Answer:
is outside the circle of radius of centered at .
Step-by-step explanation:
Let and denote the center and the radius of this circle, respectively. Let be a point in the plane.
Let denote the Euclidean distance between point and point .
In other words, if is at while is at , then .
Point would be inside this circle if . (In other words, the distance between and the center of this circle is smaller than the radius of this circle.)
Point would be on this circle if . (In other words, the distance between and the center of this circle is exactly equal to the radius of this circle.)
Point would be outside this circle if . (In other words, the distance between and the center of this circle exceeds the radius of this circle.)
Calculate the actual distance between and :
.
On the other hand, notice that the radius of this circle, , is smaller than . Therefore, point would be outside this circle.
Part A
The exponential model that describes the situation
The formula is
Y (x)=400 (1+0.02/4)^4x
Y (x)=400 (1+0.005)^4x
Y (x)=400 (1.005)^4x
Where x is the number of years
Part B
The value of the account after 5 years
Y (5)=400×(1.005)^(4×5)
Y (5)=441.96
