Convert the complex number z = -12 + 5i from rectangular form to polar form.​
Paha777 [63]

Answer:

z=13(\cos 157\degree +i\sin157\degree)

Step-by-step explanation:

The given complex number is

z=-12+5i

The polar form of this complex number is;

z=r(\cos \theta +i\sin \theta), where

r=\sqrt{(-12)^2+5^2}

r=\sqrt{144+25}=\sqrt{169}=13

and

\theta =\tan^{-1}(\frac{5}{-12})

This implies that;

\theta=157\degree to the nearest degree.

Hence the polar form is

z=13(\cos 157\degree +i\sin157\degree)

Fred is running on the school track. He can run 10 3 4 laps in 4 5 of an hour. How many laps can Fred run in one hour?
Triss [41]

Answer:

13\frac{7}{16} laps can Fred run in one hour.

Step-by-step explanation:

Given Statement: Fred is running on the school track. He can run 10\frac{3}{4}  laps in \frac{4}{5}  of an hour.

Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates

From the given condition we have;

In \frac{4}{5} he can run \frac{43}{4} laps

Unit rate per hour = \frac{\frac{43}{4} }{\frac{4}{5} }

                              =\frac{43}{4} \times \frac{5}{4} = \frac{215}{16} laps

Therefore, Fred can run in one hour is, 13\frac{7}{16} laps.
