To change the base of a logarithm, for example from base a to base c, we use the formula [tex]log_{a} (b)[/tex] = [tex]log_{c} (b)[/tex] / [tex]log_{c} (a)[/tex].

In order to change the base of a logarithm the following basic formula is used,

[tex]log_{a} (b)[/tex] = [tex]log_{c} (b)[/tex] / [tex]log_{c} (a)[/tex]

For example,

If we have to change the base of log₃(81) to base 5,

It will be written as

log₃(81) = log₅(81) / log₅(3)

The change of base rule is able to covert a logarithm in a given base to a logarithm in a new base. The result will be a quotient, which is a fraction, with the new logarithm as both the numerator as well as a denominator.

Step-by-step explanation:

The ratio of 1:

[tex]\frac{1}{6}[/tex] x 60 (hours should be converted to minutes therefore it is 60 mins and

            the denominator seen here is taken by adding the two values in the

             given ratio and since we're still finding 1 you should divide 1 by the

          added denominator and the same applies when finding the ratio 5)

Answer= 10mins

The ratio of 5:

[tex]\frac{5}{6}[/tex] x 60 (refer to the underlined explanation above)

answer= 50mins

so if you want to verify you add the two values you got to see if you got 60 as 60mins in hours was divided in ratio so when you add it will be 60 which means your answer is correct!

Answer: 12:60

Step-by-step explanation: To find the ratio, we must take 1 h and turn it into minutes. So as we know, it's 60 minutes. So next, we shall change the ratio into fraction form (don't worry it's the same basic format)

[tex]\frac{1}{5} = \frac{?}{60}[/tex]

So with that given information, we know that 60 would be our denominator. So, we need to divide both denominators, and then whatever we get from that, multiply that by the given numerator. So, we would do:

60 / 5

= 12

12 * 1

= 12

Therefore we now know that 1/5 = 12/60 as a ratio. I hope this helped :)

y = 8/3x + 100 exists the equation of the line in slope-intercept form.

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line.

A line's slope and y intercept are represented in the slope intercept form as y = mx + b.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) contains

m = y₂-y₁/x₂-x₁

At two of the points the line passes through in the accompanying graph.

Let the two points be (0, 100) and (42, 148)

Let the equation be m = y₂-y₁/x₂-x₁

substitute the values in the above equation, we get

Slope = 148-100/42

= 48/42 = 8/3

To find y intercept, we get

100 = 8/3(0) + b

b = 100

Answer:$917.58.

Step-by-step explanation:

The formula for compound interest is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the initial deposit is $500, the annual interest rate is 4%, the number of times compounded per year is 12 (monthly), and the number of years is 12.

So, we can plug in the values into the formula:

A = $500(1 + 0.04/12)^(12*12) = $500(1.003333333)^(144) = $500(1.835170816) = $917.585

The final amount in her account after 12 years is $917.58

To round to the nearest cent, we can use the following method:

If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.

If the digit in the thousandths place is greater than 5, we round up the hundredths digit.

In this case the digit in the thousandths is 5 so, we have to round up the hundredths digit of $917.58.

So, the final amount in her account after 12 years is $917.59.

Answer: $800.516

Step-by-step explanation:

We use the equation

A = P(1 + )^nt

P = principal

r = rate of interest

t = times

Now let's solve

P = $500

r = 4% = 0.04

t = 12 years

A = $500(1 +[tex]\frac{0.04}{12}[/tex] ) ^12 = $800.516
