The area is be at least (because the bear could continue walking while the people start looking) 8 square miles, because 2 miles per hour, times, 4 hours of walking this fast is 8 miles. But because it is any direction it has to be squared (because you are finding area). -8 miles^2
Answer:
f ( x ) = -3x + 1
to find it's inverse let f(x)= y
y= -3x + 1
x = - 3y + 1
-3y = x -1
y = -(x -1)/3
Hope this helps.
Answer:
(3 x X) + 2
Can be a possible way if you factor it out I think.
Answer:
The age of the spear head is of 1938 yers.
Step-by-step explanation:
The amount of carbon 14 after years is given by the following equation:

In which Q(0) is the initial amount and r is the decay rate.
The half life of carbon 14 is 5700 years.
This means that 
So








So

We have to find:
t for which Q(t) = 0.79Q(0). So








Rounding to the nearest year.
The age of the spear head is of 1938 yers.
