Answer:
Step-by-step explanation:
y=x² ln(x)sin 2x
taking log of both sides
log y=log(x² in(x)sin 2x)=log x²+log.ln (x)+log (sin2 x)
=2log x+log .ln(x)+log sin 2x
diff. w.r.t.x
1/y×(dy/dx)=2/x+(1/ln(x))×(1/x)+( 2 cos 2x/sin2x)
dy/dx=y[2/x+(1/x.ln(x))+2 cot 2x]
dy/dx=x² in(x) sin (2x)[2/x+1/xin(x)+2 cot 2x]
The answer is 300 is 10 times as much as 3000
Answer:
Option A.
Step-by-step explanation:
If I have two variables b and c and a constant of 10. I can write that problem like this:
10b = c
For example, my factory today will make 20 books:
10×20 = c
$ 200 = c
Answer: 40 cones
Explanation: If the blue cones (of which there are 10) are 25% or one quarter of the total number of cones, that means that the total number is equal to four times that, or 40.
10 = 25%
total = 100%
25% x 4 = 100%
10 x 4 = 40
