A builder makes drainpipes that drop 1cm over a horizontal distance of 30cm to prevent clogs. A certain drainpipe needs to cover
Ann [662]

Answer:

700.39cm

Step-by-step explanation:

For a horizontal distance of 30cm, the drop is 1cm, now we need to get the drop for horizontal distance of 700 cm to maintain the same slope

Using the concept of cross multiplication

30cm=1 cm drop

700 cm=x

30x=700

X=700/30=70/3=23 ⅓

Utilizing pythagoras theorem, the length of pipe will be

L=√(23⅓)²+700²

L=700.38878092417 cm

Rounded off, the length is approximately 700.39 cm

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 .
