Joann invested $43,000 at 6% to be compounded annually. What will be the value of Joann's investment in 2 years? Round your answ

kaheart [24]

Answer:

The total amount after 2 years of Joann's investment at a rate of 6% compounded annually is US$ 48.314.80 (rounded to the nearest cent)

Step-by-step explanation:

1. Let's review the data given to us for answering the question:

Investment amount = US$ 43,000

Duration of the investment = 2 years

Annual interest rate = 6% compounded annually

2. Let's find the future value of this investment after 2 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment = US$ 43,000

number of periods (n) = 2 (2 years compounded annually)

rate (r) = 6% = 0.06

Replacing with the real values, we have:

FV = 43,000 * (1 + 0.06) ²

FV = 43,000 * (1.06) ²

FV = 43,000 * 1.1236

FV = US$ 48.314.80

A student is selecting 5 different geography books, 4 different chemistry books, and one of 7 different science books. In how ma

malfutka [58]

There would be 5184 ways in which each subject books can be selected.

Explanation:

Number of geography books = 5

Number of chemistry books = 4

Number of Science books = 7

Different ways of selecting geography books = 5!

= 5 X 4 X 3 X 2 X 1

= 120

Different ways of selecting chemistry books = 4!

= 4 X 3 X 2 X 1

= 24

Different ways of selecting Science books = 7!

= 7 X 6 X 5 X 4 X 3 X 2 X 1

= 5040

Total different possible ways they can select them = 120 + 24 + 5040

= 5184

The base of an isosceles triangle is 43m The perimeter of the triangle is 4215 cm what is the lenght of either of the remaining

zaharov [31]

Let the length of equal sides be x cm. Perimeter = x cm + x cm + Base = 4 2/15 cm 2x + 4/3 = 62/15 On transposing 4/3 to R.H.S, we obtain 2x = 62/15 - 4/3 2x = 62 - 4 x 5/15 = 62 - 20/15 2x = 42/15 On dividing both sides by 2, we obtain 2x/2 = 42/15 x1/2 x = 7/5 = 1 2/5 Therefore, the length of equal sides is 1 2/5 c m.
