f(i) = i³ - 2i².
i = √-1.
i³ = (√-1)³ = √-1 * √-1 *√-1 = -1*√-1 = -√-1 = -i
i² = (√-1)² = √-1 * √-1 = -1
f(i) = i³ - 2i² = -i - 2(-1) = -i + 2
f(i) = 2 - i

log 27 3=n ⇔ 27^n=3
27=3³
(3³)^n=3 ⇒n=1/3 (3³)¹/³=3³/³=3¹=3
Answer: log 27 3=1/3

log1/4 256=n ⇔(1/4)^n=256
256=2⁸=4⁴
(1/4)^n=4⁴ ⇒n=-4 [ (1/4)⁻⁴=4⁴=256 ]
Answer: log1/4 256=-4

= n0(0.92)^t
Putting n = n0 / 2:
1 / 2 = 0.92^t
t = log(1 / 2) / log(0.92)
= 8.31 yr.

Answer:
The limit as x approaches three from the right of f(x) is:
3
Step-by-step explanation:
We are given a coordinate graph such that:
- The left limit of three approaches to 1 .
( Since A coordinate graph is shown with an upward sloped line crossing the y axis at the origin that ends at the open point (3, 1) )
- The value of the graph at x=3 is: 7
( Since a closed point at (3, 7) )
- Also the right limit at x=3 is: 3
( Since there is a horizontal line starting at the open point (3, 3) )
Hope this helps X

Answer:
0 < t < 1.04 or t ∈ (0, 1.04)
Step-by-step explanation:
Solving in steps:
- 9.8 < 20 – 9.8t < 20
- 9.8 - 20 < -9.8t < 20 - 20 ⇒ subtract 20 from all sides
- -10.2 < -9.8t < 0 ⇒ divide all sides by -9.8, this changes inequality signs to reverse
- 0< t < 10.2/9.8
- 0 < t < 1.04 or t ∈ (0, 1.04)
