Lets assume that the input values are x values and the output values are y values.
Then you will have pairs of coordinate values as shown;
(-1,7) , (0,2) , (1,-3) , (2,-8), (3,-13), (4,-18)
Using the coordinates find the slope a;
(-1,7) and (0,2) ---------slope is change in y-values/ change in x-values , (2-7) /(0--1)
= -5/ 1 = -5
Do the same for the next pair of coordinates ,(0,2) and (1,-3) , (-3-2) / (1-0) = -5/1 = -5
If you continue the procedure to the next pair which is (1,-3) and (2,-8) to get the slope as : (-8- -3) / (2-1) = -5/1 = -5
This means that the slope is -5
The relation will be represented by the equation y= mx + c where m is the slope and c is the y-intercept
First plot the points to visualize the graph
From the plot, you notice that when the points are joined, a straight graph is formed sloping to the negative side and intersecting the y-axis at point (0,2).
So to determine the rule, we apply the equation y= mx + c with m= -5 and c =2
This gives y= -5 x + 2
The rule is f(x) = -5x +2 -----------answer

Step-by-step explanation:
"with replacement" is important.
that means that the mixture of the marbles and therefore the chances to pull certain marbles does not change with the previous pull.
a probability is always
desired cases / totally possible cases
we have 14 marbles in the bag
4 orange
2 green
8 purple
the probability to pull an orange marble is therefore
4/14 = 2/7
the probability to pull a green marble is therefore
2/14 = 1/7
the probability to pull a purple marble is therefore
8/14 = 4/7
a.
a green marble is pulled AND then a purple marble is selected.
we need to combine both probabilities for one combined event :
1/7 × 4/7 = 4/49
b.
a purple marble and then a green marble is selected.
4/7 × 1/7 = 4/49
since we replace the marbles after every pull, both probabilities are the same, of course.
every pull has the same probability for each desired event.
c.
2 orange marbles are selected.
2/7 × 2/7 = 4/49
d.
2 non-orange marbles are pulled
there are 10 non-orange marbles. so this is
10/14 × 10/14 = 5/7 × 5/7 = 25/49

Answers
The given group of equations represents a system of non-linear equations.
How to know if an equation is linear or nonlinear?A mathematical equation must take the form y = m x +b in order to be classified as a linear function (in which m is the slope and b is the y-intercept). This form cannot be satisfied by a nonlinear function.
Only first degree variables and terms that contain the products of variables are present in a linear equation.
However, in the case of nonlinear equations, either the equation comprises a product of variables or at least one of the variables is not of the first degree.
If the graph of an equation is a straight line, the equation is linear. Otherwise, if the power of x is more than one, then it is nonlinear.
The given equations has the degree more than 1 and their graph is also not a straight line.
Hence, the given group of equations represents a system of non-linear equations.

Lynn Golding is employed as a payroll supervisor and earns $18 per hour. This pay period she worked 40 hours. She is married and claims 6 allowances. The state tax is 3.0% of gross earnings, and the local tax is 1.5% of gross earnings. Lynn pays $35 for medical insurance and $17 in union dues. Calculate Gross pay, net pay, federal income tax, social security, Medicare, State, Local, Medical and Union Dues.
Answers
The earnings and deductions, are given as follows:
Gross pay: $720.Net pay: $498.07.Federal income tax: $82.45.Social security tax: $44.64.Medicare tax: $10.44.State tax: $21.60.Local tax: $10.80.Medical due: $35.Union due: $17.What are her earnings and deductions?First we find her gross earning, which is given by the hourly wage multiplied by the number of hours worked, hence:
Gross pay = 40 x 18 = $720.
Hence her yearly income is given by:
Yearly income = 52 x 720 = $37440.
Meaning that her federal tax rate is of $19.76 a week plus 12% of the excess over $197.60, then:
Federal tax = 19.76 + 0.12 x (720 - 197.60) = $82.45.
The social security tax rate is of 6.2% of her gross weekly earnings, hence it is given by:
Social Security = 0.062 x 720 = $44.64.
The medicare tax rate is of 1.45% for Lynn(employee), hence:
Medicare = 0.0145 x 720 = $10.44.
The state tax is 3% of her gross earnings, hence:
State tax = 0.03 x 720 = $21.60.
The local tax is 1.5% of her gross earnings, hence:
State tax = 0.015 x 720 = $10.80.
The medical and union dues are stated in the problem, hence the sum of all discounts is given by:
82.45 + 44.64 + 10.44 + 21.60 + 10.80 + 35 + 17 = $221.93.
The net pay is the gross pay subtracted by the discounts, hence:
Net pay = 720 - 221.93 = $498.07.
Missing informationThe value of an allowance is not stated, hence they are not considered for the calculations.

