What is i^84? a) -i b) i c) -1 d) 1
mariarad [96]

Answer:

D) 1

Step-by-step explanation:

When you start raising i to certain powers, you begin to notice a pattern.

i^1=i \\\\i^2=-1 \\\\i^3=-i \\\\i^4=1 \\\\i^5=i \\\\ i^6=-1 \\\\ i^7=-i \\\\i^8= 1

This cycle repeats forever. Since 84 is a multiple of 4, i^84 must be 1. Hope this helps!

Given -3(2x+7)=-29-4x prove x=4
Doss [256]

Answer:

x = 4

Step-by-step explanation:

Given

- 3(2x + 7) = - 29 - 4x ← distribute parenthesis on left side

- 6x - 21 = - 29 - 4x ( add 4x to both sides )

- 2x - 21 = - 29 ( add 21 to both sides )

- 2x = - 8 ( divide both sides by - 2 )

x = 4 ← as required
