1) 7^3 x 7^4 = 7^(3+4) = 7^7
2) (-6)^12 x (-6)^5 x (-6)^2 = (-6)^(12+5+2) = (-6)^19
3) 2^2 x 2^7 x 2^ 0 = 2^(2+7+0) = 2^9
For this case we have a function of the form:
y = A (b) ^ x
Where,
A: initial amount
b: decrease rate
x: time
We have then:
b = 0.15
Therefore the percentage of decrease is:
(1-0.15) * 100 = 75%
Answer:
75%
option 3
Answer:
49
Step-by-step explanation:
