Find the third, fourth, and fifth terms of the sequence defined by
a1 = 1, a2 = 3,
and
an = (−1)nan − 1 + an − 2
for
n ≥ 3.
The third term (a3) of the sequence is -8, the fourth term (a4) is 35, and the fifth term (a5) is -183. These values are obtained by applying the given formula recursively and substituting the previous terms accordingly. The calculations follow a specific pattern and are derived using the provided formula.
The sequence is defined by the following formula:
a1 = 1, a2 = 3,
and
an = (-1)nan - 1 + an - 2 for n ≥ 3.
To find the third term (a3), we substitute n = 3 into the formula:
a3 = (-1)(3)(a3 - 1) + a3 - 2.
Next, we simplify the equation:
a3 = -3(a2) + a1.
Since we know a1 = 1 and a2 = 3, we substitute these values into the equation:
a3 = -3(3) + 1.
Simplifying further:
a3 = -9 + 1.
Therefore, the third term (a3) is equal to -8.
To find the fourth term (a4), we substitute n = 4 into the formula:
a4 = (-1)(4)(a4 - 1) + a4 - 2.
Simplifying the equation:
a4 = -4(a3) + a2.
Since we know a2 = 3 and a3 = -8, we substitute these values into the equation:
a4 = -4(-8) + 3.
Simplifying further:
a4 = 32 + 3.
Therefore, the fourth term (a4) is equal to 35.
To find the fifth term (a5), we substitute n = 5 into the formula:
a5 = (-1)(5)(a5 - 1) + a5 - 2.
Simplifying the equation:
a5 = -5(a4) + a3.
Since we know a4 = 35 and a3 = -8, we substitute these values into the equation:
a5 = -5(35) + (-8).
Simplifying further:
a5 = -175 - 8.
Therefore, the fifth term (a5) is equal to -183.
In summary, the third term (a3) is -8, the fourth term (a4) is 35, and the fifth term (a5) is -183.

Plug in for x = 3 and y = -6
I'll start with x to make it easier.
Plugging in x =3
[tex]\sqrt{x^4}[/tex]
Means that first we find x^4, and take the square root of that result.
1. Find x^4
x = 3
3^4 = 3 * 3 * 3 *3 = 81
2. Take the square root of x^4
Square root of 81 = 9
So [tex]\sqrt{x^4}[/tex] = 9
Plugging in y = -6
Let's move onto plugging in y, which appears in the expression as y²
y = -6
so y² = -6 * -6 = 36
Putting this together into the expression
[tex]\sqrt{x^4}[/tex] - y²

A fruit vendor sold 2/5 of his grapefruits on Friday and 1/2 of the remainder on Saturday. He had 60 grapefruits left. a) What fraction of grapefruits did he sell on Saturday? b) How many grapefruits did he have at first? c) How many did he sell on Friday?
a) The fruit vendor sold 3/10 of the grapefruits on Saturday, b) The vendor had 100 grapefruits at first, and c) 40 grapefruits were sold on Friday.
a) On Saturday, the fruit vendor sold 1/2 of the remaining grapefruits. Since 2/5 of the grapefruits were sold on Friday, there are 3/5 of the original amount left. Therefore, on Saturday, the vendor sold (1/2) x (3/5) = 3/10 of the grapefruits.
b) To find the original number of grapefruits, we need to calculate the total amount remaining after Friday's sales. Since there were 60 grapefruits left after Saturday's sales and 3/5 of the original amount remained, we can set up the equation (3/5) [tex]\times[/tex]x = 60, where x represents the original number of grapefruits.
Solving for x, we have x = (60 x 5) / 3 = 100 grapefruits. Therefore, the fruit vendor had 100 grapefruits at first.
c) To find the number of grapefruits sold on Friday, we subtract the amount remaining after Friday's sales from the original number. 2/5 of the grapefruits were sold on Friday, so the number sold is (2/5) x 100 = 40 grapefruits.
In summary, a) the fruit vendor sold 3/10 of the grapefruits on Saturday, b) the vendor had 100 grapefruits at first, and c) 40 grapefruits were sold on Friday.

A. 0.00430
B. 0.00467
C. 0.000358
D. 0.0512
Answer:
B. 0.00467
Step-by-step explanation:
This is a binomial probability problem. The probability of fewer than three adults watching prime-time TV live is the sum of the probabilities of 0, 1, and 2 adults watching prime-time TV live.
Let X be the number of adults watching prime-time TV live. The probability mass function of X is given by:
P(X=k)=(kn)p^k(1−p)^n−k

