Answer:
C
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=x+1 and y=-x+2. The line y=-x+2 continues to the right and has an open circle at the end. So this point is not included. This means the interval is a greater than sign but not equal to. This means C is the answer.
Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle = 
⇒ area = 
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²
Answer: 1.27 in
Step-by-step explanation:
100= 16 (3.14 (2.5/2)^2 x t)
