Let f(x)=x^2+7 and g(x)=x+3/x find (g°)

Step-by-step explanation:

The function f(x) is given to be : f(x) = x² +  7

Also, The function g(x) is given to be :

We need to find : (gof)(-5)

⇒ g(f(-5))

⇒ g((-5)² + 7)

⇒ g(32)

42

step-by-step explanation:

256/6=42

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
