If a varies directly as the cube root of B and if a equals to 3 when B equals to 64 find the formula connecting the variables he
Brrunno [24]

Answer:

a=k1\sqrt[3]{B}

B=125

Step-by-step explanation:

Given :

a=3

B=64

According to question

a ∝ \sqrt[3]{B}

therefore

a=k1 \sqrt[3]{B}........Eq(1)

K1=\frac{a}{\sqrt[3]{B} }......Eq(2)

Putting the value of a and B we get in Eq(2) we get

K1=\frac{3}{4}

Putting the value of k1 in Eq(1)

a=\frac{3}{4}\sqrt{B} .......................Eq(3)

putting the value of a=15/4 IN Eq(3) we get

\frac{15}{4}\ =\frac{3}{4} \sqrt[3]{B}  \\\\\sqrt[3]{B}\ =\ 5\\Cubing\  both\  side\  we\  get\\B=125

In Section 1.3 we saw that the autonomous differential equation m dv dt = mg − kv, where k is a positive constant and g is the a
Thepotemich [5.8K]

Answer:

\lim_{t \to \infty} v = \frac{mg}{k}

Step-by-step explanation:

Firstly its necessary to put the autonomous DE in its normal form to get

\frac{dv}{dt} = g - \frac{kv}{m}

To get the critical point we solve

g - \frac{kv}{m} = 0

\frac{kv}{m} = g--> v = \frac{mg}{k}

The critical point is v = \frac{mg}{k}

\frac{dv}{dt} > 0 for v < \frac{mg}{k}

and

\frac{dv}{dt} < 0 for v > \frac{mg}{k}

from the phase portrait we observe that the critical point

v = \frac{mg}{k}  is stable

\lim_{t \to \infty} v = \frac{mg}{k}
