Answer:

50.2 m²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius , here r = 4 ), thus

A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )

If the measure of BEC is (2x+3) and x=30, which expression could represent the measure of AED?
Rufina [12.5K]

Thats means angle BEC is 63. By the vertical angle theorem AED is the same. 3x-27 when x=30 is also 63.

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)
