<span>Initially, the student should estimate how much it will cost to attend the two-year program. Next, she needs to plan how to save part of that amount. Lastly, she must decide on a budget for regular savings deposits.</span>
To calculate total mechanical energy, apply the formula:
total mechanical energy = KE + PE
KE = (1/2)mv^2
=(1/2) x 8 x (20)^2 = 1600 J
For PE, use mgh
g ≈ 10 m/s^2
= 8 x 10 x 85 = 6800 J
Thus, total mechanical energy is 1600 + 6800 = 8400 J
Response:
5 groups of 3
Clarification:
Let x represent the count of four-student groups and y denote the number of five-student groups, resulting in the equation 4x + 5y = 39 (since each group of four has 4 students and each group of five comprises 5 students, yielding a total of 39 students). Additionally, we know that x + y = 9 (indicating the total number of groups is 9).
Next, employ these two equations to isolate and solve for y, eliminating x. There are several methods for achieving this; however, I will utilize subtraction.
4x - 5y = 39
x + y = 9
The second equation
x + y = 9
can be manipulated into
4x + 4y = 36
through multiplying the entire equation by four. This is necessary to ensure x becomes zero. The first equation features 4x.
Therefore, it is now formulated as
4x - 5y = 39 MINUS
4x + 4y = 36
___________
y = 3
To verify the calculation, the remaining 6 four-student groups (totaling 24 students) plus the 3 five-student groups (adding 15 students) sums to 39
