The volume of a sphere can be determined by the formula V = 4/3 πr^3, where r is the radius. What is the volume of a sphere with
allochka39001 [22]

Answer:

V = \frac{99}{7} x^{9}y^{-6}

Step-by-step explanation:

Given

V = \frac{4}{3}\pi r^3

Required

Find V when

r = \frac{3}{2}x^3y^{-2

Substitute \frac{3}{2}x^3y^{-2 for r in V = \frac{4}{3}\pi r^3

V = \frac{4}{3}\pi * (\frac{3}{2}x^3y^{-2})^3

Open bracket

V = \frac{4}{3}\pi * \frac{3}{2}^3 * x^{3*3}y^{-2*3}

V = \frac{4}{3}\pi * \frac{27}{8} * x^{9}y^{-6}

Simplify the fractions

V = \pi * \frac{9}{2} * x^{9}y^{-6}

Let

\pi = \frac{22}{7}

So:

V = \frac{22}{7}  * \frac{9}{2} * x^{9}y^{-6}

V = \frac{11}{7} * \frac{9}{1} * x^{9}y^{-6}

V = \frac{99}{7}   * x^{9}y^{-6}

V = \frac{99}{7} x^{9}y^{-6}

55. (a) If alpha and beta are the roots of the equation xsquare+ px+q=0 and beta>alpha find the square of the
densk [106]

Answer:

√(p²-4q)

Step-by-step explanation:

Using the Quadratic Formula, we can say that

x = ( -p ± √(p²-4(1)(q))) / 2(1)  with the 1 representing the coefficient of x². Simplifying, we get

x = ( -p ± √(p²-4q)) / 2

The roots of the function are therefore at

x = ( -p + √(p²-4q)) / 2 and x = ( -p - √(p²-4q)) / 2. The difference of the roots is thus

( -p + √(p²-4q)) / 2 - ( ( -p - √(p²-4q)) / 2)

= 0 + 2 √(p²-4q)/2

= √(p²-4q)
