How many even k-digit numbers can be constructed out of the digits 3, 4, 5, 6, and 7?

nordsb [41]

Answer:

A. 1562 numbers , B. 130 numbers

Step-by-step explanation:

<u>A)</u> Using same digit again

1 digit nos = 2 ( ie 4 , 6 )

2 digit nos = 5 (ie any no) x 2 ( ie 4 ,6 )

Similarly

3 digit nos = 5 x 5 x 2

4 digit nos = 5 x 5 x 5 x 2

5 digit nos = 5 x 5 x 5 x 5 x 2

Adding all 5 equations

Total = 2 + 10 + 50 + 250 + 1250 = 1562

<u>B)</u> Cant use a digit more than once

1 digit nos = 2 ( ie 4 , 6 )

2 digit nos = 4 ( ie any no other than 4 or 6) x 2 ( ie 4 , 6 )

Similarly

3 digit nos = 4 x 3 x 2

4 digit nos = 4 x 3 x 2 x 2

5 digit nos = 4 x 3 x 2 x 1 x 2

Adding all five equations

Total = 2 + 8 + 24 + 48 + 48 = 130

How to translate f(x)=ln(8-x) into g(x)=lnx

Andreyy89

Step-by-step explanation:

f (x) + n → shifts the function n units upward.

f (x) – n → shifts the function n units downward.

f (x + n) → shifts the function n units to the left.

f (x – n) → shifts the function n units to the right.

–f (x) → reflects the function in the x-axis.

f (–x) → reflects the function in the y-axis.

$f(x)=\ln(8-x)=\ln\bigg(-(x-8)\bigg)\\\\h(x)=f(x+8)=\ln\bigg(-(x-8+8)\bigg)=\ln(-x)\\\\g(x)=h(-x)=\ln\bigg(-(-x)\bigg)=\ln(x)$

STEP 1:

shift the graph 8 units to the left

STEP 2

reflect the graph in the y-axis
