Find the first three iterates of the function f(z) = z2 + c with a value of c = 2 - 3i and an initial value of z0 = 1 + 2i.

Artist 52 [7]

Answer:

Step-by-step explanation:

We have: (I rewrote the function)

$f(z_n)={z_{n-1}} ^2+c$

Given that:

$\displaystyle c=2-3i \text{ and } z_0 = 1 + 2 i$

The first iterate will be:

$\displaystyle \begin{aligned} f(z_1)&=(z_0)^2+c \\ &=(1+2i)^2+(2-3i) \\ &= (1+4i+4i^2)+(2-3i) \\ &=1+4i-4+2-3i \\ &=-1+i \end{aligned}$

The second iterate will be:

$\begin{aligned}f(z_2) &=(z_1)^2+c\\ &=(-1+i)^2+(2-3i) \\&= (1-2i+i^2)+(2-3i) \\&=1-2i-1+2-3i \\&=2-5i \end{aligned}$

And the third iterate will be:

$\begin{aligned} f(z_3)&=(z_2)^2+c\\ &=(2-5i)^2+(2-3i) \\ &=(4-20i+25i^2)+(2-3i) \\ &=4-20i-25+2-3i \\ &=-19-23i \end{aligned}$

Hence, our answer is C.

Greta is opening a savings account. She starts with $100 and plans to add $50 each week. What is the unit rate of change for thi

Semmy [17]

Greta starts with $100 in her savings account

She adds $50 each week

Balance after week 1 = 100 + 50 = 150

Part A

Unit rate of change here is = $\frac{\text{Balance after week 1 - Initial balance}}{\text{Initial balance}} * 100$

⇒ Unit rate of change here is = $\frac{\text{150 - 100}}{\text{100}} * 100$

⇒ Unit rate of change here is = 50%

Part B

Equation to calculate the amount of money Greta will have after any number of weeks = ?

Money after 'x' number of weeks = $\text{Initial Deposit + x * Weekly Deposit}$

⇒ Money after 'x' number of weeks = $\text{100 + x * 50}$

Part C

Money Greta will have after 1 year= ?

In a year there are 52 weeks

So, putting x = 52 in the solution of Part B

⇒ Money after 52 weeks = $\text{100 + 52 * 50}$

⇒ Money after 52 weeks = $\text{100 + 2,600}$

⇒ Money after 52 weeks = 2,700

Answer:

the roots are unequal (distinct)
the roots are irrational
the roots are real

Step-by-step explanation:

A description of the roots of a quadratic can be had by looking at the value of the discriminant: b²-4ac, where a, b, c are the coefficients of the standard-form quadratic.

Here, we have a=3, b=6, c=1 so the discriminant is ...

d = 6² -4(3)(1) = 24

This is a positive integer that is not a perfect square. This value means ...

the roots are unequal (distinct)
the roots are irrational
the roots are real

_____

The interpretation of the discriminant is ...

d > 0, distinct real roots
d = 0, one real root with multiplicity 2
d < 0, complex roots

If d is an integer that is not a perfect square, the roots (or their imaginary part) will be irrational.
