Checking for a perfect cube :
3.1 3m3 + 5m2 - 5m + 1 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 3m3 + 5m2 - 5m + 1
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -5m + 1
Group 2: 5m2 + 3m3
Pull out from each group separately :
Group 1: (-5m + 1) • (1) = (5m - 1) • (-1)
Group 2: (3m + 5) • (m2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
Polynomial Roots Calculator :
3.3 Find roots (zeroes) of : F(m) = 3m3 + 5m2 - 5m + 1
Polynomial Roots Calculator is a set of methods aimed at finding values of m for which F(m)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers m which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 3 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,3
of the Trailing Constant : 1
Let us test ....
P Q P/Q F(P/Q) Divisor

-1 3 -0.33 3.11
1 1 1.00 4.00
1 3 0.33 0.00 3m - 1
The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms
In our case this means that
3m3 + 5m2 - 5m + 1
can be divided with 3m - 1
Polynomial Long Division :
3.4 Polynomial Long Division
Dividing : 3m3 + 5m2 - 5m + 1

By : 3m - 1 ("Divisor")
dividend 3m3 + 5m2 - 5m + 1
- divisor * m2 3m3 - m2
remainder 6m2 - 5m + 1
- divisor * 2m1 6m2 - 2m
remainder - 3m + 1
- divisor * -m0 - 3m + 1
remainder 0
Quotient : m2+2m-1 Remainder: 0
Trying to factor by splitting the middle term
3.5 Factoring m2+2m-1
The first term is, m2 its coefficient is 1 .
The middle term is, +2m its coefficient is 2 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is 2 .
-1 + 1 = 0
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Rewrite the whole as a fraction using 3 as the denominator :
1 1 • 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
5.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Bridget, Brian & Caroline share some money in the ratio 4 : 9 : 4.
In total, Bridget and Caroline receive £48.
How much does Brian get?
Answer:
the answer is 54
Step-by-step explanation:
48 / 4 is 12, so then divide that by 2 so they split equally because theirs combined added to 48, so 6.
6 * 9 is 54

Based on the given figure, determine the angles that show congruent alternate exterior angles
Answer:
Angle 1 and angle 8
Angle 2 and angle 7
Step-by-step explanation:
Alternate exterior angles are angles positioned alternating each other along the transversal, where both angles are found outside the two parallel lines cut across by the transversal.
Thus from the diagram given, the following are alternate exterior angles that are congruent:
Angle 1 and angle 8
Angle 2 and angle 7

44. Find the arc length on a circle with radius =5 inches and a central angle of pi/3 help plsss
Answer:
Step-by-step explanation:
Because your angle is in radians, I'm assuming we can use the pre-calculus version of the arc length formula which is
s = rt where s is the arc length, r is radians, and t is the angle in radian measure. Filling in accordingly:
[tex]s=5(\frac{\pi}{3})[/tex] so
[tex]s=\frac{5\pi}{3}[/tex] inches

0.14 quarts to 0.24 quarts
Enter the ratio as a fraction of whole number in lowest tents ( no decimals )
Answer: [tex]\dfrac{7}{12}[/tex] .
Step-by-step explanation:
To find : Ratio of 0.14 quarts to 0.24 quarts.
In fraction it will be
[tex]\dfrac{\text{0.14 quarts}}{\text{0.24 quarts}}\\\\=\dfrac{14}{24}\ \ \ \ \\\\=\dfrac{7}{12}\ \ \ \ \ [\text{Divide numerator and denominator by 2}][/tex]
= 7:12

Three students Tahat, Promi and Kabi, Appeared at an examination. Promi secured 11 marks less than Tahat, 5 marks more than kabi and again. Tahat's marks were 75% of the sum of Promi and Kabi's marks. Find out their individual marks
Answer: Tahat= 40.5 marks Promi =29.5 marks, Kabi =24.5 marks
Step-by-step explanation:
Step 1
Let the marks be represented as x+11, x and x-5 for Tahat, Promi and Kabi respectively
and Tahat's marks which was 75% of the sum of Promi and Kabi's marks be expressed as
x+11 = 75/100(x + x-5)
Step 2 --- Solving
x+11 = 75/100(x + x-5)
x+ 11 = 3/4(2x-5)
x+11= 6x-15/4
4x+44=6x-15
44+15=2x
x= 59/2= 29.5,
A) x= Promi's mark was 29.5
B)Promi secured 5 marks more than kabi
Therefore, Kabi's mark was 5 marks less than Promi
= x-5
29.5- 5= 24.5 marks
C)Promi secured 11 marks less than Tahat, Therefore Tahat marks were 11 marks more than Promi
x+11= 29.5 + 11= 40.5

-4+5y= 13
X-5y=21
( , )
Answer:
y=17/5 ,x= 38
Step-by-step explanation:
-4+5y =13 add 4 both side
4-4+5y=13+4
5y=17
5y/5=17/5 y=17/5
x-5y=21
x-5(17/5)=21
x-17=21
x=21+17= 38

An electrician charges an initial fee of $35 for attending a house call. Thereafter, he charges $15 for every hour spent on the job. The equation for this is represented = 35 + 15, where $Y represents the charges the house owner has to pay and is the number of hours the electrician spends on the job: (a) , find the amount of money the house owner needs to pay if he spends (i) 1 hour (ii) 2 hours (iii) 3 hours (iv) 4 hours on the job very urgent
Answer:
1 hour=35+15=50
2 hours=35+15(2)=65
3 hours=35+15(3)=80
4 hours=35+15(4)=95

Answer:
y = 3x
Step-by-step explanation:
This is dealing with slope so think of it as rise over run
[tex]\frac{Rise}{Run}[/tex]
The y intercept is a 0 so you don't have to worry about adding a number after the plus symbol. You can if you want but that's not an option. You go up 3 over 1 and then you get to your next point.
