Answer:

The solutions are the following:

  • z=2(cos(π6)+isin(π6))=√3+12i

  • z=2(cos(2π3)+isin(2π3))=−1+i√3

  • z=2(cos(7π6)+isin(7π6))=−√3−12i

  • z=2(cos(5π3)+isin(5π3))=1−i√3

Which of the following functions has a horizontal asymptote at y = 2?
Leona [35]

Answer: The first graph

Step-by-step explanation:

An asymptote is an imaginary line that the function is approaching but never reaching. y=2 is a horizontal line. Therefore by looking at the graphs, the first graph shows the two functions never approaching 2, but gets very close to it. Therefore it is the first graph.

20 POINTS!!! HELP ME!!!! Use the linear combination method to solve the system of equations. Explain each step of your solution.
madreJ [45]

The solution of the system of equations is (-3 , -2)

Step-by-step explanation:

Steps for Using Linear Combinations Method)

  • Arrange the equations with like terms in columns
  • Analyze the coefficients of x or y
  • Add the equations and solve for the remaining variable
  • Substitute the value into either equation and solve

∵ 3 x - 8 y = 7 ⇒ (1)

∵ x + 2 y = -7 ⇒ (2)

- Multiply equation (2) by 4 to make the coefficients of y are equal in

 magnitude and different in sign

∴ 4 x + 8 y = -28 ⇒ (3)

Add equations (1) and (3)

∵ 3 x - 8 y = 7 ⇒ (1)

∵ 4 x + 8 y = -28 ⇒ (3)

∴ 7 x = -21

- Divide both sides by 7

∴ x = -3

Substitute the value of x in equation (2) to find y

∵ x + 2 y = -7 ⇒ (2)

∵ x = -3

∴ -3 + 2 y = -7

- Add 3 to both sides

∴ 2 y = -4

- Divide both sides by 2

∴ y = -2

The solution of the system of equations is (-3 , -2)

A tile pattern has five tiles in Figure 0 and adds seven tiles in each new figure. Write a linear equation that represents this
Olenka [21]

The linear equation that represents the <u>number of tiles in figure x</u> is given by:

y = 7x + 5

---------------------

A linear equation has the format:

y = mx + b

In which:

  • m is the slope, that is, the rate of change.
  • b is the y-intercept, that is, the value of y when x = 0.

---------------------

  • Figure 0 has 5 tiles, that is, when x = 0, y = 5, thus b = 5
  • Seven new tiles in each figure, that is, a rate of change of 7, thus m = 7

The number of tiles in figure x is given by:

y = 7x + 5
