36, because the square root of 4 is 2 and the square root of 81 is 9. You multiply those and then double it to get 36.

Is 0.26 is closer to 0, 1/2 or, 1
professor190 [17]
Here, we know 1/2 = 0.50
So, the difference between 0.50 & 0.26 is 0.24
And difference between 0 and 0.26 is 0.26
1 is very apart from 0.26 as compared to other two

So, It is closer to 1/2

Hope this helps!

D is the midpoint of CE. If CD= 2x+10 and DE =3x-18, find x and CE<br><br> x=<br> CE=
Veseljchak [2.6K]

Answer:

<h2>x = 28</h2><h2>CE = 132</h2><h2 />

Step-by-step explanation:

|<------------- CE -------------------->|

C-------------------D-------------------E

       2x + 10              3x - 18

2x + 10 = 3x - 18

2x - 3x = -18 - 10

-x = -28

x = 28

CE = 2x + 10 + 3x - 18

CE = 2(28) + 10 + 3(28) - 18

CE = 56 + 10 + 84 - 18

CE = 132

D(n)=6-4(n-1) Find the fifth term in the sequence
LiRa [457]

Answer:

5th term: -10

Step-by-step explanation:

To find the nth term in the sequence, you can substitute n into the equation:

d(n) = 6 - 4(n - 1)

Since we want the 5th term, we substitute 5:

d(5) = 6 - 4(5 - 1)

d(5) = 6 - 4(4)

d(5) = 6 - 16

d(5) = -10
