4 is the value of x ,on solving that  m and n are in perpendicular lines. calculating  the slope of AB is explained below,

in  order to find the slope of AB. the formula is used as

m=(y2-y1)/(x2-x1)

on substituting we get,

m=(8-6)/(4-(-2))

m=2/6

m=1/3

Calculating CD  in which it is perpendicular to AB

hence, it should contains the negative reciprocal of the slope of AB, mathematically as ,

m1 * m2= - 1  ,condition is applied when m and n  lines to be perpendicular

hence,

m/3=-1

m = - 3    

therefore  CD will have a slope of -3

in which CD  can be expressed as part of the each  line:

y=-3x+b, on solving  for b using point C, (8,12)...

12 = - 3(8) + b

12= - 24 + b

36=b

hence, the line of CD is :

y = - 3x + 36  

the x coordinate is calculated  for (x,24),

hence,

y=24

24=-3x+36

3x+24=36

3x=12

x=4

therefore the value of x = 4 when the 2 lines are in parallel lines .

Answer:

g( [tex]\frac{3}{2}[/tex] ) = - [tex]\frac{35}{4}[/tex]

Step-by-step explanation:

substitute x = [tex]\frac{3}{2}[/tex] into g(x) , that is

g( [tex]\frac{3}{2}[/tex] )

= - 2( [tex]\frac{3}{2}[/tex] )³ - [tex]\frac{4}{3}[/tex] × [tex]\frac{3}{2}[/tex]

= - 2 × [tex]\frac{27}{8}[/tex] - 2

The scale factor is 8 : 1 ( option A)

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller). For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2. The new sides will be 4cm and 8cm. Therefore the scale factor is 2

To calculate scale factor we divide the new shape size by original shape .

The new shape is 24m and the original shape is 3m.

scale factor = 24m/3m = 8/1

therefore scale factor = 8 : 1

This equation has no solution

To solve this problem, you will need to use the rules of complex numbers to multiply and simplify the given expressions.

First, let's simplify each of the given expressions:

(a+ib) (3 + 4i ) = a3 + a4i + ib3 + ib4i

= (3a - 4b) + (4a + 3b)i

(2 + i ) (2- i ) = (2*2) + (2(-1))i + (1*2) + (1(-1))i

= (4 - 1) + (2 - 1)i

= 3 + i

Now, we can set the two expressions equal to each other and solve for a and b:

(3a - 4b) + (4a + 3b)i = 3 + i

3a - 4b = 3

4a + 3b = 1

We can solve this system of equations using any method you prefer, such as substitution or elimination. One way to solve this system is to eliminate one of the variables by multiplying the first equation by 4 and the second equation by -3:

12a - 16b = 12

-12a - 9b = -3

This simplifies to:

0 = 9

This equation has no solution, so the original expression cannot be true. This means that a²+b² is not defined in this case.

The probability of choosing a ball numbered 25 in a lottery game that contains 24 balls numbered 1 through 24 is 0.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event will not occur and 1 indicating that the event will definitely occur.

Since a lottery game contains 24 balls numbered 1 through 24, it does not contain the ball numbered 25. So it can not be chosen at all.

probability = 0

Therefore, the probability of choosing a ball numbered 25 is 0.

The two numbers which are 14 and -5 give you -70 when multiplied but when added give you 9

An equation is an expression composed of variables and numbers linked together by mathematical operations.

Let x and y represent the unknown numbers

The two numbers give -70 when multiplied, hence:

xy = -70   (1)

The two numbers give 9 when added, hence:

x + y = 9   (2)

x = 9 - y

put x = 9 - y in equation 1:

(9 - y)y = -70

9y - y² = -70

y² - 9y - 70 = 0

y = -5 or 14

when y = -5; x = 9 - (-5) = 14

when y = 14; x = 9 - 14 = -5

Answer:

a = 23

c= 13

this is the answer

The required value of c is c = 1.407 which satisfies the Mean Value Theorem.

The Mean Value Theorem states that if a function f is continuous on a closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that f'(c) = (f(b) - f(a))/(b-a).

As per the given question, [tex]f(x) = (5x-10)^{2/3}[/tex], a=0, and b=2.

To find the values of c that satisfy the Mean Value Theorem, we need to find the derivative of f(x) and then solve the equation f'(c) = (f(2) - f(0))/(2-0) for c.

