Answer:
Example: <em>- 2x³ + 10x²</em>
Step-by-step explanation:
1.<em>A cubic function</em> is a polynomial of degree 3 in one variable. This means that the highest exponent of the variable is 3: <em>x³</em>
2. <em>Leading coefficient</em> is the coefficient of the term with the highest exponent: in <em>ax³</em> <em>the leading coefficient is a</em>.
3. General form of a <em>cubic function</em>: ax³ + bx² + cx + d, where a ≠ 0
4. <em>Zeros</em> of a polynomial function are the values of x for which the polynomial values zero: <em>ax³ + bx² + cx + d = 0</em>
<em />
5. When the polinomial is factored you can tell easily which the zeros are.
This is how a factored cubic function looks: a(x - x₁)(x - x₂)(x - x₃), where <em>a is the leading coefficient, and x₁, x₂, and x₃ are the three zeroes of the function</em>.
With that, you can write a cubic function with the restrictions stated:
- l<em>eading coefficien of - 2</em>: a = - 2
- <em>one positive zero</em>: x₁ = 5
- for facility, make the other zeros equal to zero, x₂ = 0, and x₃ = 0
- name the function f(x)
result: f(x) = - 2( x -5)(x - 0)(x -0) = -2(x - 5)(x)(x)
- Expand the expression using distributive property:
- 2x³ + 10x²
In this question , it is given that , the width of a rectangle is 6 2/3 inches.The length of the rectangle is twice its width.
First we need to convert mixed fraction to improper fraction.
And length is twice of width, so length is
The formula of perimeter is two times the sum of length and width.
The answer is 0.00583638102 rad m2
