Which polynomial can be factored using the binomial theorem?
100x2 + 70x + 49
100x2 + 210x + 49
1,000x3 – 2,100x2 + 1,470x – 343
1,000x3 – 2,800x2 + 1,960x – 343
Answer:C
Step-by-step explanation:
The polynomial can be factored using the binomial theorem is
1,000x³ – 2,100x² + 1,470x – 343.
What is Binomial Theorem?Assertion that the sum of the nth power of the product of two positive integers a and b may be written as the sum of the n + 1 terms of the form for any positive integer n.
If a and b are real numbers and n is a positive integer, then
[tex](a + b)^n =^nC_0 a_n + ^nC_1 a_{n-1} b_1 + ^nC_2 a_{n-2} b_2 + ... 1.[/tex]
Given:
Using Binomial we can write
(a+ b)³ = a³ + b³ + 3a²b + 3ab²
and, (a+ b)² = a² + 2ab + b²
So, 100x²+ 70x + 49 and 100x² + 210x + 49 cannot be factors using Binomial Theorem because the correct expansion would be
(10x+ 7)² = 100x² + 140x + 49
and, 1,000x³ – 2,100x² + 1,470x – 343 can be factored using Binomial theorem.
As, (10x - 7)³ = 1000x³ -2100x² + 1470x - 343.

the things in parentheses are exponents
Answer:
A laptop uses between 50 and 100 W/hour when it is being used, depending on the model. A laptop that is on for eight hours a day uses between 150 and 300 kWh and emits between 44 and 88 kg of CO2 per year. In stand-by mode the power consumption of both a desktop and a laptop falls to about a third.

R———————S——————T
The length of RS is 55 unit.
What is Axiom of addition?The addition axiom states that when two equal quantities are added to two more equal quantities, their sums are equal. Thus, if a = b and y = z, then a + y = b + z.
We have, ST = 15 and RT = 40
Then RS can be get by adding the value ST + RT.
Apply Axiom of addition
then, RS
= RT + ST
= 40 + 15
= 55 unit.
thus, the length of RS is 55 unit.

find the constant rate of change
Answer:
- 2 ft/ s
Step-by-step explanation:
The rate of change is the slope m of the line.
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 80) and (x₂, y₂ ) = (40, 0) ← 2 points on the line
m = [tex]\frac{0-80}{40-0}[/tex] = [tex]\frac{-80}{40}[/tex] = - 2
Rate of change is - 2 ft/ s

Given:
A right angled triangle.
To find:
The value of x.
Solution:
We have,
Base = x
Hypotenuse = [tex]\sqrt{5}[/tex]
In a right angle triangle,
[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]
For the given triangle,
[tex]\cos 45^\circ= \dfrac{x}{\sqrt{5}}[/tex]
[tex]\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}[/tex]
Multiply both sides by [tex]\sqrt{5}[/tex].
[tex]\dfrac{\sqrt{5}}{\sqrt{2}}= x[/tex]
[tex]\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x[/tex]
[tex]\dfrac{\sqrt{10}}{2}= x[/tex]
Therefore, the required value of x is [tex]\dfrac{\sqrt{10}}{2}[/tex].
