I'm guessing the second derivative is for <em>y</em> with respect to <em>x</em>, i.e.

Compute the first derivative. By the chain rule,

We have


and so

Now compute the second derivative. Notice that
is a function of
; so denote it by
. Then

By the chain rule,

We have

and so the second derivative is

Answer:

Step-by-step explanation:
This is the correct answer, because ever since the transit system was made, car rides went down and down.
Answer:
6
Step-by-step explanation:
24/4=6
Number of outcomes when flipping a coin = 2
Favorable outcome is landing on head.
So,number of favorable outcomes = 1
Probability of getting a head when flipping a coin =

Number of outcomes when rolling a dice = 6
Favorable outcomes are rolling 4,5 or 6.
So,number of favorable outcomes = 3
Probability of getting 4 or a bigger number when rolling a dice =

Thus the probability of getting a head when flipping a coin and getting a number equal to or greater than 4 when a dice is rolled =
So, option A gives the correct answer
The answer is 12%
Here’s how:
4.44 divided by 37 equals .12
1.8 divided by 15 equals .12
3.12 divided by 26 equals .12
3.60 divided by 30 equals .12
2.16 divided by 18 equals .12
