Answer:
18:162
Step-by-step explanation:
1:9
1+9=10
(1×180)÷10= 18
(9×180)÷10=162
The answer would be D, as it is the closest option.
Answer:
0.167
Step-by-step explanation:
Note that 3/18 reduces to 1/6. 1/6 is a rational number whose decimal equivalent is repeating: 1/6 = 0.166666 ...
It appears that answer choices A and D are identical, as arer B and C. You might want to verify that you've copied down the answer correctly.
Answers A and D (identical) are the best choices here, due to less rounding off.
The value of a, b and c can be calculated using the inverse function.
The calculated the value of a= 2, b=1 and c= -2.
Given:
The function is
and its inverse is
.
<h3>What is an inverse function?</h3>
- The inverse function of a function is defined if
is a function that undoes the operation of
.
- The inverse of
exists if and only if
is bijective, and if it exists, is denoted by
.
Substitute the value of x= -1 in a given inverse function and calculate the value of a.

Substitute the value of x is 0 in given inverse function.

Substitute the value of x is 2 in given inverse function.

Therefore, the value of a= 2, b=1 and c=-2.
