Answer:
Step-by-step explanation:
The problem presented is one in which the population of the bacteria depreciates by a decay factor r every year.
Since it is a decay problem, we use the model:
Initial Population, P=5000
Decay Rate,r=30%=0.3
t=time interval
Therefore, the equation that represents this situation is:
Answer:
Perimeter: 119.11 units length
Step-by-step explanation:
Assuming that EC is the length of one side of the square and one of the legs (l) of the isosceles right triangle, then the hypotenuse (h) of the right triangle is:
h² = 2*l²
h = √(2*22²)
h = 22√2 units length
The perimeter of the figure is the addition of 3 sides of the square, one leg of the triangle and the hypotenuse of the triangle, that is: 4*22 + 22√2 = 22*(4 + √2) ≈ 119.11 units length
Answer:
5%
Step-by-step explanation:
5×5 =25 and it was for 5 years
1). 6+12k-6k=24k-12
6+6k=24k-12
18=-18k
K= -1
2). 2+12x+6-12x=2x
8=2x
x=4
<h3>2) Rationalize the denominator:</h3>
[ apply radical rule: √a × √b = √ab ]
[multiply the integers] [note: √2 × √2 is 2]
<h3>3) Solve by taking the square root:</h3>
