The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?
Answers
Answer:
625
Step-by-step explanation:
Let two number be x and (50-x).
The product of numbers be x(50-x).
P = 50x-x²
For maximizing the product,
[tex]\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25[/tex]
So, the maximum product, P = 50(25)-(25)²
P = 625
Hence, the maximum value of the product of these two numbers is 625.

5x + 5x = 10x
Combine like terms: 5x + 5x = 10x
10x = 10x
Add '-10x' to each side of the equation.
10x + -10x = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 0
Step-by-step explanation:
Answer: 5x+5x=10x²
10x=10x²
10x²+ -10x²=0
10x+-10x²=0
10x(1+ -1x)=0
ignore the factor 10

Lead-the-market pay strategies. An employer may choose to establish an internal compensation strategy that is in excess of the pay rates in the prevailing marketplace. This compensation strategy may increase the supply of candidates, increase selection rates of qualified acpplicants, decrease employee turnover, increase morale and productivity, or prevent unionization efforts. However, prior to implementing a lead compensation strategy, an organization should carefully consider what benefits it expects to realize from such a strategy, keeping in mind that this type of structure has the greatest propensity of increasing overall labor costs.

y = 25x + 128.8
Step-by-step explanation:
y = total cost
x = amount of days the car was rented
25 represents the daily charge for the fee and the insurance (15+10=25)
128.8 represent the cost for miles driven by Jerry
This was calculated by multiplying the amount of miles he drove (644) by the cost of each mile (.20)
644x.20=128.8 so the cost for miles driven is $128.8 which is why it was added to the equation
