How can you use a distance time graph to compare the motion of two different object
tia_tia [17]

Answer:

If an object moves along a straight line, the distance traveled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

Find dy/dx when y = Ln (sinh 2x). A. 2 cosh 2x B. 2 sech 2x C. 2 coth 2x D. 2 csch 2x
givi [52]
The function given is a composite function. Let's work from the outside in:
y=(ln(sinh(2x)))

First step:
\frac{d}{dx}[y]= \frac{d}{dx}[ln(sinh(2x))]

Now, let's work it out:
\frac{dy}{dx} = \frac{1}{sinh(2x) } *   \frac{d}{dx}[sinh(2x)]

Next step:
\frac{dy}{dx} = \frac{1}{sinh(2x) } * cosh(2x) *  \frac{d}{dx}[2x]

Next step:
\frac{dy}{dx} = \frac{1}{sinh(2x) } * cosh(2x) *2

Simplify:
\frac{dy}{dx} = \frac{2cosh(2x)}{sinh(2x) }

Simplify further:
\frac{dy}{dx} = 2 (\frac{cosh(2x)}{sinh(2x)})

Remember that:
{\frac{cosh(x)}{sinh(x)} = coth(x)

So, your final answer is:
\boxed{ \frac{dy}{dx} = 2coth(2x) }

So, your answer is C. Hope I could help you!

-4(2x-3)<br><br> A) 8x+12<br> B) 8x-12<br> C) -8x+12<br> D) -8x-12
Fofino [41]
Step 1: Multiply -4 and 2x. That would be -8x
Step 2: Multiply -4 and -3. That would be 12 because a negative number times a negative number results in a positive number.
Step 3: Put it all together (8x+12)
Answer: C
