Answer:
c. quarterly
Step-by-step explanation:
To start with 1 year is equal to twelve months
3months out of 12 months will be;
3/12= 1/4
Here it is compounded quarterly and n=4 where n is the number of compoundings a year.
Lets study the compound interest formula;

where;
A=The ending amount
P=Starting amount
r=rate of interest expressed as a decimal
n=number of compoundings a year
t=total number of years
The number of compoundings in any one year can be an interest compounded yearly where n=1, semi-annually with n=2, quarterly where n=4, monthly where n=12, weekly and n=52 and finaly daily with n=365.
Answer:
The value is 78
Step-by-step explanation:
We need to add them all together
6+15+24+33
78
Answer:
Step-by-step explanation:
note :
( a + b )^3 = a^3 +b^3 +3 a²b +3b²a + b^3...(*)
the condition is : r = 1 and p=1
put : x= a and b = 1 in (*) you have :
(x + 1)^3 = x^3 +3x² +3x +1
the zeros is : x = - 1
bcause : x^3 +3x² +3x +1 = 0 .... (x + 1)^3 = 0 so : x = - 1
Answer:
Step-by-step explanation:
In triangle ADC,
b+50+60=180(sum of angles of triangle equals 180)
or,b=180-110
▪b=70
also,
In triangle ABD,
angleA = 30+50=80
now,
a+80+60=180(sum of angles of traingle equals 180)
or,a=180-140
▪a=40'
Ans.
