Richard planted some grass on a rectangular plot of land which measures 12 meters by 8 meters. he left a margin of 0.5 meters around the grass , as shown in the figure below. find the area of land covered by grass.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

the correct answers are 1, 2, 4, and 5! i just got it right!

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !

triangle eg 7.5 × cos "a" or 7.5 × sin "b" or 6 tan"a"
