A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft. He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

the answer is d.x= 90°

y= 50°

arc lm= 100°

i got this one chief

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
