Answer 1

Answer: 1. d) The number of people receiving a newspaper on a given day is 3 times what it was the previous day.

2.d) V(B) = 10B

Step-by-step explanation:

1. Since, given function, $n(d)= 4\times 3^{d-1}$Which is defined  the number of people who receive a newspaper on day d in a delivery schedule.

In first day d=1 so number of people, $n(1)= 4\times 3^{1-1}=4$

In Second day d=2 so number of people, $n(2)= 4\times 3^{2-1}=3\times 4$

In third day d=3 so number of people, $n(3)= 4\times 3^{3-1}=3\times 12$

In fourth day d=4 so number of people, $n(4)= 4\times 3^{4-1}=3\times 36$

Thus from the above explanation, we can say that everyday the number of newspaper are increasing by 3 times of the previous day.

Therefore, Option D) is correct.

2.Here,  The function V = Bh gives the volume of a cylinder whose base has an area of B square units and whose height is h units.

If h= 10

Then V= 10B

Therefore V is dependent on the value of B

Thus, Required volume, V(B)= 10B

So, Option D) is correct.

Answer 2

#1. a) Deliveries were made for 3 days. 
It is a because the value in front of d is the number of days since d is days.
#2 d) V(B)=10B
It is d because V(B) means that you are plugging in the value of B times 10  to find the volume.
