Answer:

x = 13

Step-by-step explanation:

one of the rules of logarithm (for all bases, by the way, not just e for ln) is

$a \times ln(b) = ln( {b}^{a} )$

so, we have

ln(3²) = ln(x-4)

=>

3² = x - 4

9 = x - 4

x = 13

2<br> – divide by<br> 45 how can it be simplify 2 divide by 45 <br> What could be the answer.

masya89 [10]

The only "simplify" answer would be in a decimal other than that 2 is not divisible into 45. If you can't fine a whole number that multiplied with the numerator gives you the exact number of the denominator that means that you would have to use decimals or radicals.

Find the sum of the geometric series given a1 = 5, r = 3, n = 12.

diamong [38]

The sum of the geometric series is 1328600

<h3>How to determine the sum?</h3>

The given parameters are:

a1 = 5

r = 3

n = 12

The sum of the terms is:

$S_n = \frac{a(1 - r^n)}{1 - r}$

This gives

$S_n = \frac{5 * (1 - 3^{12})}{1 - 3}$

Evaluate the difference

$S_n = \frac{5 * (1 - 531441)}{-2}$

This gives

$S_n = \frac{5 * - 531440}{-2}$

Evaluate

$S_n = 1328600$

Hence, the sum of the geometric series is 1328600

The deli scale weighs meat and cheese in hundredths of a pound. Sam put 4 10 pound of pepperoni on the deli scale. What weight d

Andreas93 [3]

Answer:

$0.40\ \text{Pounds}$

Step-by-step explanation:

The mass of pepperoni placed on the scale is

$\dfrac{4}{10}\ \text{pounds}$

$=0.4\ \text{Pounds}$

The hundredths place means 2 digits after the decimal point.

Trailing zeros after the decimal point do not change the value of the number.

So, here the scales will show $0.40\ \text{Pounds}$ .
