Answer:
From the calculation for both the accounts, it is clear that both the account double in the same time period of 14 years 26 days .
Step-by-step explanation:
Given as :
The principal for the first account = p = $100
The rate of interest = r = 5% compounded annually
The account gets double , so, Amount = A = $200
Let the time after which account gets double = t years
So<u>, From Compound Interest method</u>
Amount = Principal ×
As amount is double its principal
So, A = 2 × $100 = $200
Or, A = p ×
Or, $200 = $100 ×
Or, =
Or, 2 =
Taking Log both side
=
Or, 0.3010 = t
Or, 0.3010 = t × 0.0211
∴ t =
I.e t = 14.26
So, The time period to get account double is 14 years 26 days
<u>Again </u>
Amount = Principal ×
Or, A = p ×
As amount is double its principal
So, A = 2 × $1000 = $2000
Or, $2000 = $1000 ×
Or, =
Or, 2 =
Taking Log both side
=
Or, 0.3010 = t
Or, 0.3010 = t × 0.0211
∴ t =
I.e t = 14.26
So, The time period to get account double is 14 years 26 days
Hence From the calculation for both the accounts, it is clear that both the account double in the same time period of 14 years 26 days . Answer
Answer:
n = 28°
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended on the same arc.
Also angles subtended on the same arc are congruent , thus
m = n
Then
35 + m = (98 + n ) ← multiply both sides by 2 to clear the fraction
70 + 2m = 98 + n , but since m = n, then
70 + 2m = 98 + m ( subtract m from both sides )
70 + m = 98 ( subtract 70 from both sides )
m = 14 and n = 28
