At 10:05 a.m., there are 2 microscopic bacteria cells in the bottle. At 10:15 a.m., there are 8 cells in the bottle.

zloy xaker [14]

Answer: At 10:20 a.m., there will be 16 cells in the bottle.

At 10:30 a.m. there will be 64 cells in the bottle .

Step-by-step explanation:

Since we have given that

At 10:05 a.m. number of microscopic bacteria cells in the bottle = 2

At 10:15 a.m. number of microscopic bacteria cells in the bottle = 8

It means in every 5 times the number of microscopic bacteria cells in the bacteria gets twice itself.

So, by following the same pattern we can get that,

At 10:20 a.m. number of microscopic bacteria cells in the bottle is given by

$8\times 2=16$

Hence, At 10:20 a.m., there will be 16 cells in the bottle.

Similarly,

At 10:25 a.m. number of microscopic bacteria cells in the bottle is given by

$16\times 2=32$

At 10:30 a.m. number of microscopic bacteria cells in the bottle will be

$32\times 2=64$

Hence, At 10:30 a.m. there will be 64 cells in the bottle .

The discriminant of equation ax^2+bx+c = 0 is b^2-4ac.

Here b = 12, a = -4, c = -9 so discriminatn is

b^2-4ac = 12^2-4(-4)(-9) = 144 - 144 = 0.

The discrimant is 0. This tells us that there is only 1 x-intercept for this quadratic
