The area of a circle is 201 cm². What is the diameter

natima [27]

Answer:

The diameter would be 16

Step-by-step explanation:

The area of a circle is a= $r^{2}$ ×π. Now just plug in the values you have which is you area. 201= $r^{2}$ ×π now divide by pi on both sides you that you get about 64= $r^{2}$ . Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16

If you were solving a system of equations and you came to a statement like 1 = 3, what do you know about the solution to the sys

noname [10]

<h2>Key Ideas</h2>

Systems of equations

<h2>Solving the Question</h2>

When both sides of the equal sign are equal, there are infinite solutions.

When you are able to isolate the variable, there is only one solution.

When the equation states an untrue expression, there is no solution.

1=3 is an untrue fact. Therefore, there would be no solutions to the system.

<h2>Answer</h2>

There is no solution

Answer:

A = {put, the, cake, in, basket}

B = {is, the, cake, in, basket}

C = {no, the, cake, in, basket}

D = { }

Step-by-step explanation:

A = (A -B) ∪ (A∩B) ∪ (A∩C}

A = {put} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}

A = {put, the, cake, in, basket}

B = (B -A) ∪ (B -C) ∪ (B∩A) ∪ (B∩C)

B = {is} ∪ {is} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}

B = {is, the, cake, in, basket}

C = (C -B) ∪ (C∩A) ∪ (C∩B)

C = {no} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}

C = {no, the, cake, in, basket}

D = { } . . . . not defined anywhere

F(x)=9(x-8) find f^-1(x)

mina [271]

Answer:

$f^{-1}$ (x) = $\frac{1}{9}$ x + 8

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 9(x - 8) ← divide both sides by 9

$\frac{y}{9}$ = x - 8 ( add 8 to both sides )

$\frac{y}{9}$ + 8 = x

Change y back into terms of x with x = $f^{-1}$ (x) , thus

$f^{-1}$ (x) = $\frac{1}{9}$ x + 8
