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
Answer:
2.5 km left
The midpoint is half of 5, which is 2.5, so he'll still have 2.5 km left to complete
Answer:

Step-by-step explanation:
Given
Represent the coordinates of circle A with (x,y)
<u>Translation</u>
Left = 3 units
Up = 4 units
Required
Determine the coordinates of B
When a point (x,y) is translated by h units left, the new point is: (x - h, y)
When a point (x,y) is translated by b units up, the new point is: (x, y + b)
So, when circle A is completely translated to B, the new points of B is:

In this case:

So:
