The amount after 10 years is $11,842.43
In continuous compounding the number of times by which compounding occurs tends to infinity.
In order to calculate the amount use the following formula
A= Pe^rt
where P represents the initial amount, e is the mathematical constant having value 2.7182, r is the rate of interest and t is the time period
Here the principal amount is $6000, r is 6.8 and time period t is 10 years
A = $6000 x 2.718⁽¹⁰ ˣ ⁶·⁸ %⁾
A = 6000 x 2.718⁽¹⁰ ˣ ⁶·⁸÷¹⁰⁰⁾
A = 6000 x 2.718 x 0.68
A = $ 11,842.43
Therefore the total amount calculated after 10 years is $ 11,842.43

Use the Change of Base Formula to evaluate each expression.
log₇30
The evaluated value of [tex]log_{7}30[/tex] is 1.748
Change of base formula is used to change the base of the logarithm. It is used to write a logarithm of a number with a given base as the ratio of two logarithms each with the same base that is different from the base of the original logarithm.
According to the change of base formula:
[tex]log_{a}b = \frac{log_{x}b }{log_{x} a}[/tex]
where base x is considered base 10
According to the question, we have to find the value of [tex]log_{7} 30[/tex]
Thus applying change of base formula we get
[tex]log_{7} 30 = \frac{log_{10} 30}{log_{10} 7}[/tex]
calculating the value of log from the calculator we get,

Find the values of the variables.
Determine if each statement is true or false. Justify your answer.
log₄7- log ₄3= log₄4
The given logarithmic expression statement is false. Because log₄7- log ₄3 = log₄(7/3).
The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.
Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

In a random sample of people, the mean commute time to work was minutes and the standard deviation was minutes. Assume the population is normally distributed and use a t-distribution to construct a % confidence interval for the population mean. What is the margin of error of ? interpret the results.
The margin of error is 3.083 min
Margin of Error: The margin of error is the range of error permitted around the sample statistic in order to estimate the population parameter. The margin of error indicates the size of the confidence interval. The breadth of the confidence interval increases with the margin of error.
Sample size, n=24
Sample mean, ¯x=31.5 min
Sample standard deviation, s=7.3 min
Confidence level, c=95%
=0.95
From the given information we can calculate the below-required quantities,
Significance level, α=1−c=1−0.95=0.05
Degrees of freedom, DOF=n−1
=24−1
=23
Now from the t-distribution table,
The value of t (α2, DOF) is,
t (0.025,23) = 2.069
Hence the margin of error will be,
MOE= t (α2, DOF) × s/√ n
=2.069×7.3/√24
=3.083 min
i. The upper limit of the confidence interval will be,
UL=¯x + MOE=31.5+3.083=34.583
The lower limit of the confidence interval will be,
LL=¯x−MOE
=31.5−3.083
=28.417
Hence, the 95% confidence interval is (28.417,34.583)
(28.417,34.583)
The answer is 28.417,34.583
ii. The required answer is MOE=3.083 min
ii. We have found the 95% confidence interval for the population mean to be (28.417,34.583). This means with 95 % confidence; it can be said that the population mean commute time is between the bounds of the confidence interval.

An equilateral triangle has a length of 10 inches.What is the area of the triangle in simplest radical form?
Answer: The area of Triangle is A = 43.25
Step-by-step explanation:
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3 [tex]s^{2}[/tex]* s = √3/4([tex]s^{2}[/tex])
Define Area of Triangle:
In an equilateral triangle, median, angle bisector and altitude for all sides are all the same and are the lines of symmetry of the equilateral triangle. The area of an equilateral triangle is √3/4([tex]s^{2}[/tex]) . The perimeter of an equilateral triangle is 3s.
So, we can write,
A = √3/4([tex]s^{2}[/tex])
It means, A = Area of the Triangle
S = length of Triangle = 10inches.
A = √3/4([tex]s^{2}[/tex])
A = √3/4([tex]10^{2}[/tex])
A= √3/4*100
A = 1.73/4*100
A = 0.4325*100
A = 43.25
The area of Triangle is A = 43.25

The time t in seconds for a swinging pendulum to complete one full cycle is given by the function t=0.2√I, where l is the length of the pendulum in centimeters. To the nearest tenth, how long is a full cycle if the pendulum is 10 cm long? 20cm long? How long, in centimeters, is a pendulum that takes 2 seconds for one full cycle?
A full cycle, if the pendulum is 10 cm, is 0.6 seconds long. A full cycle, if the pendulum is 20 cm, is 0.9 seconds long. A pendulum that takes 2 seconds for one full cycle is 100 cm long.
Given,
The time t in seconds for a swinging pendulum to complete one full cycle is given by the function t as,
t = 0.2 √I
Here, l is the length of the pendulum in centimeters.
For the first part, two lengths are given for the pendulum is given
We can obtain the value of t by substituting the value of l
This implies,
For l = 10 cm
t = 0.2 √10 = 0.632 = 0.6 seconds
For l = 20 cm
t = 0.2 √20 = 0.894 = 0.9 seconds
For the second part, time is given
We can obtain the value of l by substituting the value of t
This implies,
For t = 2 seconds
l = t² / (0.2)² = t² / 0.04 = 2² / 0.04 = 4 / 0.04 = 100 cm
Therefore, A full cycle is 0.6 seconds long if the pendulum is 10 cm long, 0.9 seconds long if the pendulum is 20 cm long, and 100 cm long if the pendulum takes 2 seconds to complete one full cycle.

Answer:

Step-by-step explanation:
The lengths of the four sides of a quadrilateral (in inches) are consecutive odd integers. if the perimeter is 120 inches, find the value of the longest of the four side lengths.
In a quadrilateral with a perimeter of 120 inches, the longest of the four sides has length equal to 33 inches.
A quadrilateral is a two-dimensional figure that has 4 sides and 4 vertices. The perimeter of any two-dimensional figure is the sum of all its sides.
If the lengths of the four sides of a quadrilateral (in inches) are consecutive odd integers, we can express each side as:
x = length of side 1(odd integer)
x + 2 = length of side 2
x + 4 = length of side 3
x + 6 = length of side 4
If the perimeter of the quadrilateral is 120 inches, then the sum of the four sides is equal to 120 inches.
x + (x + 2) + (x + 4) + (x + 6) = 120
Simplifying and solving for x.
4x + 12 = 120
4x = 108
x = 27
Substitute the value of x on the expression for the length of the 4th side(longest side).
