Answer: 54
Step-by-step explanation: 30, percentage increased by 80% (percent) of its value = 54
The Solution:
Given:
We are required to find the area of the sector GPH.
The formula for the area of sector GPH is:

Substitute these values in the formula.

Therefore, the correct answer is:
Answer:
Domain of the given function is all real numbers and the range of the function all real numbers.
Step-by-step explanation:
The given function is
.... (1)
The slope intercept form of a line function is
.... (2)
Where, m is slope and b is y-intercept.
From (1) and (2), we get

It means the slope of the line is -5 and y-intercept is 4.
Draw a line with slope -5 and y-intercept 4 on a coordinate plane as show below.
Domain is the set of inputs and range is the set of outputs.
The function is defined for all values of x. So, the domain of the function is all real numbers.

The value of function can be any real number. So, the range of the function is all real numbers.

Therefore, the domain of the given function is all real numbers and the range of the function all real numbers.
