Rochelle deposits $5,000 in an IRA. What will be the value of her investment in 25 years if the investment is earning 8% per yea
Iteru [2.4K]

Answer:

\$36,945.28  

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=25\ years\\ P=\$5,000\\ r=8\%=8/100=0.08

substitute the values in the formula

A=5,000(e)^{0.08*25}  

A=5,000(e)^{2}  

A=\$36,945.28

Two square rooms have a total floor area of 89m2. One room is 3m longer each way than the other. Find the dimensions of the two
Rudiy27

Answer:

A

Step-by-step explanation:

Let the smaller room have an area of x^2

Let the larger room have an area of (x + 3)^2

(x+3) ^2 + x^2 = 89               Be careful not to make it 89^2.

x^2 + 6x + 9 + x^2 = 89        Expand the binomial squared

2x^2 + 6x + 9 - 89 = 0          Subtract 89 from both sides

2x^2 + 6x + 9 - 89 = 0          Combine

2x^2 + 6x - 90=0                  Divide by 2

x^2 + 3x - 45 = 0         This factors.

(x + 9)(x- 5) = 0

X + 9 gives nothing useful

x - 5 = 0

x = 5

x + 3 = 5+3 = 8

So the answer is A
