the direction angle for vectors 135° the X component of the vector is -3 what is the Ywhat is what what is the Y component of th
blagie [28]
Well, the X component (assuming x is the horizontal) is equal to RCosZ

Where Z is the angle and R is the size of the resultant

Substitute into formula :

X component = RcosZ
-3 = Rcos135°
R = -3/cos135°
R = 4.24264...
R = 4.24 (2dp)

The vertical component (or Y component) is equal to RSinZ

Vertical component = RSinZ
= 4.24264... × Sin135°
= 3

The answer is 3

Answer:

2x +21

Step-by-step explanation:

log_{5} {5}^{(2x - 9)}   +  log_{3} {729}^{5}   \\  \\  =  log_{5} {5}^{(2x - 9)}   +  log_{3} {( {3}^{6} )}^{5}   \\  \\  =  log_{5} {5}^{(2x - 9)}   +  log_{3} { {3}}^{6 \times 5}   \\  \\  =  log_{5} {5}^{(2x - 9)}   +  log_{3} { {3}}^{30}    \\  \\ =(2x - 9)  log_{5} {5} + 30 log_{3} { {3}}   \\  \\  = (2x - 9).1 + 30(1 )\\ ( \because \: log_{a} { {a}}    = 1) \\  \\  = 2x - 9 + 30 \\  \\  = 2x +21
