Answer:

(9-8i)(-6,-15i) = -174 + 183 i

Step-by-step explanation:

Explanation:-

Given that  the complex numbers

                           (9-8i)(-6,-15i)

multiply           ( 9-8i ) ( -6 -15i)

               =  -54 - 9(-15 i) + 48 i +  120(i)²

               =   -54 + 135 i + 48 i - 120

              =    -174 + 183i

Final answer:-

(9-8i)(-6,-15i) = -174 + 183 i

Answer:

  (x -4)² +(y -2)² = 20

Step-by-step explanation:

The circle is the circumcircle of triangle OAB. Then OA will be a diameter if angle OBA is a right angle. We can check that by looking at the slopes of AB and BA.

  B-O = (6, 6)-(0, 0) = (6, 6)   ⇒   slope = Δy/Δx = 6/6 = 1

  A-B = (8, 4) -(6, 6) = (2, -2)   ⇒   slope = -2/2 = -1

These slopes have a product of -1, so OB ⊥ BA. The hypotenuse (OA) of ΔOBA is the diameter of the circle.

Then the midpoint of the hypotenuse is the center of the circle.

  C = (O +A)/2 = ((0, 0) +(8, 4))/2 = (4, 2)

The equation is ...

  (x -h)² +(y -k)² = r² . . . . . circle with center (h, k) and radius r

The radius is the distance from O to C, so is ...

  r² = 4² +2² = 20

and the equation of the circle is ...

  (x -4)² +(y -2)² = 20 . . . . equation of the circle

Answer:

28.26 in

Step-by-step explanation:

Radius = (1/2) diameter

Radius = (1/2)(9)

Radius = 4.5 in

Circumference = 2πr

Circumference = 2(3.14)(4.5)

Circumference = 28.26 in

Answer:

Step-by-step explanation:

Length of a text can be measured with ruler. Therefore, option C is the correct answer.

Everything around us has a measurement value, from the amount of sugar you put in a cake to the size of a football field. Each thing is measured differently based on its length, weight, volume, or duration. With these measurements, the idea of "Metric System" is introduced.

A ruler, sometimes called a rule, line gauge, or scale, is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure distances or draw straight lines.

Length of a text can be measured with ruler.

Therefore, option C is the correct answer.

when y = x, it means that whatever x is, that is what y is

so if x is 8, then y is 8

if x is -2, then y is -2

Given that,

Half of Robert's piece of wire is equal to of Maria's wire i.e.

[tex]\dfrac{R}{2}=M[/tex] ....(1)

Total length of the wires = 10 feet

ATQ,

[tex]R+M=10[/tex] ....(2)

Use equation (1) in (2).

[tex]R+\dfrac{R}{2}=10\\\\\dfrac{3R}{2}=10\\\\R=\dfrac{20}{3}\\\\R=6.67\ ft[/tex]

So,

[tex]M=\dfrac{6.67}{2}\\\\M=3.33\ ft[/tex]

Hence, this is the required solution.

Answer:

f(x)= 2 ³√x+4

Step-by-step explanation:

Thats the answer

The equation of the function is f(x) = 2∛x -4.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

We will take two points from the graph substitute in each function.

So, the points are (0, -4) and (1, -2).

1. f(x) = ∛x -4

For x= 0

f(x) = ∛0 -4 = -4

and, For x= 1

f(x) = ∛1 -4 = 1 -4 = -3  (False)

2. f(x) = 2∛x -4

For x= 0

f(x) = 2∛0 -4 = -4

and, For x= 1

f(x) = 2∛1 -4 = 2 -4 = -2 (True)

3. f(x) = 2∛x +4

For x= 0

f(x) = 2∛0+4 = 4

and, For x= 1

f(x) = 2∛1 +4 = 2+4 = 6 (False)

4. f(x) = ∛x +4

For x= 0

f(x) = ∛0 +4 = 4

and, For x= 1

f(x) = ∛1 +4 = 1 +4 = 5 (False)

Thus, the required function is f(x) = 2∛x -4.

Step-by-step explanation:

Answer:

See attachment for plot

Step-by-step explanation:

The attachment has enough information to solve for only question (4).

Solving (4), we have:

[tex]W = (-1,-1)[/tex]

[tex]X = (4,1)[/tex]

[tex]Y = (4,5)[/tex]

[tex]Z =(1,7)[/tex]

Required

Reflect over the x-axis

When a point (x,y) is reflected over the x-axis, the resulting point is (x,-y)

i.e.

[tex](x,y) => (x,-y)[/tex]

So, we have:

[tex]W = (-1,-1)[/tex] ==> [tex]W' =(-1,1)[/tex]

[tex]X = (4,1)[/tex] ==>[tex]X' = (4,-1)[/tex]

[tex]Y = (4,5)[/tex] ==> [tex]Y' =(4,-5)[/tex]

[tex]Z =(1,7)[/tex] ==> [tex]Z' = (1,-7)[/tex]

So, we plot on a grid, the following points:

[tex]W' =(-1,1)[/tex]

[tex]X' = (4,-1)[/tex]

[tex]Y' =(4,-5)[/tex]

[tex]Z' = (1,-7)[/tex]
