Find the 7th term of the geometric sequence whose common ratio is 2/3 and whose first term is 8
we know that general term for gp is [tex]a_{n}[/tex] = a [tex]r^{n-1}[/tex]
where r = common ratio
a = first term
putting values we get
8th term = 8x 64/729
= 0.702
hence the 8th term is 0.702

What is the slope of the line that passes through
the points (2,-4) and (2, 4)?
A. -3 B.0. C.8. D. Undefined
The line is a vertical line, then the correct option is D, the slope is undefined.
How to find the slope of the line?A general linear equation can be written as:
y = a*x + b
Where a is the slope, b is the y-intercept, and x is the variable.
If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope of that line is given by the formula:
a = (y₂ - y₁)/(x₂ - x₁)
Here we know that the two points are (2, -4) and (2, 4)
Replacing that we would have a problem, that is because we have the same x-value in both points.
Then we have a vertical line at x = 2.
That line has no defined slope, thus, the correct option is D.

Office Services An auto mechanic has total receipts of $1861.16 for a certain day. He determines that $1240 of this is labor. The remaining amount is for parts plus 6% sales tax on the parts only. Find the amount of the sales tax he collected.
The amount of sales tax he collected from the office services would be =$658.43
How to calculate the amount of sales tax?To calculate the amount of sales tax,the percentage tax amount should be determined as follows.
The total receipts from the office services = $1861.16
The amount that is for labor = $1240
The amount for parts = 1861.16-1240
= $621.16
The tax amount = 6/100 × 621.16
= 3726.96/100
= $37.27
Therefore the amount sale tax = 621.16+37.27 = $658.43

The given statement "there is some k∈I such that [tex]D_{i}[/tex]⊆[tex]D_{k}[/tex] and [tex]D_{j}[/tex]⊆[tex]D_{k}[/tex]means that there is a set [tex]D_{k}[/tex] in a collection of sets I that contains all the elements of both sets [tex]D_{i}[/tex] and [tex]D_{j}[/tex].
For example, let's say we have a collection of sets I that includes sets A, B, C, D, E, and F. If we have two sets [tex]D_{i}[/tex] and [tex]D_{j}[/tex], where [tex]D_{i}[/tex] is the set of all even numbers, and [tex]D_{j}[/tex] is the set of all positive integers less than or equal to 10, then we can say that there exists a set [tex]D_{k}[/tex] in I that contains both [tex]D_{i}[/tex]and [tex]D_{j}[/tex] as subsets.
In this case, the set [tex]D_{k}[/tex] could be the set of all even positive integers less than or equal to 10. This set contains all the elements of [tex]D_{i}[/tex] and [tex]D_{j}[/tex], making them both subsets of [tex]D_{k}[/tex]. The statement "there is some k belongs I such that [tex]D_{i}[/tex] is a subset of [tex]D_{k}[/tex] and [tex]D_{j}[/tex] is a subset of [tex]D_{k}[/tex]" is a way to express this relationship between the sets.

Monthly you should deposit approximately $241 to accumulate $ 85,000 in 18 years.
Given that,
f = 85000
r = 6% = 0.06/12 = 0.005

The match to A line that has a slope of 5/3 and a y-intercept of 4 is 2y - x = -4.
We are given that;
The four equations to match from
Now,
Using the slope-intercept form, we can plug in m = 3/2 and b = -8:
y = (3/2)x - 8
This equation matches with y = 3/2x - 5 if we multiply both sides by 2:
2y = 3x - 16
Therefore, the correct equation is 2y - x = -16.
A line that contains the points (0,-2) and (4,0)
m = (0 - (-2)) / (4 - 0) m = 2 / 4 m = 1/2
Then we can plug in m = 1/2 and any of the given points to find b. For example, using (0, -2), we have:
-2 = (1/2)(0) + b -2 = b
Therefore, the equation is:
y = (1/2)x - 2
This equation matches with -5x - 3y = -12 if we multiply both sides by -6:
6y = -3x + 12
Therefore, the correct equation is -5x - 3y = -12.
A line that contains the y-intercept (0-2) and the slope of -3/4
Using the slope-intercept form, we can plug in m = -3/4 and b = -2:
y = (-3/4)x - 2
This equation matches with y = -3/4x - 2.
A line that has a slope of 5/3 and a y-intercept of 4
Using the slope-intercept form, we can plug in m = 5/3 and b = 4:
y = (5/3)x + 4
This equation matches with 2y - x = -4 if we multiply both sides by 3:
3y = (5/3)x + 12

