<u>Options</u>

(A)\left(-\infty , \dfrac23\right]\\\\(B)\left(-\infty , \dfrac23\right) \\\\(C)(\frac23\right, \infty ) \\\\(D) [\frac23\right, \infty )

Answer:

(C)(\frac23\right, \infty )

Step-by-step explanation:

Given the solution to an inequality

{x|x>2/3}

The solution set does not include \dfrac23 , therefore, it must be open at the left. Recall that we use a curvy bracket ( to denote openness at the left.

Since x is greater than  \dfrac23 , the solution set contains all values of larger than  \dfrac23 up till infinity. Since infinity is an arbitrarily large value, we also use an open bracket at the right.

Therefore, another way to represent the solution {x|x>2/3} is:

(\frac23\right, \infty )

The correct option is C.

1/3x=5/12 show your work
insens350 [35]

Answer:

4/5 or 0.8

Step-by-step explanation:

1/3x = 5/12

<em>cross</em><em> </em><em>multiply</em>

(12×1) = (5×3x)

<em>divide</em><em> </em><em>through</em> <em>by</em> <em>1</em><em>5</em>

x = 12/15

x = 4/5 <em>o</em><em>r</em><em> </em>0.8

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
