What are Polynomials?Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given is a cubic polynomial expression.
Given is x³ - 1.
We have to factorize it.
x³ - 1 = x³ - 1³
We have the algebraic expression identity that,
a³ - b³ = (a - b) (a² + ab + b²)
Using the expression, we get,
x³ - 1³ = (x - 1) (x² + x + 1²)
= (x - 1) (x² + x + 1)
Hence the correct form is option C.

You have 19.3 ounces of juice in a cup and pour 33.5 more ounces in the same cup. How many total ounces of juice are in the cup now?
Answer: There is 52.8 ounces of the juice in the cup now.
Step-by-step explanation:
We are given that,
The quantity of juice you initially have = 19.3 ounces
You added 33.5 ounces more to the cup.
Then, By using the addition operation, the total quantity of juice in the cup will be (Juice you initially had) + (additional amount)
i.e. The total quantity of juice in the cup= 19.3 + 33.5 ounces
The total quantity of juice in the cup= 52.8 ounces
Hence, there is 52.8 ounces of the juice in the cup now.
A cylindrical water tank has a radius of 14.5 feet and a height of 7.5 feet. Which value is the best estimate of the volume of the water tank? Round your answer to the nearest tenth of a foot.
Answer:
C= 2π14.5
C= 91.1061869
91.1061869 X 7.5 = 683.296402
A of a circle = πr squared
as the are two circles to a cylinder 2πr squared
2 X π X 14.5 = 1321.03971
add together
1321.03971 + 683.296402 = 2004.33611 ft squared

The figure shows two angles. What is the value of x?
Answer:
x=70
Step-by-step explanation:
First subtract 30 from 180
180-30=150
Subtract 10 from 150
150-10=140
Divide 140 and 2
140÷2=70
Answer:
x=70
Step-by-step explanation:
angles on a straight line add to 180
so first you do 180-30 which equals to 150
this means that 2x+10=150
take away 10 from both sides and your left with
2x=140
since you are finding x
you divide both sides by 2
x=70

Work out the circumference of this circle.
Take a to be 3.142 and give your answer to 1 decimal place.
9m
Answer:
28.3 (explaination below)! :)
Step-by-step explanation:
Use the formula for cicrumfrence: C=2πr
Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).
Plug in our numbers. C= 2π4.5
Then, multiply.
You'd get 28.27433388230814.
Rounding to the first decimal place, you'd have a final answer of 28.3.

The opposite sides of a rectangle are (2x-1)cm and (x+3)cm . if it has a perimeter of 28 cm , find the area of the rectangle
Answer: 49 square cm
======================================================
For any rectangle, the opposite sides are the same length.
Set the given expressions equal to x and solve to get
2x-1 = x+3
2x-x = 3+1
x = 4
So each opposite side is:
2x-1 = 2*4-1 = 8-1 = 7x+3 = 4+3 = 7Each side being the same length (7) confirms we have the correct x value.
------------
Let's say L = 7 is the length and W is the unknown width.
We'll use the perimeter of a rectangle formula given below with P = 28 as the given perimeter. Solve for W.
P = 2*(L+W)
28 = 2*(7+W)
28/2 = 7+W
14 = 7+W
7+W = 14
W = 14-7
W = 7
-------------
The rectangle has a length of L = 7 and width of W = 7, so its area is
A = L*W
A = 7*7
A = 49 square cm
Because we have the length and width as the same value, this rectangle is also a square.
[tex] h(t) = 8 + 40.8t -{16t}^{2} [/tex]
at what height is the ball after 2 seconds?
Step-by-step explanation:
When t = 2,
h(2) = 8 + 40.8(2) - 16(2)² = 8 + 81.6 - 64 = 25.6
Therefore the height after 2 sec is 25.6.
Answer:
[tex]h(t) = 8 + 40.8t - {16t}^{2} \\ h(2) = 8 + 40.8(2) - 16 {(2)}^{2} \\ = 8+81.6 - 64 \\ = 89.6 - 64 = \boxed{25.6}[/tex]
After 2 seconds the ball will be at the height of 25.6 unit.
