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)

The value of a small airplane depreciates exponentially every year after it is purchased. The value, in thousands of dollars, a(
ratelena [41]

Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.

<h3>Exponential function:</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function for the value of the airplane after t years is given by:

A(t) = 131.5(0.8)^t

Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.

Round 5984 to the nearest hundred.a) 5000 b) 5900 c) 5980 d) 5990 e) 6000
SpyIntel [72]
The answer would be E. because if the determining number (The number directly after the place being rounded to. The 8 in this case) is greater than five, you round up and drop the numbers after the place being rounded to (The hundredth's place), if it's less, the number in the place being rounded to stays the same, but you still drop the numbers after it.
