♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f(x) =  {x}^{2}  + 5

y =  {x}^{2}  + 5

{x}^{2}  + 5 = y

Subtract sides 5

{x}^{2}  + 5 - 5 = y - 5

{x}^{2}  = y - 5

x = ± \sqrt{y - 5}

x≠ - \sqrt{y - 5}

Because x is a positive number but -√y-5 is a negative number thus it's unacceptable.

So ;

x =  \sqrt{y - 5}

_________________________________

{f}^{ - 1}(x)  =  \sqrt{x - 5}

Done...

Angelina wins money in a competition. She is given the choice as to how she is paid.
NISA [10]

Answer:

  • Choice 1
  • 20 days

Step-by-step explanation:

You are being asked to compare the value of a growing infinite geometric series to a fixed constant. Such a series will always eventually have a sum that exceeds any given fixed constant.

__

<h3>a)</h3>

Angelina will get more money from the Choice 1 method of payment. The sequence of payments is a (growing) geometric sequence, so the payments and their sum will eventually exceed the alternative.

__

<h3>c)</h3>

For a first term of 1 and a common ratio of 2, the sum of n terms of the geometric series is given by ...

  Sn = a1×(r^n -1)/(r -1) . . . . . . . . . . series with first term a1, common ratio r

We want to find n such that ...

  Sn ≥ 1,000,000

  1 × (2^n -1)/(2 -1) ≥ 1,000,000

  2^n ≥ 1,000,001 . . . . add 1

  n ≥ log(1,000,001)/log(2) . . . . . take the base-2 logarithm

  n ≥ 19.93

The total Angelina receives from Choice 1 will exceed $1,000,000 after 20 days.
