Answer:
Step-by-step explanation:"
The electrician charges an initial fee of $42", AND "The electrician charges $22 for every hour worked" is true.
The equation is y=22x+42. The formula is y=mx+b.m is the slope, or is this case, the number of dollars for every "x", which is the number of hours worked. So you have to pay $22 for every hour the electrician works.b is the y-intercept, or the amount it starts with, in this case, you have to pay a fee of $42 even when the electrician worked 0 hours. This is because $42 is the amount it starts with.On a graph, the line will start at (0,42) because that is when you start paying. And then it will increase by 22 for each hour, so the next coordinate would be (1,64).
The given function y=22x+42 represents the electrician’s charges. The electrician charges $22 for each hour worked and has a flat service fee of $42.
Explanation:
The given function y=22x+42 stands for the electrical work charges in terms of hours worked. Here 'y' represents the total amount charged, 'x' represents the number of hours worked, '22' is the hourly rate and '42' is likely a fixed service fee regardless of the hours worked. So the aspects that holds true for this function are: (1) The electrician charges $22 per hour of work, (2) The electrician has a fixed service fee of $42 whether or not they have worked any hours

Which of the following represents a function?
Answer:
Option D. is the answer.
Step-by-step explanation:
Option A.
From the table we can see that for the value of x = 3, there are two values of y (14 and 19).
Which is not possible for a function. It should be one to one.
So option A is not a function.
Option B.
In this option again we have two values of y = 0, -5 for the value of x = 3.
For a function values of x and y should be one to one.
Therefore, it's not a function.
Option C.
Here for x = -1, there are two values of y (y = -11 and 5).
Therefore, it's not a function.
Option D.
In the given graph we find that there are different values of y for every value of x.
Therefore, Option D is the answer.
Which polynomial could have the following graph?
y = (x + 3)(x - 1)(x - 5)
y = (x - 3)(x + 1)(x + 5)
y = -(x + 3)(x - 1)(x - 5)
y = -(x - 3)(x + 1)(x + 5)
The graph shows the solutions:
x1 = -3 ⇒ x + 3 = 0
x2 = 1 ⇒ x - 1 = 0
x3 = 5 ⇒ x - 5 = 0
The polynomial follows: y = (x + 3)(x - 1)(x - 5)
.
Answer:
y= (x+3) (x-1) (x-5)
Step-by-step explanation:
The graph crosses the x axis at the points -3,1,5
These are also called the zeros
f(x) =k (x-a) (x-b) (x-c) .....
where a,b,c,... are the zeros of the function and k is a constant
f(x) = k * (x--3) (x-1) (x-5)
f(x) = k(x+3) (x-1) (x-5)
To help determine the value of k
Take another point at x = 0, we know the value is positive
f(0) = k(3) (-1) (-5)
f(0) = k(15)
That means k must be greater than 0 Looking at the graph, it should be around 1
f(x) = (x+3) (x-1) (x-5)

f(x)=25x^2-10x+1
what is the value of the discriminant of f?
how many x-intercepts does the graph of f have?
The discriminant of the quadratic function f(x) = 25x² - 10x + 1 is equal to zero. Hence, the graph of this function has only one x-intercept.
Explanation:The student is asking for the value of the discriminant of the quadratic function f(x) = 25x² - 10x + 1 and the number of x-intercepts the function has. In a quadratic function ax²+bx+c, the value of the discriminant, denoted as D, is calculated using the formula D = b² - 4ac. In this case, a = 25, b = -10, and c = 1.
Therefore, the discriminant D = (-10)² - 4(.25)(1) = 100 - 100 = 0. The quadratic equation will have exactly one root if the discriminant is zero.
Thus, "the graph of the function f(x) = 25x² - 10x + 1 has one x-intercept".

What is the end behavior of the graph of the polynomial function y = 10x9 – 4x?
The end behavior of the function y = 10x9 – 4x is such that as x approaches infinity, y approaches infinity, and as x approaches negative infinity, y approaches negative infinity. This is because the degree of the polynomial is odd and the leading coefficient is positive.
Explanation:The end behavior of a polynomial function describes what happens to the function values (y-values) as x approaches infinity and negative infinity. In your function, y = 10x9 – 4x, the highest power of x is 9, and it's coefficient is positive.
According to the rules of end behavior, if the degree (highest power) of the polynomial is odd, and the leading coefficient (the number in front of the highest power) is positive, as x approaches positive infinity, y also approaches positive infinity, and as x approaches negative infinity, y approaches negative infinity.
In simpler terms, this means that the graph of your function starts in the third quadrant (bottom-left) and ends in the first quadrant (top-right). Hence, the end behavior of this function can be described as: as x approaches infinity, y approaches infinity; and as x approaches negative infinity, y approaches negative infinity.

