The population of Bengal tigers in a region of India can be modeled by the function P = 450(0.85), where P is the population and I is the number of years since 2000.
What is the Bengal tiger population in 2000?
and by what percent does the tiger population decrease each year?

(a) The population in 2000 is 450

(b) 15% decreases each year

Step-by-step explanation:

Given

--- since 2000

Solving (a): The population in 2000

First calculate t

--- years since 200

So, we have:

Solving (b): Rate of population decrease

A function that decreases is represented as:

Where

answer: what equations are there

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
