In an electrical circuit, the current is related to the power and resistance according to the rule
1 = where I represents the current (measured in amps), P represents power (measured
in watts), and R represents resistance (measured in ohms). What is the electrical power drawn by
a device that has a resistance of 15 ohms with a current of 4 amps?
correct choice is b
when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as
to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
given that ab is divided into equal parts as
ac, cd, de, ef, fg, gh, hi, ib.
from this we find that f is the midpoint of ab.
so using mid point formula we find
f = (3,7)
similarly considering fb, we get
h = mid point of fb = ((6,6) and g, mid point of fh is
g = (9/2, 13/2)
i is mid point of hb
so i =(15/2,11/2)
