Luke goes to the fair with $50. Each ride costs $2. If an equation is written to show how much money Luke has at the end of the day, what is the slope and y-intercept? A. slope = 50; y-intercept = 2
B. slope = 25; y-intercept = 50
C. slope = 25; y-intercept = 2
D. slope = -2; y-intercept = 50

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.
