The length of a rectangle is 3b + 2 and the width is 9b + 6. What is the ratio of its length to its width?

Answers

Final answer:

The length to width ratio of the rectangle with length 3b + 2 and width 9b + 6 is 1:3.

Explanation:

The length and width of the rectangle are given as algebraic expressions, 3b + 2 (length) and 9b + 6 (width). To find the ratio of the length to the width, you would divide the length by the width:

Ratio = (length) / (width)= (3b + 2) / (9b + 6),

which simplifies to 1/3 after dividing both parts of the ratio by 3. Therefore, the ratio of the length to width of the rectangle is 1:3.

Lim -> 0 sin(2x) /(x*cos(x) )

help

Answers

sin (2x) can be written like:sin (2x) = 2sin(x)cos(x)
substituting this expresion in the original one:sin(2x) /(x*cos(x) =2sin(x)cos(x)/x*cos(x)=2sinx/x
taking limits, and noticing that lim as x->0 of sinx/x=1:lim 2sinx/x=2*1=2x->0
