From the top down:

From the worksheet, we can take pi as roughly 3.14

1.

l = 75/360 * 2pi *4

l = 5.23 cm (nearest hundredth)

2.

l = 130/360*10pi

I = 11.34cm (nearest hundredth)

3.

l = 75/360*2pi*6

l = 7.85cm

4.

l = 45/360*2pi*3

l = 2.36 cm (nearest hundredth)

5.

l = 80/360*1400pi

l = 976.89 cm (nearest hundredth)

As your costumer increases, your list goes as follows, 12, 14, 16, 18,....
aleksandr82 [10.1K]

Answer:

1. 24

2. 10+2n where n denotes number of days.

3. 70

Step-by-step explanation:

1.

Consider the sequence: 12,14,16,18,...

Here,

14-12=2\\16-14=2\\18-16=2

Take the common difference as d = 2 and the first term as a = 12

Use the formula: a_n=a+(n-1)d

To find expected gain at the end of the week, find a_7

a_7=12+(7-1)2\\=12+6(2)\\=12+12\\=24

2.

Yes, the gain shows the pattern.

Put a=12,d=2 in a_n=a+(n-1)d

a_n=12+(n-1)2\\=12+2n-2\\=10+2n

Here, n denotes number of days.

3.

To find expected gain at the end of 30  days, put n=30 in a_n=10+2n

a_{30}=10+2(30)\\ =10+60\\=70
