EF=5x+15, FG=53 And EG=143 find the value of x
And can you please tell me how to do it?

Answers

Answer 1
I'm assuming EFG is a triangle. In order to solve this problem, you do not have all the information to solve for x in a numerical form. However, if you let variable P equal the perimeter. You can solve for x in terms of P. Perimeter is the sum of all the sides of a shape. First, let's add together all the sides of the triangle. (P = 5x+15+53+143). Add together the common variables so that (5x+211=P). Our next job is to isolate the x. We start by subtracting 211 from both sides. (5x=P-211) Next we divide by 5. [x=(P-211)/5] Therefore, [x=(P-211)/5], assuming P = perimeter

How many different 1010-letter permutations can be formed from 88 identical h's and two identical t's?

Answers

We are given 8 h's and 2 t's.

A permutation of these letters is simply an arrangement in a row.

For example:

h h h t h h t h h h

or 

h t h h h h h h t h


The number of arrangements is equal to the number of pairs of positions we fix for t, the rest of the positions are filled with h:

these positions are :

    (1, 2), (1, 3), (1,4).....                     (1, 10)
           (2, 3), (2,4).....                    (2, 10)
                      (3,4)....                     (3,10)
 
                                                      (9,10)

so the 1st position combined with any of the remaining 9
the 2 position combined with any of the remaining 8
...
the 9th position combined with the remaining 1

this makes 9+8+7+6+5+4+3+2+1=45 positions to place the 2 t's.

Remark: the number of positions for the 2 t's could also have been calculated by C(10, 2)=10!/(8!2!)=(10*9)/2=45

How can I do this with the function (x+2)/x-3
Create a rational function with a linear binomial in both the numerator and denominator.
Part 1. Graph your function using technology. Include the horizontal and vertical asymptotes and the x- and y-intercepts on your graph. Label the asymptotes and intercepts.
Part 2. Show all work to identify the vertical asymptote, the x-intercepts, and the y-intercept.

Answers

The given rational function is
[tex]f(x) = \frac{x+2}{x-3} [/tex]

Part 1
The horizontal asymptote is obtained by either long division or synthetic division. It may be obtained also as
[tex]f(x)= \frac{x-3+5}{x-3} = \frac{x-3}{x-3} + \frac{5}{x-3} =1+ \frac{5}{x-3} [/tex]
Therefore the horizontal asymptote is
y = 1.

The vertical asymptote occurs when the denominator is zero because the function becomes undefined. Set x-3 = 0 to obtain
x = 3.
Therefore a vertical asymptote occurs at x = 3.

The x-intercept occurs when f(x) = y = 0. Set f(x)=0 to obtain
[tex] \frac{x+2}{x-3} =0[/tex]
For x≠3, obtain
x+2=0  => x = -2
The x-intercept is x = -2.

The y-intercept occurs when x=0. Set x=0 in f(x) to obtain
[tex]f(0)= \frac{0+2}{0-3} =- \frac{2}{3} [/tex]
The y-intercept is
y = -2/3

Part 2
The graph of the function is shown below. It identifies the horizontal and vertical asymptotes, the x-intercept, and the y-intercept.

In a group of students 25% are enrolled in physics, 23% in sociology, 17% in chemistry, 14% in political science, 12% in anthropology, and 9% in math. you are going to select an individual from the group of students. the probability of event a is equivalent to the probability that you select someone who studies social science (sociology, political science and anthropology) or physics. what is the probability of the event a’s complement?

Answers

Notice that 25+23+17+14+12+9=100, so among these students there are no 2 studying 2 subjects.

The probabilities of selecting students studying a certain subject are as follows

P(physics)=25/100
P(chemistry)=17/100
P(maths)=9/100

P(sociology)=23/100
P(political sciences)=14/100
P(anthropology)=12/100

since all the sets are disjoint, that is there are no common elements, and since all the students in consideration are enrolled in one these 6 subjects:


P(physics)+P(chemistry)+P(maths)+P(sociology)+P(political sciences)
+P(anthropology)=1

P(a)=P(sociology)+P(political sciences)+P(anthropology)+P(physics)

thus 

P(a')=1-P(a)=P(chemistry)+P(maths)=17/100+9/100=26/100=0.26


Answer: 0.26

The probability of event A's complement, which signifies selecting a student not studying social science or physics, is 26%.

The probability of selecting someone who studies social science (sociology, political science, and anthropology) or physics is the sum of the individual probabilities for those subjects: 23% (sociology) + 14% (political science) + 12% (anthropology) + 25% (physics) = 74%. To find the probability of the event A's complement, which is selecting a student not studying any of these subjects, we subtract the probability of event A from 100%: 100% - 74% = 26%. Therefore, the probability of selecting a student not enrolled in any of the mentioned social science subjects or physics is 26%.

given that (6 3) is on the graph of f(x) find the corresponding point for the function f(-1/2x)

Answers

Answer:

this answer is wrong on plato, trust me

Step-by-step explanation:


We need to find the corresponding y-coordinate for x = -3. Unfortunately, since we don't have additional information about the function f(x), we cannot determine the value of f(-3) and provide the corresponding point.

