Answer:

y = x³

Step-by-step explanation:

Note that

1³ = 1 × 1 × 1 = 1 ← value of y- coordinate

2³ = 2 × 2 × 2 = 4 × 2 = 8 ← value of y- coordinate

3³ = 3 × 3 × 3 = 9 × 3 = 27 ← value of y- coordinate

4³ = 4 × 4 × 4 = 16 × 4 = 64 ← value of y- coordinate

5³ = 5 × 5 × 5 = 25 × 5 = 125 ← value of y- coordinate

The rule is that the y- coordinate is the cube of the x- coordinate, that is

y = x³

A sequence can be generated by using an = an-1 + 4, where a1 = 6 and n is a whole number greater than 1. What are the first four
Firlakuza [10]

<u>Answer:</u>

  • The first four terms are <u>4</u><u>,</u><u>8</u><u>,</u><u>1</u><u>2</u><u>,</u><u>1</u><u>6</u>

<u>Step-by-Step </u><u>Explanation</u><u>:</u>

The given relation between the nth term and it's previous term is given by:

\boxed{an = an - 1 + 4}

GiveN:

  • a1 = 4

Now finding the other three terms of the AP with the given relation.

a2 = a1 + 4

Putting a1 = 4,

a2 =  4 + 4 = 8

Now, Third term:

a3 = a2 + 4

Putting a2 = 8,

a3 = 8 + 4 = 12

Now, Fourth term:

a4 = a3 + 4

Putting a3 = 12,

a4 = 12 + 4 = 16

Hence, The first four terms of the AP is 4, 8, 12 & 16.

I need help with a math question that is 0.1x = 5/y
BabaBlast [244]
Unfortunately you have not included the directions.  Are you supposed to solve for x?  or for y?

Suppose the directions say, "Solve for x."  Then, clear out the decimal fraction by mult. both sides of the given equation by 10.  This will give you the solution, that is, a formula for x in terms of y.
