Answer:

see explanation

Step-by-step explanation:

To solve the given quadratic equations, equate to zero, factorise and solve

given

x² - 19x + 48 = 0

Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 19)

The required factors are - 3 and - 16, hence

(x - 3)(x - 16) = 0

equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 16 = 0 ⇒ x = 16

----------------------------------------------------------------

given

x² + 21x - 100 = 0

Consider the factors of the constant term (- 100) which sum to give the coefficient of the x- term (+ 21)

The required factors are + 25 and - 4, hence

(x + 25)(x - 4) = 0

x + 25 = 0 ⇒ x = - 25

x - 4 = 0 ⇒ x = 4

A sphere has a diameter of 24 units. What is its volume in cubic units?

DiKsa [7]

Hello!

The equation to find the volume of a sphere you use the equation

$\frac{4}{3} \pi r^{3}$

r is radius which is half the diameter

put in 3.14 for pi and 12 for r

$\frac{4}{3} *3.14* 11^{3}$

This gives us the answer of 7234.56 cubic units

Hope this helps!
