Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 4x - 32
g(x) = x - 4
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute: (f + g)(x) = x² + 4x - 32 + (x - 4)
- Combine like terms (x): (f + g)(x) = x² + 5x - 32 - 4
- Combine like terms (Z): (f + g)(x) = x² + 5x - 36
Answer:
A = 7 1/9 m^2
Step-by-step explanation:
The area of a square is the side length squared.
A = s^2
A = (2 2/3) ^2
Change the mixed number to an improper fraction
2 2/3 = (3*2+2) /3 = 8/3
A = (8/3) ^2
= 64/9
Change this back to a mixed number
9 goes into 64 seven times (9*7 = 63 with 1 left over)
7 1/9 m^2
The area is 7 1/9
Answer: see below
<u>Step-by-step explanation:</u>
1) Foci is plural for Focus. Since a hyperbola has two focus points, they are referred to as foci. The foci is where the sum of the distances from any point on the curve to the foci is constant.
2) When determining the equation of a hyperbola you need the following:
a) does the hyperbola open up or to the right?
b) what is the center (h, k) of the hyperbola?
c) What is the slope of the asymptotes of the hyperbola?
3) The equation of a hyperbola is:
- (h, k) is the center of the hyperbola
- ± b/a is the slope of the line of the asymptotes
- The equation starts with the "x" if it opens to the right and "y" if it opens up
