z = 3+4i , find | z |
-,-

z=3+4i

⟹zˉ=3−4i

∣z∣= √x^2+y^2

∣zˉ∣= √3^2+4^2

∣zˉ∣=√25 = 5

Hence, the modulus of z is 5.

i am sure it will be 90 degrees.

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
