You replace x with (a+1)
Then f(a+1) = (a+1)^2+1
= a^2+2a+1+1
= a^2+2a+2

Step-by-step explanation:
Step-by-step explanation:
1 heure = 60 minutes.
60 minutes = 1 heure
1 minute = 1/60
i) 12 minutes = 1/60 × 12
= 12/ 60
= 1/5
ii) 35 minutes = 1/60 × 32
= 32/ 60
= 8/ 15
iii) 40 minutes = 1/60 × 40
= 2/3
iv) 45 minutes = 1/60 × 45
= 3/4
v) 50 minutes = 1/60 × 50
= 5/6
vi) 52 minutes = 1/60 × 52
= 13/15
vii) 58 minutes = 1/60 × 58
= 29/ 30
ainsi, c'est mieux d'utiliser la formule:
x min = x/60 hr
j'espère que cela vous aide,
bonne journée!

Answer:
120
Step-by-step explanation:
The function C(n, k) can be written in terms of factorials:
C(n, k) = n!/(k!(n -k)!)
Then ...
C(16, 2) = 16!//(2!(16 -2)!) = (16·15)/(2·1)
C(16, 2) = 120
