Answer:
The correct answer is -7.5 years.
Step-by-step explanation:
Given:
Principle amount = 12000
Interest = 4320
time = ?
rate = 4.8 simple interest
Solution:
We know that simple Interest I = (P*t*r)/100
then t = I*100/p*r
putting values in formula:
t = 4320*100/4.8*12000
= 432000/57,600
= 7.5 years
The sign in the exponent: positive->increases, negative->decreases. Think that a negative sign implies 1/exponential and you'll clearly see the reason.
To find the area of each triangle, you just have to multiply the base(bottom) times the height and then divide your answer by 2. Works for all triangles.
1/3x4x4x8xpi=128/3pi
