If (he)={(0,1),(2,3),(-4,1)}, find h^-1(x)
ololo11 [35]

The given function is

h(x) = \{ (0,1), (2,3), (-4, 1) \}

The inverse function is

h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}

To get the inverse, we swap each x and y coordinate.

The rule is (x,y) \to (y,x)

So that's why the point (0,1) becomes (1,0) for instance.

Which algebraic properties was applied to the expression a + (b + c) = (a + b) + c?
andrew11 [14]

Answer:

the Associative Property

Step-by-step explanation:

Notice that the ORDER doesn't change -- a, b, c on both sides.  But the GROUPING changes.

Example:

3 + (4 + 5) = (3 + 4) + 5

3 + 9 = 7 + 5

12 = 12

Subtraction does NOT behave this way!

8 - (7 - 1) = 8 - 6 = 2

(8 - 7) - 1 = 1 - 1 = 0

It matters who you associate with!  :-)

Find the length of the third side to the nearest tenth.
Aliun [14]

Answer:

5.3

Step-by-step explanation:

You use the Pythagoras theorem which is a^2+b^2=c^2.

Since you're solving for a side length that's not the hypotenuse you will manipulate the equation to c^2-a^2=b^2. From here you just plug in numbers.

8^2 - 6^2 = b^2

64 - 36 = b^2

b = sqrt(28)

b = 5.2915.... = 5.3
