Maximum value of log5 3x+4y if x2+y2 25 is
Web3. Find the absolute minimum and absolute maximum value of the function f(x;y) = 2x3 + y4 on the regionD= (x;y) : x2 +y2 1. Solution. In order to find the absolute maximum and absolute minimum values of a function on a bounded domain D, we not only have to find and consider all critical points, but we have to check alongtheboundariesoftheregion. WebBefore we can say these are global max or mins, we need to look for critical points in the interior of the circle x2+y2 ≤ 4. Set fx = 0 ⇒ 2x = 0 and f y = 0 ⇒ 4y = 0 The only critical points is (0, 0), and this is in the interior of the circle. The value of f(0,0) = 0. Combining the results on the boundary with the only critical point we see:

Web4xy= 48 - x2 or We wish to MAXIMIZE the total VOLUME of the box V= (length) (width) (height) = (x) (x) (y) = x2y. However, before we differentiate the right-hand side, we will write it as a function of xonly. V= x2y = 12x- (1/4)x3. Now differentiate this equation, getting V' = 12 - (1/4)3x2 = 12 - (3/4)x2 = (3/4)(16 - x2) Webx2+2xy-35y2 Final result : (x + 7y) • (x - 5y) Step by step solution : Step 1 :Equation at the end of step 1 : ( (x2) + 2xy) - (5•7y2) Step 2 :Trying to factor a multi variable polynomial : …
Webx+y will have maximum value when a line is farthest from the origin but in hold of the circle so that x²+y²=4 is not violated i.e. line is tangential to the circle. At point of tangent, x = y Therefore, x + y = 2√2 3 Quora User Worked at ITC Limited (1979–2002) Author has 2.9K answers and 1.1M answer views 2 y As x^2+y^2=4, x<=2 and y<=2.

WebSo, log 5[Max(3x+4y)]=log 525=2 Or Let f(x,y)=3x+4y be a function. So we have to find maxima of f(x,y) if x 2+y 2=25. f=3x+4 25−x 2 For maxima f(x) must be 0. ⇒3− 25−x 24x … Webmaths If x2+y2=25, then log5 [Max(3x+4y)]is A 2 B 3 C 4 D 5 Video Explanation Answer Correct option is A 2 Lets take x=5cosθ,y=5sinθ then Max(3x+4y)=Max[5(3cosθ+4sinθ)] …
Webmaximum and minimum values of f(x) was you asked yourself Suppose that the largest (or smallest) value of f(x) is f(a). What does that tell us about a? After a little thought you answered If the largest (or smallest) value off(x) is f(a) andf is differentiable ata, then f′(a) = 0. Let’s recall what that’s true.
