Answer:
a^2 +b^2=c^2
Given vertices of the triangle are A(4,4),B(3,5) and C(−1,−1) 
We know that slope of line passing through the points (x 1,y 1) and (x 2,y 2
) is given by m= x 2−x 1

⇒ line segments AB and CA are perpendicular to each other i.e; the given triangle is right angled at A(4,4).
Thus the points (4,4),(3,5) and (1,1) are the vertices of a right angled triangle.

You will first find the unit rate which is single in four hours so then multiply by triple which is 3 and then you get triple will be in 12 hours

Answer:

Step-by-step explanation:
We want to find the inverse of the function: 

To find the inverse of a function, we will flip the variables and solve for <em>y</em>. So: 

Solve for <em>y</em>. Subtract two from both sides: 

Divide both sides by two: 

And take the principal square root of both sides. Therefore:
