Hello,
tan (t)<0
==> sin (t) /cos (t)<0
==>1 / cos (t)<0 [since sin (t) ≠0, dividing by sin (t) ]
==> cos (t) <0
I just answered a so let's start with b :
______________________________
b. The equivalent resistance of series
resistances is equal to their sum
Thus :
equivalent resistance = 480 + 360
equivalent resistance = 840
_______________________________
c.
I = V ÷ R
I = 120 ÷ 840
I = 0.1428 A
_______________________________
d. 0.1428 A
_______________________________
e. 480 ===》 120 - ( 480 × 0.1428 ) =
120 - 68.544 =
51.456
360 ===》 120 - ( 360 × 0.1428 ) =
120 - 51.408 =
68.592
_______________________________
f. 480 ===》68.544 lower than battery
360 ===》 51.408 lower than battery
Im not sure which number is underlined, but here is each number's place:
7 is tenths
2 is hundredths
4 is thousandths
Answer:
it's difficult to answer..sorry
