After allowing 20% discount on the marked price with 13%

saveliy_v [14]

Answer:

The marked price of the article is 22,600

Explanation: 

Given, selling price of an article SP = Rs. 18080

To calculate marked price MP, the formula used is

$\mathrm{SP}=\mathrm{MP}\left(1-\frac{D \%}{100}\right)$

Discount D = 20%

Substituting the given values

SP = $\mathrm{MP}\left(1-\frac{20}{100}\right)$

18080 = $\mathrm{MP}\left(1-\frac{1}{5}\right)$

$18080=\mathrm{MP}\left(\frac{4}{5}\right)$

$\mathrm{MP}=\frac{18080 \times 5}{4}$

MP = Rs. 22,600

Therefore the marked price of the article is 22,600

A particle moves on a coordinate line with an acceleration at time t seconds of e^t/2 m/sec^2. At t=0 the particle is at the ori

castortr0y [4]

Hello,

A) $a=e^ \frac{t}{2} \\\\

v(t)=\int\ a\ dt=\int\ e^ \frac{t}{2}\ dt=2*e^ \frac{t}{2}+C\\\\v(0)=-4\\
 2*e^ \frac{0}{2}+C=-4\\
 C=-6\\\\

\boxed{v(t)= 2*e^ \frac{0}{2}-6}\\\\



$

B)
$2*e^ \frac{t}{2}-6=0\\\\

e^ \frac{t}{2}=3\\\\

t=2*ln(3)\approx{2,19722...}\\

$

C)

$x(t)=\int_0^6(2*e^ \frac{t}{2}-6})\ dt=\left[4*e^ \frac{t}{2}-6t\right]_0^6\\\\ =e^3-36-4=4e^3-40\approx{40.3421...}\\\\$
