An alternating current. I Amperes, is given by i = 10sin2nft. where f is the frequenct in Hertz and t the time in seconds. What is the rate of change of current when t = 20ms given that f = 150 Hzπ​

answer: t=3

step-by-step explanation:

answer: idk

step-by-step explanation:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

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.
