Answer:
-x^4-5x^3+2x²+ 10x = (x+5)(2x-x³)
Step by Step explanation
Naming the coefficient of x² as "a" and the independent temine of the first parenthesis as "b", we got:
-x^4-5x^3+ ax^2 +10x=(x+b)(2x-x^3)
- x⁴-5x^3+ ax^2 +10x = 2x²- x⁴+2bx-bx³
-5x^3+ ax^2 +10x = -bx³+2x²+2bx
( Matching the exponents)
For x: 2b= 10; b=10/2.
b=5
For x²: a=2
For x³: -b=-5
b=5
A(n) = 1 + (n - 1)(-4.1)
a(1) = 1 + (1 - 1)(-4.1) = 1
a(4) = 1 + (4 - 1)(-4.1) = 1+(3)(-4.1)=1 - 12.3 = -11.3
a(10) = 1 + (10 - 1)(-4.1) = 1 + (9)(-4.1) = 1 - 36.9 = -35.9
Answer:
you can not call it domain cause it is only an expression not equation
you have to exclude 0 from domain
Step-by-step explanation:
Area of circle = πr²
Given that area = 153.86 m², find the radius:
153.86 = πr²
r² = 153.86 ÷ π
r² = 48.98
r = √48.98
r = 7 m
Diameter = Radius x 2 = 7 x 2 = 14 m
Answer: Diameter = 14 m
Step-by-step explanation:
0.6m×0.8
=0.48m²
