How much would $600 be worth after 10 years, if it were invested at 4%
sesenic [268]

The worth after 10 years if it were invested at 4%  interest compounded continuously is $ 895.094

<h3><u>Solution:</u></h3>

Given that $ 600 invested at 4 % interest compounded continously for 10 years

To find: total amount after 10 years

<em><u>The compound interest formula for compounded continously is given as:</u></em>

A = p e^{rt}

Where "p" is the principal

"r" is the rate of interest

"t" is the number of years

Here in this problem, p = 600

r = 4 \% = \frac{4}{100} = 0.04

t = 10 years

Substituting the values in formula we get,

A = 600 e^{0.04 \times 10}\\\\A = 600 e^{0.4}\\\\A = 600 \times 1.49182469764\\\\A = 895.094

Thus the worth after 10 years is $ 895.094

RSB [31]

Answer: y = 800

Step-by-step explanation:

3(y+200) = 3000

y+200 = 1000 (dividing 3 from both sides)

y = 800

Answer:

the SSS similarity theorem

Step-by-step explanation:

⇒ It cannot be the SAA similarity theorem as they only share a single common angle

⇒ It cannot be the HL similarity theorem, as the sides are not equal

⇒ It must be the SSS triangles

===========================================================

<h3>What is the SSS similarity theorem?</h3>

It states that :

If the lengths of the corresponding sides of two triangles are proportional, then the two triangles are similar.

============================================================

Let's take the sides in proportion :

⇒ 15/5 = 3 (Hypotenuses)

⇒ 6+3/3 = 9/3 = 3 (Heights)

⇒ 8+4/4 = 12/4 = 3 (Bases)

As the sides are in proportion, the triangles are similar by the SSS similarity theorem.
