Replace every x in the function with a -2. 3(-2)^2 - 2(-2) + 7. Simplifying gives you 3(4) + 4 + 7. Do the math now. 12 + 4 + 7 = 23
Answer:
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. ... Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation.

Answer:
The function that represents the mass of the sample after t days is
.
The percentage rate of change per hour is of -2.46%.
Step-by-step explanation:
Exponential amount of decay:
The exponential amount of decay for an amount of a substance after t days is given by:

In which A(0) is the initial amount, and r is the decay rate, as a decimal.
Element X is a radioactive isotope such that its mass decreases by 59% every day. The experiments starts out with 390 grams of Element X.
This means, respectively, that 
So



The function that represents the mass of the sample after t days is
.
Hourly rate of change:
Decreases by 59% every day, which means that for 24 hours, the rate of change is of -59%. So
-59%/24 = -2.46%
The percentage rate of change per hour is of -2.46%.
200 is the answer so it would equal to 2 hundreds
