How do i find LM? On number 2 .
Masja [62]
Given: KL is a tangent to the circle.
LM is another tangent to the circle.

We can use the tangent meeting at an external point theorem.
<em>Theorem</em>: <em>The tangent segments to a circle from an external point are equal.
</em>
Thus, we can say KL = LM, as they lie on a common circle, and are tangents to such circle.

4x - 2 = 3x + 3
4x - 3x = 3 + 2
x = 5

Since LM is 3x + 3, we can substitute the value of x to LM to render:
3(5) + 3 = 18

Thus, LM = KL = 18 units.

Answer:

  • recursive: a[1] = 7440; a[n+1] = a[n] -120
  • explicit: a[n] = 7440 -120(n -1)

Step-by-step explanation:

The sequence of amounts in Jackson's account will be ...

  7440, 7320, 7200, ...

with a first value (a1) of 7440 and a common difference (d) of -120.

The recursive formula for an arithmetic sequence is ...

  a[1] = a1

  a[n+1] = a[n] +d

For our sequence, the recursive formula is ...

  a[1] = 7440

  a[n+1] = a[n] -120

__

The explicit formula for an arithmetic sequence is ...

  an = a1 +d(n -1)

For our sequence, the explicit formula is ...

  a[n] = 7440 -120(n -1)
