Answer:
a. 5 + 2i, 13 + 2i, 29 + 2i
Step-by-step explanation:
We'll use the formula f(z) = 2z + (3 - 2i) for each iteration. The output of the first iteration will be come the input of the second iteration, and so on.
So, we start with z0 = 1 + 2i and we plug that into the base equation:
z0 = 1 + 2i ==> f(z) = 2(1 + 2i) + 3 - 2i = 2 + 4i + 3 - 2i = 5 + 2i
z1 = 5 + 2i ==> f(z) = 2(5 + 2i) + 3 - 2i = 10 + 4i + 3 - 2i = 13 + 2i
z2 = 13 + 2i ==> f(z) = 2(13 + 2i) + 3 - 2i = 26 + 4i + 3 - 2i = 29 + 2i
z3 = 29 + 2i
Let's call Tacos t and Enchiladas e.
Lily paid $9 for 2t and 3e
Alex paid $12.50 for 3t and 4e.
Thus the equations would be.
Answer:
210.6 cm
Step-by-step explanation:
Given that a piece of ribbon is cut into two shorter pieces in the ratio 2.8:1.25.
So that means length of the first smaller piece = 2.8x
and length of the second smaller piece = 1.25x
Then difference between their lengths = 2.8x-1.25x = 1.55x
Given that difference is equal to 80.6 centimeters then we get
1.55x=80.6
or x= 80.6/1.55
or x=52
then length of the original piece = 2.8x+1.25x
= 2.8*52+1.25*52
= 145.6+65
= 210.6 cm
To use arithmetic to solve ot
-13 c I think. It is this way because if it went down 15, then you subtract 2-15. 2-2 = 0, and then 0-13= -13 c. Hope this helps