A minibus was purchased for R241 000. The rate of depreciation 22% p.a. on a reducing balance basis. The cost of a new minibus inflates at a rate of 15% p.a.
Calculate the replacement cost of the minibus in 4 years’ time if the old minibus is used as a trade-in.
A fixed amount is deposited into a sinking fund at the end of each month for the purchase of a new minibus in 4 years’ time. Calculate the required monthly payment if interest is earned at the rate of 8,6% p.a. compounded monthly, and the first payment is only made three months after the original bus was purchased.
Replacement cost of the minibus in 4 years' time, considering the trade-in of the old minibus, is R9,411.70.
1. Calculate the depreciation of the minibus over 4 years:
Depreciation = Original cost * (1 - Rate of depreciation) Number of years
Depreciation = R241,000 * (1 - [tex]0.22)^4[/tex]
Depreciation = R241,000 * [tex]0.78^4[/tex]
Depreciation ≈ R91,073.17
2. Calculate the remaining value of the minibus after 4 years:
Remaining value = Original cost - Depreciation
Remaining value = R241,000 - R91,073.17
Remaining value ≈ R149,926.83
3. Calculate the inflated cost of a new minibus in 4 years:
Inflated cost = Original cost * (1 + Rate of inflation) Number of years
Inflated cost = R241,000 * (1 + [tex]0.15)^4[/tex]
Inflated cost = R241,000 * [tex]1.15^4[/tex]
Inflated cost ≈ R421,731.04
4. Calculate the replacement cost by subtracting the remaining value and adding the inflated cost:
Replacement cost = Remaining value + Inflated cost
Replacement cost = R149,926.83 + R421,731.04
Replacement cost ≈ R571,657.87
5. Calculate the trade-in value by subtracting the depreciation from the replacement cost:
Trade-in value = Replacement cost - Depreciation
Trade-in value = R571,657.87 - R91,073.17
Trade-in value ≈ R480,584.70
6. Therefore, the replacement cost of the minibus in 4 years' time, considering the trade-in, is approximately R480,584.70.
For the second question:
1. Determine the number of months until the first payment is made:
Number of months = 4 years * 12 months/year - 3 months
Number of months = 48 months - 3 months
Number of months = 45 months
2. Use the formula for the future value of a series of payments to calculate the required monthly payment:
Monthly payment = (Future value * Interest rate) / ((1 + Interest rate) Number of periods - 1)
Monthly payment = (Replacement cost * Monthly interest rate) / ((1 + Monthly interest rate) Number of months - 1)
Monthly payment = (R480,584.70 * 0.086/12) / ((1 + [tex]0.086/12)^4^5[/tex] - 1)
Monthly payment ≈ R9,411.70
3. Therefore, the required monthly payment to the sinking fund for the purchase of a new minibus in 4 years' time, with the first payment made three months after the original bus was purchased, is approximately R9,411.70.

a. What is the initial velocity of the marble?
b. How fast is the marble rolling at time 4 seconds?
c. At what time is the velocity 50 cm/s?
d. How fast is the marble rolling when it is 90 cm from its starting point?
e. Find and interpret lim s(t) t-> infinity and lim v(t) lim t-> infinity. Do you think this model is valid for large values of t?
Explain.
a. The initial velocity of the marble is 0 cm/s.
b. The marble is rolling at a speed of 80 cm/s at 4 seconds.
c. The velocity is 50 cm/s at approximately t = 2√2 - 1 seconds.
d. The marble is rolling at a speed of 90 cm/s when it is 90 cm from its starting point at t = 9 seconds.
e. lim s(t) as t approaches infinity is 100 cm and lim v(t) as t approaches infinity is 0 cm/s; the model may not be valid for large values of t as it assumes the marble is rolling up an inclined plane without considering other factors such as friction.
a. To find the initial velocity of the marble, we need to calculate the limit of the function s(t) as t approaches 0:
lim (t->0) s(t) = lim (t->0) (100t / (t + 1))
By substituting 0 into the expression, we get:
lim (t->0) (0 / (0 + 1)) = 0 / 1 = 0.
Therefore, the initial velocity of the marble is 0 cm/s.
b. To find the speed of the marble at time 4 seconds, we substitute t = 4 into the expression for s(t):
s(4) = 100(4) / (4 + 1) = 400 / 5 = 80 cm/s
The marble is rolling at a speed of 80 cm/s at 4 seconds.
c. To find the time at which the velocity is 50 cm/s, we set s'(t) (the derivative of s(t)) equal to 50 and solve for t:
s'(t) = 50
[tex](100 / (t + 1))^2 = 50[/tex]
100 / (t + 1) = ±√50
100 = ±√50(t + 1)
±√50(t + 1) = 100
t + 1 = 100 / ±√50
t + 1 = ±2√2
Since time cannot be negative, we take t + 1 = 2√2:
t = 2√2 - 1
The velocity is 50 cm/s at approximately t = 2√2 - 1 seconds.
d. To find the speed of the marble when it is 90 cm from its starting point, we need to solve the equation s(t) = 90 for t:
100t / (t + 1) = 90
100t = 90(t + 1)
100t = 90t + 90
10t = 90
t = 9
The marble is rolling at a speed of 90 cm/s when it is 90 cm from its starting point, which occurs at t = 9 seconds.
e. The limit of s(t) as t approaches infinity (lim s(t) as t->∞) is calculated by considering the dominant term in the numerator and denominator:
lim (t->∞) (100t / (t + 1))
≈ lim (t->∞) (100t / t)
= lim (t->∞) 100
= 100
Therefore, lim s(t) as t approaches infinity is 100 cm.
Similarly, the limit of v(t) (velocity) as t approaches infinity (lim v(t) as t->∞) can be found by taking the derivative of s(t) and evaluating the limit:
[tex]v(t) = s'(t) = 100 / (t + 1)^2[/tex]
lim (t->∞) v(t) = lim (t->∞) (100 / [tex](t + 1)^2)[/tex]
≈ lim (t->∞)[tex](100 / t^2)[/tex]
= lim (t->∞) [tex](100 / t^2)[/tex]
= 0.
The limit of v(t) as t approaches infinity is 0 cm/s.
As for the validity of the model for large values of t, it is important to note that the given model assumes that the marble is rolling up an inclined plane.
However, without further information about the nature of the inclined plane (e.g., its slope, frictional forces), it is difficult to determine the accuracy.
