Step-by-step explanation:
log(z) is defined when z > 0.
For log(9 - x²) to be defined, we have 9 - x² > 0.
=> x² < 9, -3 < x < 3.
The domain of y = log(9 - x²) is (-3,3).
Answer:
Step-by-step explanation:
y-value is 0 and the x value is 5
h = 2
k = -1
Solve for 
(the coefficient of the squared term).
The coefficient of the squared term in the parabola equation is 1/9.
The answer would be 25
9 times 2 is 18 plus 7 is 25
13 inches = 5 feet
----------------------------
Find 1 inch:
----------------------------
1 inch = 5/13 feet
----------------------------
Find 104 inches:
----------------------------
104 inches = 5/13 x 104 feet
104 inches = 40 feet
--------------------------------------------------------
Answer: 40 feet
