1-7
2-8000
3-400
Are the correct answers
You check both of them:
1. 3*3-(-8)/4=9-(-2)=9+2=11 it's true
2. 3*4-4/4=12-1=11 true
so both of them are solutions
Answer:
Step-by-step explanation:
5+1+3/8= 9/8
9/8= 1 1/8
Answer: 17 years
Step-by-step explanation:
Exponential equation for compund amount( compunded continuously):
, where P= Principal value , r= rate of interest , t= time.
Given: A= 2P
r =4%= 0.04
To find : t
Substitute all values in the formula , we get
Taking natural log on both sides
hence, it will take 17 years (approx).
