Answer: B.
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse of a triangle is times the leg. If the hypotenuse is 16, and x is the leg, then x is , or .
Robert is incorrect: Surface are of A is 30 + 30 + 42 + 42 + 35 + 35 = 214 square centimeters. Surface area of B is 120 + 120 + 168 + 168 + 140 + 140 = 856 square centimeters. B's surface area is 4 times as great as A's.
Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
Domain is , and when . So the range is , that is,
Inverse function:
Exchanging x and y
The inverse function is
Domain:
Range of the original function is , so the domain of the inverse function is . The correct answer is given by option B.
