13/21

Step-by-step explanation:

8/21 + 7/21 -2/21 = 13/21

X to the power of 3 - 7x + 6 factorise please whole step by step​
Over [174]

Answer:

(x     +  3)(x   -  2)(x - 1)

Step-by-step explanation:

{x}^{3}  - 7x + 6

Factor using Rational Root Theorem.

This means our possible roots are

positve or negative (1,2,3,6). If we try positve 1, it is indeed a root.

This means that

(x - 1)

is a root.

We can divide the top equation by the root (x-1). Our new equation is

( {x}^{2}   +  x - 6)

Now we can factor this completely

(x + 3)(x - 2)

So this equation in factored form is

(x  + 3)(x - 2)(x - 1)

What is the semiannual interest payments of a 30 year bond with a face value of $50 million and a stated annual interest rate of
Snowcat [4.5K]

Based on the stated annual interest rate and the face value of the bond, the semiannual payments will be $1,000,000.

<h3>How can the semiannual interest payment be found?</h3>

The formula to find the semiannual payment is:

= (Face value x Stated annual interest rate) / 2 semi-annual periods per year

Solving gives:

= (50,000,000 x 4%) / 2

= 2,000,000 / 2

= $1,000,000
