valentina_108 [34]

$\bf \begin{cases}
x=e^t-9\\\\
y=e^{2t}
\end{cases}\\\\
-----------------------------\\\\
x=e^t-9\implies x+9=e^t\implies ln(x+9)=ln(e^t)
\\\\\\
ln(x+9)=\underline{t}\\\\
-----------------------------\\\\
y=e^{2t}\iff y=e^{2\underline{ln(x+9)}}$

Which number has an absolute value that is equal to the absolute value of 32?

pshichka [43]

1. Observe problem

Solve for the area and Circumference of a circle who's radius is 3 cm

Area for circle formula:

pi*r^2=

9pi

I simplicity is needed, 9 pi is around

28.2743338823cm^2

Circumference for circle formula: 2*pi*r

which is

6pi

if simplicity is again needed, its around

18.8495559215cm