To find the corresponding point for the function f(-1/2x) when (6, 3) is on the graph of f(x), we need to substitute the x-coordinate of (6, 3) into the function -1/2x and determine the resulting y-coordinate.

Given that (6, 3) is on the graph of f(x), it means that f(6) = 3.

Now let's substitute -1/2x into the function:

f(-1/2x) = f(-1/2 * 6) = f(-3)

Therefore, we need to find the corresponding y-coordinate for x = -3. Unfortunately, since we don't have additional information about the function f(x), we cannot determine the value of f(-3) and provide the corresponding point.

In summary, without more information about the function f(x), we cannot find the corresponding point for the function f(-1/2x) when (6, 3) is on the graph of f(x).

Step-by-step explanation:

The area of the opening will be the sum of the area of the two shapes shown which are rectangle and half ellipse:

[tex]Area =Area_{rectangle}+\frac{1}{2} Area_{Ellipse}[/tex]

The area of the rectangle is:

[tex]Area_{Rectangle}=a*b[/tex]

where:

[tex]a=4ft\\b=2\frac{1}{2}ft[/tex]

we replace values(we convert the mixed fraction to improper fraction by multiplying the whole number part by the fraction's denominator, then add that to the numerator  then write the result on top of the denominator.):

[tex]Area_{Rectangle}=4*2\frac{1}{2} =4*\frac{5}{2}=10[/tex]

The area of the ellipse is:

[tex]Area_{Ellipse}=a*b*\pi[/tex]

where:

[tex]a=Radius1=1\frac{1}{4}ft\\b=Radius2=2ft\\[/tex]

Radius2 will be half the side of the rectangle

we replace the values:

[tex]Area_{Ellipse}=1\frac{1}{4} *2*\pi=\frac{5}{4}*2*\pi=\frac{5}{2}\pi =7.85[/tex]

we calculate now the total area:

[tex]Area =Area_{rectangle}+\frac{1}{2} Area_{Ellipse}\\Area=10+\frac{1}{2}(7.85)=10+3.93=13.93ft^{2}[/tex]

What are the trigonometric identities?

Equations using trigonometric functions that hold true for all possible values of the variables are known as trigonometric identities.

We have the equation,

cos x - (cos x) (sin x) = cos³x

Simplifying,

cos x [ 1 - (sin x) ]  = cos²x (cos x)

1  - sinx = cos²x

1  - sinx = 1 - sin²x

1  - sinx = 1² - sin²x

1  - sinx = (1  - sinx)(1 +sinx)

1 = 1  + sinx

sinx = 0

x = nπ, where n∈I , I → set of integers.

It is not an identity equation.

cos x - (cos x) (sin x) ≠ cos³x

Answers

1) A Pythagorean triples is a set of three integers, a, b, c,  that follow the rule a^2 + b^2 = c^2

2) Assumin c is the diagonal of your rectangle and the hypotenuse of the triangles, you are looking this:

13^2 = a^2 + b^2

=> 169 = a^2 + b^2

Two integer numbers that meet that equality are 5 and 12:

5^2 = 25

a hot air balloon holds 3,249 cubic meters kf helium. the density of the helium is 0.1785 kilograms per cubic meter. how many kilograms of helium does the balloon contain, round to the nearest tenth of a kilogram?

Answers

TO determine the mass of the helium in the balloon, we make use of the density of the gas that is given in the problem and the volume of helium that is present. Density is a property of a material which describes the mass of a material per unit volume. By multiplying the volume to density, we get the mass of the helium gas in the balloon. We do as follows:

Mass = Density x Volume
Mass = 0.1785 kg / m^3 x 3249 m^3
Mass = 579.9465 kg

Therefore, the mass of helium gas in the hot air balloon would be about 579.9 kg.

Step-by-step explanation:

It has been given in the question 4 < 5 < 9 and we have to show 6√5 is between 12 and 18.

For box number 1.

4 < 5 < 9 ⇒ √4 < √5 < √9

For the box number 2.

√4 < √5 < √9    ⇒   2 < √5 < 3

For the box number 3.

we multiply the inequality by 6.

6×(2 < √5 < 3) ⇒ 6×2 < 6×√5 < 6×3

Therefore final answer is 6×2 < 6×√5 < 6×3 ⇒ 12 < 6√5 < 18

Final answer:

The square root of 65 (√65) falls between 8 and 9, as these are the square roots of the closest perfect square numbers (64 and 81 respectively). The range of 12 to 18 provided in the question seems incorrect.

Explanation:

The student's question is referring to the mathematical concept of square roots of numbers. The square root of a number is a value which, when multiplied by itself, yields the original number. In the case of √65, we need to locate it between two perfect square numbers, which are 64 (8^2) and 81(9^2). As a result, √65 should fall between 8 and 9.

However, the interval of 12 and 18 as stated in the question seems to be a mistake, as they are not the correct boundaries for the value of √65. Please verify the numbers in your question.
