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).
Answer:
1001
1
Step-by-step explanation:
If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in with discriminant
, the following is true:
Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
