Answer: After 30 years there will be 540
Step-by-step explanation:
The function that models the the population growth of the foxes in the wildlife reserve is expressed as
y = 60 times 3^x,
Where
x represents the number of 15-year periods.
The initial number of foxes in the wildlife is 60
Since the population the foxes in the wildlife preserve triples in size every 15 years, in 30 years,
x = 30/15 = 2
Therefore,
y = 60 × 3²
y = 540 foxes
30%=0.3
20%=0.2
10%=0.1
0.3*0.2*0.1=0.006

Step-by-step explanation:
Multiply all values (6.72, 5.78, and 12.7) together, then round to the nearest tenth.
Answer:
9.9
Step-by-step explanation:
-x^2y^2 + x4 + 4y^2 - 4x^2
= x^2(x^2 - y^2) -4(x^2 - y^2)
= (x^2 - y^2) (x^2 - 4)
=(x + y)(x -y)(x + 2)(x - 2)
answer
3.) (x + 2)(x - 2)(x + y)(x - y)
= (y^2 - x^2) (
