Question is nottttt clearrrrrrr
Answer:
T < - 4
Step-by-step explanation:
This kind of exercise can be real drudgery. But it's almost all simple arithmetic, so better you than me. I'll do one of these for you, which will show you how to do the other one.
a). sin · cot / sec
You're supposed to know that [ cotangent = cosine/sine ]
and [ secant = 1/cosine ].
Then the problem becomes
sin · (cos/sin) / (1/cos) = cos²
Aw shucks, I might as well also set up 'b)' for you:
b). cos · csc / tan
You're supposed to know that [ cosecant = 1/sine ]
and [ tangent = sine/cosine ].
Then the problem becomes
cos · (1/sin) / (sin/cos) = (cos/sin)²
Now simply plug in the given values of cos A and sin A .
And may I compliment you on your nail care !
Answer:
1.25 hours
Step-by-step explanation:
If you're going 60 miles per hour, that's exactly how much miles you travel in an hour if that is your constant speed you are going the entire time, so it is at least 1 hour and we know it's not 4500 hours and it cant be .8 hours or 135 hours, think of yourself going on a caride would it really take 135 hours ? No so its 1.25. Also multiply 60 by 1.25 and you get 75.
1. You don't get the full "learning Process".
2. They are not <em><u>always </u></em>the best way/
These are my reasons hope they help! :D
