The relationship between the rates of change can be found by taking the derivative of area with respect to time.
... a(t) = π·r(t)²
... a'(t) = 2π·r(t)·r'(t)
At the time of interest, we have
... a'(t) = 2π·(6 ft)·(5 ft/min) = 60π ft²/min
The rate of change of area at that time is 60π ≈ 188.5 ft²/min.
Step-by-step explanation:
is given
definition of <u>bisect</u>
<u />
are both given
<u />
definition of perpendicular
because all right angles are congruent
vertical angles are congruent
ASA (angle-side-angle)
CPCTC (corresponding parts of congruent triangles are congruent)
The area is 100 because 15*B(9)=100
Answer:
q = 6
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The first one is 64, the second 250, the third 520, and the fourth is 96
