Mr. Martinez is comparing the price of oranges from several different markets. Determine whether each market uses proportional or nonproportional pricing. Place a checkmark in the column for the correct type of relationship. Show your work. a: 5/3.50; 10/6.50; 15/9.00; 20/10.25

b: 5/3.25; 10/6.60; 15/9.75; 20/13.00

c: 5/3.75; 10/7.50; 15/11.25; 20/15.00

d: 5/65; 10/ 7.30; 15/ 20.80; 20/14.30

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

Find the value of x. round the length to the nearest tenth

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
