Its like a polynomial.
cosx=x
so it'll be like
2x^2+3x-2=0
<span>(2x−1)(x+2)
</span>
which makes your life easy because you do not have to solve cos(x)=−2 because it cannot be, so only solve cos(x)=1/2
-5.5 i think if i’m wrong sorry but good luck :)
Answer:
[2], [5], [8],
Step-by-step explanation:
Answer:
11 with 3 left over
Step-by-step explanation:
4 x 20 = 80
80 / 7 = 11 with remainder of 3
Find the volume
volume=hpir^2
d/2=r=16/2=8
1.
hmm, ok, after 1/2 hour or 30 mins
30/5=6
6*1=6, 6 cubic meters
volume=6, solve for height
v=hpir^2
but r=8 all the time, solve for h
6=hpi8^2
6=hpi64
6/(64pi)=h
the depth is

meters or about 0.02984155182973037545666570563235 meters
the depth is about 0.03 meters
2. the full volume is
v=6pi8^2=6pi64=384pi
1 cubic meter every 5 mins so
384pi/1 is how many 5 mininute intervals
so 384pi times 5=total minutes=1920pi minutes or about 6031.8578948924030178482752958966minutes
