Answer:

3053.63

Step-by-step explanation:

Use the equation for sphere volume: V=\frac{4}{3}\pi r^3

Plug the values in and get V=\frac{4}{3}\pi 9^3=3053.62805929

≈ 3053.63

Note: exact value of pi used.

İn the system equations above, n is a constant. İf the system has no solution, what is the value of n
jarptica [38.1K]

Answer:

  • n = - 6

Step-by-step explanation:

<u>Given is the system of linear equations:</u>

  • nx + 3y = 6
  • 12x - 6y = 0

<u>Convert both equations into slope intercept form:</u>

  • nx + 3y = 6 ⇒ 3y = - nx + 6 ⇒ y = - 1/3nx + 2
  • 12x - 6y = 0 ⇒ 6y = 12x ⇒ y = 2x

<u>The system has no solution if lines have equal slopes with different y-intercepts:</u>

  • -1/3n = 2
  • n = - 6

How many solutions does the following equation have? 10x-1=10x+4
zimovet [89]
  • Your answer is no solution.
  • Because if we transpose 10x to the left hand side with a change in the symbol, then it will become 0.
  • 10x - 1 = 10x +4
  • or, 10x - 10x = 4 + 5
  • or, 0 = 9
  • Hence, the equation has <em><u>no solution</u></em>.

Hope you could get an idea from here.
