Answer:
The correct option is (A).
Step-by-step explanation:
The function representing the growth of number, in billions, of the DNA sequences in a database x years since 2010 is:
The general growth function can be represented as:
Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = growth rate
<em>t</em> = time
Com-paring the two functions we get:
This implies that the annual increase rate in number, in billions, of the DNA sequences is 32%.
Thus, the correct option is (A).
Percent means per one hundred...
p/100=200/740 multiply both sides by 100
p=100*200/740
p=20000/740 %
p=1000/37 %
p≈27.027 %
p≈27% (to nearest whole percent)
Note that
and
.
From the unit circle, we can check that
and
have the same value, but opposite signs, that is:
.
Thus,
.
Note that
is the x-coordinate of the lowest point on the unit circle, that is (0, -1). Thus
Answer: 0
93 is not a prime number. It is not a prime number because it can be divided by 3 to give 31. Prime numbers are numbers that can only be divided by 1 and itself. Hope I helped.
