Answer:
Step-by-step explanation:
The initial amount invested is P0
Say it is compounded periodically either quarterly or monthly or semi annually with interest r%
If for a period interest is r%
Then after first period principal = principal+simple interest
=
where n is the no of times in a year it is compounded. n = 4 if quarterly, 12 if annually, etc
At the end of II period we have
Principal =
So for interest again the process is repeated
Thus we repeat this nt times which result in power with nt
Hence the formula
Answer:
12. n = 8
13. t = 308
14. k = 5
Step-by-step explanation:
12. 2/3 = n/12
Multiply by 4 because 3×4 = 12
So, n = 8
13. 33/t = 3/28
Multiply by 11 because 3×11 = 33
So, t = 308
14. k/6 = 15/18
Multiply by 3 because 6×3 = 18
So, 3k = 15. k = 5

Answer:
The two triangles are congruent, so any point on CD will be equidistant from endpoints of AB.
Step-by-step explanation:
Let the consider the figure as per the attached image:
AB be a line whose perpendicular bisector line is CD.
CD divides the line AB in two equal line segments making an angle of 
on both the sides as shown in the attached figure.
Let a point on CD be E.
Here, two triangles are formed:
Side ED is common between the two triangles.
Also, Side ED is perpendicular bisector:
And Sides AD = DB
According to SAS congruence (i.e. Two sides are equal and angle between them is equal):
And as per the <em>properties of congruent triangles, all the sides are equal.</em>
EA and EB is the distance of point E on line CD from the endpoints of line AB.
Hence proved that Any point on CD is equidistant from the endpoints of AB .
