How much money should be invested in an account that earns 8% interest compounded quarterly to yield $10,000 in 4 years? (Round
sweet [91]

Answer:

757,576cents

Step-by-step explanation:

Given

Amount = $10000

Time = 4years

Rate = 8%

n = 1/4 year (compounded quarterly

Using the formula to get the principal

A = P(1+r/n)^nt

10000 = P(1+0.08/0.25)^4(1/4)

10000 = P(1+0.32)

10000= 1.32P

P = 10000/1.32

P = 7575.76

Hence he suppose to invest $7575.76 which is equivalent to 7575.76×100 cents i.e 757,576cents

Tasya [4]

The correct option is D for the placement of regular polygon and the rhombus.

  • A polygon is a two-dimensional enclosed image created by connecting three or more straight lines.
  • A rhombus is a special parallelogram because it meets the definition of a parallelogram, which is a quadrilateral to two pairs of parallel sides.
  • A polygon is made up of three parts:
  1. Sides: A side is a line segment that connects two vertices.
  2. Vertices: A vertex is the point where two sides meet.
  3. Interior and exterior angles An interior angle is an angle formed by joining the sides of a polygon within its enclosed surface.

As, all the given figures comes under the regular polygon, all are placed in the left circle.

But the three diagram in white, orange and blue colour are regular polygon along with rhombus.

Thus, all three are placed in the intersection of the both circle of the vein diagram.
