Answer:

D. √2  

Step-by-step explanation:

An <em>irrational number</em> is an irrational number if you cannot express it as the <em>quotient of two integers</em> (except zero as the divisor).

A.         ⁷⁴/₉₉ = quotient of two integers

<em>Rational </em>

B.   √4 = 2

     √4 =  ²/₁ = quotient of two integers

<em>Rational </em>

<em> C.</em>            ¾ = quotient of two integers

<em>Rational </em>

<em> D.</em>          √2 = 1.414 213 562 …

             √2 = <em>not</em> quotient of two integers

Irrational

A retailer who sells backpacks estimates that by selling them for x dollars each, she will be able to sell 100−x backpacks each
zvonat [6]

Answer:

x = 50

R = $2500

Step-by-step explanation:

Given in the question a quadratic equation,

−x² + 100x

To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x

The value of -b/2a tells you the value x of the vertex of the function

−x² + 100x

here a = -1

        b = 100

Selling price = -(100)/2(-1)

                    =   50

 

R = −(50)² + 100(50)

  = 2500

The initial population of a town in the year 2010 was 20 000. By 2014, the population had grown exponentially to 32 500 people.
stiv31 [10]

Answer:

  P = 20000×1.625^(n/4)

Step-by-step explanation:

An exponential equation can be written using the given data:

  value = (initial value)×(growth factor in period)^(n/(period))

Here, the growth is by a factor of 32500/20000 = 1.625, and the period is 4 years. Then your exponential equation is ...

  P = 20000×1.625^(n/4)
