Give the required elements of the hyperbola. 4x^2 - y^2= 16 the value of b is:

a = 2  

b = 4

Step-by-step explanation:

4x² - y² = 16  

General equation for a horizontal hyperbola:  

(x-h)²/a² - (y-k)²/b² = 1  

with center (h,k)  & vertices (h±a,k)  

Divide by the constant  

4x²/16 - y²/16 = 1  

x²/4 - y²/16 = 1  

x²/2² - y²/4² = 1  

center (h,k) = (0,0)  

a = 2  

b = 4

step-by-step explanation:

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