As the sample space is for first rolling a number cube and then shooting a basketball, it should be a number n , and X/O
where n= 1,2,3,4,5,6
of the given options
A) 0,2 is incorrect as O of basketball is first and then there is 2

B) X,O is incorrect because both are from shooting basket ball
C)1,T is incorrect as T is not from the basketball.
only D is correct 6,X!
Option D.) 6, X correctly represents an element of the sample space for rolling a number cube followed by shooting a basketball, including an outcome of rolling a 6 and then making the shot
The question relates to an understanding of sample spaces in probability. The sample space is a set of all possible outcomes of a probability experiment. In this case, the experiment consists of two independent actions: rolling a number cube (commonly a six-sided die) and shooting a basketball with two possible outcomes (making a shot 'X' or missing 'O').
A correct element of the sample space would include one outcome from rolling the die (1 through 6) and one outcome from shooting the basketball (X or O). For example, rolling a 1 on the die and making the basketball shot (X) would be represented as (1, X). Therefore, the correct answer to the question is option D.) 6, X, which shows an outcome of rolling a 6 on the die followed by making the basketball shot

Step-by-step explanation:
On square roots you have to make sure the inside is positive or zero.
So the domain of the first one will come from solving
[tex]6-2x \ge 0[/tex]
Subtract 6 on both sides:
[tex]-2x \ge -6[/tex]
Divide both sides by -2 (flip inequality when divide both sides by negative):
[tex]x \le 3[/tex]
The domain is less than or equal to 3.
Interval notation [tex](-\infty,3][/tex]
On fractions you have to watch out for dividing by 0.
The domain is all real numbers except when 4x+2=0.
4x+2=0
Subtract 2 on both sides:

Mary, Kevin, and Ahmad served a total of 126
orders Monday at the school cafeteria. Kevin served 6
more orders than Mary. Ahmad served 4
times as many orders as Kevin. How many orders did they each serve?
Answer:
Mary: 16
Kevin: 22
Ahmed: 88
Step-by-step explanation:
This could be written as the following formula.
Mary + Kevin + Ahmad = 126
and we know that
Mary + 6 = Kevin
Kevin * 4 = Ahmed
so Ahmed = (Mary + 6) * 4
When filling this in you get
Mary + Mary + 6 + (Mary + 6) * 4 = 126
Mary + Mary + 6 + 4Mary + 24 = 126
6Mary + 30 = 126
6Mary = 96
Mary = 16
So Mary served 16 orders.
Using the earlier formulas you get
Kevin = Mary + 6 = 16 + 6 = 22
Ahmed = Kevin * 4 = 22 * 4 = 88.
Now we just need to double check it.
Mary + Kevin + Ahmad = 16 + 22 + 88 = 126. Which matches what it should be.

Answer:
answer: 5x + 10
Step-by-step explanation:
The distributive property (of which this is an example) demands that the 5 must multiply the x (which was done correctly) to give 5x
But the problem becomes undone when you forget about the 2. You must multiply the 2 by 5 as well to give 10.
The plus sign cannot be destroyed. The terms are not alike. So the answer is 5x + 10
Organizing a data set allows you to do each of the following except:
A. see important values in the data set
B. take up less space than when the data set is not organized
C. more easily see the maximum and minimum values in the data set
D. see if any data values are much larger or much smaller than other data values
Answer:
B. take up less space than when the data set is not organized
Step-by-step explanation:
Well, in this question, you can analyze one answer after the other.
In A see important values in the data set, this makes sense when determining mode and median of a data set.Median is the center value in a data set, while mode is the repeated value in the set.When data set is arranged from smallest to the largest, the median and mode can be seen clearly.These can be the important values in the data set
In C. More easily see the maximum and minimum values in the data set, is possible especially when data is arranged in an increasing order.The smallest value will start, where as the largest value will be at the end.This applies to D too.
However in B, it will depend with the manner you would like to analyze the data.For example organizing data using tables will make your data easy to understand and present your analysis.Another person will group the data in intervals to identify the frequency of in data set.So, you see, its not about space taken by data but how you would like to present your data when analyzing it.

