A) Patty Stacey deposits $2600 at the end of each of 5 years in an IRA. If she leaves the money that has accumulated in the IRA
ruslelena [56]

Answer:

From the question, Stacey deposits $2600 six times over a thirty year period since she makes the deposit every five years. Her amount accures by the formular. A = P(1+r/n)^nt. Where her principal P = $2,600. Rate, r =6% =0.06. Time = 30 years and the period of compounding per unit time, n = 6 years. So we have A =2, 600(1+(0.06/6))^(6*30) = 2, 600 (1 + 0.01)^(180) = 2600* 5.9958 = $15, 587. To the nearest cent we have $15, 590.

krok68 [10]

Answer:

a = 73.84, b = -23.64, c = 83.97, d = 21.73

Step-by-step explanation:

1880:

The predicted value is:

f(80) = 1.363\cdot (80) - 35.2

f(80) = 73.84

The residual value is:

\Delta f = 50.2 - 73.84

\Delta f = -23.64

1920:

The predicted value is:

f(120) = 7.8 \cdot 1.02^{120}

f(120) = 83.97

The residual value is:

\Delta f = 105.7 - 83.97

\Delta f = 21.73
