Answers

Answer:

isosceles

Step-by-step explanation:

We first find the |TV| |VS| and |ST| of the triangle using the distant formula,

d =\sqrt{{(x_1 - x)}^(2)+ {(y_1 - y)}^(2) }

|TV|=\sqrt{( {9 - 1)}^(2)+{(2-1)}^(2)}

|TV|=\sqrt{{8}^(2)+{1}^(2) }

|TV|=√(64+1)

|TV|=√(65)units

|VS|=\sqrt{({5- 9)}^(2)+{(8 -2)}^(2)}

|VS|=\sqrt{({ - 4)}^(2)+{6}^(2)}

|VS|=√(16+36)

|VS|=√(52)units

|ST|=\sqrt{({5-1)}^(2)+{(8-1)}^(2)}

|ST|=\sqrt{4^(2)+7^(2)}

|ST|=√(16+49)

|ST|=√(65)units

It can be seen that |ST|=|TV|

This implies that the triangle has its two sides equal.

Therefore the triangle TVS is isosceles.

Note that scalene triangle has three nonequal sides whiles equilateral triangle has three equal sides.

If (3,2) is an ordered pair of the function f(x),which of the following must be an ordered pair of the inverse of f(x)

Answers

Answer:

B. (2,3)

Step-by-step explanation:

If the point (x,y) lies on the graph of an invertible function, then the point, (y,x) must lie on its inverse.

If (3,2) is an ordered pair of f(x), then (2,3) must be an ordered pair of f^(-1)(x)

The correct choice is B.

Answer:

Choice B is correct.

Step-by-step explanation:

We have given the ordered pair of function:

(3,2).

We have to find the ordered pair to inverse of f(x).

If (x,y) is the ordered pair of f(x) then (y,x) is the ordered pair of the inverse of f(x).

The domain of function is the range of its inverse same is the case with the range.

So, the inverse function has (2,3) ordered pair.

Choice B is correct.
