Hello,
z=-2x²+15x-3y²+21y-6
=-2(x²-2*15/2*x+(15/2)²) -3(y²-2*7/2y+(7/2)²)-6+2*225/4+3*49/4
=-2(x-15/2)²-3(y-7/2)²+573/4
The max is for x-15/2=0 and y-7/2=0 thus 537/4
Answer:
solution is attached in the picture below
Step-by-step explanation:
We are given with the expression y<span> = b cos t + t2 sin t and is asked to differentiate the function in terms of t. Based in the power law and law of products, we apply these to the given expresssion. the derivative is y' = -b sin t + t^2 * (cos t) + sin t * 2t. This is equal to </span>y' = sin t (-b +2t) + t^2 cos t.
Answer:
Policies to promote competition are high on the political agenda worldwide. But in a constantly changing marketplace, the effects of more intense competition on firm conduct, market structure, and industry performance are often hard to distinguish.
Competition determines market price because the more that toy is in demand (which is the competition among the buyers), the higher price the consumer will pay and the more money a producer stands to make. this good?
