Answer:

The length of side BC is 2.8 units

Step-by-step explanation:

* Lets revise how to find the distance between two points

- If there are two points their coordinates are (x1 , y1) and (x2 , y2),

 then we can find the distance between them by this rule:

 d = √[(x2 - x1)² + (y2 - y1)²]

- Now lets solve the problem

∵ B = (3 , 3)

∵ C = (5 , 1)

- To find the length of BC use the rule of the distance above

- Let point B is (x1 , y1) and point C is (x2 , y2)

∵ x1 = 3 and x2 = 5

∵ y1 = 3 and y2 = 1

∴ BC = √[(5 - 3)² + (1 - 3)²]

∴ BC = √[(2)² + (-2)²]

∴ BC = √[4 + 4] = √8 = 2.8 units

* The length of side BC is 2.8 units

Answer:

c = - 2, c = 7

Step-by-step explanation:

Given

c² - 14 = 5c ( subtract 5c from both sides )

c² - 5c - 14 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 14) which sum to give the coefficient of the c- term (- 5)

The factors are - 7 and + 2, since

- 7 × 2 = - 14 and - 7 + 2 = - 5, hence

(c - 7)(c + 2) = 0

Equate each factor to zero and solve for c

c - 7 = 0 ⇒ c = 7

c + 2 = 0 ⇒ c = - 2

ANSWER

The paths do not cross each other.

EXPLANATION

The equation that models one of the paths is

[tex]y = - 6x - 5[/tex]

and the other is modeled by:

[tex]y = - 4 {x}^{2} - 13x - 12[/tex]

We equate the two equations and solve for their point of intersection.

[tex]- 4 {x}^{2} - 13x - 12 = - 6x - 5[/tex]

[tex]- 4 {x}^{2} - 13x + 6x- 12 + 5 =0[/tex]

[tex]- 4 {x}^{2} - 7x- 7 =0[/tex]

[tex]4 {x}^{2} + 7x + 7 =0[/tex]

The discriminant is

[tex]D= {b}^{2} - 4ac[/tex]

[tex]D= {7}^{2} - 4(4)(7) = - 63[/tex]

The discriminant is negative so the equation has no real roots.

This means that, the two paths do not cross.

Answer:

Yes, because the sum of all of the probabilities is 1.

Step-by-step explanation:

The given probability equation is:

[tex]P(x)=\frac{2x-1}{16}[/tex], where x belongs to {1,2,3,4}.

[tex]P(1)=\frac{2(1)-1}{16}=\frac{1}{16}[/tex]

[tex]P(2)=\frac{2(2)-1}{16}=\frac{3}{16}[/tex]

[tex]P(3)=\frac{2(3)-1}{16}=\frac{5}{16}[/tex]

[tex]P(4)=\frac{2(4)-1}{16}=\frac{7}{16}[/tex]

Let us sum all the probabilities to obtain;

[tex]P(1)+P(2)+P(3)+P(4)=\frac{1}{16}+ \frac{3}{16}+\frac{5}{16}+\frac{7}{16}[/tex]

[tex]P(1)+P(2)+P(3)+P(4)=\frac{1+3+5+7}{16}[/tex]

[tex]P(1)+P(2)+P(3)+P(4)=\frac{16}{16}[/tex]

[tex]P(1)+P(2)+P(3)+P(4)=1[/tex]

Since the sum of all the probabilities is 1, it is a probability distribution

Answer: -2, 0, 4

Set the equation equal to zero.

x³ - 2x² - 8x = 0

Factor out x in the equation, since all the terms (x³, -2x², and -8x) are divisible by x. You can check your accuracy using the Distributive Property.

x(x² - 2x - 8) = 0

Factor out the polynomial. To do this, find two numbers that multiply to get the last term, -8, and add together to get the middle term, -2. In this case, those two numbers are -4 and 2 (-4 × 2 = -8 and -4 + 2 = -2). Don't forget about the x that was factored out before!

x(x - 4)(x + 2) = 0

Set each factor equal to zero and solve for x. The factors in the equation are x, (x - 4), and (x + 2).

        x = 4

        x = -2

The zeros of the polynomial function are -2, 0, and 4.

40% of the figure is shaded.

The image depicts many grids. These small squares has 10 rows and 10 columns. So, the total number of squares are:

10 x 10=100 squares.

Out of 100 squares, 4 rows and their 10 columns are shaded. So,

4*10=40 squares

So, 40 squares are shaded. To find the percentage we can use the formula:

Shaded/ Total Squares x 100

= 40/100 x 100

= 40%

Therefore, 40 percent of the figure is shaded.

To find what percent of a figure is shaded, calculate the shaded area divided by the total area and multiply by 100. In probability distributions, shading indicates the probability that a variable falls within a specific range, such as the 80th or 90th percentile of a distribution.

To determine what percent of the figure is shaded, one must first understand the concept of percentage calculations. The percentage is computed by dividing the part (shaded area) by the total area, then multiplying by 100. In the case of probability distributions, the shaded area represents a probability, such as the probability of a variable falling between two values, or the specific percentile of a distribution.

For example, if we have a graph with a horizontal axis for X, and we need to shade the region corresponding to a certain probability or percentile, we need to identify the region under the curve that equates to that percentage. This could involve calculating the area between two x-values or finding a value that corresponds to a given area under the curve, such as the 80th percentile or 90th percentile. To express the result as a percentage, multiply the probability by 100.

Sometimes, the question may provide specific conditions, such as indicating that the shaded area under one curve is equal to the area of another shape, like a rectangle or another curve. In this case, we can assume the two percentages are equal and express the probability of one as the same percentage as the other.

So, the best value here refers to the cheapest napkins. To find their price per unit , we need to divide the cost of the pack by the number of packs

[tex]\frac{11.16}{4}= \$2.79\\\frac{17.94}{6}=\$ 2.99\\\frac{24.96}{8} =\$3.12\\\frac{39.75}{15}=\$2.65[/tex]

You can observe that the cheapest price is $2.65.

Therefore, the best choice is D. 15 packs for $39.75, because ti gives the best offer per pack.

Answer:

Part 1) [tex]sin(\theta)=-\frac{5\sqrt{61}}{61}[/tex]  or [tex]sin(\theta)=-\frac{5}{\sqrt{61}}[/tex]

Part 2) [tex]csc(\theta)=-\frac{\sqrt{61}}{5}[/tex]

Part 3) [tex]cot(\theta)=\frac{6}{5}[/tex]

Step-by-step explanation:

we know that

The point (-6,-5) lies on the III Quadrant

so

sin(theta) is negative

csc(theta) is negative

cot(theta) is positive

Part 1) Find the sine of angle theta

we know that

The function sine is equal to divide the opposite side to the angle theta by the hypotenuse

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

we have

[tex]x=6\ units,y=5\ units[/tex]

Applying the Pythagoras Theorem

[tex]r^{2}=x^{2}+y^{2}[/tex]

substitute

[tex]r^{2}=6^{2}+5^{2}[/tex]

[tex]r^{2}=61[/tex]

[tex]r=\sqrt{61}\ units[/tex] -----> the hypotenuse

substitute

[tex]sin(\theta)=\frac{5}{\sqrt{61}}[/tex]

Simplify

[tex]sin(\theta)=\frac{5\sqrt{61}}{61}[/tex]

Remember that the sin(theta) is negative

so

[tex]sin(\theta)=-\frac{5\sqrt{61}}{61}[/tex]

Part 2) Find the cosecant of angle theta

we know that

The function cosecant is equal to divide the hypotenuse by the opposite  side to the angle theta

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

we have

[tex]sin(\theta)=-\frac{5}{\sqrt{61}}[/tex]

so

[tex]csc(\theta)=-\frac{\sqrt{61}}{5}[/tex]

Part 3) Find the cotangent of angle theta

we know that

The function cotangent is equal to divide the adjacent side to the angle theta by the opposite side to the angle theta

[tex]cot(\theta)=\frac{x}{y}[/tex]

we have

[tex]x=6\ units,y=5\ units[/tex]

substitute

[tex]cot(\theta)=\frac{6}{5}[/tex]

The exact values of sin theta, csc theta, and cot theta for a point (-6, -5) on the terminal side are -5/sqrt(61), sqrt(61)/-5, and 6/5 respectively.

In this problem we have a point (-6, -5) on the terminal side of theta. The x-coordinate corresponds to the cosine of theta and the y-coordinate corresponds to the sin theta.

Step-by-step explanation:

The scale of equal intervals is characterized by a common and constant unit of measure that assigns a number equal to the number of units equivalent to that of the magnitude of the observed element. It is important to note that the zero point in the scales of equal intervals is arbitrary, and does not reflect at any moment absence of the magnitude that we are measuring.

This scale, besides having the characteristics of the ordinal scale, we find that the assignment of the numbers to the elements is so precise that we can determine the magnitude of the intervals (distance) between all the elements of the scale. Undoubtedly, we can say that the scale of intervals is the first truly quantitative scale and the characters that have this scale can be calculated all the statistical measures except the coefficient of variation.

The data is classified into classes divided into equivalent intervals. The range is then divided by the number of classes, which gives the common difference.

1. Define the number of equals intervals .

Each interval increase 0.9.

Among these possible outcomes only 3 are even numbers

S = {2, 4, 6}

So the probability of obtaining an even number is

[tex]P = \frac{3}{6}\\\\P = \frac{1}{2}[/tex]

Then, the probability of obtaining a number other than 2 is:

[tex]P = \frac{5}{6}[/tex].

If 2 launches are made then the events are independent,

Step-by-step explanation:

Answer:

y = (-1/6)x^2

Step-by-step explanation:

Original function and graph:  y = x^2

Reflection across the x-axis is y = -x^2

Vertical scaling by a factor of 1/6:    y = (-1/6)x^2

The given parabola y=x^2 when reflected over the x-axis becomes y=-x^2. After applying a vertical scale factor of 1/6, it becomes y = -(1/6)x^2.

The parabola given, y=x^2, when reflected across the x-axis, results in a graph of y = -x^2.

Then, when we apply vertical scaling by a factor of 1/6, we have to multiply the y-values by this factor. If y = -x^2 is our equation after reflecting, then after scaling, it becomes y = -(1/6)x^2.

A key point to remember is that when a parabola is reflected over the x-axis, it flips upside down. Then, when it's vertically scaled by a factor, we multiply the y-values by the factor, which stretches or squishes the graph depending on the factor's value.
