Answer:

(I) 0.1n2+7.7n-7.8

(2) 8.2cm

Step-by-step explanation:

Answer:

[tex]S_{n-1}=0.1n^2 +7.7n - 7.8[/tex]

The diameter of the roll when one sheet is rolled over = 8.2cm

Step-by-step explanation:

(i) Given [tex]S_n = 0.1n^2 + 7.9n[/tex]

To find [tex]S_{n-1}[/tex], substitute the value of ‘n’ as ‘n-1’ in the above equation

Then,

[tex]S_{n-1} = 0.1(n-1)^2 + 7.9(n-1)[/tex]

= [tex]0.1(n^2 -2n+1) +7.9n-7.9[/tex]

=[tex]0.1n^2 -0.2n+0.1 +7.9n-7.9[/tex]

=[tex]0.1n^2 +7.7n - 7.8[/tex]

Hence, [tex]S_{n-1}=0.1n^2 +7.7n - 7.8[/tex]

(ii) Given,

Diameter of the core = the first term of the AP = [tex]a_1[/tex]

Twice the thickness of the paper  = common difference= d

When one sheet of paper is rolled over the core,

Then the new diameter of the roll = [tex]a_1+d[/tex], the second term of the AP([tex]a_2[/tex])

To find [tex]a_2[/tex]

We have [tex]S_n = 0.1n^2 + 7.9n[/tex]

[tex]S_1 = first term = a_1 = 0.1x1 +7.9 = 0.1+7.9 = 8[/tex]

[tex]S_2 = a_1 + a_2[/tex]

[tex]0.1 x 2^2 + 7.9 x2 = 8 +a_2[/tex]

[tex]0.4+15.8 = 8+a_2[/tex]

[tex]16.2 = 8+a_2[/tex]

[tex]a_2 = 8.2[/tex]

Hence, the diameter of the roll when one sheet is rolled over = 8.2cm

Answer:

by supporting greater numbers of connected devices

The ways in which 5G technology enhances the Internet of Things (IoT) are:

• According to the reports, 5G is more than 10 times the speed of Long term Evolution (LTE) networks.
• This speed will increase the capability of IoT devices to connect and transfer data fast. For example, if we consider smart home devices, the increased speed helps to improve the overall speed of the network when connected devices receive and send data and notifications.
• Along with smart home devices, almost all IoT devices will get benefited rapidly, including all those devices with Hospital, health-care and industrial applications.

Hence, these are the ways in which 5G technology enhances the Internet of Things (IoT).
