Plz see attachment below

Step-by-step explanation:

Table I

Given function is,

f(x) =

From the table attached,

For x = 0.827, value of function f(0.827) = 5,

f(0.827) =

Therefore,

0.827[log(b)] = log(5)

log(b) = 0.8452

b =

b = 7

Therefore, function 'f' will be,

f(x) =

For f(x) = 9,

9 =

log(9) = log()

log(9) = x[log(7)]

x = 1.129

Table II

Given function is g(x) =

From the given table,

For x = 7, g(x) = 1

1 =

b = 7

Therefore, the function 'g' will be,

g(x) =

For g(x) = 1.318

1.318 =

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
