Step-by-step explanation:
The first step is to determine the composite function;
We then employ a graphing utility to determine the range and the domain of the new function.
The range is the set of y-values for which the function is defined. In this case it is;
On the other hand, the domain refers to the set of the x-values for which the function is real and defined. In this case; it is the set of real numbers x except x does not equal npi for all integers n.
Answer:
given - a rectangle ABCD
AB = 40
AC. = 90
BC = ?
in triangle ABC
using Pythagoras theorem
(AB) ² + (BC) ² = (AC) ²
(40)² + (BC) ² = (90)²
(BC) ² = (90)²- (40)²
(BC) ² = 8100 - 1600
(BC) ² = 6500
BC =
