Answer:
B.
Mn = Mn-1 + 125 for n > 1 ; M1 = 3,875
Step-by-step explanation:
Since they tell us after 1970, the first data would be that of 1971 and also that if we started since 1970, we do not know the data of 1969, therefore answer B is correct.
Replacing:
Let M1 = 1971 then Mn-1, that is M0 = 1970, we know that the population of 1970 the population is 3750, because it would be 125 less than the subsequent year, and in 1975 there are 3875. Therefore:
in n = 1
M1 = M0 + 125
3875 = 3750 + 125
this gives an equality, thus fulfilling the equation.
Could it be like 1/8 of 100?
In order to find this you need to assume that they are declared as X and as X + 2. This makes the formula for calculating it x (x+2)=483, and this, based on the formulas for calculation, equals
x^2+2x-83=0
From this we can see that a negative X is -23, which when +2 is added results in -21.
The amount you should put is 3846
<h3>How to determine the principal amount?</h3>
The given parameters are:
Amount, A = 4000
Rate, r = 8%
Time = 0.5 year i.e. 6 months
The amount on simple interest is calculated as:
A = P(1 + RT)
This gives
4000 = P * (1 + 8% * 0.5)
Evaluate the product
4000 = P * (1 + 0.04)
Evaluate the sum
4000 = P * (1.04)
Divide both sides by 1.04
P= 3846
Hence, the amount you should put is 3846

Answer:
a) 
= 8 in
b) When the length of AC = 
in. and BC = 
in. = 10 in
c) When the length of AB = 10.2 in. and BC = 3.7 in. 
= 6.5 in
d) When the length of AB = 
in. and BC = 
in. in. 
= 
in
Step-by-step explanation:
a) When the length of AC = 5 in. and CB = 3 in. we have;
The length of 
= AC + CB (segment addition postulate)
Therefore;
= 5 in. + 3 in. = 8 in.
b) When the length of AC = in. and BC = in. we have;
The length of = AC + CB (segment addition postulate)
Therefore;
= in.+ in. = 10 in.
c) When the length of AB = 10.2 in. and BC = 3.7 in. we have;
The length of = AB - BC (converse of the segment addition postulate)
Therefore;
= 10.2 in.+ 3.7 in. = 6.5 in.
d) When the length of AB = in. and BC = in. in. we have;
The length of = AB - AC (converse of the segment addition postulate)
Therefore;
= in. - in.= in.
