Step-by-step explanation:
Your welcome :)
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.

Shoes and hats are on sale. The expression 1/4(s + 24.80) can be used to determine the discount when you buy shoes with a retail price of s dollars and hats with a total retail price of $24.80. Write another expression that can be used to determine the discount.
Answer:
0.25s + 6.2
Step-by-step explanation:
Discount on sale expression : 1/4(s + 24.80)
Retail price of shoe = s
Retail price of hats = 24.80
From expression, we can conclude that there is a ; 1/4 = 0.25 = (0.25 * 100%) = 25% discount on each item ;
Hence, discount expression could be written as :
0.25s + 0.25(24.80)
0.25s + 6.2

ten times the smallest of three consecutive integers is twenty two more than three times the sum of the integers. find the integers
Answer:
31, 32 and 33
Step-by-step explanation:
Mark these consecutive integers as (n-1), n and (n+1)
(n-1) is the smallest of them
Now write the equation
10 * (n-1) = 3 * (n-1 + n + n+1) + 22
10n - 10 = 3 * (n + n + n) + 22
10n - 10 = 3 * 3n + 22
10n - 10 = 9n + 22
10n - 9n = 22 + 10
n = 32
Now find these three integers
n-1 = 32 - 1 = 31
n = 32
n+1 =32 + 1 =33

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
Mark recorded the temperature each day for a week.
He calculated the mean temperature and found it was 21.6°C
Mark’s thermometer was not working properly. All seven temperatures were 3° too high.
Write down the correct mean temperature.
Step-by-step explanation:
130.2/7= 18.6
Before finding the correct form you need to find their total sum and subtract 21 from it since the number of temperature recordings are 7
