Answer:
Step-by-step explanation:
-i= -i
-i^2= 1
-i^3= -i * 1 = -i
-i^4= 1 * (-1) = -1
-i^5= -i
-i^6= 1
Answer:
Step-by-step explanation:
<u>Given trinomial:</u>
<u>Complete square:</u>
- z² - 2*2.5*z + 2.5² + c - 2.5² =
- (x - 2.5)² + c - 6.25
<u>The value of c:</u>
Step-by-step explanation:
Lets consider the unknown number as x
according to the question,
6-x= 5(x+2)
6-x= 5x+10
-x-5x=10-6
-6x=4
x=4/-6= 2/-3
x= -2/3

Answer:
a = 144
b = 67
Step-by-step explanation:
Where a transversal meets parallel lines, consecutive interior angles are supplementary.
<h3>Angles</h3>
a° +36° = 180° . . . . . . consecutive angles are supplementary
a = 144 . . . . . . . . . . divide by ° and subtract 36
b° +113° = 180° . . . . . . consecutive angles are supplementary
b = 67 . . . . . . . . . . divide by ° and subtract 113
