The tables show functions representing the growth of two types of bacteria on certain days within an experiment that lasted a to
tal of 10 days. How do the functions in the table compare? A. Since x-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start. B. Since y-intercepts indicate the amount of each bacteria at the start of the experiment, there was more of bacteria B than bacteria A at the start. C. Since the maximum value in the table for bacteria A is greater than the maximum value in the table for bacteria B, bacteria A has a faster growth rate than bacteria B. D. Since the minimum value in the table for bacteria A is less than the minimum value in the table for bacteria B, bacteria A has a slower growth rate than bacteria B.

Answer:
The value of is 16.
Step-by-step explanation:
The given expression is .
Put x = 2 in the above expression as follows :
Hence, the final answer is 16.
Step-by-step explanation:
OPQ originally forms a sector, the formula for sector is
where x is the degrees of rotation between the two radii.
We know three sides length and is trying to find an angle between the radii so we can use law of cosines which states that
This isn't the standard formula, it's for this problem
So we found our angle of rotation, which is 106.26
Now, we do the sector formula.
is the area of sector.
Now let find the area of triangle, we can use Heron formula,
The area of a triangle is
where s is the semi-perimeter.
To find s, add all the side lengths up, 10,10,16 and divide it by 2.
Which is
So our area of the triangle is 48. Now, to find the shaded area subtract the main area,( the sector of the circle) by the area of the triangle so we get
Which is an approximate or
