Given (2, 6), the k-value is 2 · 6 = 12.

Which (x, y) coordinates have a product of 12?

A) (1, 3) --> 1 · 3 = 3

B) (1, 4)  --> 1 · 4 = 4

C) (3, 3) --> 3 · 3 = 9

D) (3, 4) --> 3 · 4 = 12      THIS WORKS!

In order for the equation to have infinite solutions, the left side must equal the right side.  Solve for "c"

8x - 2x(c + 1) = x

     -2x(c + 1) = -7x               subtracted 8x from both sides

           c + 1 = (-7x)/(-2x)      divided both sides by -2x

           c + 1 = 7/2                simplified

           c      = 5/2                subtracted 1 from both sides

The original negative number in the problem is found by setting up the equation 6x = x - 20 and solving for x, which results in the original number being -4.

If a certain negative number is multiplied by six, the result is the same as 20 less than the original number. To solve for the original number, we can set up an equation based on the given condition. Let's assume the original number is x.

According to the problem, 6 times x equals x subtracted by 20:

6x = x - 20

To solve for x, we'll first move all terms involving x to one side of the equation by subtracting x from both sides:

6x - x = -20

This simplifies to:

5x = -20

Now, divide both sides by 5 to isolate x:

x = -20/5

x = -4

Therefore, the value of the original number is -4.

Answer:

< 2.11, 4.53 >, < -3.03, -1.75 >, <2.93 cos 108.26, 2.93 sin 108.26 >

Step-by-step explanation:

First, let's decompose Bruce's velocity along the x- and y- direction. Bruce is moving 5 m/s at 25 degrees east of north, so its angle with respect to the positive x-direction is actually 90 - 25 = 65 degrees. So its components are

[tex]b_x = (5 m/s) cos 65^{\circ} =2.11 m/s\\b_y = (5 m/s) sin 65^{\circ} =4.53 m/s[/tex]

So, Bruce's vector is

< 2.11, 4.53 >

The current is moving 3.5 m/s at an angle 60 degrees west of south, which means an overall angle of 210 degrees, measured counterclockwise from the positive x-axis. So, the components of the current's velocity are

[tex]c_x = (3.5 m/s) cos 210^{\circ}=-3.03 m/s\\c_y = (3.5 m/s) sin 210^{\circ}=-1.75 m/s[/tex]

So, the current's vector is

< -3.03, -1.75 >

Finally, we can add the components of the two vectors to find Bruce's actual velocity:

[tex]v_x = b_x + c_x = 2.11 + (-3.03)=-0.92 m/s\\v_y = b_y + c_y = 4.53+(-1.75)=2.78 m/s[/tex]

So, Bruce's actual velocity is

< -0.92, 2.78 >

The magnitude is

[tex]v=\sqrt{(-0.92)^2+(2.78)^2}=2.93 m/s[/tex]

And the direction is

[tex]\theta=180^{\circ} - tan^{-1} (\frac{v_y}{v_x})=180^{\circ} - tan^{-1}(\frac{2.78}{-0.92})=180^{\circ}-71.7^{\circ}=108.3^{\circ}[/tex]

< 2.11, 4.53 >, < -3.03, -1.75 >, <2.93 cos 108.26, 2.93 sin 108.26 >

Answer:

option A

Step-by-step explanation:

We can find the standard form by expanding the equation:

y = 3(x-4)^2 - 22

y = 3(x^2 - 8x + 16) - 22

y = 3x^2 - 24x + 48 - 22

y= 3x^2 - 24x + 26

Answer:

  The area of the triangle is 0.5 square units more than the area of the parallelogram.

Step-by-step explanation:

The vertical sides of the parallelogram are 3 units long and separated by 2 units. Hence the area of that figure is 3×2 = 6 square units.

The leg lengths of the right triangle are each

  √(2^2 + 3^2) = √13

so the area of the triangle is ...

  A = (1/2)(√13)^2 = 13/2 = 6.5

The triangle has area 0.5 square units more than the parallelogram.

Answer:

  range of f(x) = [-4, -2) ∪ [2, 8)

  a+b+c+d = -4

Step-by-step explanation:

The graph is attached. The range is the vertical extent of the function. It is defined at f(0) = -4 and f(2) = 2.

The limits f(2-) and f(4-) are -2 and 8, respectively, so the graph has open circles there. These are the ends of the two half-open intervals that make up the range of the function.

The portion of the graph in the domain [4, 7) is included in the range [2, 8), so no special treatment is needed for that piece of the function.

By the binomial theorem,

[tex](x+y)^8=\displaystyle\sum_{n=0}^8\binom8nx^{8-n}y^n[/tex]

The [tex]x^3y^5[/tex] term occurs for [tex]n=5[/tex]; this gives the term

[tex]\dbinom85x^{8-5}y^5=\dfrac{8!}{5!(8-5)!}x^3y^5=56x^3y^5[/tex]

so the coefficient is 56.

ANSWER

[tex]x = \frac{9}{2} [/tex]

[tex]x - 3x = - 5 - 4[/tex]

[tex] - 2x = - 9[/tex]

[tex]x = \frac{9}{2} [/tex]

Check for extraneous solution.

[tex]| \frac{9}{2} + 4| = \frac{27}{2} - 5[/tex]

[tex] \frac{17}{2} = \frac{17}{2} [/tex]

This is the real solution.

Or

[tex] - (x + 4)= 3x - 5[/tex]

This implies that:

[tex]x + 4= - 3x + 5[/tex]

Group similar terms:

[tex]x + 3x= 5 - 4[/tex]

[tex]4x = 1[/tex]

[tex]x = \frac{1}{4} [/tex]

Check for extraneous solution

[tex]| \frac{1}{4} + 4| \ne \frac{3}{4} - 5[/tex]

This is an extraneous solution.

Answer:B.) Bisector Of An Angle

Step-by-step explanation:

Angle bisectors are lines that bisect the considered angle. The correct option is B.

Angle bisectors are lines that bisect the considered angle. Bisect refers to splitting into two equal parts. Therefore, the bisected parts of the considered angle are half of the original angle.

As the angle bisector is a line, that is exactly between the two rays of an angle, therefore, it can be concluded that the geometric object is the angle bisector or  Bisector of an angle.

The geometric object is defined as the set of all points in a plane that are equidistant from the two sides of a given angle is the angle bisector.

Hence, the correct option is B.

Answer:

12.3

Step-by-step explanation:

In order to find the solution.

1. You need to memorize the formula for the area of a sector, which is

   (central angle/360) * pi (r)^2

2. You then plug in the variables carefully.

    * You were given the diameter. Transform the diameter into radius by diving the diameter by two

     (200/360) * pi (2.65)^2

3. Simplify and round to nearest tenth

    12.3

The area of a sector with a central angle of 200 degrees and a diameter of 5.3 cm can be found by first finding the area of the full circle and then scaling it by the ratio of the central angle to the full circle angle (360 degrees). The final answer is approximately 12.2 cm².

First, let's clear up some definitions. A sector is a part of a circle, defined by two radii and their enclosed arc. The central angle here is the angle at the centre of the circle formed by the two radii.

Start by calculating the radius of the circle. Given the diameter is 5.3 cm, the radius would be half of that, which is 2.65 cm.

The area ('A') of a full circle is calculated by the formula A = πr² where 'r' is the radius. Substituting the values to find the area of the full circle, we get A = π * (2.65 cm)² = 22.02 cm².

Since we are not interested in the area of the full circle but rather a sector of the circle, we need to scale this area down by the ratio of the central angle of the sector to the full angle of the circle (360 degrees). So, the area of the sector is (200/360) * 22.02 cm² = 12.2 cm².

So, the area of the circle sector is approximately 12.2 cm² when rounded to the nearest tenth.

[tex]\frac{9}{20}[/tex]

Step-by-step explanation:

We want probability that 1st is girl AND 2nd is girl as well.

In probability "AND" means multiplication and "OR" means "addition".

We find the probabilities separately and multiply them together, since "AND".

=9/10

=2/4

P(both girls) = 9/10 * 2/4 =9/20

To solve this problem we will use Heron's formula:

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where [tex]a, \ b \ and \ c[/tex] are the side lengths of the triangle and [tex]s[/tex] is the semiperimeter (half the perimeter of the triangle). We know that:

[tex]Perimeter \ P=\triangle PSQ=PS+PQ+SQ: \\ \\ \triangle PSQ=P=50 \\ \\ Semiperimeter \ s: \\ \\ s=\frac{P}{2}=25[/tex]

Also:

[tex](I) \ PS=SQ \\ \\ (II) \ SQ-PQ = 1 \\ \\ (III) \ PS+PQ+SQ=50 \\ \\ \\ (I) \ into \ (III): \\ \\ SQ+PQ+SQ=50 \\ \\ \therefore (IV) \ 2SQ+PQ=50 \\ \\ From \ (II): \\ \\ PQ=SQ-1 \\ \\ (II) \ into \ (IV): \\ \\ 2SQ+(SQ-1)=50 \\ 3SQ-1=50 \\ 3SQ=51 \\ \\ \boxed{SQ=17} \\ \\ \boxed{PS=17} \\ \\ PQ=SQ-1=17-1 \therefore \boxed{PQ=16}[/tex]

Finally:

[tex]A=\sqrt{s(s-a)(s-b)(s-c)} \\ \\ A=\sqrt{s(s-PS)(s-SQ)(s-PQ)} \\ \\ A=\sqrt{s(s-17)(s-17)(s-16)} \\ \\ A=\sqrt{25(25-17)(25-17)(25-16)} \\ \\ \boxed{A=120}[/tex]

The selection of "Yes" or "No" to state whether each data set is likely to be normally distributed is as follows: A) No. B) Yes. C) Yes. D) No

1. The number of coupons used at a supermarket is likely to follow a discrete distribution rather than a normal distribution. Customers may use 0, 1, 2, or more coupons, but the number of coupons used is not continuous and typically has a lower bound of 0. The distribution may be skewed to the right with a large number of transactions involving no coupons and a decreasing frequency as the number of coupons increases.

2. The weights of pumpkins are likely to be normally distributed because they are a result of many different factors, such as genetics, soil quality, water intake, etc., which tend to produce a bell-shaped curve when combined. This is an example of a continuous measurement that can be modeled well with a normal distribution.

3. The number of raisins in each 8-oz box is likely to be normally distributed due to the central limit theorem. Although the distribution of raisins per box might be uniform or have some other distribution, when the sample size (number of raisins per box) is large, the distribution of the sample mean (total number of raisins in many boxes) will approach a normal distribution. Since an 8-oz box contains a large number of raisins, the count in each box should be approximately normal.

4. The amount of time customers spend waiting in the checkout line is likely not to be normally distributed. This is because the waiting time is bounded below by zero and may have an upper limit depending on the store's operating hours or customer patience. The distribution of waiting times is often skewed to the right, with many customers experiencing short waits and a few experiencing longer waits. This results in a distribution with a long tail on the right side, which is not characteristic of a normal distribution.

A function is relationship between two variables in such a way that all the values of x corresponds to values of y.

The given function is f(X)=x and we need to form the function g(x)=1/5x from the function f(x)=x. Because we need to change the value of the function means we are changing y so we need to vertically walk in the graph. If we walk horizontally we might change the value of x.
