Answer:
B. There were 60 nano-related patents granted in 1991
Step-by-step explanation:
In the expression:
60⋅1.2^t
t is years after 1991, that is, in the year 1993, t = 2
60 is the value of the expression at t = 0, then it represents the amount of nano-related patents granted in 1991
81 is 45% of 180, all you do is divide 81 by .45 and boom there you go
If $36 is 3/4 of the total cost, then you can divide 36 by 3 to get the answer for what 1/4 of the cost is. 36 divided by 3 is 12. 12 times 4 is 48. the cost is $48.
(4x+2)²-3
16x²+4-3
16x²+1
Hope this helps :)
The correct answer is 0.775255128608411.
