The number of different topping combination illustrates combination
Ross have 6 different topping combination to select from
<h3>The number of different combination</h3>
The given parameters are:
Extra toppings, n = 4
Toppings to select, r = 2
The number of extra topping that Ross can select is then calculated using the following combination formula

(18-7x)+1= -9 Hope this helps ^^
The values of a and b are 1/4 and 1/5 respectively
<h3>How to determine the true statement?</h3>
The function is given as:
16x^2 - 25y^2 = 1
The above function is a horizontal hyperbola.
A horizontal hyperbola that passes through the origin is represented as:

Rewrite 16x^2 - 25y^2 = 1 as

By comparison, we have:


Solve for a and b


Hence, the values of a and b are 1/4 and 1/5 respectively
