Sina - (cosa)(tanb)/cosa + (sina)(tanb)
sina ≡ (tana)(cosa)
(tana)(cosa) - (cosa)(tanb)/cosa + (tana)(cosa)(tanb)
= cosa(tana - tanb)/cosa(1 + tanatanb)
(cosas cancel out)
= (tana - tanb)/(1 + tanatanb) ≡ tan(a-b)
Answer:
Step-by-step explanation:
178-10+3(25+1)2
We need to use order of operation (Pemdas).
P-Parenthesis
e-Exponents
m- Multiplication
d- Division
a- Addition
s-Subtract
178-10+3(25+1)2
178−10+3(25+1)(2)
=168+3(25+1)(2)
=168+(3)(26)(2)
=168+(78)(2)
=168+156
=324
The answer chooses give are not close to 324 but we need to pick a expression tat is equivalent.
Equivalent means equal in value.
None of these answer choose are equal to 324
Start of by trying to make 4w the subject of the equation. + 15 to each side making the equations 4w= 15+17, (15+17=32) 4w= 32 meaning that w= 8 because all you do is divide each side of the equation by 4 . HOPE THAT HELPS . if you need more help just shout me
Answer:
Slope is 5/4
Step-by-step explanation:
<u>Slope is change in y over change in x</u>
<u />
Change in y is 5
Change in x is 4
Slope = 5/4
Answer: Slope is 5/4
The slopes of parallel line are the same.
We have therefore the equation of parallel line is
We know. The line passes throught (4; -2). Substitute the coordinates of the point to the equation:
