The tiger population loses 3/5 of its size every 2.94 decades

<h3>Rate of change using differential calculus</h3>

The given equation is:

$N(t)=710(\frac{8}{125} )^t$

Find the derivative of the given function

$\frac{dN}{dt} =710(0.064)^tln(0.064)\\\\\frac{dN}{dt} =-1951.7(0.064)^t$

When the tiger loses 3/5 of its population

dN/dt = 3/5

Solve for t

$\frac{3}{5} =-1951.7(0.064)^t\\\\-0.0003=(0.064)^t$

Take the natural logarithm of both sides

$ln(-0.0003)=t(ln0.064)\\\\-8.087=-2.75t\\\\t=\frac{-8.087}{-2.75} \\\\t=2.94$

The tiger population loses 3/5 of its size every 2.94 decades

line s has a slope of -9/5. line t has a slope of 5/9. are line s and line t parallel or perpendicular

uysha [10]

Answer:

perpendicular

Step-by-step explanation:

If 2 lines are parallel then their slopes are equal

If 2 lines are perpendicular then the product of their slopes = - 1

Here

- $\frac{9}{5}$ × $\frac{5}{9}$ = - 1

Then the 2 lines are perpendicular
