Let be t the tax,
so the <span>tax on the item with a price p is:
t=(12 x p) /100
</span><span>the total price of the item, including tax
let be T=</span>the total price, including tax
so T= t+p, where <span>t=(12 x p) /100
</span>so T = 112p/100
he total price, including tax, of an item that costs 75.
by using T = 112p/10<span>0,
</span>we can get T= 112 x 75 / 100, T=84
the problem is not difficult, so as fo me it is obvious
(a)
If by "age in years" you mean that you only consider whole years, then this is not a one-to-one function, because you will have the same output for 365 inputs:
- If you're 0 to 364 days old, your age in years is 0
- If you're 365 to 729 days old, your age in years is 1
- ....
So, you can see that it is not true that every different input yields a different output.
(b)
This is a one-to-one function: since one mile is 1.609 kilometers, you can convert miles per hour into kilometers per hour by multiplying by 1.609:
x mph = 1.609x km/h
The inverse function would be
x km/h = x/1.609 mph.
Answer:
-4.71239 rad
Step-by-step explanation:
Let "L" represent the population of Linton
and "E" represent the population of Ellmore
12 times E = L
because "Linton is 12 times as great as .. Ellmore"
then E + L = 9646
because "the combined population is 9646"
since L = 12*E
we can plug that into the other equation and get:
E + 12*E = 9646
13*E = 9646 [by adding like terms]
E = 742 [by divided both sides by 13]
so now we have E
we can plug that back into the 1st equation to get L
12*(742) = L
L = 8904
so Population of Linton = 8904
and the Population of Ellmore = 742
