Write r=-8sec(theta) in rectangular form

Airida [17]

$r=-8\sec\theta=-\dfrac8{\cos\theta}\implies r\cos\theta=-8$

Converting from rectangular coordinates to polar coordinates involves setting $(x,y)=(r\cos\theta,r\sin\theta)$ . Since the left hand side matches $x$ perfectly, the equation's rectangular coordinate form is $x=-8$ .

Which shows a correct order to solve this story problem?

denis23 [38]

If you would like to solve the above problem, you can do this using the following steps:

1.2 miles * 7 days = 1.2 * 7 = 8.4 miles ... Multiply 1.2 by 7.
2.4 miles * 7 days = 2.4 * 7 = 16.8 miles ... Multiply 2.4 by 7.
8.4 miles + 16.8 miles = 25.2 miles ... Add the two products.

The correct result would be A.
