Answer:

  • triangle
  • square
  • hexagon
  • dodecagon

Step-by-step explanation:

The 12 points marked can be divided into this many equal-size groups:

  3, 4, 6, 12

so the figures that can be constructed are ...

  • triangle . . . . connects every 4th mark
  • square . . . . . connects every 3rd mark
  • hexagon . . . .connects every other mark
  • dodecagon . . connects every mark

_____

12 is also divisible by 1 and 2, but the minimum number of vertices in a regular polygon is 3.

Newton uses two properties ti rewrite the expression (4x23)x25 identify the properties he used why would Newton use these proper
valentinak56 [21]

The two properties newton used to rewrite the <em>expression </em>are;

<u><em>- Associative Property; Because it involves change of grouping of numbers in the expression.</em></u>

<u><em>- Distributive Property; Because it involves distribution of a number outside a bracket to numbers inside that same bracket.</em></u>

  • This involves algebraic <em>properties</em>. There are 3 major types that work on only addition and multiplication namely;

- Associative Property

- Commutative Property

- Distributive Property

Let us define each of them;

1) Associative Property; This property in algebra is one that means that no

matter how we group the numbers, we will still get the same result. e.g.

x + (y + z) = (x + y) + z.

2) Commutative Property; This property means that we can change the

order of <em>operation</em> and still get the same answer. For example;

p × q × r = p × r × q

3) Distributive Property; This property means that multiplying the sum of

two or more which are in a bracket by a number outside the will be equal to

the answer gotten when we multiply each number in the bracket

individually by the number outside and then adding their respective

products together. For example; p(q + r) = (p * q) + (p * r)

Newton has the expression; (4 × 23) × 25

Since it is multiplication, he can use any of the three properties above but let us use the <em>associative and distributive properties </em> as they are most suited to this expression<em>.</em>

  • For the <em><u>associative property</u></em> as shown above, he will arrive at;

(4 × 23) × 25 = 4 × (23 × 25)

  • For the <u><em>distributive property</em></u> as shown above, he will arrive at;

(4 × 23) × 25 = (25 × 4) + (25 × 23)

If r = 4 and a6 = 192, what is the first term of the sequence?
blagie [28]

Answer:

Answer: Option c. 0.1875 is the first term of the sequence.

Step-by-step explanation:

In this question sixth term of a sequence is given as A(6)= 192

Ratio of terms is given as 4

And we have to calculate the first term of the sequence.

As per formula A(n) = A(1)×r^{n-1}

                         A(6) = A(1)(r)^{6-1}

                          192 = A(1)4^{5}

                           A(1) = \frac{192}{4^{5} }

                                 = 192/1024

                                 =0.1875

So the first term of the sequence will be 0.1875
