Answer:
A. (2i)(8) = d. 16i
B. 16i³ = b. -16i
C. (2i)⁴ = a. 16
D. (2i)(8i) = c. -16
Step-by-step explanation:
A. Multiply 2i by 8 to get 16i, which corresponds to d.
B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.
C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.
D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.
The unknowns should be 1 or 3. we don't know the total number of children and parents in the room, but we have a clue which 25, so if we were to subtract 9 from 25 we would get 16. i would recommend number 1
63= 60 then... 60/6 = 10
108=100 then... 100/ 8= 12. 5
60 sec in 1 min so ...
12.5 * 6 = 75
10*6= 60
75 - 60= 15 feet apart.
I don't know what the expanded form is but the word form is two million nine hundred forty seven.
7 females to 17 males
I divided both sides by 3
