You subtract 3 cents and add up how many months it is tiil it reaches the same ammout as adding 5 cents and adding up six months every time
Answer:
Domain = R
Range =(0,infinity)
Step-by-step explanation:
Given a function as
y = 4(1/3)^x
The function does not have x or y in the denominator or any square root sign.
Hence we can assign any values to x.
Domain = R = Set of all real numbers = (-infinity, infinity)
Let us consider range.
We find that 4(1/3)^x is a multiple of 4 and powers of 1/3
Since power of 1/3 is always positive, y cannot take any negative value.
When x=0 y =4.
When x tends to -infinity, y tends to 0
So y cannot take the value 0 except at -infinity.
Range =(0,infinity)
Answer:
6 1/6 or 6 2/12
Step-by-step explanation:
2 4/6 + 3 1/2
Get a common denominator
2 4/6 + 3 1/2 * 3/3
2 4/6 + 3 3/6
5 7/6
Rewriting
5 6/6 + 1/6
6 1/6
X=48 degrees
You find the missing degrees in the top triangle. Then you take that degrees and put it in the blank spot right across from the top triangle. To find x you take 180-33=147. The missing degrees was 99 so you take 147-99 and you get 48. You use 180 because that’s the degrees of a whole triangle.
