Factorize

(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0

Solve both for n

3n + 8 = 0
3n = -8
n = -8/3


3n - 8 = 0
3n = 8
n = 8/3

Therefore n = -8/3 and n = 8/3

Consider the parabola with a focus at the point (4,0) and directrix y = 3.
satela [25.4K]

Answer:

answer of your questions

Step-by-step explanation:

The process of obtaining the equation is similar, but it is more algebraically intensive. Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.

⦁ A sphere is inscribed in a cube with a volume of 27 cm3. What is the volume of the sphere?
lyudmila [28]

Answer:

≈ 14.14 cm³

Step-by-step explanation:

First find the side length of the cube.

V=S³

27=S³

∛27=∛s³

3=S

Then the volume of the sphere.

V=\frac{4}{3} × π(pi) × r³(radius cubed)

V=\frac{4}{3} × π(pi) × (1.5³)

 =\frac{9}{2}π cm³ ≈ 14.14 cm³
