how do I find a whole number x so that the ratio x:113 is a better estimate for pi than 22/7 and 3.14

1 answer:

7 0

22/7 = 3.142857...

Let's see if we can beat this using a fraction with 113 as its denominator.

-------

3 x 120 = 360

-------

So, let's try out x = 360:

360/113 = 3.185.... (Too high)

How about x=350:

350/113 = 3.097... (Too low)

Let's try out x = 355:

355/113 = 3.14159292 (Calculator value)

--------

Let's now compare 22/7 and 355/113 to pi:

22/7 = 3.142857...

355/113 = 3.14159292 (Calculator value)

π = 3.141592654

-------

As we can see, 355/113 provides us with a better approximation of π. This means that x=355.

Answer:

33, 57

(not 100% sure this is correct)

Step-by-step explanation:

90= x +(24 +x)

90 = 2x + 24

<em>(Subtract 24 from 24 and 90 from 24)</em>

66 = 2x

<em>(Divide both by two)</em>

33 = x

24 + x = 57

Rainbow [258]

Answer:

12%

Step-by-step explanation:

So 5.5 to 5.62 is .12

Then calculate the difference of 5.5 *.12=0.66

Then do “0.66 is what percent of 5.5?”

The answer is 12%

2. Graph the inverse of the function, then determine if the inverse is a function.

charle [14.2K]

The inverse of the function f(x)= x^2 is a function.

<h3>The graph of the inverse</h3>

The equation of the function is

f(x)= x^2

Rewrite as:

y = x^2

Swap x and y

x = y^2

Make y the subject

$y = \sqrt x$

Rewrite as:

$f^{-1}(x) = \sqrt x$

So, the inverse of f(x)= x^2 is $f^{-1}(x) = \sqrt x$

See attachment for the graph

<h3>Is the inverse a function?</h3>

The inverse is a function.

This is so because it passes the vertical line test
