3/10 = .3 and 87/100 = .87
382.3 - 191.87= 190.43
so the answer is 190.43
Hope this helped!! :))
Looks like you just evaluated the summand for the given value of
, whereas the question is asking you to find the value of the sum for the first
terms.
Let
. Then
is the
th partial sum.
happens to be the first term in the series, which is why that box is marked correct:
But the next partial sum is not correct:
and this is not the same notion as the second term (which indeed is 0.75) in the series.
Anything except pi is a rational number. So 9 and 7/10 is one or it could be a whole number
Answer:
74 degrees
Step-by-step explanation:
The arc degree measurement of the arc that is colored in orange is given as 254 degrees.
The remaining part is the part in green.
The green part plus the orange part should equal 360 degrees because that would make a full rotation around the circle.
.
The green arc has measurement 106 degrees.
We can find x by computing half the difference of the arcs there.
That is,
<span>let n+2=u
so, the equation became= [2/u]-[3/u]=5
=> [(2+3)/u]=5
=> 5/u=5
=> u=5/5=1
thus, u=1
we know u=n+2
so, n+2=1
=> n=1-2=-1
so, n=-1</span>
