4 0

Answer:

The answer is D.) 6/8 and 3/4

Step-by-step explanation:

If you count how many lines there are you get 8 lines so we know the denominator has to be eight and since the point is on the 6th line the first one is 6/8 and since you can simplify it you get 3/4 which gives you D.)

Hope I helped

Find the derivative of Y=2xcos2x​
Nastasia [14]

Answer:

Y' = -xsin(2x) + 2cos(2x)

Step-by-step explanation:

For this problem, we will need to use the product rule since you have two terms that contain the variable x.

The product rule is simply as follows:

The derivative of the function is the product of the first term times the derivative of the second term plus the derivative of the first term times the second term.

Note the derivative of 2x with respect to x, is 2.

Note the derivative of cos(2x) with respect to x is (-1/2) sin(2x).

With this in mind, let's find the derivative of our function with respect to x.

Y = 2xcos2x

Y = 2x * cos(2x)

Y' = 2x * (-1/2)sin(2x) + 2 * cos(2x)

Y' = (2x * -1 / 2) sin(2x) + 2 * cos(2x)

Y' = (-x)sin(2x) + 2cos(2x)

So the derivative of our function is Y' = -xsin(2x) + 2cos(2x) according to the application of the product rule.

Cheers.

Rolex buys computer disks at a price of 4 for $5 and sells them at a price of 3 for $5. How many computer disks must he sell to
Lina20 [59]

Given that Rolex buys computer disks at a price of 4 for $5 .

That means cost price of 1 disk = 5/4


Given that Rolex sells them at a price of 3 for $5.

That means selling price of 1 disk = 5/3


Profit on 1 disk = selling price - cost price

Profit on 1 disk = \frac{5}{3}-\frac{5}{4}

Profit on 1 disk = \frac{5}{3}\cdot\frac{4}{4}-\frac{5}{4}\cdot\frac{3}{3}

Profit on 1 disk = \frac{20}{12}-\frac{15}{12}

Profit on 1 disk = \frac{5}{12}

Now we have to find how many disk to be sold to get the profit $100

so we just divide $100 by profit on 1 disk

\frac{100}{\left(\frac{5}{12}\right)} = 100\cdot\frac{12}{5} = 240

Hence final answer is 240 disks.
