Answer 2

Point x is -3 + 2i , point w is 4 + 0i and point z will be 0 + -4i.

What is a complex number?

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

The idea of a complex number has come by solving a quadratic equation that has root as negative under root.

If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).

Given points, x,y, and z in a complex plan where an x-axis is a real number and the y-axis is an imaginary (i.e. i ) number.

So,

Point x is 3 units to the negative side and 2 units up so its coordinate will be (-3, 2i) so -3 + 2i.

Point w is 4 units to the positive side and 0 units up so its coordinate will be (4,0i) so 4 + 0i.

Point z is 4 units downside so its coordinate will be (0,-4i) so  0 + -4i.

Work out the total area of the regions shaded in the diagram.
Give your answer correct to 1 decimal place.

Answers

Answer:

Area of the shaded portion = 54.5 cm²

Step-by-step explanation:

Solve first for the area of the circle:

[tex]area \: of \: circle = \pi {r}^{2} \\ = \pi( \frac{d}{2} )^{2} \\ = \pi( \frac{10}{2} )^{2} \\ = 25\pi \: or \: 78.5398 {cm}^{2} [/tex]

Then, compute for the area of the triangle:

[tex]area \: of \: triangle = \frac{1}{2} \times base \times height \\ = \frac{1}{2} ( {8})(6) \\ = 24 {cm}^{2} [/tex]

Since we only needed the shaded portion, we have to subtract the area of the triangle from the area of the circle

[tex]25\pi {cm}^{2} - 24 {cm}^{2} = 54.5398 {cm}^{2} [/tex]

What is equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, Mario received y text messages each minute for 10 minutes yesterday and received t text messages each minute for 20 minutes today.

Number of  text messages for yesterday = 10y

Number of  text messages for today = 20t

Total = 10y+20t

Hence, The total number of  text messages he received for two days is  10y+20t

The distance from C to D is 24 miles. The distance from B to C is 2/3 of the distance from C to D. The distance from A to B is 3/8 of the distance from B to C. What is the distance from A to B?

Answers

Answer:

AB is 6 miles

Step-by-step explanation:

Here, we want to get AB

From the question;

CD = 24

BC = 2/3 * 24 = 16

AB = 3/8 * BC

AB = 3/8 * 16

AB = 6 miles

The perimeter of a rectangle is forty inches. The length is
two inches more than three times the width. Find the dimensions of
the rectangle.

Answers

Let Width (inches)  = X

Let Length (inches) = 3x + 2

40 = (x) + (3x + 2) + (x) + (3x +2)

40 = 8x + 4

-4           -4

36 = 8x

/8     /8

4.5 = x (width)

Length = 3x + 2

length = 3(4.5) + 2

length = 13.5 + 2

length = 15.5 inches

CHECK

40 = 15.5 + 4.5 + 15.5 + 4.5

40 = 20 + 20

40 = 40

m∠1=(3x+8)°​, m∠2=(3x+18)°​, and m∠3=(7x+9)°. What is m∠​3?

Answers

Answer:

87.4°

Step-by-step explanation:

(3x + 8) + (3x + 18) + (7x + 9) = 180

3x + 8 + 3x + 18 + 7x + 9 = 180

add the common numbers

13x + 35 = 180

subtract 35

13x = 145

divide 13

x = 11.2

then plug it back in to m<3

7(11.2) + 9

78.4 + 9

= 87.4°

O salário de um artista é calculado através da função y = 2000 + 500x onde Y representa o valor total em Reais recebido em um mês de trabalho e "x" o número de shows realizados no mês. Qual foi o salário desse artista no mês em que realizou 12 shows?

Answers

Answer:

The artist's salary in the month is 8000.

Step-by-step explanation:

The salary of an artist is given by the function :

y = 2000 + 500x ....(1)

where Y represents the total amount in Reais received in a month of work and "x" the number of shows performed in the month.

We need to find the artist's salary in the month she performed 12 shows.

Put x = 12 in equation (1)

y = 2000 + 500(12)

= 2000 + 6000

= 8000

Hence, the artist's salary in the month is 8000.
