given: f(x) = x + 2 and g(x) = 3x + 5
f (x)/g (x) =
For this case we have two functions of the form y = f (x). We must find the quotient of the following functions:
[tex]f (x) = x + 2\\g (x) = 3x + 5[/tex]
So, we have by definition:
[tex]\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}[/tex]
Answer:
[tex]\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}[/tex]
with 3x + 5 different from zero, so that the function is defined
Answer:
[tex]\frac{f(x)}{g(x)}=\frac{x+2}{3x+5}[/tex]
where [tex]x\ne -\frac{5}{3}[/tex]
Step-by-step explanation:
The given functions are:
f(x) = x + 2 and g(x) = 3x + 5
[tex]\frac{f(x)}{g(x)}=\frac{x+2}{3x+5}[/tex]
Since this is a rational function, the function will not be defined where denominator equals zero.
We need to restrict the function or define the domain.
This is a rational function defined for [tex]x\ne -\frac{5}{3}[/tex]
you invested your allowance of $270 which gets 15% compounded annually for 3 years. How much will you have in 3 years
____________________________________________________
Answer:
Your answer would be $410.64
____________________________________________________
Step-by-step explanation:
In order to find the amount of money you would have in 3 years, you would have to multiply the principal each time by 15% 3 times.
We would start with our starting allowance, and multiply that by 1.15, and so on:
270 × 1.15 = 310.50
310 × 1.15 = 357.075
357.073 × 1.15 = 410.636
Since we have three numbers after the decimal, we would want to round up to the nearest hundredth because that's how the value of money works. Cents only go up to the hundredths place.
We would round the 6 to the three, in which would make the three turn into 4. When you round, the numbers 1-4 would keep the number before it the same, 5-9 would make the number before it go up by 1.
410.636 would turn into 410.64.
You would have $410.64 dollars in three years.
____________________________________________________
With a principal of $270 and an annual compound interest rate of 15%, your investment will grow to approximately $410.64 in 3 years.
To determine how much your investment of $270 will grow in 3 years with an annual compound interest rate of 15%, you can use the compound interest formula:
A = P(1 + r/n)ⁿᵗ
Where:
A = the future value of the investment/loan, including interestP = the principal investment amount ($270)r = the annual interest rate (decimal) (0.15)n = the number of times that interest is compounded per year (1, since interest is compounded annually)t = the number of years the money is invested or borrowed for (3)Now plug in the values:
A = 270(1 + 0.15/1)¹*³Simplify inside the parenthesis:
A = 270(1 + 0.15)³Then:
A = 270(1.15)³Calculate the exponent:
A = 270 * 1.520875Finally, multiply:
A ≈ 410.64After 3 years, your investment will grow to approximately $410.64.
This demonstrates the power of compound interest, which is an important concept to understand when investing.
11) Given that the points (-1, 6), (3, 6), (3, 1), and (-1, 1) are vertices of a rectangle, how much shorter is the width than the length?
A) -5 units
B) -4 units
C) -3 units
D) -2 units
E) -1 unit
-1 unit is the correct answer.
By calculating the distances between the horizontal and vertical points of the rectangle, we find that the width is 1 unit shorter than the length.
Explanation:To determine how much shorter the width is than the length of the rectangle formed by the points (-1, 6), (3, 6), (3, 1), and (-1, 1), we can calculate the distances between the points.
The length can be measured either between the first and second point or the third and fourth, as they have the same y-value but different x-value, which is a horizontal distance on the graph.
The width can be measured between the first and fourth point or the second and third point since they share the same x-value but differ in y-values, constituting a vertical measurement.
Length is distance between (-1, 6) and (3, 6) or (3, 1) and (-1, 1) which is |3 - (-1)| = 4 units. Width is the distance between (-1, 6) and (-1, 1) or (3, 6) and (3, 1) which is |6 - 1| = 5 units.
The width is longer than the length, so to find out how much shorter the width is compared to the length, we subtract the two: 4 - 5 = -1 unit.

