Hello,
(u*v)'=u'v+uv'
u=2x²+3 ==> u'=4x
v=sin 5x ==>v'=cos 5x *5
((2x²+3 sin (5x))'=4x* sin (5x) +(2x²+3)*cos (5x) * 5
Here you go. I hope you understand. Ask if you don't.
Answer:
Step-by-step explanation:
-2 (-x +5y ) + 3 (2x - 6y)
Opening bracket
= 2x - 10y + 6x - 18y
= 8x - 28y
= 4(2x - 7y)
Answer:
0
Step-by-step explanation:
The slope is 0 as there is no x variable within the equation.
recall y=mx+c where m is the slope. y=3 so we are only given the y intercept.
to graph this simply draw a horizontl line that crosses (0,3).
Answer: j = -0.45
Step-by-step explanation:
2.25 – 11j – 7.75 +1.5j = 0.5j – 1
We can group similar terms:
-11j +1.5j -0.5j = -1 - 2.25 + 7.75
-10j = 4.5
j = 4.5/-10
j = -0.45
Answer: j = -0.45
