Listen, I'm happy to help you cheat, but couldn't you have just ran this through a calculator? It's not that hard.
Answer:
Number of workers = 20.
Step-by-step explanation:
p = - 4w^2 + 160 w
We need to find the value of w when p is a maximum.
We need to convert the equation to vertex form:
p = -4w^2 + 160w
p = -4(x^2 - 40w)
p = -4 [ (x - 20)^2 - 400]
p = -4(x - 20)^2 + 1600.
So the vertex is at (20 , 1600)
The maximum profit is 1600 and the number of workers = 20.
Hello!
To find the circumference you use the equation
r is the radius
Put this into a calculator and you get the answer of about 351.86
The answer is about 351.86
Hope this helps!
Answer:
1. 6x^2 + 4x - 4y
2. x - 10y.
3. 6x^5
4. 36 a^6 b^8
5. x^2 - 81
6. 9x^2 - 42x + 49
7. 12x^2 +3x - 42
Step-by-step explanation:
1. 3x^2+4x+3x^2-4y
Add the like terms, we get
6x^2 + 4x - 4y
2. (5x-2y)-(4x+8y)
Now distribute the negative sign, we get
5x - 2y -4x -8y
Simplify the like terms, we get
x - 10y.
3. 3x^3(2x)^2
Multiply the numbers and simplify the variables
6x^(3 +2)
6x^5
4. (-6a^3b^4)^2
Now bring the power 2 inside the parenthesis.
-6^2 a^6 b^8
= 36a^6b^8
5. (x+9) (x-9)
x^2 + 9x -9x - 81
x^2 - 81
6. (3x-7)^2
(3x - 7)(3x - 7)
9x^2 - 21x -21x + 49
9x^2 - 42x + 49
7. (3x+6) (4x-7)
12x^2 + 24x -21x - 42
12x^2 +3x - 42
Thank you.
Answer:
