Answer:

x^2 -4x-32

Step-by-step explanation:

f(x) = x^2– 5x– 36

g(x) = x + 4

(f +g)(x) = x^2– 5x– 36  +  x + 4

Combine like terms

            = x^2 -4x-32

Answer:

\longmapsto \: f(x) =  {x}^{2}  - 5x - 36 \\  \longmapsto \: g(x) = x + 4 \\  \longmapsto(f + g)(x) \\  = f(x) + g(x) \\  = ( {x}^{2}  - 5x - 36) + (x + 4) \\  =  {x}^{2}  - 5x - 36 + x + 4 \\  = \boxed{  {x}^{2}  - 4x - 32}

  • <u>x²-4x-32 (in standard form)</u> is the right answer.

Let f(y) = y^4 - 3y^3 + y - 3 and g(y) = y^3 + 7y^2 - 2. Find f(y) + g(y). Write your answer as a polynomial with terms of decre
Anarel [89]
<h3>Answer:   y^4 - 2y^3 + 7y^2 + y - 5</h3>

Work Shown:

h(y) = f(y) + g(y)

h(y) = (y^4 - 3y^3 + y - 3) + (y^3 + 7y^2 - 2)  

h(y) = y^4 - 3y^3 + y - 3 + y^3 + 7y^2 - 2  

h(y) = y^4 + (-3y^3+y^3) + 7y^2 + y + (-3 - 2)

h(y) = y^4 - 2y^3 + 7y^2 + y - 5

This is a fourth degree polynomial (aka quartic).

On May 1, you sign a $1000 note with simple interest of 8.5% and a maturity date of December 19. You make partial
Lelu [443]

Answer:

The amount to be repaid is $379.26.

Step-by-step explanation:

Period of note from May 1 to December 19 = 233 days

Amount of note or principal = $1,000

Simple interest rate = 8.5%

Maturity date = December 19

Repayments:

June 2 = $475

Nov. 4 =  $200

Total paid $675

Simple interest = $54.26 ($1,000 * 8.5% * 233/365)

Total amount to be repaid = $1,054.26

Total amount repaid =               675.00

Balance to be paid on maturity $379.26
