Answer:
Interest Manny earns after 2 years is $52
Step-by-step explanation:
Amount deposited = $650
Simple annual interest rate = 4%
To find: Interest after 2 years
We know that the formula to calculate the interest amount is
Simple interest (S.I.) =
where,
P is the initial amount deposited
r is the rate of simple interest in percentage
t is the time in years for which interest is to be calculated
Substituting the known values in the formula, we get
S.I =
= 52
Hence the interest Manny earns after 2 years is $52

Answer:
Distance between the points A and B is 15.52 units.
Step-by-step explanation:
It has been given in the question that an airplane flies along a straight line from City A to City B.
Map has been laid out in the (x, y) coordinate plane and the coordinates of these cities are A(20, 14) and B(5, 10).
Distance between two points A'(x, y) and B'(x', y') is represented by the formula,
d =
So we plug in the values of (x, y) and (x', y') in the formula,
d =
d =
d =
d = 15.52
Therefore, distance between the points A and B is 15.52 units.
