Korvikt [17]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

p= amount at any time

then $\frac{dp}{dt}=0.07 p$

$p=p_0 (1+e^{0.07 t) \\\\$

$P_0=\ principle \ amount \\\\ interest \ =p-p_0=p_0e^{0.07t}\\\\ p=y\frac{dy}{dt}=0.07y_0$

at time $= t\ years$

$\frac{dp}{dt}\\\\c_0=\$ \ 20000\ year\\\\p \to p+dp\\\\ dp=0.07p+c_0$

y= amount at any times

$\frac{dy}{dt}=0.07y+c_0\\\\dt= \frac{dy}{c_0+0.07y}$

For point a:

$\frac{dy}{dt}=20000+0.07 y$

For point b:

$\frac{dy}{20000+0.07 y}=dt\\\\\frac{1}{0.07}|n(\frac{0.07y+20000}{20000})=t\\\\\frac{0.07y}{20000}+1=e^{0.07t}\\\\y=7.1428\times 10^4[e^{0.07t} -1]\\\\y=\frac{20000}{0.07}[e^{0.07t}-1]\\\\$

For point c:

$y(30)=827391.75$

Find the perimeter of the given triangle

faltersainse [42]

ABC is similar to PQR

that means AC/PR is a constant = 12/ 6 = 2

AC= 2 PR

AB= 2PQ

BC= 2QR

Perimeter of ABC= AB+BC+ CA=

2PQ + 2 QR + 2PR= 2( PQ+ QR+ PR)

= 2( perimeter of triangle PQR )

Perimeter of ABC= 2( perimeter of PQR) = 2* 36 = 72

Answer : 72.
