Given

The equation in the form

x^{4}+95x^{2}-500 =0

Find the factor of the above equation

To proof

factoring the above equation

we get

x^{4}+100x^{2}-5x^{2}-500 =0\\\\x^{2}(x^{2}+100)-5(x^{2}+100)=0\\\\(x^{2}-5)(x^{2}+100)=0

now sloving the equation we get the value

x² = 5

x² = -100

x =\pm \sqrt{5}\\\\ x=\sqrt{-100}

The factor of the equation is

x=\pm \sqrt{5}\\\\ x= \pm 10i

Hence proved

The number of acres in a region cleared for farming follows the formula a = f (t) = 2t2 where t is the number of months since th
Anit [1.1K]

we are given

a=f(t)=2t^2

we can use average rate of change formula from t=a to t=b

A=\frac{f(b)-f(a)}{b-a}

Here, we are given from t=1 to t=4

so, we will get formula as

A=\frac{f(4)-f(1)}{4-1}

now, we can plug values

A=\frac{2(4)^2-2(1)^2}{4-1}

now, we can simplify it

A=10

the average rate of change in the number of acres cleared for farming between t = 1 and t = 4  is 10 acres/ month.............Answer

It will take 12 weeks to pay for the DVD players.

Step-by-step explanation:

Given in the question that,

total cost of DVD bought by Adela = $210

Step 1

Adela makes a down payment of $30

$210 - $30 = $180

Remaining cost = $180

Step 2

Adela pays $15 each week

$15 = 1 week

$180 = ?

$1 = 1 week/15

$180 = 180/15 week
