For the complex number := a + bi, if a=0, what can you conclude about z? O z is a complex number graphed in the first quadrant.
O z is a real number graphed along the real axis.
O z is a complex number graphed in the fourth quadrant.
O z is an imaginary number graphed along the imaginary axis.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

step-by-step explanation:

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
