Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:
Square both sides to get rid of the square root:
Now plug the known value of the speed to find the distance:
So the closest answer is the last one: d=0.155km
Answer:
m=-44
Explanation: distribute the negative and add -1/4 to m and then take the 5 away from 16 and then multiply both sides
I the answer is C I’m not really sure but I’ll update u when i get the answer