How to find the inverse of a function?To find the inverse of a function, we exchange x and y in the original function, then isolate y.
This means that if the original function has a point (x,y) graphed, the inverse will have point (y,x) graphed.
From it's graph, the function h(x) has these two following points:

b) 0.00604
c) 2.4 * 10^6
d) 1.47 * 10^(-3)
===================================================
Explanation:
The exponent over the 10 tells us how many spaces to move right or left. If the exponent is positive, we move right. If negative, we move left. Think of a number line.
For part (a), the exponent is 4. So we move the decimal point 4 spaces to the right.
The 3.25 then becomes 32500
--------------
In part (b), the exponent -3 means we move 3 spots to the left to go from 6.04 to 0.00604
---------------
Part (c)
Place the decimal point between the first two digits and erase the zeros to get 2.4
Then we need to move the decimal point 6 spots to the right to get back to 2,400,000 again
Therefore we can say 2,400,000 = 2.4*10^6
---------------
Part (d)
Place the decimal point just after the first nonzero digit, and erase the zeros to the left to get 1.47
We must move the decimal point 3 spots to the left to go from 1.47 back to 0.00147 again
It means 0.00147 = 1.47*10^(-3)

What is interquartile range?When values are ranked from lowest to highest, the IQR designates the middle 50% of those values. Find the median (middle value) of the bottom half and upper half of the data before calculating the interquartile range (IQR). Quartile 1 (Q1) and Quartile 3 are these values (Q3). The IQR represents the variation between Q3 and Q1. The strongest indicator of variability in data sets with outliers or skewed distributions is the interquartile range. It's unlikely to be impacted by outliers because it's based on numbers that come from the center half of the distribution.

suppse that you buy and exerice ball with diameter of 85 cm and your brother buys and exercise ball with 65 cm what is the diffrence bewtween the volume and surface are of both balls? round to the nearest 100
Answers
Given:
• Diameter of my ball = 85 cm
• Diameter of my brother's ball = 65 cm
Let's find the difference between the volume of the both balls and also let's find the difference between the surface area of both balls.
A ball has the shape of a sphere.
Therefore, we have the following formulas:
• Volume of a sphere formula:
[tex]V=\frac{\pi d^3}{6}[/tex]• Surface area of a sphere formula:
[tex]A=\pi d^2[/tex]Where d is the diameter.
• Now, to find the difference between the volume of both balls, we have:
[tex]V_1=\frac{\pi d^3}{6}=\frac{\pi85^3}{6}=321555.09\approx321555\text{ cm}^3[/tex]The volume of my ball is 321555 cubic cm.
[tex]V_2=\frac{\pi *65^3}{6}=143793.3\approx143793\text{ cm}^3[/tex]Volume of my brother's ball is 143793 cubic cm.
Therefore, to find the difference between the volume of both balls, we have:
V = V1 - V2 = 321555 - 143793 = 177762 cm³ = 177800 cm³
The difference between the volume of both balls is 177800 cm³
• Now for the surface area, we have:
[tex]A_1=\pi d^2=\pi *85^2=22698.01=22698\text{ cm}^2[/tex]The surface area of my ball is 22698 cm²
For surface area of my brother's ball:
[tex]A_2=\pi d^2=\pi *65^2=13273.23\approx13273\text{ cm}^2[/tex]The surface area of my brother's ball is 13273 cm².
Difference of surface areas:
A = A1 - A2 = 22698 - 13273 = 9425 cm² = 9400 cm²
Therefore, the difference between the surface area of both balls is 940O cm².
ANSWER:
• Difference between volume of both balls= 177800 cm³
• Difference between the surface area of both balls = 9400 cm²

Answer:
(b) 4.65×10⁹
Step-by-step explanation:
You want 4,650,000,000 written in scientific notation.
Scientific NotationA number is written in scientific notation in the form shown in the second attachment. The coefficient has one digit to the left of the decimal point. The remaining significant digits of the number are to the right of the decimal point.
The exponent is the same as the exponent of the place value of the most significant digit of the number. Some of those exponents are shown in the first attachment.
ApplicationThe given number has its most significant digit (4) in the "billions" place. The corresponding exponent of 10 is 9. Putting 4 to the left of the decimal point, the number is written in scientific notation as ...
4.65×10⁹

Additional comment
In the above, we have used the superscript font to indicate the exponent. In plain text, an exponent is indicated with a caret (^), as in 4.65·10^9.
If you use an "x" character for a multiplication symbol, you need to make sure it cannot be confused with a variable named "x".
In spreadsheets and some calculators, the base and exponent are written as "E". Here, the number would be 4.65E9. (This is a carryover from one of the earliest high-level computer programming languages.)
(You will notice that the number in the second attachment is similar to, but not the same as, the one given in this problem statement. We intend that attachment to show the format, not the answer to this question.)
