The logarithm and exponential functions are inverse of each other. The exponential function raises a number to a power and the logarithm gives the power that the number has to be raised to in order to equal a given value. In other words, the exponential function expresses exponential growth, while the logarithm expresses exponential decay.
For example, if y = 2^x, then x = log2(y). This logarithmic relationship is useful in solving exponential problems and understanding exponential dynamics.
In exponential dynamics, logarithms are used to study and model changes that occur at exponential rates, such as population growth or decay, interest rate calculations, and many other real-world applications. The logarithmic relationship helps to simplify the exponential equations and make them easier to work with.
In summary, the logarithm and exponential functions are important in understanding exponential dynamics because the logarithmic relationship helps to simplify exponential problems and make them easier to solve.

Thrice a number when increased by 6 gives 24
Answer:6
Step-by-step explanation:
Let the number be x.
Now, 3x+6=24
3x=24-6
3x=18
x=18/3
x=6
Answer:
6
Step-by-step explanation:
We can work the problem backwards
Since something gives 24 that means it equals 24
= 24
Something increased by 6, so something added by 6
Something + 6 = 24
Making something = x
x + 6 = 24
If we subtract 6 from both sides
x = 18
Trice a number, so divide this number by 3
x = 6
Trice of 6 is 18... 18 increased by 6 gives 24

Eric throws a biased coin 10 times and gets tails 3 times.
Sue throws the same coin 50 times and gets tails 20 times.
Audi is going to throw the coin once.
Use Erics and Sues results to work out an estimate for the probability that Aadi will get tails. write your fraction in the form a/b.
Answer:
Below
Step-by-step explanation:
Out of 50 + 10 = 60 tries, 3 + 20 = 23 times were tails
23/60 chance of tails
The estimate of the probability that Audi gets tails is given as follows:
p = 23/60.
How to calculate a probability?A probability is calculated via the division of the number of desired outcomes by the number of total outcomes.
Hence the probability of each person getting tails when they throw a biased coin is given as follows:
Eric: 3/10.Sue: 20/50 = 2/5.The total number of throws is given as follows:
50 + 10 = 60.
The number of tails is given as follows:
3 + 20 = 23.
Hence the probability for Audi is given as follows:

How do you find the time in math?Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present, and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.The equation for calculating time is [Time = Distance ÷ Speed].Seconds, minutes, hours, days, weeks, months, and years are the fundamental units of time. To determine the time of day, we use seconds, minutes, and hours; to determine the date, we use days, months, and years. The smallest units of time are seconds, minutes, and hours, while the larger ones are days, months, and years.Given data :
Today, he studies 15 minutes math and 75 minutes science and from now on, 50 minutes math and 30 minutes science. So if he studies for 1 day total time for math and science will be:
Math = 15 + 50 = 65
Science = 75 + 30 = 105
2nd day:
Math = 65 + 50 = 115
Science = 105 + 30 = 135
3rd day:
Math = 115 + 50 = 165
Science = 135 + 30 = 165
So, after three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.

Estimate the indicated probability by using the normal distribution as an approximation to the binomial distribution. Estimate p(6) for n = 18 and p = 0. 3.
By applying normal approximation to the binomial concept, it can be concluded that the indicated probability is 0.62134
Normal approximation to the binomial is a method of approximating the probabilities associated with the binomial distribution using the normal distribution.
μ = n.p
σ = √np(1-p)
where μ is the mean, n is the number of trials, p is the success probability and σ is the standard deviation.
Now we have:
x = 6
n = 18
p = 0.3
Thus we can calculate the mean:
μ = np
= 18 * 0.3
= 5.4
Now we calculate the standard deviation
σ = √μ (1-p)
= √ 5.4 (1 - 0.3)
= √ 5.4 * 0.7
= √ 3.78
= 1.944
Then we can find the z-score using the mean and standard deviation found in the previous step:
z-score = (x – μ) / σ
= (6 - 5.4) / 1.944
= 0.6 / 1.944
= 0.309
And finally, we can obtain from the z table that P(6) = P(x<0.309) = 0.62134

