First find the secant line. The slope of the secant line through
(when
) and
(when
) is the average rate of change of
over the interval
:
The tangent line to
will have a slope determined by the derivative:
Both the secant and tangent will have the same slope when
, or when
.
Answer:
What line are you talking about?
Step-by-step explanation:
What line are you talking about?
i think it is a function.
Generally, the x-intercept occurs when y = 0; in this case, x represents the number of hours after opening and y represents the number of cups of coffees sold, so when y = 0, it means that there were no cups of coffee sold, thus B is the correct answer.
Answer:
12.566
Step-by-step explanation:
A = ∫1/2(r)^2dtheta from a - b = 0 to 2π
∫1/2(sin^2theta-4sintheta+4)dtheta
[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…
when you solve this you get 14.137 without taking out the cos(2theta+3)
