Answer: There are 53 new signs are needed.

Step-by-step explanation:

Since we have given that

Length of section of a highway = 23 miles

At every 0.5 miles in between, new signs will be placed at the beginning.

So, Number of new signs would be

\dfrac{26}{0.5}\\\\=\dfrac{260}{5}\\\\=52

And there is a new sign at the beginning too.

So, the number of new signs would be 52+1= 53.

Hence, there are 53 new signs are needed.

The answer would be 13 because if u have to put a sign every 0.5 mi you would have to divide 26 by 2

26. The cost of a television set has increased continuously by 2%. In 1999, the average
RUDIKE [14]

Answer:

<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Cost of the TV set in 1999 = US$ 400

Annual increase rate = 2% = 0.02

2. Write an exponential model to represent this data.

Cost after n years = Cost in 1999 * (1 + r)ⁿ

where r = 0.02 and n = the number of years since 1999

Replacing with the real values for 2020, we have:

Cost after 21 years = 400 * (1 + 0.02)²¹

Cost after 21 years = 400 * 1.5157

Cost after 21 years = $ 606.28

The TV set costs $ 606.28 in 2020.

<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
