If a baseball card appreciates exponentially in value by 50% over 10 years, what is its annual appreciation (growth) rate? Pleas

Natali [406]

Using an exponential function, it is found that it's annual growth rate is of 4%.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

$A(t) = A(0)(1 + r)^t$

In which:

A(0) is the initial value.

r is the growth rate, as a decimal.

In this problem, the card appreciates exponentially in value by 50% over 10 years, hence:

A(10) = 1.5A(0).

Thus:

$A(t) = A(0)(1 + r)^t$

$1.5A(0) = A(0)(1 + r)^{10}$

$(1 + r)^{10} = 1.5$

$\sqrt[10]{(1 + r)^{10}} = \sqrt[10]{1.5}$

1 + r = 1.04.

r = 0.04.

0.04 x 100% = 4%.

It's annual growth rate is of 4%.

Which two kinds of whales have the closest number alive?

tangare [24]

The answer is: Fin whale and Sei whale.

The explanation for this exercise is shown below:

To solve this problem you must use the table given in the figure attached, which shows the numbers of whales alive today. In the column titled "Population" you can see these numbers.

Therefore, when you analize the table, you can conclude that the two kinds of whales that have the closest number alive are: Fin whale, with a population of 55,000 and Sei whale, with a population of 54,000.

In how many ways can the letters of the word POLICEMAN be arranged if the 'word' must begin with L and end with a vowel? & W

Vladimir79 [104]

Answer:

20160 ways

Probability = 0.0556

Step-by-step explanation:

We have 9 different letters, so the total number of words we can make is:

$Total = 9! = 362880\ words$

If we want just the words that begin with L and end with a vowel, we would have the first letter "locked", so we have 8 letters remaining, and it must end with a vowel, so the last "slot" has just 4 possible values (A, E, I or O). Then we would have 4 possible values for the last letter and 7 remaining letters in the middle of the word:

$N = 4 * 7! = 4*7*6*5*4*3*2 = 20160\ words$

The probability is calculated by the division of the number of words we want over the total number of words:

$P = N / Total = 20160 / 362880 = 0.0556$
