Answer:
B. -1
Step-by-step explanation:
x^3-4x^2+2x+10=x^2-5x-3
We know it has 3 roots since it is a 3rd degree polynomial.
Two of the roots are (3+2i) and (3-2i)
Subtract x^2-5x-3 from both sides
x^3-4x^2+2x+10-(x^2-5x-3)=x^2-5x-3 -(x^2-5x-3)
Distribute the minus sign
x^3-4x^2+2x+10-x^2+5x+3=x^2-5x-3 -x^2+5x+3
x^3 -5x^2+7x +13 =0
Graphing this equation , we see that it crosses the x axis at x=-1
That covers the three roots, 1 real and two complex
Answer:
k = 11
Step-by-step explanation:
k/90 - 1/9 = 1/90
k/90 = 1/90 + 1/9
k/90 = 1 + 10/90
k/90 = 11/90
k = 11/90 / 90
k = 11/90 * 90
k = 11
Answer:
20
Step-by-step explanation:
4(2x - 31)=36
4×2x-4×31=36
8x-124=36
8x=36+124
8x=160
x=160/8
x=20
Answer:
<h3>The option b) quadratic function is correct</h3><h3>A nonlinear function with at least one term raised to the power of two is known as a <u>
quadratic function</u></h3>
Step-by-step explanation:
A nonlinear function with at least one term raised to the power of two is known as a <u>quadratic function</u>
FOR :
A non-linear system of equations is a set of equations where one or more terms have a variable of power two or higher .
In Algebra, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Non-linear functions are all other rest functions with exponent atleast 2.
Hence A nonlinear function with at least one term raised to the power of two is known as a <u>quadratic function</u>
<h3>Therefore the option b) quadratic function is correct</h3>
