Answer:

C. 3

Step-by-step explanation:

Prime Factorization of 6:  2 × 3

Prime Factorization of 21:  3 × 7

Common Factors of 6 and 21: 3

So the greatest common factor of 6 and 21 is 3, that is, GCF of 6 and 21 is 3.

Question 4 plz show ALL STEPS
scoray [572]

Part (a)

Locate x = -1 on the x axis. Draw a vertical line through this x value until you reach the f(x) curve. Then move horizontally until you reach the y axis. You should arrive at y = 4. Check out the diagram below to see what I mean.

Since f(-1) = 4, this means we can then say

g( f(-1) ) = g( 4 ) = 4

To evaluate g(4), we'll follow the same idea as what we did with f(x). However, we'll start at x = 4 and draw a vertical line until we reach the g(x) curve this time.

<h3>Answer:  4</h3>

==========================================================

Part (b)

We use the same idea as part (a)

f(-2) = 5

g( f(-2) ) = g(5) = 6

<h3>Answer:  6</h3>

==========================================================

Part (c)

Same idea as the last two parts. We start on the inside and work toward the outside. Keep in mind that g(x) is now the inner function for this part and for part (d) as well.

g(1) = -2

f( g(1) ) = f(-2) = 5

<h3>Answer:   5</h3>

==========================================================

Part (d)

Same idea as part (c)

g(2) = 0

f( g(2) ) = f( 0 ) = 3

<h3>Answer:  3</h3>

10 men working for 6 days can complete 5 copies of a book if there are 8 men working to complete 4 copies of the book how many d
Musya8 [376]

Answer:

6 Days

Step-by-step explanation:

Practically:

It takes,

10 Men ( complete ) 5 Copies --> 6 Days

So, 2 Men can complete 1 copy in 6 days.

Question asks us :

8 Men ( complete ) 4 Copies --> X Days

It will take 6 days because the proportion of men to copies is same as the first equation.

Theoretically:

10 Men 5 Copies 6 Days

8 Men   4 Copies  X Days

> 6/X = 8/10 ( If men decrease the number of days increase. So, it is an indirect proportion. ) . 5/4 ( If copies decrease the number of days decrease as well. So, it is a direct proportion. )

> 6/X = 8/10 . 5/4

> 6/X = 40/40

> 6/X = 1

<h2>> X=6</h2><h2></h2><h2><em>I hope it will be understood.</em></h2><h2><em>If I have any inaccuracies please let me know.</em></h2><h2><em>Have a nice day and never stop questioning!</em></h2><h3><em></em></h3>
