<h3>Answer:  an = 6n - 15   (Choice C)</h3>

======================================================

Explanation:

This sequence is arithmetic

The first term is a = -9

The common difference is d = 6 since we're adding 6 to each term to get the next one (eg: -3+6 = 3 or 3+6 = 9 or 9+6 = 15)

Plug those values into the arithmetic nth term formula below

an = a + d*(n-1)

an = -9 + 6*(n-1)

an = -9 + 6n-6

an = 6n - 15

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

As a check, let's plug in something like n = 1

an = 6n - 15

a1 = 6*1 - 15

a1 = 6 - 15

a1 = -9

We see that the 1st term is -9, which matches the sequence given

Now let's plug in n = 2

an = 6n - 15

a2 = 6*2 - 15

a2 = 12 - 15

a2 = -3

The 2nd term is -3. This also matches.

I'll let you check the other values of n to confirm the answer.

Use yours formula to find the missing number of faces edges 15 vertices 9
Alexandra [31]

Using Euler's Formula, the number of faces is given by: 8.

<h3>What does Euler's Formula states?</h3>

It states that the number of vertices, edges and faces is related by the following equation:

V - E + F = 2.

In this problem, the parameters are given as follows:

E = 15, V = 9.

Hence the number of faces is given by:

V - E + F = 2.

9 - 15 + F = 2

F - 6 = 2

F = 8.

Help! What is the answer?
fiasKO [112]

Answer: 22.4

Explanation:

The pieces of the chords multiply together to get the same result. This is from the intersecting chord theorem.

The first chord has pieces of 10 and x, which multiply to 10*x

This is equal to the other product found by multiplying the pieces 14 and 16 (from the other chord)

10*x = 14*16

10x = 224

x = 224/10 ... divide both sides by 10

x = 22.4
