List the single-digit divisors of 2100.<br> I really need help
liberstina [14]

Answer:

  • 1, 2, 3, 4, 5, 6, 7

Step-by-step explanation:

<u>Prime factors of 2100 are:</u>

  • 2100 = 2*2*3*5*5*7

<u>The single-digit divisors are:</u>

  • 1, 2, 3, 2*2= 4, 5, 2*3= 6, 7

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

<u>Another solution is you divide 2100 by all numbers 1 through 9 and list those divisible:</u>

  • 2100/1 = 2100, yes
  • 2100/2 = 1050, yes
  • 2100/3 = 700, yes
  • 2100/4 = 525, yes
  • 2100/5 = 420, yes
  • 2100/6 = 350, yes
  • 2100/7 = 300, yes
  • 2100/8 = 262.5, no
  • 2100/9 = 233.33, no

So all the numbers from 1 to 7

Is the graph a linear function, non linear function, or relation
serious [3.7K]

a LINEar function has well, the graph of a straight line, so this isn't that.

is it a relation? well, yes, because the y-value correlates with the x-value, so one depends or relates to the other.

is it a non-linear function?  well, a function has to pass the <u>vertical line test</u>, meaning if we draw vertical lines they must touch the graph only once on their way down.... and in this case it seems they do, so it is non-linear clearly, and it's also a function.

The formula below gives the sum of the degrees, S, of the interior angles of a polygon. If n represents the number of sides, whi
Helga [31]

Answer:

The equation representing the value of <em>n</em> is, n=\frac{S}{180^{\text{o}}}+2.

Step-by-step explanation:

The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:

S=(n-2)\times 180^{\text{o}}

Compute the equation of <em>n</em> as follows:

   S=(n-2)\times 180^{\text{o}}

\frac{S}{180^{\text{o}}}=(n-2)

   n=\frac{S}{180^{\text{o}}}+2

Thus, the equation representing the value of <em>n</em> is, n=\frac{S}{180^{\text{o}}}+2.
