One of the roots of the quadratic equation dx^2+cx+p=0 is twice the other, find the relationship between d, c and p
scZoUnD [109]

Answer:

c^2 = 9dp

Step-by-step explanation:

Given

dx^2 + cx + p = 0

Let the roots be \alpha and \beta

So:

\alpha = 2\beta

Required

Determine the relationship between d, c and p

dx^2 + cx + p = 0

Divide through by d

\frac{dx^2}{d} + \frac{cx}{d} + \frac{p}{d} = 0

x^2 + \frac{c}{d}x + \frac{p}{d} = 0

A quadratic equation has the form:

x^2 - (\alpha + \beta)x + \alpha \beta = 0

So:

x^2 - (2\beta+ \beta)x + \beta*\beta = 0

x^2 - (3\beta)x + \beta^2 = 0

So, we have:

\frac{c}{d} = -3\beta -- (1)

and

\frac{p}{d} = \beta^2 -- (2)

Make \beta the subject in (1)

\frac{c}{d} = -3\beta

\beta = -\frac{c}{3d}

Substitute \beta = -\frac{c}{3d} in (2)

\frac{p}{d} = (-\frac{c}{3d})^2

\frac{p}{d} = \frac{c^2}{9d^2}

Multiply both sides by d

d * \frac{p}{d} = \frac{c^2}{9d^2}*d

p = \frac{c^2}{9d}

Cross Multiply

9dp = c^2

or

c^2 = 9dp

Hence, the relationship between d, c and p is: c^2 = 9dp

Suppose you have a tablet with a capacity of 35 gigabytes. for a plain text​ book, one byte typically corresponds to one charact
steposvetlana [31]
The first thing we must keep in mind is the following unit conversion:
 1 gigabytes = 1 * 10 ^ 9 bytes

 We have then that for 35 gigabytes:
 35 * (1 * 10 ^ 9) = 35 * 10 ^ 9 bytes


 Part A:
 
For this case we make the following rule of three:
 2000 bytes --------------> 1 page
 35*10^9 bytes ----------> x
 From here, we clear x:
 x = (35 * 10 ^ 9) / (2000)

x = 17500000 pages

 Part B:
 
Then, the number of 500-page books is:
 n = (17500000) / (500)

n = 35000
