Answer:
is scientific notation of 78 billion
Step-by-step explanation:
For scientific notation , follow the following notation:
-------->(equation 1)
Let,
In standard form
![a = 7.8000000000](https://tex.z-dn.net/?f=a%20%3D%207.8000000000)
or
![a = 7.8](https://tex.z-dn.net/?f=a%20%3D%207.8)
As decimal point move 10 places from right to left, therefore
b = 10
Put the value of 'a' and 'b' in (equation 1)
is scientific notation of 78 billion
Its the 2nd one becuase 2(-1)+2=0 witch is greater than -4.
The absolute difference between the greatest and the least of these three numbers in the arithmetic sequence is 10.
The sequence is an arithmetic sequence. Therefore,
d = common difference
let
a = centre term
Therefore, the 3 consecutive term will be as follows
a - d, a, a + d
a - d + a + a + d = 27
3a = 27
a = 27 / 3
a = 9
Therefore,
(a-d)² + (a)² + (a + d)² = 293
(a²-2ad+d²) + 9² + (a² + 2ad + d²) = 293
(81 - 18d + d²) + 81 + (81 + 18d + d²) = 293
243 + 2d² = 293
2d² = 50
d² = 50 / 2
d = √25
d = 5
common difference = 5
Therefore, the 3 numbers are as follows
9 - 5 , 9, 9 + 5 = 4, 9, 14
The difference between the greatest and the least of these 3 numbers are as follows:
14 - 4 = 10

Answer:
Step-by-step explanation:
Basically you can see it hits -5 as a minimum and that means there is 2 there and then -1 and then hits 4 3 times and then 7
So your answer is x=-5 with multiplicity of 2 x=-1 and x=4 with multiplicity of 3 and x=7 once.
6 times 4 is 24, divided by 2 is 12, minus 1 is 11, plus 5 is 16.
