Hi there,
5n - 9 + 4n + 5
5n - 4n = 5 + 9
Hence, N = 14
Hope this helps :)
Answer:
a horizontal line
Step-by-step explanation:
The hyperbola opens vertically, so the directrix is a horizontal line (a different one for each branch).
The equation for volume of a sphere is (4/3)(pi)(r)^3. So you would plug in he radius 9 into the equation. It would simplify to equal (4/3)(pi)(729). It simplifies further to equal (972)(pi)
My best guess is a 1/225 chance in guess the right combination
Cos=adjacent/hypotenuse
Cos30=x/20
x=cos30 *20
Sorry I don’t have a calculator right now
