A bacteria culture has 2,000 bacteria. The number of bacteria increases by 5% each hour. How many bacteria are there after 12 ho
ivann1987 [24]
Suppose the number of bacteria are increasing exponentially, We can model the number of bacteria at a given time t, using the formula:
f(t)=ae(tk)
where, k=constant of proportionally and a=initial number;
thus;
f(t)=2000e(0.005t)
Therefore the population after 12 hours will be:
f(12)=2000e^(0.005*12)
f(12)=2,123.67=2,123 bacteria

Answer:

8

Step-by-step explanation:

use trig functions

2 sides and 1 angle given

Sides given

  • hypotenuse -> x
  • opposite side to 30˚ -> 4

Angle

  • 30˚

trig function associated with hyp and opp is sin

sin(x) = opp/hyp

substitute

sin 30˚ = 4/x

solve for x

0.5 = 4/x

0.5x = 4

x = 8

A polynomial which has only one term is called monomial

The degree of a monomial is defined as the sum of all the exponents of the variables

<em>Examples</em>

If the monomial has only one variable

3x² -----> is a monomial of the 2 degree with a leading coefficient of 3

If the monomial has more than one variable

3xy ----> is a monomial of the 2 degree with a leading coefficient of 3
