Solution:
Given:
1) Amount of commission is 4% of merchandise sales made.
Hence,
Therefore, the amount of commission is $1112.
2) Gross pay is the total amount recevied.
Hence,
Therefore, the gross pay Donald recieved is $1702.
Since it's a right triangle you can use the Pythagorean theorem or Trig (Soh Cah Toa).
I'll just use the Pythagorean theorem : a² + b² = c²
a = 9
b = x
c = 18
9² + x² = 18²
81 + x² = 324
x² = 324 - 81
x² = 243
x = √(243)
factor 243 to find a perfect square
x = √(3*81)
x = 9√(3)<u />
Let the two functions be f(x) and g(x).
Create the sum or composite of the functions as
h(x) = f(x) + g(x).
In order to have inverses, both f(x) and g(x) should pass the vertical line test
Therefore the sum (or difference) of the two functions, h(x), will also pass the vertical line test.
Answer:
Because h(x) passes the vertical line test, it follows that the inverse of the composite function made by the original functions is also a function.
