Elevators traveling from one floor to the next do not travel at a constant speed. suppose the speed of an elevator in feet per second is
given by the function 10) = -0.54* +422 - 1212 + 16, where t is the time in seconds.
find the speed of the elevator at 2 seconds.
a. 7.5 ft/s
b. 8 fts
c
10.5 ft/s
5 fts
d.

Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

Can someone me with these two circle theorem questions asap?
