The fish population of Lake Collins is decreasing at a rate of 5% per year. In 2004 there were about 1,350 fish. Write an expone
ad-work [718]

Answer:

Part 1) The exponential function is equal to y=1,350(0.95)^{x}

Part 2) The population in 2010 was  992\ fish

Step-by-step explanation:

Part 1) Write an exponential decay function that models this situation

we know that

In this problem we have a exponential function of the form

y=a(b)^{x}

where

y ----> the fish population of Lake Collins since 2004

x ----> the time in years

a is the initial value

b is the base

we have

a=1,350\ fish

b=(100\%-5\%)=95\%=0.95

substitute

y=1,350(0.95)^{x} ----> exponential function that represent this scenario

Part 2) Find the population in 2010

we have

y=1,350(0.95)^{x}

so

For x=(2010-2004)=6\ years

substitute

y=1,350(0.95)^{6}=992\ fish

A clothing company plans to shear at least 700 sheep today all novices shear the same number of sheep per day and all experts sh
Llana [10]

Answer:

Each Novis share 7 sheep and each Expert share 12 sheep.

Step-by-step explanation:

Here, N represent the number of novices and E represent the number of experts needed for the company to meet its goal,

∵ All novices share the same number of sheep per day and all experts share the same number of sheep per day.

Let the sheep per day by a Novice = x and sheep per day by an expert = y,

So, the total sheep = xN + yE

According to the question,

Total sheep ≥ 700

⇒ xN + yE  ≥ 700,

By here, we have given the inequality for the given scenario,

7N+12E ≥ 700

By comparing,

x = 7 and y = 12

Hence, Each Novis share 7 sheep and each Expert share 12 sheep.
