Hello from MrBillDoesMath!
Answer:
x^5 - 5 x^4 y + 10 x^3 y^2 - 10 x^2 y^3 + 5 x y^4 - y^5
Discussion:
Pascal's triangle looks like this (up to 6 rows)
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
The last row contains the constant multipliers in the equation. The terms in the expansion alternate in sign.
Thank you,
MrB
Answer:
First off there is no way this is middle school but the answer is 76
Step-by-step explanation:
84-8=76
The following is an example of a cluster sampling.
Cluster sampling<span> is a </span>sampling<span> technique used when "natural" but relatively heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this technique, the total population is divided into these groups (or </span>clusters) and a simple randomsample<span> of the groups is selected.</span>
Area=1/2 times height times base
base=2.5
area=3.75
subsitute
3.75=1/2 times height times 2.5
multiply both sides by 2 to get rid of fraction
7.5=height itmes 2.5
divide both sides by 2.5
3=height
sail is 3 meters tall
Answer:
Answer is 13x⁴ - x³ - 9x²( the last option)
Step-by-step explanation:
f(x) = 8x⁴ - x³ - 4x²
g(x) = -5x⁴ + 5x²
so,
f(x) - g(x)
=(substituting the value)
= (8x⁴ - x³ - 4x²) - (-5x⁴ + 5x²)
= 8x⁴ - x³ - 4x² + 5x⁴ - 5x²
= 8x⁴ + 5x⁴ - x³ - 4x² - 5x²
= 13x⁴ - x³ - 9x²
