I know i use the product rule but I keep getting the wrong answer

dx/dt | (x=3) = 27/2

Explanation:

x*y = 2 (a)

At x = 3, (3)*y = 2 => y = 2/3

Differentiate (a) wrt t,

x.dy/dt + y.dx/dt = 0 (b)

Put x=3, dy/dt=-3 and y=2/3 in the differential equation (b),

3(-3) + (2/3)*dx/dt = 0

dx/dt = (9*3)/2 = 27/2

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
