The angle measure of DBC is 45
Answer: C
Step-by-step explanation:
We know that 
, and thus by the exterior angle theorem,
Thus, 
Answer:
Step-by-step explanation:
The graph of this function is that of a parabola that opens down (due to the negative coefficient of t^2). The axis of symmetry is
-b -100
x = --------- = ----------- = 50/16 = 25/8.
2a 2(-16)
The y value of the vertex is h(25/8) = -16(25/8)^2 + 100(25/8) + 10, or 166/25.
The largest value this function can take on is 166/25. Thus, the range is
(-infinity, 166/25).
Since the given function is a polynomial, the domain consists of all real numbers.
Answer
The mode is the same in both seasons.
since they both have 4 numbers that repeat themselves
42 and 21 are constants their numbers
