Answer:
It's exponential growth.
Step-by-step explanation:
b/c any value of b that's greater than 1 is an exponential growth function, and anything that's 0<b<1 or if b<0, the function would be an exponential decay.
Answer:
nCr = n! / (r!)(n-r!).
Step-by-step explanation:
That would be nCr = n! / (r!)(n-r!).
A quick way of working these out is as follows:
Take 7C4:
this is 7*6*5*4/4*3*2*1 Cancelling out the 4 and 3*2:
= 7*5
= 35.
15C12 = 15C(15-12)
= 15C3
= 15*14*13 / 3*2*1
= 5*7*13
= 455.
Answer:
Step-by-step explanation:
95 ÷ 6 = <em>x</em>
<em>x </em>=
1. (x, y) = (7, -12)
2. x = 1, x = 2 are both solutions
