A(t)= t^2/2 - 20t + k

There was a 50-day period when the number of ants in a certain hill could be modeled by the function “a” above. In the function, “k” is a constant and a(t) represents the number of ants on day number “t” for 0 ≤t ≤49. On what day was the number of ants in the hill the same as it was in day 10?

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