The difference of two numbers is 7. If the sum of the smaller number and the square of the larger number is 125, what is the larger number?
Step-by-step explanation:
x - y = 7...eqn 1
x^2 + y = 125...eqn 2
making y the subject of the formula in eqn 1
=> y = x -7...eqn 3
subst for y from eqn 3 in eqn 2
=> x^2 + x-7 = 125
=> x^2 + x - 132 = 0
=> (x + 12) (x -11) =0
x = 11 or -12
when x = 11, y = 4
when x = -12, y = -19
Answer:
The largest numbers is either -12 or 11
Step-by-step explanation:
Let the numbers be a and b and a be the largest number.
The difference of two numbers is 7
a - b = 7 ------------------------- eqn 1
The sum of the smaller number and the square of the larger number is 125
a² + b = 125 ------------------------- eqn 2
eqn 1 + eqn 2
a² + a - 132 = 0
( a + 12 ) (a - 11) = 0
a = -12 or a = 11
So the largest numbers is either -12 or 11

Select one:
a. 435.4
b. 51.4
C. 311.08
d. 874.94
The sum of the geometric series is approximately 435.4, according to the formula for geometric series summation.
To find the sum (Sn) of a geometric series, you can use the formula:
[tex]\[ Sn = \frac{{a_1 \cdot (1 - r^n)}}{{1 - r}} \][/tex]
Where:
[tex]- \( a_1 \) is the first term\\- \( r \) is the common ratio\\- \( n \) is the number of terms[/tex]
Given:
[tex]\( a_1 = 0.28 \)\( a_5 = 362.88 \)\( r = 6 \)[/tex]
We need to find [tex]\( n \)[/tex]. Since [tex]\( a_5 \)[/tex] is the fifth term, we can use the formula for the nth term of a geometric series:
[tex]\[ a_n = a_1 \cdot r^{(n-1)} \][/tex]
Substitute the values we have:
[tex]\[ 362.88 = 0.28 \cdot 6^{(5-1)} \]\[ 362.88 = 0.28 \cdot 6^4 \]\[ 362.88 = 0.28 \cdot 1296 \]\[ 362.88 = 363.648 \][/tex]
So, [tex]\( n = 5 \).[/tex]
Now, plug the values into the sum formula:
[tex]\[ S_5 = \frac{{0.28 \cdot (1 - 6^5)}}{{1 - 6}} \]\[ S_5 = \frac{{0.28 \cdot (1 - 7776)}}{{-5}} \]\[ S_5 = \frac{{0.28 \cdot (-7775)}}{{-5}} \]\[ S_5 = \frac{{-2177}}{{5}} \]\[ S_5 = -435.4 \][/tex]
Since the sum of a series cannot be negative, the correct answer is option:

A squirrel is looking up to the top of a tree at a 35∘ angle of elevation. The squirrel to the base of the tree is 47 feet. Find the height of the tree. Round your answer to the nearest foot. The height of the tree is about feet.
Answer:
33 feet
Step-by-step explanation:
We can draw a triangle in this situation.
Note:
The height of the tree is the side "opposite" of the 35 angle. The squirrel's distance of 47 feet from the base of the tree is the side "adjacent" to the angle.
Which trig ratio relates "opposite" and "adjacent"?
It is Tan
Thus we can write and solve (let height of tree be h):

To the nearest foot, the height of tree is about 33 feet
if m<1=40 and m<2=80, what is m<3?
Answer:
60 degrees, 55 degrees, and 50 degrees respectively
Step-by-step explanation:
Equation: m<1+m<2+m<3=180
1. 40+80+x=180 Subtract 120(because 40+80=120)

What is the measure of angle BCD? 25 40 140 155
Answer:155
Step-by-step explanation:
The measure of angle BCD is 140°.
Quadrilaterals
Quadrilaterals are geometric figures with 4 sides and 4 angles. And, for these figures, the sum of interior angles is 360°. There are different types of quadrilaterals, for example, square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles.
Supplementary AnglesSupplementary angles are two angles whose sum is equal to 180°.
For solving this question, you should find the supplementary angle for A, B and D angles.
Angle A A+25=180A=180-25=155°
Angle BB+146=180
B=180-146=34°
Angle DD+149=180
B=180-149=31°
After that, find the angle C from a property of quadrilaterals - sum of interior angles is 360°. Thus,
A+B+C+D=360
155+34+C+31=360
C=360-31-34-155
C=140°.
