Proportions are corresponding assuming they address a similar relationship. One method for checking whether two proportions are corresponding is to keep in touch with them as divisions and afterward decrease them. Assuming the decreased divisions are something similar, your proportions are relative.
So we use 80% to multiply 20,000
we get 16000
the answer is just 16,000
Answer:
a) 7 + 5i
b) 1 + 24i
a) 34 + i
b) -156 + 12i
Step-by-step explanation:
a) (5 + 8i) + (2 - 3i)
Add real parts ⇒ 5 + 2 = 7
Add imaginary parts ⇒ 8i + -3i = 5i
∴ (5 + 8i) + (2 - 3I) = 7 + 5i
b) (-3 + 12i) + (4 + 12i)
Add real parts ⇒ -3 + 4 = 1
Add imaginary parts ⇒ 12i + 12i = 24i
∴ (-3 + 12i) + (4 + 12I) = 1 + 24i
Products:
a) (5 + 8i)(2 - 3i)
= 10 - 15i + 16i - 24i² ⇒ (i² = -1)
= 10 + i - 24(-1) = 10 + i + 24
= 34 + i
b) (-3 + 12i)(4 + 12i)
= -12 - 36i + 48i + 144i² ⇒ (i² = -1)
= -12 + 12i + 144(-1) = -12 + 12i - 144
= -156 + 12i
