if f(x)=3+x/x-3, What is f(a+2)
Answer:
f(a + 2)= (5 + a) / (a - 1) or f(a+2)= (a+5)/(a-1)
Step-by-step explanation:
f(x)=(3+x)/(x-3)
To evaluate f(a+2), simply replace the x with a+2
f(a+2) = (3 + a+2)/(a+2 - 3)= (a+5)/(a-1)
or
To answer items such as this, we directly substitute the a + 2 to the all the x's in the function:
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above:
f(a + 2) = (5 + a) / (a - 1)
Step-by-step explanation:
f(x) = 3+x/x-3
Substituting x = a+2, we get
[tex]f(a + 2) = \frac{3 + (a + 2)}{(a + 2) - 3} \\ f(a + 2) = \frac{a + 5}{a - 1} [/tex]
which is the final answer.

HELP PLEASE I NEED THIS ANSWER AND SHOWN WORK NOWWW ASAP PLEASEEE
Answer:
D
Step-by-step explanation:
Since the constructed line is a perpendicular bisector of the line AB, then
AC = BC ← substitute values
4x + 12 = 2x + 18 ( subtract 2x from both sides )
2x + 12 = 18 ( subtract 12 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Hence
AB = 2AC = 2(4x + 12) ← substitute x = 3
AB = 2(12 + 12) = 2 × 24 = 48 → D

I think th answer is $0.82.
Hope this helps
Answer:
$ 0.83 on one pound
Step-by-step explanation:
Given: Martha spent $2.90 on 3 1\2 pounds of bananas.
To Find: How much did she spend on each pound of bananas
Solution:
Amount spent by martha on bananas = [tex]\$[/tex] [tex]2.90[/tex]
Quantity of bananas bought = [tex]3\frac{1}{2}[/tex] [tex]\text{pound}[/tex]
= [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex]
Now,
Martha spent [tex]\$[/tex] [tex]2.90[/tex] on = [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex] of bananas
therefore,
Amount spent by Martha on one pound of banana= [tex]\frac{\text{quantity of banana bought}}{\text{Amount spent on bananas}}[/tex]
= [tex]\frac{2.90}{\frac{7}{2}}[/tex]
= [tex]\frac{2.90\times2}{7}[/tex]
= [tex]\$[/tex] [tex]0.83[/tex]
Hence amount spent by martha on one pound of banana is [tex]\$[/tex] [tex]0.83[/tex]
The table shows the number of subscribers to several Internet providers. Determine if each statement is true or false.
TABLE:
Internet Provider Subscribers:
Company A - 2.45
Company B - 3.12
Company C - 2.83
QUESTIONS:
A. Company B earned $119 million last month. Each subscriber paid about $40.
B. Company A earned $108 million last month. Each subscriber paid about $30.
Guys please help.
Answer:
A - True
B - False
Step-by-step explanation:
Looking at option A,
Company B had 3.12 subscribers and earned 119. To find each subscriber's value we divide 119 by 3.12
119/3.12 = 38.14
Looking at Option B,
Company A had 2.45 subscribers and earned 108. To find each subscriber's value, we divide 108 by 2.45
108/2.45 = 44.08
Hence, for Option A, each subscriber paid about $40 is correct because it's close to 38.14
For Option B, each subscriber paid about 30 is incorrect since it's way over, 44.08.
Thus,
A - True
B - False

If we convert 22,647 inches into miles, we can get 0.357433710227 miles.
What are miles?The mile, sometimes known as the international mile or the statute mile to differentiate it from other miles, is a British imperial unit and a customary unit of distance in the United States; both are based on the older English unit of length equal to 1,760 yards.
What are yards?Yards are a measurement that is 36 inches long (or wide) in US units.
How to solve this problem?We have to convert 22,647 inches into miles.
Since 36 inches = 1 yard,
1 inch = 1/36 yards
i.e. 22,647 inches = 22,647/36 yards = 629.08333 yards.
Since 1,760 yards = 1 mile,
1 yards = 1/1760 miles
i.e. 629.08333 yards = 629.08333/1760 miles = 0.357433710227 miles
Therefore if we convert 22,647 inches into miles, we can get 0.357433710227 miles.

Simplify tan 9x - tan 5x / 1 + tan 9x tan 5x.
Simplification of [tex]\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}[/tex] is tan 4x
Solution:
By using sum-difference formula for tangent,
Tangent of difference between two angles is written as,
[tex]\tan (x-y)=\frac{\tan x-\tan y}{1+\tan x \tan y}(\text { Equation } 1)[/tex]
By comparing the above equation 1 with [tex]\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}[/tex] ,
we get x = 9x and y = 5x
By substituting x = 9x and y = 5x in equation 1,
[tex]\begin{array}{l}{\tan (9 x-5 x)=\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}} \\\\ {\tan (4 x)=\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}} \\\\ {\text { Therefore, } \frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}=\tan 4 x}\end{array}[/tex]
Hence by using difference formula for tangent, [tex]\frac{\tan 9 x-\tan 5 x}{1+\tan 9 x \tan 5 x}[/tex] is simplified as tan4x

a sewage treatment plant has two inlet pipes to its settling pond. one piece can fill the pond 3 times as fast as the other pipe, and together they can fill the pond in 12 hours. how long will it take the faster pipe to fill the pond alone
Answer:
The faster pipe will take 16 hours to fill the pond alone
Step-by-step explanation:
* Lets explain how to solve the problem
- A sewage treatment plant has two inlet pipes to its settling pond
- One pipe can fill the pond 3 times as fast as the other pipe
∴ The rate of the faster pipe is 3 times the rate of the second pipe
- The rate and the time are inverse proportion because;
time = job/rate and the job here is constant (fill pool), then
time × rate = constant
∵ The rate of the faster pipe is 3 times the rate of the second pipe
∴ The time of the second pipe is 3 times the time of the faster pipe
- Assume that the time of the faster pipe is t
∵ The time of the faster pipe is t
∴ The time of the second pipe is 3t
- Together they can fill the pond in 12 hours
∴ [tex]\frac{1}{3t}+\frac{1}{t}=\frac{1}{12}[/tex]
- The L.C.M of 3t and t is 3t
∴ [tex]\frac{1}{3t}+\frac{3}{3t}=\frac{1}{12}[/tex]
∴ [tex]\frac{1+3}{3t}=\frac{1}{12}[/tex]
∴ [tex]\frac{4}{3t}=\frac{1}{12}[/tex]
- By using cross multiplication
∴ 48 = 3t
- Divide both sides by 3
∴ t = 16
∵ t represents the time of the faster pipe
∴ The time of the first pipe is 16 hours
* The faster pipe will take 16 hours to fill the pond alone
Final answer:
The faster pipe will take 6 hours to fill the sewage treatment pond by itself, calculated by setting up and solving a rate problem based on the information provided.
Explanation:
To determine how long it will take for the faster pipe to fill the sewage treatment pond alone, we can set up a rate problem where the pipes are filling the pond at their rates and a combined rate.
Let's define the rate of the slower pipe as 1/x ponds per hour (where x is the number of hours it takes the slower pipe alone to fill the pond). This means that the faster pipe works at a rate of 3/x (since it's three times as fast).
Combined, their rate is 1/12 ponds per hour (because together they fill the pond in 12 hours). Our equation will now look like this: 1/x + 3/x = 1/12.
Solving this equation, we find that x, the time it takes for the slower pipe to fill the pond alone, is 18 hours. Therefore, the faster pipe, being three times as fast, will take 18 hours divided by 3, which equals 6 hours to fill the pond alone.

The combined area of a square and 4 semicircles with each semicircle's diameter equal to the side length (15 cm) of the square is approximately 578.42 cm², hence the closest approximation is 580 cm².
Explanation:To find the closest approximation of the area of a figure that consists of a square and 4 semicircles, where the diameter of each semicircle is equal to the sides of the square (15 cm), we must first calculate the area of the square and then the combined area of the semicircles.
The area of the square (Area_square) is given by the formula:
Area_square = side × side = 15 cm × 15 cm = 225 cm²The area of a full circle with a diameter of 15 cm is:
Area_circle = πr²Since the diameter is 15 cm, the radius (r) is 7.5 cmArea_circle = π(7.5 cm)² ≈ 176.71 cm²The total area of the 4 semicircles is:
Total_semicircles_area = 4 * (0.5 * Area_circle) = 2 * Area_circle ≈ 2 * 176.71 cm² ≈ 353.42 cm²Add the area of the square to the combined area of the 4 semicircles to obtain the total area:
Total_area = Area_square + Total_semicircles_area ≈ 225 cm² + 353.42 cm² ≈ 578.42 cm²Based on this calculation, the closest approximation from the options provided is 580 cm².
