The required domain and the range of the given function is (0, ∞) and (-8, -2) respectively.
Given that,
A graph of the function is shown we have to determine the domain and range of the function with the help of the graph.
The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
Here,
As of the graph,
The graph describes as only the positive real number because the graph only consists of the positive x-axis, so the domain of the function is all positive real numbers. While the ordinate of the graph is describe for -8 to -2 on the negative y-axis thus the rang of the given function lies between -8 to -2.
Thus, the required domain and the range of the given function is (0, ∞) and (-8, -2) respectively.

What is the total company's net operating income?
Answers
The total company's net operating income (NOI) is $103,500.
What is a Net operating income?In accounting, a Net operating income refers to the figure that equals to all revenue from the property minus all reasonably necessary operating expenses.
The computation of the Net operating income is as follows:
= Gross Income - Operating Expenses
= (Sales+Sales) - [(variable expenses + variable expenses) + (fixed expenses + fixed expenses) + 137,200]
= (320,000+630,000) - [(158,100 + 343,800) + (72,300 + 135,100) + 137,200]
= 950,000 - (5,01,900 + 2,07,400 + 137,200)
= 950,000 - 8,46,500
= $1,03,500

Calculate the five-number summary and the IQR from the following values given: {17, 20, 21, 25, 25, 29, 40}
Answers
Answer:
• 17, 20, 25, 29 and 40
,• IQR=9
Explanation:
(a)Given the set of values:
{17, 20, 21, 25, 25, 29, 40}
• The minimum value = 17
The first quartile
The first quartile is the median of the lower half of the data set.
The lower half of the data set = 17, 20, 21
• Therefore, the first quartile =20
The Median
The median is the number in the middle of the set of values.
The number in the middle is 25, therefore:
• Median = 25
The third quartile
The third quartile is the median of the upper half of the data set.
The upper half of the data set = 25, 29, 40
• Therefore, the third quartile =29
Finally, Maximum Value = 40.
The five-number summary of the set of values is: 17, 20, 25, 29 and 40
(b)Interquartile Range
Interquartile Range = Third Quartile - First Quartile
=29 - 20

Answers
In order to convert from fluid ounce to pint, we need to know that 16 fluid ounces is equivalent to 1 pint.
Then, to find how many pints is 24 fluid ounces, we can use a rule of three:
[tex]\begin{gathered} 16\text{ fluid ounces}\to1\text{ pint} \\ 24\text{ fluid ounces}\to x\text{ pints} \\ \\ \frac{16}{24}=\frac{1}{x} \\ x=\frac{24}{16}=\frac{3}{2}=1\frac{1}{2} \end{gathered}[/tex]So 24 fluid ounces is equivalent to 1 1/2 pints, therefore the correct answer is C.

Answers
He spend $260 on 4 chairs:
To know how much he spent on each chair he must:
Divide 260 into 4You first pick the firt digit of the dividend (260) and look if you can divide that digit into the divider (4) as in this case the firt digit 2 cannot be divided into 4 you take the first and secon digit (26) and divide it into 4 (how many times fix 4 in 26), this is equal to 6 times (this is the first digit of the quotient), then you multiply the 6 by 4 (6*4=24)and put the result under the 26 to substract it:
Now you lower the zero (of the 260) next to the result of the previous subtraction:
And divide 20 into 4 (how many times fix 4 in 20) this is equal to 5 times (this is the second digit of the quotient ) then you multiply the 5 by 4 (5/4 =20) and put the result under the 20 to substract it:
The remainder of 0 means the division has not decimal result, the result of 260 into 4 is an interger number (65)
The firt digit of the quotient is 6 because 26 into 4 is 6.
So the division he did is the correct form to find how much cost each chair ($65)according to recent study 7 out of every 500 Americans aged 13-17, years are vegetarian.in a group of 350 13 to 17- years old about how many would you expect to he vegetarian

KM = 30 units
Tan M = (8/15)
Explanation
The Pythagoras Theorem is used for right angled triangle, that is, triangles that have one of their angles equal to 90 degrees.
The side of the triangle that is directly opposite the right angle or 90 degrees is called the hypotenuse. It is normally the longest side of the right angle triangle.
The Pythagoras theorem thus states that the sum of the squares of each of the respective other sides of a right angled triangle is equal to the square of the hypotenuse. In mathematical terms, if the two other sides are a and b respectively,
a² + b² = (hyp)²
For this question,
a = KM = ?
b = KL = 16
hyp = LM = 34
a² + b² = (hyp)²
KM² + 16² = 34²
KM² + 256 = 1,156
KM² = 1,156 - 256
KM² = 900
Take the square root of both sides
√(KM²) = √(900)
KM = 30 units
In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.
Using M as the given non-right angle,
Hypotenuse = LM = 34
Opposite = KL = 16
Adjacent = KM = 30
Using trignometric identities, we know that TOA means
Tan M = (Opp/Adj)
Tan M = (16/30)
Divide numerator and denominator by 2
Tan M = (16/30) = (8/15)

Answers
The total track lap time of the runner is 4 11/15 and it has been written as a mixed number or a fraction in lowest terms.
Mixed fraction:
The fraction represented with its quotient and remainder is known as mixed fraction.
Given,
A runner has a track lap time of 3 minutes while at a run, 5 minutes while at a jog, and 7 minutes while at a walk. If 2/5 of the lap is paced at a run, 1/2 at a jog, and 1/10 at a walk.
Here we need to find the total track lap time of the runner.
Here we can compute the Total Lap Time by multiplying each fraction by its associated lap time, then we get,
Run Lap Time = (2/5)(3) = 6/5 minutes
Jog Lap Time = (1/3)(5) = 5/3 minutes
Walk Lap Time = (4/15)(7) = 28/15 minutes
So, the total lap time is, written as,
Total Lap Time = 6/5 + 5/3 + 28/15
Now, we have to make the fraction equal to each other,
=> (6x3)/(5x3) + (5x5)/(3x5) + (28 x 1)(15 x1)
=> 18/15 + 25/15 + 28/15
=> (18 + 25 + 28)/15 = 71/15
Now, we have to convert this into mixed fraction then we get,
=> 71/15 = 4 11/15
Therefore, the total Lap Time is 4 11/15 minutes.

OB. 6 x 106
C. 5 × 105
D. 5 x 106
Answers
Answer: [tex]6 \times 10^6[/tex] which is choice B
==========================================
Method 1
5,846,000 rounds to 6,000,000 aka "6 million".
This converts to the scientific notation [tex]6 \times 10^6[/tex]
The first 6 is from "6 million", while the 6 as the exponent tells us to move the decimal point that many places to the right to go from 6.0 to 6,000,000
---------------
Method 2
Place a decimal point between the first two digits of 5,846,000 and erase the zeros at the end.
So we get 5.846
We must move the decimal point 6 spaces to the right to go from 5.846 back to 5,846,000 again
Therefore, [tex]5,846,000 = 5.846 \times 10^6[/tex]
Then the 5.846 rounds to 6.0 or simply 6 when rounding to the nearest whole number. This leads to [tex]6 \times 10^6[/tex]
