Step-by-step explanation:
a) 1.16× 10^-6
standard form should be less than 10. therefore, count decimal places from where the decimal point is located to the right until you reach a number less than 10 ....count the number of shifts in the above is 6 shifts to the right. when moving to the right, power will be negative.(-6)
1.157/1.16 ×10^-6
b) 6.79 × 10^10
67890000000....count till a number less than 10.there will be 10 shifts to the left. the 10 will be your power,(positive) since u r moving to the left exponent is positive
6.789/6.79 × 10^10
Step-by-step explanation:
SAS is Side - Angle (between the sides) - Side
BC and CD are shown to be congruent with the markers that cross the line segments.
AC and AC are the same because they are the same.
The only things needed are the congruent angles between the sides.
The angles are ACD and ACB, because those are the angles between AC and BC and AC and CD.
I think the best answer would be (A) (2.1+5.9+3.7) but the only difference is that one is negative an the other is positive

Answer:
The population in 2017 is 171 million
Step-by-step explanation:
Let's assume population starts from 1991
so,
initial population is 147 million
so, 
we can use formula
we can plug A=147
In 1998:
t=1998-1991=7
now, we can plug these values into formula and find k
Divide both sides by 147
now, we can plug it back
and we get
In 2017:
t=2017-1991=26
we can plug it and find P
So,
The population in 2017 is 171 million
