Answer:
Brailniest
Step-by-step explanation:
0.25k+1.5-k-3.5
-0.75k-2
so you are right
Answer:
1134
Step-by-step explanation:
Formula for diameter=2 x r
(π is 3.14)
Formula for area= π x r^2
So all you basically have to do is go backwords with the first one then plug the radius into the second one normally
38/2=19
Now just plug it into your second equation
π x 19^2=1134.11494795
And lastly round that to 1134, easy! :)
The exponential function equivalent to 4=ln x will be evaluated as follows:
from
4=ln x
introducing the exponential function
e^4=e^(lnx)
but
e^(lnx)=x
thus
e^4=x
answer:
e^4=x
The point on the unit circle corresponding to -180 degrees is
((x, y) = (-1, 0).
<span>tan(-180°) = y/x = 0/(-1) = 0</span>
