Explanation Formula used: The lateral surface area of a pyramid is given by L = 1 2 ( P ) s , where p is the perimeter of the pyramid. The total surface area is calculated using the formula S = L + A where L is the lateral surface area and A is the area of the base. The volume of a pyramid is given by the formula V = 1 3 h A , where A is the area of the pyramid. Calculation: From the given figure, it is to be noted that the s = 26 cm and h = 24 cm . Also, observe that the base of the given figure is a square. Obtain the perimeter of the square of side a = 20 cm as shown below: Perimeter, P = 4 a = 4 ( 20 cm ) = 80 cm That is, the perimeter of the equilateral triangle is 80 cm. Substitute the values s = 26 cm , P = 80 cm in the formula L = 1 2 ( P ) s and obtain the lateral surface area of the pyramid as shown below: L = 1 2 ( P ) s = 1 2 ⋅ ( 80 cm ) ⋅ ( 26 cm ) = 1040 sq cm Thus, the lateral surface area of the pyramid is 1040 sq cm

The graph of f(x) is given below. Select each true statement about the continuity of f(x) at x = 1. Select all that apply: ☐ f(x) is not continuous at x = 1 because it is not defined at x = 1. ☐ f(x) is not continuous at x = 1 because lim f(x) does not exist. x+1 ☐ f(x) is not continuous at x = 1 because lim f(x) ‡ f(1). x+→1 ☐ f(x) is continuous at x = 1.

2. Consider the following argument: (a) Seabiscuit is a thoroughbred. Seabiscuit is very fast. Every very fast racehorse can win the race. .. Therefore, some thoroughbred racehorse can win the race. Let us define the following predicates, whose domain is racehorses: T(x) x is a thoroughbred F(x) x is very fast R(x) x can win the race : Write the above argument in logical symbols using these predicates. (b) Prove the argument using the rules of inference. Do not make use of conditional proof. (c) Rewrite the proof using full sentences, avoiding logical symbols. It does not need to mention the names of rules of inference, but a fellow CSE 16 student should be able to understand the logical reasoning.