off 4 years early?
O
A. $312,423. 90
O
B. $37,842. 06
O
O
c. $274,581. 84
D. $316,825. 20
Option A is the correct Answer. The total cost of his loan if he paid it off 4 years early is 312,423.90
We have given:
The principal amount which is 30,000
Time which is 30 year
The rate which is 5.5%
And since, we have to find 4 years early so, the time would be: 20-4=16 years.
And since, we have to find for 12 months
Hence, n=12
We have the formula to calculate compound interest:
[tex]A=P(1+\frac{r}{n})^n^t[/tex]
Where
A=compound interest
P= Orginal amount deposited.
r= rate
n=times its compounds per year monthly
t= years.
P=155000, r=5.5, t=16
On substituting the values we get:
[tex]A=155000(1+\frac{0.055}{12})^1^2^*^1^6\\\\A=155000(1+\frac{0.055}{12})^1^9^6\\\\A=155000(14884.0754)\\\\A=312,423. 90[/tex]
Therefore, the compound interest is 312,423.90

A family has $1,000 to invest and is considering two options: investing in government bonds that offer 2% simple interest, or investing in a savings account at a bank, which charges a $20 fee to open an account and pays 2% compound interest. Both options pay interest annually.
The family would more likely choose the stock option, if the period of investment is 20 years,after calculating the simple & compound interest.
$999.60 is 1.02 times $980, and $1,019.59 is 1.02 times $999.60.
They may choose bonds or savings account depending on the assumptions they make about the time frame of the investment.
The value of the bonds b=1,000+20x and value of the stocks is s=980⋅(1.02)x , where x is the number of years since the investment were made.
For 10 years, the value of the bond will be
b=1,000+200=1,200 dollars.
The value of the stock will be s=980⋅(1.02)10≈1,195 dollars.
They should choose the bond option if the period of investment is 10 years.
For 20 years, the value of the bond will be
b=1000+400=1,400 dollars.
The value of the stock will be 980⋅(1.02)20=1,456980⋅(1.02)20=1,456 dollars.
So they choose the stock option, if the period of investment is 20 years.

Let n be a non-negative integer. Then the number of divisors of the form "4n + 1" of the number (10)10. (11)11. (13)13 is equal to_____
The number of divisors of 1730 of the form 4n + 1 is 20.
What do you mean by integers?An integer is a whole number, meaning it can be positive, negative, or zero, but it cannot be a fraction or a decimal. Integers are a subset of real numbers, which also include fractional and decimal numbers.
Integers are commonly used in mathematics and computer science for counting and for performing arithmetic operations such as addition, subtraction, multiplication, and division. They are also used to represent the magnitude of a quantity, such as the number of items in a set or the time elapsed in seconds.
In computer programming, integers are often stored as binary numbers, which are sequences of bits that represent positive or negative whole numbers. Different computer architectures have different numbers of bits for representing integers, with common sizes being 8, 16, 32, and 64 bits.
The number (10)10. (11)11. (13)13 is equal to 11 × 13 × 10 = 1730 in decimal.
A divisor of a number can be represented as (4n + 1) where n is a non-negative integer.
To find the number of divisors of 1730 of the form 4n + 1, we need to find the number of factors of 1730 that can be expressed as 4n + 1.
First, we find the prime factorization of 1730:
1730 = 2 × 3 × 5 × 29
Since 1730 is an odd number, one of its divisors must also be an odd number.
The only possible values for n are 0, 1, 2, ..., (number of odd divisors - 1).
In this case, the number of odd divisors of 1730 can be calculated as:
(number of ways to choose 0 odd factors) × (number of ways to choose 1 odd factor) × (number of ways to choose 2 odd factors) × ... × (number of ways to choose 4 odd factors)
= 1 × 4 × 5 × 1 = 20
Thus, the number of divisors of 1730 of the form 4n + 1 is 20.