The derivative of f(x) is f'(x) = 5 × (2/3) [tex]\dfrac{1}{(5x-10)^{1/3}}[/tex]  = (10/3) × [tex]\dfrac{1}{(5c-10)^{1/3}}[/tex]

Substituting this into the equation above, we get

(10/3) × [tex]\dfrac{1}{(5c-10)^{1/3}}[/tex] =  [tex]\dfrac{0 - 10^{2/3}}{2-0}[/tex]

(10/3) × [tex]\dfrac{1}{(5c-10)^{1/3}}[/tex] = [tex]-\dfrac{10^{2/3}}{2}[/tex]

Solving this equation for c, we find that c =38/27≈ 1.407.

Thus, the value of c that satisfies the Mean Value Theorem is c = 1.407.

Answer: < B is larger than a right angle

Step-by-step explanation:

The required equation of the lines in the slope-intercept form can be obtained as y = -0.5x + 3, y = 2.5x + 1, y = -4x - 5, y = -x + 2, y = 2/3x - 4 and y = x.

A straight line can be written in the slope-intercept form as, y = mx + c.

In order to obtain the slope, the ratio of the difference of the coordinates are taken and c is the y-intercept which can be found by substituting x = 0 in the equation.

The  equation of the lines given in the graph can be written as,

(4) Slope of the line is m = (3 - 0)/(0 - 6)

⇒ m = -0.5

And, y-intercept is 3

Then, the slope-intercept equation can be written as y = -0.5x + 3.

(5) Slope of the line is m = (1 - (-4))/(0 - (-2))

⇒ m = 5/2 =2.5

And, the y-intercept is 1.

Then, the slope-intercept equation can be written as y = 2.5x + 1.

(6) Slope of the line is m = (-5 - 3)/(0 - (-2)) = -4

And, the y-intercept is -5.

Then, the slope-intercept equation can be written as y = -4x - 5.

(7) Slope of the line is m = (2 - 0)/(0 - 2) = -1.

And, the y-intercept is 2.

Then, the slope-intercept equation can be written as y = -x + 2

(8) Slope of the line is m = (-4 - 0)/(0 - 6) = 2/3

And, the y-intercept is -4.

Then, the slope-intercept equation can be written as y = 2/3x - 4.

(9) Slope of the line is m = (6 - 0)/(6 - 0) = 1.

And, the y-intercept is 0.

Then, the slope-intercept equation can be written as y = x.

Hence, the equations of the lines can be obtained as y = -0.5x + 3, y = 2.5x + 1, y = -4x - 5, y = -x + 2, y = 2/3x - 4 and y = x.

In the given situation there are 144 possible ways for the nine representatives at the table.

We will first determine how many different options there are to seat the delegates of the three nations at the table.

We can arrange the three delegates we have for England in 3! = 6 different ways.

We can arrange the four delegates we have for Germany in 4! = 24 different ways.

We can organize the two representatives we have for France in 2! = 2 different ways.

The total number of arrangements for all nine delegates is obtained by multiplying the number of arrangements for each country's representatives.

6 x 24 x 2 = 288 ways

However, because the table is round, two configurations are deemed identical if they can both be created by rotating one.

To put it another way, the configurations are identical to one another and are not counted individually.

The total number of configurations divided by the number of identical arrangements gives the number of ways to position all nine representatives around the table (also known as rotations).

288 / 2 = 144

The nine representatives can be seated at the table in 144 different ways.

Because 144 is an even number, it should be noted that there are actually twice as many possible methods to solve the problem (144 x 2 = 288), or 540 options.

Therefore, in the given situation there are 144 possible configurations for the nine representatives at the table.

a. The probability of guessing exactly three answers correctly is 0.0879.

b. The probability of guessing at least three answers correctly is 0.1035.

c. The probability of guessing less than three answers correctly is 0.8965.

Total number of questions = 5

Possible answer = 4

Therefore, the probability that the question is correct = 1/4 = 0.25

By using the Binomial Probability distribution

P(X=x) = ⁿCₓ * p^x * (1-p)^n-x

a) P(X = 3) = ⁵C₃ * (0.25)^3 * (1-0.25)^5-3

P(X = 3) = 0.0879

Therefore, the probability of guessing exactly three answers correctly is 0.0879.

b) P(X ≥ 3) = 1 - P(X ≤ 2)

P(X ≥ 3) = 1 - P(X = 0) + P(X = 1) + P(X = 2)

P(X ≥ 3) = 1 - (0.2373 + 0.3955 + 0.2637)

P(X ≥ 3) = 1 - 0.8965

P(X ≥ 3) = 0.1035

Therefore, the probability of guessing at least three answers correctly is 0.1035.

c) P(X < 3) = P(X ≤ 2)

P(X < 3) = 0.8965

Therefore, the probability of guessing less than three answers correctly is 0.8965.
