Basically just multiply $2200 By 3% and six years to find your answer. Hope I helped! :D
Answer: 42,500
Explanation:
based on the graph the best answer to go with is 42,500 since it’s past 40,000 and not quite at 45,000. let me know if it’s correct or not, sorry if it won’t be in advance
The code chunk that lets the analyst create the phone_number column is: unite(customers, "phone_number", area_code, phone_num, sep="-"
<h3>What is a data frame?</h3>
A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.
In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.
<h3>The executable code in R Studio.</h3>
In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:
- unite(customers, "phone_number", area_code, phone_num, sep="-"

Iterated elimination of strictly dominated strategies (IESDS) is a common technique that is used to get solutions to games that involve iteratively removing dominated strategies.
<h3>What is a weakly dominated strategy?</h3>
This refers to the type of strategy that delivers an equal or worse outcome than an alternative strategy.
Hence, we can see that in game theory, the use of strategic dominance is used when one strategy is better than another strategy for one player, not withstanding the efforts of the other player.
Therefore, this can be eliminated with the use of iterations to remove the weakly dominated strategies

Answer:
2440.24 J
Explanation:
Moment of inertia, I1 = 5 kg m^2
frequency, f1 = 3 rps
ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s
Moment of inertia, I2 = 2 kg m^2
Let the new frequency is f2.
ω2 = 2 x π x f2
here no external torque is applied, so the angular momentum remains constant.
I1 x ω1 = I2 x ω2
5 x 6 π = 2 x 2 x π x f2
f2 = 7.5 rps
ω2 = 2 x π x 7.5 = 15 π
Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J
Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J
Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J
