Exponential decay is the answer
Answer:
2/3
Step-by-step explanation:
First find what fraction of caffeine is hydrogen, 1 - 3/6 - 2/6 - 1/6 = H meaning hydrogen = 0/6 or 0.
Next add O + N + H which is 3/6 + 1/6 + 0/6 which is 2/3.
The other two expressions that have value of 256 is 4⁴ and 16².
Given the exponent expression 2⁸ has a value of 256.
We want to write two other exponential expressions that have value 256.
The given expression is 2⁸=256
The above expression can be written as
2×2×2×2×2×2×2×2=256
By using the Associative property of multiplication, we can write them as
(2×2)×(2×2)×(2×2)×(2×2)=256
4×4×4×4=256
4⁴=256
and it can also be written as by using the associative property of multiplication again and get
(2×2×2×2)×(2×2×2×2)=256
16×16=256
16²=256
Hence, the two other exponential expression of 256 other than 2⁸ is 4⁴ and 16².

Answer:
x = 9
y = 9
Step-by-step explanation:
Given :
Let :
Kenyan French roast coffee = x
Cost per x = $8
Sumatran Coffee = y
Cost per y = $10
x + y = 18 - - - - (1)
8x + 10y = 9 * 18 ;
8x + 10y = 162 - - - - (2)
From (1):
x = 18 - y
Put x = 18 - y in (2)
8(18 - y) + 10y = 162
144 - 8y + 10y = 162
2y = 162 - 144
2y = 18
y = 9
x = 18 - y
x = 18 - 9
x = 9
