Best ResponseYou've already chosen the best response.0okay this is the instructions...Use implicit differentiation to find the value of dy/dx at the indicated point. e^y+2y=3x5 ; at the point (2,0)

Best ResponseYou've already chosen the best response.0(dy/dx)e^y + 2dy/dx = 3 dy/dx(e^y + 2) = 3 (dy/dx)= 3/(e^y + 2) plug in the value of x an y in the equation but there isn't a y varible ( dy/dx)= 3/(e^0 + 2) ( dy/dx)= 3/3 = 1

Best ResponseYou've already chosen the best response.0remember dy/dx e^(f(x)) = f'(x)e^(f(x))

Best ResponseYou've already chosen the best response.0implicate differentiate is all about in term of a variable and the variable in this problem is x. So differentiate the polynomials and if DOESNT have x in the polynomial then add dy/dx to the polynomial

Best ResponseYou've already chosen the best response.0xy2x=y ^{2}  4 ; at the point (5,3) xdy/dx + y  2 = 2ydy/dx /// remember the multiplication rule dy/dx(2y  x)= y2 dy/dx= (y2)/((2y  x)) plug in values (31)/(65)= 2

Best ResponseYou've already chosen the best response.0a women standing on a cliff is watching a motorboat through a telescope as the boat travels away from the base of the cliff. The telescope is 250 feet above the water level and the boat is traveling at a speed of 20 feet per second. How fast is the distance between the woman and the boat increasing at the moment when the boat is 600 feet from away?

Best ResponseYou've already chosen the best response.0here is what i did x^2 + 250^2 = z^2 2x + 0 = 2z 2x dx/dt = 2z dx/dt 600dx/dt=650(+20) dx/dt = 21.7 ft/s

Best ResponseYou've already chosen the best response.0The boat and the women are in a triangle formation. So \[x^2 +y^2 = z^2\] implicit differentiate in terms of time. so \[(x) dx/dt + (y) dy/dt = (z) dz/dt\] where x= the distance the boat is and dx/dt the rate of the boat moving away. because the women is sationary the women's dy/dt is 0.

anonymous

Best ResponseYou've already chosen the best response.0So (x)dx/dt=(z)dz/dt 600* 20 = z dz/dt we are trying to find dz/dt but we don't have z x^2+y^2=z^2 600^2 + 250^2 = z^2 z=650

Best ResponseYou've already chosen the best response.0number 17: 2x^3+ 3x^2 = 2 = f(x) 12x^2 + 6x = f'(x) = 0 at x =1/2 and x= 0 24x+ 6 = f''(x) = 0 at 1/4

Best ResponseYou've already chosen the best response.0increasing [∞. 1/2][0, ∞] decreasing [1/4,1/2] local/absolute maximum when f'(x) = 0 and f''(x) < 0 at x=1/2 local/absolute minimum when f'(x) = 0 and f''(x) > 0 at x=0

Best ResponseYou've already chosen the best response.0find the intervals of decreasing and increasing take the derivative and set it to zero. the number plug it in the ORIGINAL f(x) and if the number is negative the between the local max or min it is decreasing and whent he number is positive between the local max or min it is increasing

anonymous

Best ResponseYou've already chosen the best response.0to find the local max and min.... find f''(x) and plug in the f'(x) number and if it is negative (positive) it is a local maximum(minimum). of the local max and min plug them in the original f(x) AND which ever the local max or min is the most positive or negative is the absolute max or min respectively.
