c-value is the distance from the center (-3,6) to one of the foci (6,6)

[tex]c=|6--3|=9[/tex]

[tex]\implies 7^2+b^2=9^2[/tex]

[tex]\implies b^2=9^2-7^2[/tex]

[tex]\implies b^2=81-49[/tex]

[tex]\implies b^2=32[/tex]

We substitute these values into the standard equation of the hyperbola to obtain:

[tex]\frac{(x--3)^2}{7^2} - \frac{(y-6)^2}{32}=1[/tex]

[tex]\frac{(x+3)^2}{49} -\frac{(y-6)^2}{32}=1[/tex]

Answer:

x = - 5, x = - 1

Step-by-step explanation:

To find the x- intercepts let f(x) = 0, that is

x² + 6x + 5 = 0 ← in standard form

Consider the factors of the constant term (+ 5) which sum to give the coefficient of the x- term ( + 6)

The factors are + 5 and + 1, since

5 × 1 = 5 and 5 + 1 = + 6, hence

(x + 5)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5 ⇒ (- 5, 0 )

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

(x + 7)^2 - 47

Answer:

1001 ways

Step-by-step explanation:

Total number of people who applied for the job = 8 + 6 = 14

Number of people to be chosen = 4

This is a combination problem because the order of selection does not matter. A group selection involves the combinations. So here we have to find the combinations of 14 people taken 4 at a time. The formula for the combination is:

[tex]^{n}C_{r} = \frac{n!}{r!(n-r)!}[/tex]

Here, n is the total number of objects which is 14 in this case.

r is the number of objects to be chosen which is 4 in this case.

Using these values, we get:

[tex]^{14}C_{4}=\frac{14!}{4!(14-4)!}\\\\ = \frac{14!}{4! \times 10!}\\\\ =1001[/tex]

Thus, there are 1001 ways to select 4 applicants from 8 men and 6 women for the second interview.

Option B is the correct answer.

We have,

To find the greatest common factor (GCF) of the polynomial

30x³ - 20x, we need to determine the largest expression that can be factored out from both terms.

Let's look at the coefficients first.

The coefficients of the terms are 30 and -20.

Both numbers are divisible by 10, so we can factor out 10.

Now let's consider the variable, x. In the first term, we have x³, and in the second term, we have x.

The lowest power of x that appears in both terms is x, so we can factor out x.

Putting it together, we can factor out the GCF of 10x:

GCF(30x³ - 20x) = 10x

Therefore,

The greatest common factor of the polynomial 30x³ - 20x is 10x.

The equation of the line passing through points (-3,2) and (2,15) is calculated using the point-slope formula after calculating the slope. The derived equation is y = 2.6x + 7.8.

The question is asking to find the equation of the line that passes through two given points: (-3,2) and (2,15). To tackle this, firstly we need to calculate the slope (m) of the line, which is given by the formula: (y2 - y1) / (x2 - x1). Secondly, we apply the point-slope formula, y - y1 = m(x - x1), where (x1, y1) can be either point.

Now, calculating the slope using the given points, we find (15-2) / (2- (-3)) equals to 13/5 or 2.6. Next, we use the point-slope formula to write the equation. If using point (-3,2) we find y - 2 = 2.6 (x - (-3)). Thus, the equation for the line that passes through (-3,2) and (2,15) is y = 2.6x + 7.8 after simplifying the equation.

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.
