For Review: Planning Ahead and Contracts Quick Check... these are the answers...
1) B. Yes, you want to begin saving at least 25 years before you plan to retire
2) D. all of the above
3) $2,341.27 per month realized income
4) Your housing and fixed expenses are $702.38 per month do you want to have a four month emergency fund and save it over a nine month period of time how much do you need to save per month?
Answer #4) $312.17 /month
Step-by-step explanation:
702.38 * 4 = 2,809.52 How much you will need to save for 4 months worth or expenses.
Now divide by 9 because that is how many months you will take to save up...
2,809.52 / 9 = 312.17
Answer) $312.17 per month, for 9 months to save 4 months worth or expenses.
Answer:
A) (1 s, 2.3 s)
B) (-4 m/s², 3.8 m/s²)
Step-by-step explanation:
The car's position which is the distance is given by the equation;
s(t) = t³ - 5t² + 7t
A) Velocity is the first derivative of the distance. Thus;
v(t) = ds/dt = 3t² - 10t + 7
At v = 0, we have;
3t² - 10t + 7 = 0
Using quadratic formula, we have;
t = 1 and t = 2.3
Thus, time at velocity of 0 is t = (1 s, 2.3 s)
B) acceleration is the derivative of the velocity. Thus;
a(t) = dV/dt = 6t - 10
At velocity of 0, we got t = 1 and t = 2.3
Thus;
a(1) = 6(1) - 10 = -4 m/s²
a(2.3) = 6(2.3) - 10 = 3.8 m/s
Thus, a(t) at v = 0 gives; (-4 m/s², 3.8 m/s²)
