The equation of line is y = x. the midpoint of bc is (a + c, b). does the midpoint of bc lie on ? why or why not? no, because b does not equal a + c no, because (a + c) does not equal b yes, because b = a + c yes, because (a + c) = b

yes, because (a+c) =b

Step-by-step explanation:

Given that equation of the line is y=x.

B and C are two points lying on this line.

Midpoint of B and C are given as (a+c, b)

From this we see that using midpoint formula

Since both points lie on y=x, we get

x1=y1 and x2=y2

So x1 = a+c and 2y1 = 2b or y1 =b

Since x1=y1, we have a+c =b

i.e. the coordinates of mid point satisfy the equation y=x

Hence answer is

yes, because (a+c) =b

yes because (a + c) = b

Step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
