Answer:
A
Step-by-step explanation:
Given
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take the square root of both sides )
x = ±
= ± 5
Solutions are x = 5 and x = - 5
Answer:
-15.9%
Step-by-step explanation:
Opening stock = $8.18
Closing stock = $6.88

It would seem that r correlates to line AC. So another name could be Line AC. Remember to put a line above the two letters to let people know it is a line. I hope this helps! =)
Answer:
1) The value of c is given by

2) The value of k is given by

Step-by-step explanation:
Given that function g is defined by
, where c is a constant.
To find c:
Also given that value of g(x) at x=0.5 is equal to -1
ie., 
At x=0.5






Therefore 
2) Given that function h is defined by
, where k is a constant.
To find k:
Also given that value of h(x) at x=20 is equal to 65
ie., 
At x=20



Therefore
