If $1000 is invested at 8% interest, compounded annually, then after n years the investment is worthan = 1000(1.08)ndollars.(a)

Luba_88 [7]

Answer:

Diverge

Step-by-step explanation:

(a)

1st year: $1000 * 1.08^1 = \$1080$

2nd year: $1000 * 1.08^2 = \$1166.4$

3rd year: $1000 * 1.08^3 = \$1259.71$

4th year: $1000 * 1.08^4 = \$1360.49$

5th year: $1000 * 1.08^5 = \$1469.33$

(b) The sequence is divergent, because if we take the derivative of the function with respect to n year:

$(1000*1.08^n)^{'} = 1000ln(n)*1.08^n$

This is a positive, meaning the slope of the function is positive. If we take the second derivative using product rule

$(1000ln(n)*1.08^n)^{'} = 1000\frac{ln(n)}{n}1.08^n$

This is also positive when n > 0. Therefore, the slope is positive and increasing. This means the sequence diverges.

Uncle Tan harvested 24.9 tons of pears. He found that 22.41 tons of the pears were rotten pears. What percent of the harvested p

Serhud [2]

Hi there! The answer is 10%.
To find our answer we use the following formula:
$part / total \times 100 \%$

The percentage of rotten pears is
$\frac{22.41}{24.9} \times 100\% = 90\%$

Therefore
$100\% - 90\% = 10\%$
Of the pears are good pears.
