Answer:

10.30

Step-by-step explanation:

Pythagorean Theorem is a^{2} + b^{2} = c^{2}.  The short leg(a) is 5 units long and the long leg(b) is 9 units long.  CD is the hypotenuse, the longest side (c).

5^{2} +9^{2} =c^{2}

25+81=c^{2}

106=c^{2}

\sqrt{106} = \sqrt{c^{2} }

10.29563014 = c

Rounded to the nearest hundredth, 10.30

To check this is correct, the hypotenuse is the longest side, and 10.30 is longer than 5 and 9.

Use the rule to write the first five terms of the pattern.
AlekseyPX

Answer:

A =First term of the pattern = 11

To find the first five terms we have to use the rule which is

Add 10 to first term and then subtract 5 from it.Which is equivalent to

= A +10 -5

1. Second Term = 11 + 10 -5

  = 21 - 5

   =16

→Third term = 16 +10-5

        = 26 - 5

       = 21

→Fourth term : 21 + 10 - 5

     = 31 -5

      = 26

→Fifth term : 26 +10 -5

                = 36- 5

                = 31

→Sixth term:

=31 + 10- 5

= 41 -5

 = 36

So, the first five term apart from 11 is 16, 21,26,31,36 which is an Airthmetic progression.

If ƒ(x) = 2x, then ƒ -1(x) =<br><br> -2x<br> ½x<br> x - 2
kap26 [50]

Answer: second option

Step-by-step explanation:

To find the inverse function of the given function f(x):

f(x)=2x

You need to:

Substitute f(x)=y into the function:

 y=2x

Now, you need  to solve for "x", to do this, you must divide both sides of the function by 2:

\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x

Now, replace "x" with "y" and replace "y" with "x":

\frac{x}{2}=y

Therefore, substituting y=f^{-1}(x) you get:

f^{-1}(x)=\frac{x}{2} or  f^{-1}(x)=\frac{1}{2}x
