Mathematics

Sergeeva-Olga [200]3 years ago
6 0

Answer:

time taken=1800 seconds

Step-by-step explanation:

velocity=v=10m/s

distance=S=18km=18×10³m=18000m

t=?

as we know that

velocity=\frac{distance covered}{time taken}

velocity×time taken=distance covered

now here we have to find time

time taken=\frac{distance covered}{velocity}

time taken=\frac{18000m}{10m/s}

time taken=1800seconds

What two numbers add to be 6 and multiply to be 15
yarga [219]
   
\displaystyle \bf \\
x_1+x_2=6\\\\
x_1\cdot x_2=15\\\\
\Longrightarrow~~x^2-6x+15=0\\\\
x_{12}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{6\pm\sqrt{36-60}}{2}=\\\\
=\frac{6\pm\sqrt{-24}}{2}=\frac{6\pm2\sqrt{-6} }{2}=3\pm i\sqrt{6}\\\\
x_1=\boxed{3-i\sqrt{6}}\\\\
x_2=\boxed{3+i\sqrt{6}}\\\\
\texttt{Verify:}\\\\
x_1+x_2=3-\underline{i\sqrt{6}}+3+\underline{i\sqrt{6}}=3+3=6~~correct\\\\
x_1\cdot x_2=(3-i\sqrt{6})(3+i\sqrt{6})=3^2-(i\sqrt{6})^2=9+6=15~~correct
