if x,y are in inverse proportion then complete the following table x= 42 y=-15 , x=30 y=-----

Answers

Answer 1

Answer:

when x=30, y = -21

Step-by-step explanation:

x = k/y

x = 42 y = -15

x = k/y

42 = k/-15

Cross product

42 * -15 = k

-630 = k

k = - 630

Find y when x=30

x = k/y

30 = -630/y

Cross product

30 * y = - 630

30y = - 630

y = - 630/30

y = -21

when x=30, y = -21

f(1)= -34

f(n)=f(n−1) - 3

Find an explicit formula for f(n).

Answers

Answer:

f(n) = -34 -3(n - 1)

Step-by-step explanation:

The explicit formula for f(n) is given below:

Given that

f(1)= -34

f(n)=f(n−1) - 3

Based on the above information

f(n) = a1 +d(n -1)

a1 = -34

d = -3

So

f(n) = -34 -3(n - 1)

This above represent an explicit formula
