Answer:
To solve the above riddle, you just need to think creatively and not take the question literally. The answer to the above riddle is, "Four kids get an apple and the fifth kid gets an apple still in the basket." This way, everyone gets an apple and the last apple still stays inside the basket.
Answer:
b² = a² + c² - 2ac cos B
Step-by-step explanation:
The cosine rule can be use when you are given three sides of a triangle and ask to find any angle or when you are given two sides and a included angles(the angle between the two sides given) and ask to find the length of a side.
The equation Sophia can use to solve for the side length(b) of a triangle when given two length and the included angle can be expressed below. Sophia was given two sides and an included angle and was asked to find a side length b.
For sides a, b and c the cosine rule can be represented below
a² = b² + c² - 2bc cos A
b² = a² + c² - 2ac cos B
c² = a² + b² - 2ab cos C
The equation required base on your question is
b² = a² + c² - 2ac cos B
Based on the graph I attached, the best answer is
OPTION B.
It is a function because it passes the vertical line test (which means the answer cant be A or C) and it fails the horizontal line test which means it is NOT one-to-one but instead many-to-one
