Answer:
Option a - f(x)=20x
Step-by-step explanation:
Given : For a certain function f = f(x), we know that f is proportional to x and that the constant of proportionality is 20.
To Find : A formula for f ?
Solution :
We have given that,
f is proportional to x i.e.
This implies
Where, k is the proportionality constant
The constant of proportionality is 20.
So,
On comparing with, f = f(x)
Therefore, The formula of f is
So, Option a is correct.
Let length of original garden be x m. Then:-
(x + 7)^2 = 169
x + 7 = 13
x = 13-7 = 6m
Answer 6 m.
It is 19 degrees (19 times 2 equals 38. 38+10=48
