What is the 32nd term of 311, 305, 299
nata0808 [166]

Answer:

503

Step-by-step explanation:

For an arithmetic sequence, the n-th term is found by

a_n = a_1 + (n - 1)d

To find d (the common difference) we can simply subtract one of the terms by the last, for example:

d = 299 - 305 \\d = -6 \\

The common difference must be the same throughout the entire sequence, so we can do it once more just to be sure:

d = 305 - 311\\d = -6

We also have to know that a_1 stands for the first term of the sequence, which in this case is 311.

Now that we know this, let's find the 32nd term

a_{32} = 311 + (32 - 1)-6\\a_{32} = 311 + 192\\a_{32} = 503

Good luck!

(6,3*10^-2)÷(2,1*10^4​
nexus9112 [7]

Answer:

  • 3*10^{-6} or 0.000003

Given expression:

  • (6.3*10^{-2}) : (2.1*10^4)

Simplify it in steps below:

  • (6.3*10^{-2}) : (2.1*10^4) =
  • (6.3 :2.1)*(10^{-2}:10^4)=
  • 3*(10^{-2-4})=
  • 3*10^{-6} or 0.000003

<u>Used properties:</u>

\cfrac{ab}{cd}=\cfrac{a}{c}*\cfrac{b}{d}

a^b:a^c=a^{b-c}

a^{-b}=1/a^b

Postulate: If two lines intersect, then they intersect in exactly one point. true or false
ololo11 [35]

Answer:

Step-by-step explanation:

The given postulate If two lines intersect, then they intersect in exactly one point is true because whenever the two lines intersect they intersect at one point only and we know that a postulate  is a statement that we accept without proof.

The given theorem If two distinct planes intersect, then they intersect in exactly one line is true as theorem is a statement that has been proved and it has been proved that if  two distinct planes intersect, then they intersect in exactly one line.

The figures are drawn to prove them.
