Answer:

d. 78 in

Step-by-step explanation:

Perimeter of the figure = Perimeter of parallelogram - 14 + Perimeter of semicircle

= 2(21 + 14) - 14+  \frac{1}{2}  \times \pi \: d \\  \\  = 2 \times 35 - 14 +  \frac{1}{2}  \times 3.14 \times 14 \\  \\  = 70 - 14 + 3.14 \times 7 \\  \\  = 56 + 21.98 \\  \\  = 77.98 \:  \\  \\   \approx \: 78 \: in

15. a music concert is organized at a memorial auditorium. the first row of the auditorium has 16 seats, the second row has 24 s
Drupady [299]

The equation for the nth term in the arithmetic sequence is   8n + 8.

The number of people that can be accommodated in the 16th row is 136.

<h3>What is an  arithmetic progression?</h3>

Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value. It is also called Arithmetic Sequence.

Given that,

No. of seats in first row = 16

No. of seats in second row = 24

No. of seats in third row = 32

Total number of rows = 50

It forms an arithmetic progression

First term = a = 16

common difference d = 8

Number of terms, n = 50

(A) The formula for the n th term of an arithmetic progression is given by

Tn = a + (n - 1) d

    = 16 + (n-1) 8

    = 16 + 8n - 8

Tn = 8n + 8

(B) Now,

n = 16

The number of seats in 16 th row is given by

T(16) = 8 x 16 + 8

T(16) = 136 seats

Hence, (A)The equation for the nth term in the arithmetic sequence is   8n + 8. and (B) The number of people that can be accommodated in the 16th row is 136.
