Hi. I need help with these questions (see image)
Please show workings.

A:

B:

c: 2x

Step-by-step explanation:

To find the derivative of x raised to the nth power we use the following template

Something else to keep in mind is that

So knowing this we can rewrite a as follows

so we can use the template above and get

So that simplifies to

B: Same kind of deal here

C: this one is by far the easiest because the derivative of a constant is 0 so we can just apply the same template from before and get

2x

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
