Mathematics
1 answer:
Musya8 [376]4 years ago
5 0

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]

Here are the coordinates:

(60, 105)

(62, 114)

(64, 124)

(66, 131)

(68, 139)

(70, 149)

(72, 158)

Step-by-step explanation: All you have to do is take the values for y and x and plug them in to get the coordinates that you need. After doing that, use the line that you've created and find a point that would fall directly above 75, or use the line of best fit (in a scatterplot, this is a line that fits most of the points).

Hope this helps!

prisoha [69]
First, lets convert our dimensions into cm. 

2*2.54 = 5.08 cm.
1.5*2.54 = 3.81 cm.

Now, lets multiply by for the get the dimensions of the original painting in inches. 

5.08*40 = 203.2 cm
3.81*40 = 152.4 cm

Finally, lets divide our new dimensions.

203.2/2.54 = 80 in.
152.4/2.54 =  60 in.

The dimensions of the original painting is 80 in. by 60 in.
