I think it’s the third option
Answer:
30 J
Step-by-step explanation:
W = mg = 3 N
h = 10 m
Potential Energy = mgh = 3*10 = 30 J
The formula of the distance between two points:

We have the points (-1, -10) and (-12, -3). Substitute:


Answer: d ≈ 13.0
Answer:
2 and remains the same
Step-by-step explanation:
Year GDP
y (billion $)
1985 577
1986 577+ 3.2% of 577 = 577 * 1.032
1987 577* 1.032 + 3.2% of 577 * 1.032 = 577 * (1.032)^2
1988 577 * (1.032)^3
1989 577 * (1.032)^4
.... .... => model GDP = 577 * (1.032)^ (y - 1985)
Then, for GDP = $3.4 trillion = $3400 billion =>
3400 = 577 (1.032)^ (y - 1985)
Divide both sides by 577:
(1.032)^ (y - 1985) = 3400 / 577 = 5.892548
Apply logarith to both sides:
(y - 1985) log (1.032) = log 5.892548
=> y - 1985 = log (5.892548) / log(1.032) = 56.3 years
=> y = 1985 + 56.3 = 2041.3
Answer: 2041
