Answer: A polynomial is an expression with variables and coefficients separated by addition and subtraction. The following are used when determining if an expression is a polynomial:
i) Variables of a polynomial must not have negative exponent.
ii) Variables of a polynomial must not have fractional exponent.
iii) Dividing by an exponent is not allowed
iv) Exponent radicals are not allowed.
a) [tex]3m^2n-\frac{2m}{n}+\frac{1}{n}[/tex] is not a polynomial because dividing by an exponent is not allowed.
b) [tex]\frac{2mn}{5}-\frac{\sqrt{m} }{4} +4m^5[/tex], is not a polynomial because exponent radicals are not allowed (√m)
c) [tex]\frac{4m^3}{n^2}-3mn^5+\sqrt{8}[/tex] is not a polynomial because dividing by an exponent is not allowed.

Answer:
This is a geometric sequence and the common ratio is equal to ½.
Step-by-step explanation:
For a sequence to be termed to be in arithmetic progression, the difference between consecutive terms are the same and constant.
On the other hand, a sequence is termed to be in geometric progression if the ratio of a term to the term before it is the same as the ratio between the next term to it.
Let's consider the sequence given: 12, 6, 3 . . .
=>Let's try to find the common difference if it would be constant: 6-12 (-6) ≠ 3-6 (-3)
The sequence is not arithmetic.
=>Let's also try to find the ratio of the sequence to see if it is constant:
6/12 (½) = 3/6 (½)
Therefore we can conclude the sequence is geometric because the common ratio (½) is constant.
This is a geometric sequence and the common ratio is equal to ½.

Angle JKL is a right angle. The measure of the angle JKM is 65. The measure of angle MKL is x . What is the value of x?
Answer:
25
Step-by-step explanation:
angle JKM and Angle MKL are supplementary. means, they add to 90degree. So to fing the missing one, just do 90 - 65. you'll get 25.
The angle MKL is equal to 155 which corresponds to the value of x=155.
What is right angle?
The angle equal to 90 degree is called right angle and the triangle in which one angle is equal to 90 is called right angled triangle.
How to find the value of one angle when the value of two angle is given?In the figure we can see that the value of angle JKL is equal to 90, value of angle JKM is 65 and we have been given that angle MKL is equal to x.
From the figure we can see that,
MKL=JKL+JKM
=90+65
=155 degree
Hence the value of x is equal to 155 degree.

Answer:
See below.
Step-by-step explanation:
1. x = e^(x/y) Taking logs:
log x = x/y
x = y log x
Differentiating:
1 = dy/dx log x + y * 1/x
dy/dx log x = (1 - y/x)
dy/dx = (1 - y/x) / log x
dy/dx = ((x - y)/ x) / log x
dy/dx = (x - y) / x log x)
2. y^x = e ^(y - x)
Taking logs:
x log y = y - x --------------(A)
y = x + x logy --------------(B)
dy/dx = 1 + x * 1/y * dy/dx + 1*logy
dy/dx - dy/dx * x/y = 1 + log y
dy/dx ( (x - y) y)) = 1 + log y
dy/dx = y(1 + log y) / (y - x)
Using (A) and (B) :-
dy/dx = x(1 + logy)(1 + logy) / x logy The x's cancel, so:
dy/dx = (1 + logy)^2 / log y

Can a function have a repeating input
Answer: It Depends
Explanation: Generally, your answer would be no because if you have a repeating input, you usually have a different output for that specific repeating input which would not make it a function.
However, a function can have a repeating input if the same input is paired with the same output and this is listed twice so it's still a function since each input pairs with a unique output.
However, if the input appears more than once, you must check to see whether the output is the same or different.

mr rai bys a radio for rs 1880ans sell it to mr Sherpa at 20 percent .how much money does he pay for it
Answer:
Rs 1504
Step-by-step explanation:
Mr. Rai buys for Rs 1880.
He sells it to Mr. Sherpa at 20% discount.
1880 × 20%
= 376
1880 - 376
= 1504
Mr. Sherpa buys it for Rs 1504.
Answer:
Mr. Rai will be receiving $1504 if he sells the radio for 20%.
Step-by-step explanation:
To find a discount, move the decimal over twice on the percentage. After doing this, multiply that number by the original number. You will get a new number. Subtract the price by the new number and there is your answer.
For Example:
20% = .20
1880*.20= 376
1880-376= 1504
There is a simpler way of doing this as well. Multiplying by .8 (which is the remainder of 100% after taking away 20% if this makes sense) will give you the answer immediately. Hopefully this helps.
Good luck!

Mr. Ferrier invested $26,000. Some was invested in bonds that made a 5% profit, and the rest was put in stocks that made an 8% profit. How much did mr. Ferrier invest in bonds if his total profit on both types of investments was $1,420
Answer:
bonds=22000
stock=4000
Step-by-step explanation:
let b for bonds , and s for stock
b+s=26000
0.05 b +0.08 s=1420
to solve (by elimination)
1- multiply first equation with 0.05 to eliminate b
0.05 b+0.05 s=1300
0.05b+0.08s=1420
subtract two equations:
0.05b+0.05s-0.05b-0.08s=1300-1420
-0.03s=-120
s=120/0.03=4000
b+s=26000
b=26000-4000=22000
check:0.05(22000)+0.08(4000)=1420
Answer:
$22000
Step-by-step explanation:
x*0.05+(26000-x)*0.08= 1420
0.05x - 0.08x + 2080= 1420
0.03x=2080 -1420
0.03x= 660
x= 660/0.03
x= 22000
$22000 = 5% bonds
$4000 = 8% stocks

In a school of 685 students, there are 385 students involved in sports teams, and there are
450 involved with the music program. There are 87 students that are not involved in either
program. There are some students involved in both programs.
a) Draw a Venn diagram to represent this situation.
b) Use the additive principle of non-mutually exclusive sets to determine the number of
students that are involved in both team sports and music
C) use the addictive principle for the probability of non-mutually exclusive events to determine the probability of a student being involved in team sports or involved in music
Answer:
A) check attached picture
B) 272
C) 0.4478
Step-by-step explanation:
From the information given ;
A) The Venn diagram of the information can be found in the attached picture.
B) Number of students involved in both team sports and music.
n(student in sports team) = 385
n(students involved in music) = 450
Number of students involved in both music and team sport = y
Number of students not involved in either team sport or music = 87
Total number of students = 650
Therefore,
n(music alone) = 450 - y
n(team sport alone) = 385 - y
Adding the following:
n(music alone) + n(team sport alone) + n( both music and team sport) + n(neither music nor team sport) = Total number of students
450 - y + 385 - y + y + 87 = 650
922 - y = 650
922 - 650 = y
y = 272
Therefore, number of students involved in both music and team sport = 272
C) probability of being involved in team sport or in music.
P(being involved in music) = (450 - 272) / 650 = 0.2738
P(being involved in team sport) = (385 - 272) / 650 = 0.1738
P(involved in both) = 272 / 650 = 0.4184
P(involved in neither) = 87 / 650 = 0.1338
P(being involved in team sport) or p(being involved in music)
P(being involved in team sport) + p(being involved in music)
0.1738 + 0.2738 = 0.4478

We have 2 clusters of angles here: one with S in the middle and one with P in the middle. Corresponding angles means that within each cluster, 2 angles are sitting in the same position, one in each cluster. Angle QPN is corresponding to angle TSP because both of the angles are sitting below line UN, and each is sitting to the right of its transversal.

A 2 by 3 rectangle contains 8 squares. A 3 by 4 rectangle contains 20 squares. A 4 by 6 rectangle contains 50 squares. What size rectangle contains exactly 100 squares? Is there more than one? Can you find them all? Can you prove there are no more?
Answer:
The rectangles that have exactly 100 squares are 1 by 100 4 by 11 and 5 by 8
Step-by-step explanation:
The given parameters are;
A 2 by 3 rectangle contains 8 squares
A 3 by 4 rectangle contains 20 squares
A 4 by 6 rectangle contains 50 squares
We note that the number of squares varies proportionately to the increase in the dimension of the rectangle, that is we have;
2 by 3 rectangle contains 8 squares
3 by 4 rectangle contains 20 squares increase by 12 = 3 × 4
4 by 5 rectangle contains 40 squares increase by 20 = 4 × 5
The number of squares formed can therefore be arranged in a matrix as follows(please see attached matrix);
Column, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
Row
1
2
3
4
5
6
7
8
9
10
11
It will be observed that after reaching a point where the row and column are equal, (x, x) the rate of increase in the number of squares become constant and equal to x × ((x - 1) × 0.5) + 1) = x × (x + 1)/2
From the matrix, the rectangles that have exactly 100 squares are 1 by 100 4 by 11 and 5 by 8 and there are no more as presented in the attached matrix, the number of squares formed keeps increasing for each column and row added.

A soccer team scores 12 points in 5 matches. They scored the same number of points in each of their first 3 matches and one more point in each of their last 2. How many points did they score in each match?
Answer:
2 points the first 3 matches then 3 points the last 2 matches
Step-by-step explanation:
12 points in 5 matches and the first 3 are all the same then the other 2 increased by 1 point
They got 2 points the first 3 matches then 3 points the last 2 matches
2 + 2 + 2 (first 3 matches) = 6
3 + 3 (last 2 matches) = 6
6 + 6 = 12

What is the multiple zero and multiplicity of f(x) = (x – 1)(x – 1)(x + 7)?
The zeroes of the function are 1 and 7 and multiplicity for zero 1 is two and for zero 5 is one.
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have a polynomial function:
f(x) = (x – 1)(x – 1)(x + 7)
We can write it as:
f(x) = (x – 1)²(x + 7)
Here at x = 1 the given function becomes zero and (x-1) repeats two times, so the multiplicity is 2, and for x = -7 the multiplicity is 1.
Thus, the zeroes of the function are 1 and 7 and multiplicity for zero 1 is two and for zero 5 is one.
