1 answer:
The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486
<h3>Compound interest</h3>
Compound interest is given by:
where t is the period, r is the rate, P is the initial amount, A is the final amount and n is the times compounded.
Given P = 2950, r = 0.084, n = 4, t = 2, hence:
The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486

Answer:
a) The coordinates of the missing vertex = (7, 8)
b) Area = 18 square units
Perimeter = 18 units
Step-by-step explanation:
a) We know three of the four vertices:
A: (4, 2) C ______ D(?)
B: (7, 2) | |
C: (4, 8) A |______| B
To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:
Hence, the distance of point D from point C in the x-direction is:
Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:
Then, the distance of point D from point B in the y-direction is:
Therefore, the coordinates of the missing vertex (point D) are:
b) The area of the rectangle is:
The perimeter is given by:
