that answer is 7 is bigger then 1.9
Step-by-step explanation:
so 7 is a whole and 1.9 is a decimal
Answer:
The answer is C.
Step-by-step explanation:
Answer:
dh/dt ≈ 0.55 ft/min
Step-by-step explanation:
The volume is given by the formula ...
V = (1/3)πr²h
We have r = h/2, so the volume as a function of height is ...
V = (1/3)π(h/2)²h = (π/12)h³
Then the rates of change are related by ...
dV/dt = (π/4)h²·dh/dt
dh/dt = (4·dV/dt)/(πh²) = 4(35 ft³/min)/(π(9 ft)²)
dh/dt ≈ 0.55 ft/min
Recall that the characteristic polynomial of a 2x2 matrix

is

but

and

, so the characteristic polynomial for

is

We're given that the trace is 15 and determinant is 50, so the characteristic polynomial for the matrix in question is

and the eigenvalues are those

for which the characteristic polynomial evaluates to 0.
