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: $c^2 = 9dp$

Which of the following is equivalent to –(–5.25) ? 5 5.25 –5 –5.25<br>please answer fast

Marina86 [1]

Answer:

The equivalent to -(-5.25) = 5.25

Step-by-step explanation:

Given

$-(-5.25)$

We need to determine the equivalent to -(-5.25)

some of the sign rules are:

+(+) = +

−(−) = +

+(−) = -

−(+) = -

Thus,

$-(-5.25)$

Applying the rule: -a(-a) = a

$=5.25$

Therefore, the equivalent to -(-5.25) = 5.25

The University of Central Florida is planning to build a new access ramp for wheelchairs at its education building. The main ent

forsale [732]

Answer:

0.6 feet

Step-by-step explanation:

We solve this question using the Trigonometric function of Tangent.

tan θ = Opposite/Adjacent.

Where:

Opposite = Height /Length of the ramp = ?

Adjacent = Distance from the base of the ramp = 4 feet

θ = 8.1°

Therefore,

tan 8.1° = x/4

Cross Multiply

x = tan 8.1 × 4

x = 0.5692843028 feet

Approximately = 0.6 feet

Length of the ramp = 0.6 feet.

Find the length of the missing side. PLEASE HURRY

Margarita [4]

Answer:

C. 40in

Step-by-step explanation:

$a^{2}+b^{2} =c^{2} \\$

so...

$24^{2} +32^{2} =c^{2}$

$24^{2} = 576\\32^{2} =1024$

576+1024=1600

$\sqrt{1600} = 40$

the missing side = 40in
