The function f(x) = 0.5x + 3 is used to estimate the number of pounds of potatoes a caterer plans to make depending on the number of
people being served, X. The mathematical domain for the function is the set of real numbers.
Which statement describes the limitation for the reasonable domain compared to the mathematical domain?
Options:
The reasonable domain contains only positive real numbers.
The reasonable domain contains only positive whole numbers.
The reasonable domain contains only real numbers greater than 3.
The reasonable domain contains only rational numbers greater than 3.
Answer:
(b) The reasonable domain contains only positive whole numbers.
Step-by-step explanation:
Given
[tex]f(x) = 0.5x + 3[/tex]

True statement about the limitation of the domain
Since the domain (x) represents people, then it must be a positive whole numbers
This eliminates options (a) and (c)
The range of the function is not given. So, we can assume that any number of people can be present.
This eliminates option (d).

65 passengers
At hour six, about 54 passengers will be on the boat.
What is the line of best fit?
A straight line that minimizes the gap between it and certain data is called a line of best fit. In a scatter plot containing several data points, a relationship is expressed using the line of best fit. It is a result of regression analysis and a tool for forecasting indicators and price changes.
Sum of X = 15
Sum of Y = 195
Mean X = 3
Mean Y = 39
The sum of squares (SSX) = 10
The sum of products (SP) = 50
Regression Equation = ŷ = bX + a
b = SP/SSX = 50/10 = 5
a = MY - bMX = 39 - (5*3) = 24
ŷ = 5X + 24
When x = 6,
we get ŷ = 5(6) + 24 = 54
Therefore, the approximate number of passengers is 54.

A bakery sold 36 chocolate-chip muffins. That was 45% of their total muffins sold that day. How many muffins did they sell in all?
o A. 80
OB. 86
O C. 98
O D. 70
Using the given percentage, we found that the total number of chocolate chip muffins sold is 80.
What is meant by percentage?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word per cent means. A % is a number without dimensions and without a standard measurement. The value of "whole" in this relationship between portion and whole is always set at 100.
Given,
the number of chocolate chip muffins sold = 36
The 36 muffins is the 45% of the total muffins sold.
Let the total number of muffins sold be x.
Then using the given percentage, we find the total muffins sold.
Percentage = (required number of muffins sold/ total number sold) *100
45% = 36/x * 100
0.45 = 36/x
x = 36/0.45 = 80
Therefore using the given percentage, we found that the total number of chocolate chip muffins sold is 80.

Latasha explores some passages in a cave. The elevations of the passages are all above - 10 meters. Let y be the elevation of a passage in meters. Write an inequality that represents elevations above -10 meters.
Answer:
It is y>-10
Step-by-step explanation:
i did it and i got it right.
The inequality that represents elevations above -10 meters is y > -10.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
The inequality y > -10 means that the elevation y of a passage is greater than -10 meters.
This represents all the elevations of passages that are above -10 meters, which is the given condition in the problem.
If the elevation is exactly -10 meters or below, then it does not meet the condition of being above -10 meters.
Therefore, any elevation that is greater than -10 meters satisfies this inequality, and any elevation that is less than or equal to -10 meters does not.
Thus,
The inequality that represents elevations above -10 meters is y > -10.

A student bought some markers in a pads of paper if the marker cost $2 each in the pads of paper cost $4 each he brought a items and all and spent $26 how many markers and how many pads of paper did he buy?
Answer:
$4
Step-by-step explanation:
We need to set up an algebraic expression to solve this problem:
Let n= cost of a notepad
Let p= cost of a pen
First set up an expression for Cynthia's purchase:
cost of notepads*number of notepads + cost of pens*number of pens = total cost
n*2 + p*3 = 40.30
Rewrite as:
2n + 3p = 40.30
Next, set up an expression for Annie's purchase:
Here we will be using the same variables
n*3 + p*5 = 61
Rewrite as:
3n + 5p =61
Now, set up a system of equations:
2n + 3p = 40.30
3n + 5p =61
A system of equations can be solved in several ways, here I will use the addition/elimination method
For this method one of the variables must be able to be eliminated
Step 1: Pick a variable to eliminate
Here I will eliminate n
Step 2: make the selected variables in the equations equal and opposite so that they cancel out when the equations are added together
(2n + 3p = 40.30)(-3)
(3n + 5p =61)(2)
-6n - 9p = -120.90
6n + 10p = 122
Step 3: add vertically
-6n - 9p = -120.90
6n + 10p = 122
p = 1.10
Step 4: Figure out the other variable by inputting the answer you just got back into the original equation
2n + 3(1.10) = 40.30
2n + 3.30 = 40.30
-3.30 37
2n = 37

n = 18.5

O a reflection of ARST across the x-axis
O a reflection of ARST across the y-axis
O a reflection of ARST across the line y = x
O a reflection of ARST across the line y=-x
Answer: D- a reflection of ^RST across the line y=-x
Step-by-step explanation:
The solution is, O a reflection of RST across the line y=-x, is the reflection which will produce an image of RST with a vertex at (2, -3).
What is reflection?Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point.
here, we have,
from the given figure,
we get,
Triangle RST has,
vertex R ( -1,3)
vertex S ( 3, -2)
vertex t (1, -4)
now we know that,
the rule of a reflection across the line y=-x,
(x, y) ⇒ (-x, -y)
so, we get, here,
vertex S ( 3, -2) ⇒ vertex at (2, -3)

Which Equation best matches the graph shown below?
Answer:
.2(x+1)(x+5)
Step-by-step explanation:
Well first lets start with the x intercepts which are -1 and negative 5 so the equation must be either -0.2(x+1)(x+5) or .2(x+1)(x+5)
Notice how the graph is going upwards this means the number in front of the equation -.2 or .2 must be positive making .2(x+1)(x+5) this is because if .2 was negative the graph would be going downwards

1. Find all the values of x ∈ {0,2π) that satisfy the equation (sen(x)-cos(x))²=1+cos(x)
Answer:
[tex]\displaystyle x=\left\{\frac{\pi}{2}, \frac{7\pi}{6}, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}[/tex]
Step-by-step explanation:
We are given the equation:
[tex](\sin(x)-\cos(x))^2=1+\cos(x)[/tex]
And we want to find all solutions for the equation within the interval [0, 2π).
First, we can expand. This yields:
[tex]\sin^2(x)-2\sin(x)\cos(x)+\cos^2(x)=1+\cos(x)[/tex]
From the Pythagorean Identity, we know that:
[tex]\sin^2(x)+\cos^2(x)=1[/tex]
Therefore:
[tex]-2\sin(x)\cos(x)+1=1+\cos(x)[/tex]
Simplify:
[tex]-2\sin(x)\cos(x)=\cos(x)[/tex]
Subtract cos(x) from both sides*:
[tex]-2\sin(x)\cos(x)-\cos(x)=0[/tex]
Factor:
[tex]\cos(x)\left(-2\sin(x)-1)=0[/tex]
Zero Product Property:
[tex]\cos(x)=0\text{ or } -2\sin(x)-1=0[/tex]
Solve for each case:
[tex]\displaystyle \cos(x)=0\text{ or } \sin(x)=-\frac{1}{2}[/tex]
Use the unit circle. So, our solutions are:
[tex]\displaystyle x=\left\{\frac{\pi}{2}, \frac{7\pi}{6}, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}[/tex]
*Note that we should not simply divide both sides by cos(x) to acquire -2sin(x) = 1. This is because we do not know what the value of x is, and so one or may values of x may result in cos(x) = 0, and we cannot divide by 0. Hence, we need to subtract and factor and utilize the Zero Product Property.

the number are going up by 4, the difference between each number is 4the first number is 15we need to fin the 73rd number, and since this pattern goes up by 4 we need to multiply 73 by 473 × 4 = 292
15 + 292 = 307 (15 is the first number we add 15 to it.)
307 - 4 = 303 (15 is the first number so we need to add 72 more places,
