Identify the parent function that can be used to graph the function f(x) = - 3x +2

Nat2105 [25]

Answer:

$f(x)=x$

Step-by-step explanation:

We are given with the function f(x) = -3x+2

we have been asked to find the parent function?

As we can see there are two kinds of Tranformation applied here

$f(x)+b$ and $f(-ax)$

So Here the parent function is $f(x)=x$

Using the above two mentioned transformations the parent $f(x)=x$ has been converted to $f(x) = -3x+2$

Hence the parent Function is $f(x)=x$

Answer:

<h2>13 years</h2>

Step-by-step explanation:

Given, 

No. of children = 5

Ages of the children = 12, 18, 13, 16 and 6 years

Therefore, 

Average age of the children

$= \frac{sum \: of \: the \: ages \: of \: children}{no. \: of \: children}$

$= \frac{12 + 18 + 13 + 16 + 6}{5}$

$= \frac{65}{5}$

A boat cost $16,500 and decreases in value by 13% per year how much will the boat be worth after eight years?

sergeinik [125]

Answer:

$5,415.49

Step-by-step explanation:

Cost of the boat = $16,500

Decrease in value per year = 13%

Worth of the boat in 8 years = ?

Remaining value = 100% - 13%

= 87%

Worth of the boat in 8 years = cost of the boat × remaining value^8

= $16,500 × 87%^8

= $16,500 × 87/100^8

= $16,500 × 0.87^8

= $16,500 × 0.3282116715437121

= $5,415.49

The worth of the boat after 8 years = $5,415.49

Answer:

The value of k is 1.

Step-by-step explanation:

You have to apply Indices Law :

${a}^{m} \times {a}^{n} = {a}^{m + n}$

For this question :

${( \frac{4}{5} )}^{2} \times {( \frac{4}{5} )}^{5} = {( \frac{4}{5} )}^{6k + 1}$

${( \frac{4}{5}) }^{2 + 5} = {( \frac{4}{5}) }^{6k + 1}$

$by \: comparison$

$2 + 5 = 6k + 1$

$7 = 6k + 1$

$7 - 1 = 6k$

$6k = 6$

$k = 6 \div 6$

$k = 1$
