Answer:
3/2
Step-by-step explanation:
-3/8÷-1/4
=-3/8×-4 (Reciprocal)
=1.5
11 minutes = 1 km
11 x 5 = 55 minutes
1 x 5 = 5 km.
She can walk 5 km in 55 minutes.
Evaluating the tangent function for the two values we obtain the following:
tan 135=tan(135+180)=tan 315=-1
next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive
