How Can Cassie probe the quadrilateral ABCD is a parallelogram

Mathematics
1 answer:
Mashcka [7]3 years ago
7 0

Answer:

Explained below.

Step-by-step explanation:

A quadrilateral with two opposite pair of sides parallel to each other is known as a parallelogram.

To prove that a quadrilateral is a parallelogram, the following properties can be used:

  • The two pair of opposite sides are same in length, i.e. AB = CD and AD = BC.
  • The two pair of opposite angles are congruent, i.e. ∠A ≅ ∠C and ∠B ≅ ∠D.
  • The two pair of consecutive angles are supplementary, i.e. ∠A + ∠B = 180° and ∠B + ∠D = 180°.
  • The diagonals of the quadrilateral bisect each other. i.e. AE = EC and BE = ED.

If the quadrilateral ABCD satisfies these properties then it can be proved that the quadrilateral ABCD is a parallelogram.

Suppose you invest $16000 at 9% interest and that it is compounded daily. How much will you have in 8 years?
kramer

Answer:

The amount after 8 years is $ 16,031.579

Step-by-step explanation:

Given as :

The Principal invested = $ 16000

The rate of interest compounded daily = 9 %

The time period = 8 years

Let The amount after 8 years = $ A

<u>From Compounded method </u>

Amount = Principal invested × (1+\dfrac{\textrm Rate}{365\times 100})^{365\times \textrm Time}

Or, Amount = 16000 × (1+\dfrac{\textrm 9}{365\times 100})^{365\times \textrm 8}

Or, Amount = 16000 × (1.0002465)^{8}

∴  Amount = $ 16,031.579

Hence The amount after 8 years is $ 16,031.579   Answer
