Answer:

The distance between the two given complex numbers = 9

Step-by-step explanation:

Explanation:-

Step(i):-

Given  Z₁ = 9 - 9 i    and Z₂ = 10 -9 i

Let A and B represent complex numbers Z₁ and Z₂ respectively on the argand plane

⇒ A =  Z₁ = x₁ +i y₁ = 9 - 9 i and

    B = Z₂ = x₂+ i y₂ = 10 -9 i

Let (x₁ , y₁) = ( 9, -9)

     (x₂, y₂) = (10, -9)

Step(ii):-

The distance between the two points are

    A B   =   [tex]\sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2} }[/tex]

    A B =   [tex]\sqrt{(10 - 1)^{2}+(-9 - (-9))^{2} }[/tex]

   AB   = [tex]\sqrt{(9)^{2} +(-9+9)^{2} }[/tex]

  AB    =  √81 = 9

Conclusion:-

The distance between the two given complex numbers = 9

Just finished Quiz 4: Complex Numbers, of which this was one of the questions.

Answer:

47. 1 inches ; where inches ⇒ units

Step-by-step explanation:

Consider the Circumference as such;

[tex]Diameter - 15 inches,\\Circumference - 2\pi r, r - radius,\\\\2\pi r = \pi d, d - diameter ( considering, 2 * r = diameter )\\\\Circumference = \pi * d = \pi * diameter = \pi * 15 = ( About ) 47.1 inches\\Solution; Circumference = ( About ) 47.1 inches[/tex]

From this we can tell that ⇒ Answer; 47. 1 inches, where inches - units

Answer:

47. 1

Step-by-step explanation:

The equation for the circumference of a circle is C = pi X diameter.

Answer:

see explanation

Step-by-step explanation:

Inequalities of the form | x | < a have solutions of the form

- a < x < a

Given

| x - 4 | < 3 , then

- 3 < x - 4 < 3 ( add 4 to the 3 intervals )

1 < x < 7

Thus x > 1 or x < 7

The solution of the given inequality is x < 7 or x > 1.

To solve the inequality Ix - 4| < 3, we can break it down into two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: x - 4 > 0

In this case, we don't need to consider the absolute value because the expression inside it is already positive.

So we have:

x - 4 < 3

Adding 4 to both sides:

x < 3 + 4

x < 7

Case 2: x - 4 < 0

In this case, the expression inside the absolute value is negative, so we need to negate it when removing the absolute value. Therefore, we have:

-(x - 4) < 3

Expanding the negation:

-x + 4 < 3

Subtracting 4 from both sides:

-x < 3 - 4

-x < -1

Dividing both sides by -1 and flipping the inequality sign:

x > 1

Combining the results from both cases, we have the solution:

x < 7 or x > 1

In interval notation, the solution is (-∞, 1) U (7, +∞).

Hence the solution of the given inequality is x < 7 or x > 1.

Answer:

Step-by-step explanation:

Step-by-step explanation:

x:y=3:7

x+y=180

3+7=10

180/10=18

to find x

18*3=54

x+10+z=180

54+10+z=180

64+z=180

z=180-64

z=116°

The measure of angle z of the cyclic quadrilateral will be 116 degrees.

If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral.

A cyclic quadrilateral is shown.

x / y = 3 / 7

y = 7x / 3

We know that the sum of the opposite angles of the cyclic quadrilateral is 180 degrees. Then the equation will be

x + y = 180°

x + 7x/3 = 180°

10x/3 = 180°

x = 54°

Then another equation is given as,

x + 10° + z = 180°

54° + 10° + z = 180°

z = 116°

The measure of angle z of the cyclic quadrilateral will be 116 degrees.

Answer:

4.5 ft

Step-by-step explanation:

Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,

18/x = 8/2

Let's solve for x as required.

We have,

18/x = 8/2

=>Cross multiply:

18 × 2 = 8 × x

36 = 8x

=>Divide both sides by 8

36/8 = x

4.5 = x

x = 4.5 ft

The first option is our answer = 4.5 ft

Answer:

-8.5

Step-by-step explanation:

17/2 = 8.5

f = 8.5

f -1(17) = 8.5 -17 = -8.5

-8.5 is your answer

The value of [tex]f^{-1}(17)[/tex] is 2.

From the definition of function we know that if f(x) = y , where x and y are two real values having range of (-∝,+∝) , then

[tex]f^{-1}(y) = x[/tex]

Thus in the problem, it is given that f(2) = 17 .

Using the above identity, we can find the value of [tex]f^{-1}(17)[/tex]

∴  [tex]f^{-1}(17) = 2[/tex]

Step-by-step explanation:

Answer:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]

Step-by-step explanation:

If we call "x" the number of call minutes used with this plan, the piecewise function used to describe it must represent;

a) a constant value of 29 for any x value smaller than or equal to 250

b) a line with positive slope of 0.35 for the region with x larger than 250. The mathematical representation of such increasing straight line, should be given by a line of slope m = 0.35, and containing the point (250, 29) which is the starting point for this right hand side portion of the domain:

[tex]f(x)=0.35(x-250)+29\\f(x)=0.35 x-87.5+29\\f(x)=0.35 x-58.5[/tex]

So the function should look like:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {29+0.35(x-250)\,\,for \,x>250}} \right.[/tex]

or as shown above, in a more simplified form:

[tex]f(x)=\left \{ {{29\,\,for \,\,x\,\leq 250 } \atop {0.35x-58.5\,\,\,for \,\,x>250}} \right.[/tex]

The answer would be [tex]3^{2}[/tex].

Step-by-step explanation:

-Solve the following equation:

[tex]3^{-6} \times ( 3^{4} \div 3^{0})^{2}[/tex]

-When dividing integers, the exponents would subtract each other. So, you subtract exponent [tex]0[/tex] and [tex]4[/tex]:

[tex]3^{-6} \times ( 3^{4} \div 3^{0})^{2}[/tex]

[tex]3^{-6} \times ( 3^{4})^{2}[/tex]

-Simplify [tex]3^{4}[/tex] by the exponent [tex]2[/tex]:

[tex]3^{-6} \times ( 3^{4})^{2}[/tex]

[tex]3^{-6} \times 3^{8}[/tex]

-When multiplying integers, the exponent would add up together. So, you would add [tex]-6[/tex] and [tex]8[/tex]:

[tex]3^{-6} \times 3^{8}[/tex]

[tex]3^{2}[/tex]

So, the answer is [tex]3^{2}[/tex].
