Jack inherited a perpetuity-due, with annual payments of 15,000. He immediately exchanged the perpetuity for a 25-year annuity-d

ue having the same present value. The annuity-due has annual payments of X. All the present values are based on an annual effective interest rate of 10% for the first 10 years and 8% thereafter. Calculate X.

Answer:

X=17,384.37

Step-by-step explanation:

The present value of the perpetuity can be calculated by discounted for the different interest rates:

PV_{perpetuity}=[\frac{1}{0.1}+\frac{(\frac{1}{0.08}-\frac{1}{0.1})}{1.1^{10}}]\times 15,000+15000\\\\\\=164,457.87+15,000=179,457.87

#Now, we use the annuity-due present value factor to get the present values of the annuity payments, let X be the annual annuity payments;

X[\ddot a_{10}_|_{0.10}+\frac{\ddot a_{15}|_{0.08}}{1.10^{10}}]=179,457.87\\\\\\X[6.759+\frac{9.244}{1.1^{10}}]=179457.87\\\\\\X=17384.37

Hence, the value of X is 17,384.37

PlEASE HELP ME PEOPLE HUMPTH OK ILL SAY IT PEOPLE WANT MONEY TO ANSWER PROBLEMS HERE If the mean of six nu m b e rs is 48, does
SpyIntel [72]

Answer:

No, none of the number need to be 48 for the mean to be 48. To get a mean, you add up all the number and divide it by the amount of numbers.

Example:

the mean of 10, 79, 42, 88, 19, and 50 is 48, but the actual number 48 was not part of the set.

10 + 79 + 42 + 88 + 19 + 50 = 288

288 ÷ 6 = 48

ASAP HELP FOR NUMBER 12, Thank you so much!!! :)
qaws [65]
12a)
5x + 45 + 3x - 25 = 180
8x + 20 = 180
8x = 160
  x = 20

12b)
2x - 5 = 2(20) - 5 = 40 - 5 = 35
3x - 25 = 3(20) - 25 = 60 - 25 = 35

y = 180 - (35+35)
y = 180 - 70
y = 110

Question 1
Because the period is 2π, and the amplitude is 1obtain
f(x) = sin(x)
Because the horizontal shift is π, obtain
f(x) = sin(x - π)
Because the vertical shift is -4, obtain
f(x) = sin(x - π) - 4

Answer: 1. f(x) = sin(x - π) - 4

Question 2
The radius is 36/2 = 18 in.
1 revolution (360°) is the circumference, which is
2π(18) = 36π in
When the revolution is 62°, the distance traveled is
(62/360)*(36π) = (31/5)π in

Answer: 3. (31π)/5

Question 3.
Consider f(x) = 3cos(2x-π) - 1
f(0) = 3cos(-π) - 1 = -4
f(π/2) = 3cos(0) - 1 = 2
Rate of change = (2+4)/(π/2) = 12/π

From the graph, the rate of change of g(x)  is
3/(π/2) = 6/π

Consider h(x) = sin(x) - 4
h(0) = 0 - 4 = -4
h(π/2) = 1 - 4 = -3
Rate of change = (-3+4)/(π/2) = 2/π
Therefore h(x) has the smallest rate of change

Answer: h(x)
