A scientist is studying a form of bacteria that doubles every hour. if the petri dish starts with 2 grams of bacteria

A - y=2x+2

B - y=2x^2

C - y=2x

D - y=2•2^x

b = 2x²

Step-by-step explanation:

Let the number of bacteria = x

Every hour, the number of bacteria doubles itself, = x * x = x²

But the bacteria started with 2g,

The number of bacteria present is equal to

2 * x² = 2x².

At every hour, the growth of the bacteria is at 2x²

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
