Answer:
6xy(15xy−1)
Step-by-step explanation:
Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
Answer:
-1/6
Step-by-step explanation:
I looked it up
(3x19.95+23.5+124.95)1.05=
59.85+23.5+124.95 =208.3
208.3×1.05=218.715
Answer is B
-0.6- (-0.4)= -0.6+0.4= -0.2
