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
Toppings = nCr
This gives
Toppings = 4C2
Evaluate the combination expression
Toppings = 6
Hence, Ross have 6 different topping combination to select from

Answer:
continuous
Step-by-step explanation:
Since the function d=45t can have numbers in between and time is constantly happening, he does not hop, or skip at 1 second, then 5 seconds...he is continuously traveling, so time = 1 sec, 1.1 sec., 1.1000001, 1.000002, etc. time does not stop therefore if you graphed this, you would connect the dots, therefore, it is continuous

Answer:
1 solution
Step-by-step explanation:
s² - 35 = -35
Add 35 to both sides: <em>s² = 0</em>
<em>s can only be 0, and 0 has no positives nor negatives</em>, so one number.