The two inequalities that the graph represents are:

y ≤ ²/₃x - 4
How to interpret the Inequality Graph?An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
The formula for the equation of a line in slope intercept form is:
y = mx + c
where:
m is slope
c is y-intercept
The first inequality is the one with the dashed line and a y-intercept of 4 and so since shaded below line, we will use the symbol <.
The slope from two coordinates on the line (0, 4) and (4, 0) is:
(0 - 4)/(4 - 0) = -1
Thus, inequality is:
y < -x + 4
The first inequality is the one with the solid line and a y-intercept of -4 and so since shaded below line, we will use the symbol ≤.
The slope from two coordinates on the line (0, -4) and (6, 0) is:
(0 + 4)/(6 - 0) = 2/3

A bushel of apples costs $15.00 in the U.S. The same apples cost 1,600 yen in Japan. If the exchange rate is 80 yen per dollar, what is the real exchange rate? Is there a possibility for arbitrage? Explain and defend your answer.
The real exchange rate is 0.75.
It is not possible to make a profit by buying apples in one country and selling them in another.
We have,
To find the real exchange rate, we need to compare the price of apples in the two countries in terms of their respective currencies.
In the U.S., a bushel of apples costs $15.00.
In Japan, the same apples cost 1,600 yen.
Using the exchange rate of 80 yen per dollar, we can convert the cost in yen to dollars:
1,600 yen / 80 yen per dollar
= $20.00
So, the price of a bushel of apples in Japan is equivalent to $20.00 in the U.S.
The real exchange rate is the ratio of the prices of the same goods in two different countries, taking into account the exchange rate.
In this case, the real exchange rate is:
Real exchange rate = Price in U.S. / Price in Japan
= $15.00 / $20.00
= 0.75
This means that it takes 0.75 U.S. dollars to buy the same goods in Japan which would cost 1 Japanese yen.
To determine if there is an arbitrage opportunity, we need to compare the real exchange rate with the actual exchange rate.
If the real exchange rate is greater than the actual exchange rate, there is an arbitrage opportunity for someone to buy the good in one country and sell it in another country for a profit.
However, if the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.
In this case,
The real exchange rate is 0.75, while the actual exchange rate is 80 yen per dollar, or 0.0125.
Since the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.
Therefore,
The real exchange rate is 0.75.

107 over 103 times 101 over 100 would result in 10807/10300.
Mathematical operationsIn order to multiply the fractions 107/103 and 101/100, we can simply multiply their numerators together and their denominators together:
(107/103) x (101/100) = (107 x 101) / (103 x 100)
Now we can simplify this fraction by finding the greatest common factor of the numerator and denominator and dividing both by it:
(107 x 101) / (103 x 100) = 10807 / 10300
Therefore, 107/103 times 101/100 simplifies to 10807/10300.

a certain forest covers an area of 1700km^(2). Suppose that each year this area descreases by 7.5%. What will the area be after 11 years?
round your answer to the nearest square kilometer.
The area of the forest after 11 years will be 298 km².
To calculate the area of the forest after 11 years, we need to decrease the initial area of 1700 km² by 7.5% each year for 11 years.
First, let's calculate the decrease in area for one year:
Decrease in area for one year = 7.5% of 1700 km²
7.5% of 1700 km² = (7.5/100) × 1700 km²
= 127.5 km²
Now, we can calculate the total decrease in area over 11 years:
Total decrease in area over 11 years = 11 × 127.5 km² = 1402.5 km²
Finally, we can subtract the total decrease in area from the initial area to get the area of the forest after 11 years;
Area of the forest after 11 years = Initial area - Total decrease in area
= 1700 km² - 1402.5 km²
= 297.5 km²
Therefore, Rounding to the nearest square kilometer, the area of the forest after 11 years will be approximately 298 km².
