This is a question on my Trig HW that I can not figure out how to solve.
We need at least 9 more requests to produce the answer.
1 / 10 have requested this problem solution
The more requests, the faster the answer.
If secx<0 and cotx>0 is sinx positive or negative? And what quadrant is the terminal side of x in?
How do you solve this trig function.
I am using Haversines formula to find the distance between two
longitude/latitude coordinates and do not understand this part of
the formula. I have asked this question before but the answer did
not help me at all it just restated the formula. My specific
question has to do with the comma. How do I solve for c.
For example, if a = 0.2, how would I find c. Thanks.
c= atan2(Vā, VI-a)
When establishing PYTHONPATH, which terminal window to use? Just the regular terminal window (.bash) that opens when I click on Terminal in Utilities in Applications? Also, as I add the following line to the end: export PYTHONPATH="/Users/my_user/code", do I add it to this line, which is already there for some reason? : my-MacBook-Air:~ myname$ Also, how do I save this file in Mac? And finally, what do i substitute this by?: /Users/my_user/code. Is this the path where I installed Python?...
Can you use my new numbers in the problem below to solve my
problem? I know the textbook solution is -4, but I cant figure out
how to plug in 3.95. Thanks!
In Figure 21-23, three charged particles lie on an xaxis.Particles 1 and 2 are fixed in place. Particle 3 is free to move,but the net electrostatic force on it from particles 1 and 2happens to be zero. If L23 =42, what is the ratiog/92? 112 Fig. 21-23
In a cell, the Keq for a reaction is 500. Is this a spontaneous reaction in the cell? Okay. At first I thought it had an obvious answer because I was thinking that since Keq >> 1, deltaG would be large and negative. Then I looked at my book and saw that only deltaG0 is related to Keq through the equation deltaG0 = -RT ln Keq. Since this question is asking about if the reaction is spontaneous inside the cell...
find the center and radius of the circle with the given equation: x^2 + y^2 - 12x + 2y + 21 = 0 Please show detailed step-by-step directions so I can figure out how to do this on my own, Thank you!
I can't figure out how to solve this homework problem from my
Intro to Python 2 class. Could someone please show me the correct
code? Will rate very highly.
I need help figuring out how to approach a problem. I need to determine the initial velocity of an object for it to be at a specific height at a specific time. For example, what would the initial velocity of an object need to be for it to be at 38.7m @ 4.7 seconds if thrown straight up from the ground (launched up at 90 degrees)? If I understand correctly, there could be two answers, one for the initial trip...
I can not seem to figure out the answer to this question. I have posted a photo of the problem statement with some of my work below.
What is a resting potential? Is it positive or negative? The resting potential is mainly due to the main _____-charged large molecules stuck inside the neuron. The Na+/K+ pump pushes Na+ _____ of the cell and K+ ____ of the cell (in or out for each ion) Where is K+ concentrated, inside or outside of the neuron? Where is Na+ concentrated, inside or outside of the neuron? The action potential starts with an rise in membrane voltage. This is due...
