Answer:  \bold{(A)\ a_n=7n-2}

<u>Step-by-step explanation:</u>

The explicit rule for an arithmetic sequence is: a_n=a_1+d(n-1)\quad \text{where}\ a_1\ \text{is the first term and d is the difference}

In the sequence provided {5, 12, 19, ... }, the first term is 5 and the difference (d) is 12 - 5 = 7

a_n=5+7(n-1)\\.\quad=5+7n-7\\.\quad=7n-2

Vlad1618 [11]

Answer:

Aaron travelled about 9 feet underwater

Step-by-step explanation:

We need to work with the information we are given in the question.

there are two stages of Aaron's travel. the first distance was in the air, and the second distance was in the water.

We are given both the total distance travelled and the distance travelled in the air.

To get the distance travelled in water, we subtract the distance travelled in the air from the total distance.

This will be 52 feet - 43 feet = 9 feet

Hence Aaron travelled about 9 feet underwater

Explanation;


Sales tax is computed as the product of the price times the tax rate in % divided by 100:


  • Sales tax = price × tax rate / 100

Here is each compute:


  • $299 × 4% = $299 × 4/100 = $11.96
  • $6,750 × 7% = $6,750 × 7/100 = $ 472.50
  • $76.50 × 5.2% = $76.50 × 5.2/100 =  $3.98
  • $18.32 × 3.9% = $18.32 × 3.9/100 = $0.71
  • $5.95 × 6.2% = $5.95 × 6.2/100 = $0.37
  • $13.89 × 4.3% = $13.89 × 4.3/100 = $0.60
  • $768.43 × 3.7% = $768.43 × 3.7/100 = $28.43
  • $6.49 × 5.8% = $6.49 × 5.8/100 = $0.38
  • $23.86 × 7.1% = $23.86 × 7.1/100 = $1.69
  • $12.98 × 3.9% = $0.51
