Answer:
the anwser should be 45 try asking your teacher
Step-by-step explanation:
(50+40)/2 = 45
bisect = to cut into two equal halves.
so from that theorem Juan used we can derive that once both diagonals bisect each other, the halves of AO = OC and DO = OB.
Answer:
3x^2-4x+8 (R -1)
Step-by-step explanation:
We can use synthetic division:
-2 | 3 2 0 15
<u>____-6 8 -16</u>
3 -4 8 | -1
So basically, you solve x+2=0 (which is x=-2) and then you put it on the left side. Then make a line and put the coefficients of the polynomial you want to divide. Then with the first coefficient it gets dropped. You would then multiply this by -2 (so 3*-2=-6) and then combine it with 2 in the second column (2+-6=-4). Then we do the same thing with the third column (-4*-2=8) and combine (0+8=8). Same with the fourth column (8*-2=-16) but when we combine this time the answer will be our remainder (15+-16=-1).
So how you would read your final answer is 3x^2-4x+8 (R -1) which the numbers you get are the coefficients.
If you are looking for √16, you are looking for the square root of 16. The square root of a number is defined by what number multiplied by itself will get you.
x^2 (a number squared) = 16.
√16 = x.
Let's try from numbers 1-5 for a square.
1x1 = 1
2x2 = 4
3x3 = 9
4x4 = 16
√16 = 4.
I hope this helps!
Answer:
1/3
Step-by-step explanation:
p(A) = (number of A's on the spinner)/(total number of letters on the spinner)
p(A) = 2/6 = 1/3
