How does a bond differ from a stock

Answers

Answer:

The main difference is that stocks are ownership stakes while Bonds are debt.

Step-by-step explanation:

Stocks and bonds represent two different ways for an entity to raise money to expand their operations. Stocks are simply shares of individual companies but when an entity issues a bond, it is actually issuing debt with the agreement to pay interest for the use of the money. A stock makes you an owner of a business while a bond is just a loan to a business or a person.

What are all the roots of x2-4x+29=0

Answers

To solve a quadratic equation in the form ax^2+bx+c=0 you can use the quadratic formula:

x_(1,2) = (-b\pm√(b^2-4ac))/(2a)

In your case, the equation x^2-4x+29=0 is identified by the coefficient choice a=1,\ b=-4,\ c=29, so the solving formula becomes

x_(1,2) = (4\pm√(16-116))/(2) = (4\pm√(-100))/(2)

As you can see, we have a negative number under a square root, an operation impossible to perform using real numbers. So, this equation has no real solutions.

Two angles are supplementary. The measure of the first angle is 10 degrees more than three times the second angle. Find the measure of each angle

Answers

Answer:

137.5° and 42.5°

Step-by-step explanation:

supplementary angles are two angles whose sum is equal to 180°.

Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.

we know that the sum of first and second angles is 180° (supplementary angles)

so, (3(x)+10°)+(x) = 180°

                   4(x) = 170°

                       x = 170°/4 = 42.5°

so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°

therefore, the angles are 137.5° and 42.5°.
