The number of bacteria colonies on a petri dish can be determined by the function below.

A. When the observation began, there were 2 bacteria
colonies,
and the number of bacteria colonies increased by a factor of 3 for every time interval,

(4) = 2(3)
B When the observation began, there were 3 bacteria
colonies,
and the number of bacteria colonies increased by a factor of 2 for every time interval,

Which statement represents the meaning of the aand b values from the function
in terms of the problem situation?

C The final number of bacterial colonies is found by multiplying
the 2 original colonies by 3.

D. After 3 minutes, there are 2 bacteria colonies.

A

Step-by-step explanation:

np have a good night!

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
