You have your heart set on buying a new car in 2 years. You invest $3,200 at 3.75% interest compounded continuously. How much mo
SCORPION-xisa [38]

<u>Answer:</u>

The available amount for the down payment of car and invested $3,200 at 3.75% interest compounded continuously is 3449.23$

<u>Explanation:</u>

We know final amount is given by  

Where,

A=P \times e^{r t}

A   =   final amount

P   =  initial principal balance = $3200

r    =   interest rate = 3.74%

t    =  number of time periods elapsed = 2 years

Substituting the values in the formula

r=\frac{3.75}{100}=0.0375

A=3200 \times e^{(0.0375 \times 2)}

We know, e = 2.72

So we get A = 3449.23$ which is the available amount for the down payment of car .

AD = 3x + 4 and CD = x + 6, what is the value of x?
lesantik [10]
Your answer would be x = 1.

The rules for a kite shape is that two pairs are of equal length, which means we can say that AD = CD and thus form an equation:

3x + 4 = x + 6
- x
2x + 4 = 6
- 4
2x = 2
÷ 2
x = 1

I hope this helps!
