Answer:
The minimum cost C(x) = 320 dollars
Step-by-step explanation:
Step(i):-
Given that the function C(x) = 5 x² + 320 ...(i)
Differentiating equation (i) with respective to 'x', we get
C¹(x) = 5 (2x) + 0
C¹(x) = 10 x..(ii)
Equating zero
C¹(x) = 0
⇒ 10 x=0
⇒ x =0
Step(ii):-
Again differentiating equation (ii) with respective to 'x',we get
C¹¹(x) = 10 (1) = 10 > 0
The total cost C(x) is minmimum at x=0
The minimum cost
C(x) = 5 x² + 320
put x= 0
C(x) = 0 + 320
C(x) = 320

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.

Rewrite the following polynomial in standard form.
1-2x- 5x^4 +8x^3
Answer:
-5x^4+8x^3-2x+1
Step-by-step explanation:
The polynomial in standard form is - 5x^4 + 8x^3 -2x + 1.
What is a polynomial?They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.
Example:
x^2 + 3x + 5 is a polynomial.
We need to Rewrite the following polynomial in standard form;
1-2x- 5x^4 + 8x^3
Therefore,
- 5x^4 + 8x^3 -2x + 1
Hence, the polynomial in standard form is - 5x^4 + 8x^3 -2x + 1.

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

State if the three numbers can be the measures of the sides of a triangle. 3, 6, 2 Yes No
Answer:
Step-by-step explanation:
No. 6 is greater than the sum of 3 and 2.
No, These three numbers cannot be the measures of the sides of a triangle.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Three sides of triangle are,
⇒ 3, 6, 2
We know that;
The sum of two sides of a triangle are always greater than the third sides.
Here, Three sides of triangle are,
⇒ 3, 6, 2
So, We get;
⇒ 3 + 2 < 6
Thus, It is not possible to make a triangle.
Therefore, These three numbers cannot be the measures of the sides of a triangle.

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
