Let A = (−3, 2), B = (1, 0), and C = (4, 6). Prove that △ABC is a right-angled triangle. Let u = AB, v = BC, and w = AC. We must show that u · v, u · w, or v · w is zero in order to show that one of these pairs is orthogonal. u · v =
u · w =
v · w =
Since , △ABC is a right-angled triangle.
A. AB ⊥ BC
B. BC ⊥ AC
C. AB ⊥ AC

72 is the answer to this problem

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
