Step-by-step explanation:
it is all of the side lengths of the four sides times how many trapezoids there are
The width of a room can be from around 15 cm to about 40 cm.
meaning 1 m
and about less than 1/6 of a km
Hope it helped!
We have that
sin ∅=-0.7660
the sin ∅ is negative
so
∅ belong to the III or IV quadrant
but
180°< ∅ < 270°
hence
∅ belong to the III quadrant
sin ∅=-0.7660
sin² ∅+cos² ∅=1
cos² ∅=1-sin² ∅------> cos² ∅=1-(0.7660)²-----> 0.4132
cos ∅=√0.4132-----> cos ∅=0.6428
the value of cos ∅ is negative-------> III quadrant
cos ∅=-0.6428
tan ∅=sin ∅/ cos ∅----> tan ∅=-0.7660/-0.6428----> tan ∅=1.1917
the answer is
tan ∅ is 1.1917
Answer:
Step-by-step explanation:
Using the formula for the exponential decay that is 
, we have N=
, 
and k=0.1374.
Thus, becomes
Taking log on both sides, we get
