For a, we have 42in/9ft. Since 12 inches are in 1 foot, we can multiply it by that to get (42in/9ft)*(1ft/12inches) = 42/108. We put the foot on the top of 1ft/12in to cancel them out. Since 2 goes into both 42 and 108, we divide it by 2/2 to get 26/54. Repeating the process again, we get 13/27
If we were to say that there are 12 inches in a foot and therefore divide 42 by 12 (to get 42 inches in feet), we'd get the same answer due to that 1 foot is equal to 12 inches and if you were to divide it by 1 foot/12 inches, since they are the same thing, you get the same answer
For c, since it may be hard to get (42/12)/9, it could just be easier to have 42/(9*12)=42/108
Answer:
With the rule: d(n) = d(n-1) x (-5), we have:
d(1) = 8
d(2) = d(1)x(-5) = 8x(-5) =-40
d(3) =d(2)x(-5) = -40x-5 =200
Other way:
d(n) = d(n-1) x (-5) => d(n) = d(1)x(-5)^(n-1)
d(3) = d(1)x5^(3-1) =8x5^2=8x25 =200
we know that
domain is all possible values of x for which any function is defined
so, here domain will be all possible values of x fro which y is defined
so, we will find minimum and maximum value of x
we can see that
x starts from 0
so, minimum value is x=0
and it goes to right upto infinity
so, domain will be
