No. i*i = -1
2i*3i=-6
now if they meant complex numbers the answer is still no
(2+4i)(2-4i) = 4-8i+8i-16 = -12
Answer:
Average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is <u> 94.43.</u>
Step-by-step explanation:
Here, according to the question:
Number of African American women in elected public office in the United States in the year 1970 = 160
Number of African American women in elected public office in the United States in the year 1993 = 2332
Now, the change in the number of elected women between 1970 & 1993
= Women elected in the year 1993 - Women elected in the year 1970
= 2332 - 160 = 2,172
or, the change in the number of elected women candidates between 1970 & 1993 is 2,172
Now, the difference in the time period is 1993 - 1970 = 23 years
So,![\textrm{ The Average Rate of Change} = \frac{\textrm{The total change in the quantity}}{\textrm{Time Interval}}](https://tex.z-dn.net/?f=%5Ctextrm%7B%20%20The%20Average%20Rate%20of%20Change%7D%20%20%3D%20%5Cfrac%7B%5Ctextrm%7BThe%20total%20change%20in%20the%20quantity%7D%7D%7B%5Ctextrm%7BTime%20Interval%7D%7D)
=![\frac{2,172}{23} = 94.43](https://tex.z-dn.net/?f=%5Cfrac%7B2%2C172%7D%7B23%7D%20%20%3D%2094.43)
Hence, the average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is 94.43.
