x^3 - x^2 + 5x – 5 = 0
Answer:
The final solution is x = i√5, − i√5
Step-by-step explanation:
(x−1)(x2+5)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x−1=0
x^2+5=0
Set the first factor equal to 0 and solve.
x = 1
Set the next factor equal to 0 and solve.
The final solution is all the values that make (x−1)(x2+5)=0 true.
So, final solution is x = i√5, − i√5

The factors of the function, If the zeros of a quadratic function are 3 and 8 will be (x - 3) and (x + 8), i.e. option D.
What is quadratic function?
Quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.
We have,
Zeros of a quadratic function are 3 and 8,
Now,
Let,
[tex]\alpha = 8[/tex] and [tex]\beta=3[/tex]
So,
Now,
Using sum of zeros and product of zeros,
i.e.
[tex]\alpha+\beta=8+3=11[/tex]
And,
[tex]\alpha *\beta =8*3=24[/tex]
So,
The quadratic equation will be in form of ,
[tex]x^2-(\alpha+\beta)x+\alpha\beta=0[/tex]
i.e.
[tex]x^2-(8+3)x+24=0[/tex]
i.e.
[tex]x^2-8x-3x+24=0[/tex]
taking common,
x(x + 8) - 3(x - 8) = 0
(x - 3) (x + 8) = 0
So,
The factor of the quadratic equation are (x - 3) and (x + 8).
Hence, we can say that the factor of the quadratic equation are (x - 3) and (x + 8), i.e. option D.

The slope of the linear model is 1.5. What does this
mean in terms of the maximum noise level and the
number of people?
Answer:
Noise level increase by 1.5 per unit increase in number of persons
Step-by-step explanation:
The slope, m of a linear model is the value which represents the unit change in the dependent variable due to a unit chahe in the independent dependent.
The maximum noise in decibel is the dependent variable while the number of persons is the independent variable. Hence, the Coefficient of the independent vatiabkw is the slope and gives the rate of change in the dependent variable per unit Change in the independent variable.
