F(z) = 2z - (3+i)

1) second interate for z0 = i

first iterate = f(z0) = f(i) = 2i - 3 - i = i - 3 = z1
second iterate = f(z1) = f(i-3) = 2(i-3) - 3 - i = 2i - 6 - 3 - i = i - 9

2) third iterate for z0= 3 - i

first iterate = f(z0) = f(3 - i) = 2(3-i) - (3+i) = 6 -2i -3 - i =3 - 3i = z1
second iterate = f(z1) = f(3 -3i) = 2(3-3i) - (3+i) = 6 - 6i -3 -i = 3 - 7i = z2
third iterate = f(z2) = f(3 - 7i) = 2 (3-7i) - (3+i) = 6 - 14i - 3 - i = 3 -15i = z3.

3) first iterate for z0=0.5+i

first iterate = f(z0) = f(0.5 +i) = 2(0.5+i) - (3+i) = 1 +2i - 3 - i = - 2 + i = z1

4) third iterate for z0=-2-5i

first iterate = f(z0) = 2(- 2 - 5i) - (3 + i) = - 4 - 10i - 3 - i = -7 - 11i = z1
second iterate = f(z1) = 2( - 7 - 11i) - (3+i) = -14 - 22i - 3 - i = -17 -23i = z2
third iterate = f(z2) = 2(-17-23i) -(3+i) = -34 - 46i -3 - i = -37 - 47i = z3

there are 8 uniforms at a fire station. Their total weight is 538 pounds. about how many pounds does each uniform Weigh? would y
earnstyle [38]

If 8= 538 Ib. then take the (538) and divide that by 8. <---- 8 for the 8 uniforms.

Your math should look like this: 538/8= about 67 pounds.

Then do 67*8= 536. (You started at 532 Ib.) this is just 2 pounds off*

So, your answer should be *67* pounds.

*Use paper and a pencil! Sometimes doing mental math can be challenging with a problem like this. So use paper and a pencil, checking your answer wont hurt either!*

Gabriella drives her car 320 miles and averages a certain speed. If the average speed has been 6 miles less she could have trave
arsen [322]

Answer:

Her average speed is 48 miles per hour.

Step-by-step explanation:

We solve this question using a system of equations.

The speed equation is:

s = \frac{d}{t}

In which s is the speed, d is the distance, and t is the time.

Gabriella drives her car 320 miles and averages a certain speed.

So d = 320

Then

s = \frac{320}{t}

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.

So, which s - 6, d = 280.

s - 6 = \frac{280}{t}

From the first equation:

s = \frac{320}{t}

st = 320

t = \frac{320}{s}

Replacing:

s - 6 = \frac{280}{t}

s - 6 = \frac{280}{\frac{320}{s}}

320(s - 6) = 280s

320s - 1920 = 280s

40s = 1920

s = \frac{1920}{40}

s = 48

Her average speed is 48 miles per hour.
