Take half of the coefficient of the bx term and square on both sides:
x^2 - 10x + (-10/2)^2 = 46 + (-10/2)^2
x^2 - 10x + (-5)^2 = 46 + (-5)^2
x^2 - 10x + 25 = 46 + 25
x^2 - 10x + 25 = 71
Now factor x^2 - 10x + 25 which will give us (x - 5)^2
(x - 5)^2 = 71 is the answer.
For this case we have the following expression:
We know that:
Rewriting the expression we have:
For equality to be met we have to:
ANswer:
The value of the variable "y" is -8.
Option A
They are sanjay because three quarts is six pints which means six quarts is 12 pints
<span><u><em>Answer:</em></u>
10 meters
<u><em>Explanation:</em></u>
<u><em>First, we will compute 25% of 8 as follows:</em></u>
25% of 8 = 25% * 8
= 0.25 * 8
= 2
Now, 8 increased by 25% of 8 means that <u>we will add the 25% of the 8 that we computed to the 8</u> we have.
<u><em>Therefore</em></u>:
8 increased by 25% = 8 + 25% of 8
= 8 + 2
= 10 meters
Hope this helps :)</span>
P = -2x^2 + 8x + 2
for maximum P, dP/dx = 0
dP/dx = -4x + 8 = 0
4x = 8
x = 2
The company should produce 2,000 units per week to earn maximum profit.
Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10
Therefore, the maximum weekly profit is $1,000.