Amanda says that a human fingernails has a thickness of about 4.2 x 10^-4 meter. Justin says that a human fingernails has a thickness of about 0.42 millimeters .
What is the width in meters written in standard notation?
Do Justin’s and Amanda’s measurements agree? Explain .
Explain why Justin’s estimate of the thickness of a human fingernail is made appropriate than Amanda’s estimate.
Answer:
See below
Step-by-step explanation:
1. Standard notation
4.2 × 10⁻⁴ m
A negative exponent indicates
A number between 0 and 1. That the decimal point is shifted that number of places to the left.4.2 × 10⁻⁴ tells you that the decimal number is 4.2, with the decimal point moved four places to the left.
The number becomes 0.000 42 .
2. Metres to millimetres
[tex]4.2 \times 10^{-4}\text{ m} \times \dfrac{10^{3}\text{ mm}}{\text{1 m}} = 4.2\times 10^{-1}\text{ mm = 0.42 mm}}[/tex]
3. Measurements agree?
Yes, because both measurements are the same as 0.42 m.
4. More appropriate measurement
Most measurements should be expressed as a number between 0.1 and 1000, because most people aren’t particularly good at visualizing larger or smaller numbers.
Justin's measurement of 0.42 mm is more appropriate than Amanda's measurement of 4.2 × 10⁻⁴ m.

What is 6.25 % of 14.99
Hello There! 6.25% of 14.99 is about $0.94, or 0.936875 to be exact.
To find a percentage of a number, switch the percentage into a decimal and multiply the original number by this decimal.
To convert percentages to decimals, divide them by 100.
6.25 ÷ 100 = 0.0625
Now, multiply 14.99 by 0.0625.
14.99 x 0.0625 = 0.936875.
This can be rounded to the nearest cent, or the hundredths place, and since the thousandths place is above five, round up to six. You now have a total of about $0.94.

which statement best describes the end behavior of the following function? f(x)=3x^5+x^3-x+11
Answer:
(d)
Step-by-step explanation:
(d) is correct. This being a 5th power of x, the graph starts in Quadrant III and continues growing into Quadrant I. This is true of any positive odd power of x.
The best statement describes The graph of the function starts low and ends high.
The Option (d) is correct.
The end behavior of a polynomial function is determined by its leading term, which is the term with the highest degree. The coefficients of the leading term also play a significant role.
For the function [tex]\( F(x) = 3x^5 + 4x^3 - x + 11 \)[/tex], the leading term is[tex]\( 3x^5 \)[/tex]. Since the coefficient of[tex]\( x^5 \)[/tex] is positive, as[tex]\( x \)[/tex] approaches positive infinity[tex](\( x \to \infty \))[/tex], the function [tex]\( F(x) \)[/tex] will go to positive infinity [tex](\( F(x) \to \infty \))[/tex]. Similarly, as[tex]\( x \)[/tex]approaches negative infinity [tex](\( x \to -\infty \)),[/tex] the function [tex]\( F(x) \)[/tex] will go to negative infinity [tex](\( F(x) \to -\infty \))[/tex] because the leading term, being an odd power with a positive coefficient, will dominate and the sign will be negative due to the odd power.
So, the end behavior of the function is:
- Starts low (as[tex]\( x \)[/tex] goes to negative infinity,[tex]\( F(x) \)[/tex] goes to negative infinity).
- Ends high (as[tex]\( x \)[/tex] goes to positive infinity, [tex]\( F(x) \)[/tex] goes to positive infinity).
This corresponds to option D: "The graph of the function starts low and ends high."

Answer:
the number of non-farm jobs started going down in 2008
Step-by-step explanation:
The question presented requires the analysis and interpretation of graphical output of data.
From the graph it is true to say that the number of non-farm jobs did not remain consistent over time since the graph is moving down then up implying decrease followed by increase.
It is also true to say that the number of non-farm jobs started going up in 2010 as indicated by the upward trend of the graph.
From 2008 to around 2010 the graph is moving downwards suggesting that the number of non-farm jobs was declining.
