So its pretty much like if your rounding reguraly but the only diffrience is that it had a decimal in it or a dot and you always have to remeber to round the big one first

Otto invests $1,000 at age 20. Otto wants theinvestment to be worth $4,000 by age 30. Ifinterest is compounded continuously, wha

AveGali [126]

$r\approx0.139$

1) Since this is a Continuously Compounded operation in a 10 yrs period, then we can write out the following equation:

$\begin{gathered} A=Pe^{rt} \\ \end{gathered}$

2) Plugging into the equation the given data and since Otto is 20 yrs old and he plans to get $4,000 in ten years, we can write out:

$\begin{gathered} 4000=1000e^{\mleft\{10r\mright\}} \\ \frac{4000}{1000}=\frac{1000e^{10r}}{1000} \\ 4=e^{10r} \\ \ln (4)=\ln (e)^{10r} \\ 10r=\ln (4) \\ r=\frac{\ln (4)}{10} \\ r=0.1386 \end{gathered}$

3) Thus the rate Otto needs is

$r=0.1386\approx0.139$

Note that since the 0.1386 the six here is greater than 5 then we can round up to the next thousandth, in this case: 0.139. For the 0.1386 is closer to 0.139 (0.004) than to 0.138 (0.006).

Or 13.9%

Write two decimals one repeating and one terminating with the values between 0 and 1

weqwewe [10]

A repeating decimal is one that essentially goes on forever. A terminating decimal is one that has an end, therefore a definite value.

The fraction 1/3 is a repeating decimal, because when you divide 1 by 3, you get .333333 (to infinity). To show that something is repeating, draw a bar (or line) above the number that is repeating, in this case, 3.

The fraction 1/4 is a terminating decimal. Like the one above, when you divide 1 by 4, you get a fraction. In this case, it is .25, which does not repeat.

The fractions are there just to show you how you could get to either, but your terminating decimal is .25, and your repeating decimal is .3 (but with a line over the 3 if possible).

State the Postulate or Theorem that can be used to say that the triangles are congruent:

Snezhnost [94]

The congruence theorems or postulates that proves the following set of triangles are congruent are:

a. SAS congruence postulate

b. SSS congruence postulate

c. SAS congruence postulate

d. SAS congruence postulate

<h3>Triangle Congruence Postulates or Theorems</h3>

Two triangles having two pairs of congruent angles and a pair of included sides are congruent by the SAS congruence postulate.

Two triangles having three pairs of congruent sides are congruent by the SSS congruence postulate.

Two triangles having two pairs of congruent sides and a pair of included angles are congruent by the SAS congruence postulate.

Two triangles having two pairs of congruent angles and a non-included side are congruent by the SAS congruence postulate.

Therefore, the congruence theorems or postulates that proves the following set of triangles are congruent are:

a. SAS congruence postulate

b. SSS congruence postulate

c. SAS congruence postulate

d. SAS congruence postulate
