<span>|x| is x if x>0
|x| is -x if x<0
|x| is 0 if x=0
so
(|x|)'=1 when x>0
so
(|x|)'=-1 when x<0
</span><span> (|2x-4|)'=2 when x>2
and
(|2x-4|)'=-2 when x<2
</span>
<span>Therefore the left derivative doesn't equal the right derivative as x approaches 2.</span>
Answer:
x= 16.53
Step-by-step explanation:
Since this is a right triangle we can use the law of cosine (adjacent/hypotenuse) to solve. You get the equation cos(49)=x/55. You then wanna multiply 55 to both sides so you can isolate x. You get 55*cos(49)=x. Then, you put 55*cos(49) into a calculator and multiply to get 16.5325899059.... Then round to the nearest hundredth to get 16.53 as your answer.
Hope this helps :) (its been a while since I've done trig ratios so thanks for the refresher)
Answer:
∠ BOC = 30°
Step-by-step explanation:
Given ∠ COF = 150°
∠ BOC + ∠ COF = 180° ( BF is a straight angle ) , that is
∠ BOC + 150° = 180° ( subtract 150° from both sides )
∠ BOC = 30°
Answer:
y = 2.5x + 0
