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 .

tatyana61 [14]

Answer:

- 77x + 42

Step-by-step explanation:

note that (f ○ g)(x) = f(g(x)

Substitute x = g(x) into f(x)

f(g(x))

= f(7x - 4)

= - 11(7x - 4) - 2

= - 77x + 44 - 2

= - 77x + 42

58 yd<br> 73 yd<br> Use 3.14 Instead Of Pie Symbol
defon

Answer:

771096.8 \: yd^{3}

Step-by-step explanation:

If you are trying to find the volume, you would use the formula:

\pi \: r ^{2} (h)

You would plug in the radius (r), which is 58, and then plug in the height, which is 73.

Make sure you remember to use 3.14 and not the pi key if you are using a calculator.

The final answer is 771,096.8 yd^3
