Answer:

Y=0.1(1.25)^t is growth. Y=426(0.98)^t is decay. Y=100(1-1/2)^t is decay. Y=((1-0.03) 1/2) ^2t is decay. And y=2050(1/2)^t is decay. Hope this helps!

Find the explicit solution for:<br> dX/dt=(x-1)(2x-1), ln(2x-1/x-1)=t

LiRa [457]

$\dfrac{\mathrm dx}{\mathrm dt}=(x-1)(2x-1)$

is a separable ODE, as

$\dfrac{\mathrm dx}{(x-1)(2x-1)}=\mathrm dt$

Decompose the left side into partial fractions:

$\dfrac1{(x-1)(2x-1)}=\dfrac1{x-1}-\dfrac2{2x-1}$

Then integrating both sides gives

$\displaystyle\int\left(\frac1{x-1}-\frac2{2x-1}\right)\,\mathrm dt=\int\mathrm dt$

$\ln|x-1|-\ln|2x-1|=t+C$

Solve for $x(t)$ :

$\ln\left|\dfrac{x-1}{2x-1}\right|=t+C$

$\dfrac{x-1}{2x-1}=e^{t+C}=Ce^t$

$x-1=(2x-1)Ce^t$

$x(1-2Ce^t)=1-Ce^t$

$\implies\boxed{x(t)=\dfrac{1-Ce^t}{1-2Ce^t}}$

Travka [436]

Step-by-step explanation:

♦ Solution ♦ :-

Given Information :

The ratio of heights of the two girls = 5:7

Assumption

Consider their height be 5X cm and 7X cm

The height of the first girl = 5X cm

But According to the condition mentioned in given problem

The height of the first girl = 192 cm

=> 5X = 192

=> X = 192/5

=> X = 38.4

Therefore, X = 38.4 cm

Now the height of the second girl = 7X cm

=> 7 × 38.4 cm

=> 268.8 cm

♦ Alternative Method♦ :-

The ratio of the heights of the two girls = 5:7

The height of the first girl = 192 cm

Assume that the height of the second girl = X cm

Therefore, 5:7= 192:X

=> 5/7 = 192/X

=> 5X = 7×192

=> X = (7×192)/5

=> X = 7× 38.4

=> x = 268.8 cm

♦ Answer ♦ :-

The height of the second girl is 268.7 cm
