Answer:
D
Step-by-step explanation:
4x2=8
5x2=10
6x2=12
This answer is the closest to 12 but it doesn't go over 12, so this is less than or equal to 12
It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).
So, use "arctan x" instead.
Then the problem becomes: "differentiate cos (arctan x)."
You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:
(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]
Answer:
430 minutes or 7 hours and 10 minutes
Step-by-step explanation:
From 8:35 am to 9 am is 25 minutes. There are 60 minutes in an hour and 9 am to 3 pm is 6 hours. 3:00 to 3:45 pm is an additional 45 minutes.
60 minutes x 6 hours = 360 minutes
360 + 25 + 45 = 430 minutes
6+(4/5)
=(30/5)+(4/5)
=34/5
