The value of the function when the quantity f divided by g of 8 is given by option D. 5.
The function are equal to,
f(x) = 3x + 1
g(x) = x - 3
The expression 'f divided by g of 8' means it is required to evaluate the function f(x) divided by g(x) at x=8.
First, find the individual values of function f(8) and g(8) is equal to,
f(x) = 3x + 1
Substitute the value of x = 8 we get,
⇒ f(8) = 3(8) + 1
⇒ f(8) = 25
Now, for the function g(x),
g(x) = x - 3
Substitute the value of x = 8 we get,
⇒ g(8) = 8 - 3
⇒ g(8) = 5
Then, we can find the value of f(x) divided by g(x) at x=8 which is equal to,
f(x) / g(x)
= ( 3x + 1 )/ ( x - 3 )
= f(8) / g(8)
= 25 / 5
= 5
Therefore, the quantity function f divided by g of 8 is 5, which is option (D).

Find the indicated functional value for the ceiling function: f(−0.75)?
A. -1
B. 1
C. 2
D. 0
The ceiling function, denoted by ⌈x⌉, gives the smallest integer that is greater than or equal to x. Therefore, ⌈-0.75⌉ is the smallest integer that is greater than or equal to -0.75.
Since -1 is the smallest integer that is greater than or equal to -0.75, we have:
⌈-0.75⌉ = -1
Therefore, the functional value for the ceiling function at -0.75 is -1.

Mr. Greene created a data set that represents the daily high temperatures, in degrees Fahrenheit, in his city over a week. The values in the table describe the data set. Minimum 73 Mean 77.86 Mean Absolute Deviation 2.73 Median 79 Interquartile Range 6 Maximum 82 Mr. Greene wants to use a single number that summarizes the temperatures for each day. Which value should he use? A. interquartile range B. mean absolute deviation C. mean D. maximum
The correct option is C. mean, that is Mr. Greene should use the mean temperature, which is 77.86°F.
What is a mean value?In mathematics, the mean value is a measure of central tendency of a set of numbers. It is also known as the arithmetic mean and is found by adding all the numbers in a set and dividing the sum by the total number of values. The mean is commonly used to represent the typical or average value of a set of data. It is a useful tool in statistics and other branches of mathematics for analyzing data and making predictions. The mean value can be affected by outliers or extreme values in a set of data, which can skew the results. However, in many cases, the mean provides a reliable and useful measure of central tendency.
Mr. Greene should use the mean temperature, which is 77.86°F, to summarize the temperatures for each day. The mean is a good measure of central tendency when the data set is approximately symmetric and has no significant outliers, which appears to be the case here. Additionally, using the mean will provide a single number that is representative of the entire data set. The interquartile range and mean absolute deviation are measures of spread and do not provide a summary of the temperatures for each day, and the maximum temperature is just one value and may not be representative of the entire data set.

Convert the rectangular coordinates (-√√2, -√2) into polar form.
Express the angle using radians in terms of 7 over the interval
0 ≤0 < 27, with a positive value of r.
The polar form of the rectangular coordinates (-√√2, -√2) is (2√(1 + √2), 15π/28)
Converting into polar formTo convert the rectangular coordinates (-√√2, -√2) into polar form, we first need to find the value of r (the radius) and θ (the angle).
r = √((-√√2)^2 + (-√2)^2) = √(2 + 2√2) = 2√(1 + √2)
To find the value of θ, we can use the following formula:
θ = atan(y/x)
where atan is the inverse tangent function, and (x, y) are the rectangular coordinates.
θ = atan(-√2/(-√√2)) = atan(√2) = π/4 radians
However, we need to express the angle in terms of 7 over the interval 0 ≤ θ < 2π/7, with a positive value of r.
To do this, we can add a multiple of 2π/7 to the value of θ until we get an angle in the desired interval.
θ = π/4 + 2π/7 = (7π + 8π)/28 = 15π/28 radians

A chemical company makes two brands of antifreeze. The first brand is 35% pure antifreeze, and the second brand is 60% pure antifreeze. In order to obtain 70 gallons of a mixture that contains 55% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Therefore , the solution of the given problem of percentage comes out to be 14 gallons of the first brand and 56 gallons of the second brand must be utilised.
What is percentages?In statistics, a figure or metric than may be presented as a percentage or 100 is denoted by the abbreviation "a%". Another unusual spelling is "pct," "pct," and "pc." The percent symbol ("%") is the method that is most usually used for this. Additionally, there are no indications or predetermined ratios of any component to the whole. Numbers are effectively integers since they frequently add up to 100.
Here,
Let's write "x" for the first brand's (35% pure antifreeze) number of gallons and "y" for the second brand's (60% pure antifreeze) number of gallons.
Given:
70 gallons of mixture are required in total.
Desired antifreeze content in the combination is 55%
Based on the information provided, we can construct the following system of equations:
=> Equation 1: x + y = 70
=> Equation 2: 0.5*70 = 0.55x + 0.60y
=> x = 70 - y
=> 0.35(70 - y) + 0.60y = 0.55 * 70
=> 24.5 - 0.35y + 0.60y = 38.5
=> 0.25y = 14
=> y = 56
=> x = 70 - 56
=> x = 14

Solve the following triangles:
A = 60 degree, a = 4, b = 5
The solution of missing sides and angle is: A = 60°, B = 34.8°, C = 85.2° a = 4, b = 5, c = √21
What is the main purpose of trigonometry and how many kinds of trigonometry are there?Trigonometric functions are used to obtain unknown angles and distances from known or measured angles in geometric drawings.
Basics of Trigonometry deals with measuring angles and problems related to angles. There are six basic trigonometric ratios: sine, cosine, tangent, cosecant, secant, and cotangent. All important trigonometric concepts are based on these trigonometric relationships or functions.
Solving a triangle means determining all its angles and sides. In this case, we are given angle A and sides a and b, and we want to find the remaining angles and sides.
First, we can use the law of cosines c to find the third side:
c² = a²+ b² - 2ab cos(A)
c² = 4² + 5² – 2(4)(5) cos(60)
c² = 16 + 25 - 40 cos (60)
c² = 41-20
c² = 21
c = √21
Now that we have all three sides, we can use the law of cosines to find the remaining angles:
cos(B) = (a²+ c² – b²) / (2ac)
cos(B) = (4² +(√21)² – 5²) / (2(4) (√21))
cos(B) = (16 + 21 - 25) / (8√21)
cos(B) = 12 / (8√21)
B = cos⁻¹ (12 / (8√21))
cos(C) = (a²+ b² – c²) / (2ab)
cos(C) = (4² + 5² – (√21)²) / (2(4)(5))
cos(C) = (16 + 25 - 21) / 40
cos(C) = 20/40
C = cos⁻¹ (20/40)
Simplifying trigonometric functions:
B ≈ 34.8°
C = 85.2°
Therefore, the solution is:
A = 60°, B = 34.8°, C = 85.2°
a = 4, b = 5, c = √21

(m+3)(m-3)
Answer:
The answer to (m+3)(m-3) is m^2-9.
Step-by-step explanation:
We will use distributive law to solve this question.
m(m-3)+3(m-3)
= m^2-3m+3m-9
= m^2-9 (since, 3m-3m=0)
As an alternative method, we can use the direct rule learned in algebra: (a+b)(a-b)=a^2-b^2.
so, here a=m and b=3.
(m+3)(m-3)
=m^2-3^2
=m^2-9

To purchase $14,500 worth of restaurant equipment for her business, Debra made a down payment of $1300 and took out a business loan for the rest. After 2 years of paying monthly payments of $585.04, she finally paid off the loan.
(a) What was the total amount Debra ended up paying for the equipment (including the down payment and monthly payments)?
(b) How much interest did Debra pay on the loan?
The total amount Debra ended up paying for the equipment was $28,541.60 and the amount of interest Debra paid on the loan was $14,041.60
(a) To find the total amount Debra ended up paying for the equipment (including the down payment and monthly payments), we need to add the down payment to the total amount of the loan, and then add the total amount of the monthly payments made over the two years.
Total amount of the loan = $14,500 - $1,300 (down payment) = $13,200
Total amount paid = Down payment + Total amount of the loan + Total amount of monthly payments
Total amount paid = $1,300 + $13,200 + ($585.04 x 24) [since there are 24 monthly payments in 2 years]
Total amount paid = $1,300 + $13,200 + $14,041.60
Total amount paid = $28,541.60
Therefore, the total amount Debra ended up paying for the equipment (including the down payment and monthly payments) was $28,541.60.
(b) To find the amount of interest paid on the loan, we need to subtract the total amount borrowed from the total amount paid, and then subtract the down payment. This will give us the total amount of interest paid over the two years.
Total interest paid = Total amount paid - Total amount borrowed - Down payment
Total interest paid = $28,541.60 - $13,200 - $1,300
Total interest paid = $14,041.60
Therefore, the amount of interest Debra paid on the loan was $14,041.60.
