F(x)=x^2-3x+1/2, if f(4)
Substitute x with 4, to get
f(x)=x^2-3x+1/2
f(4)=4^2-3(4)+1/2
f(4)=16-12+1/2
f(4)=4+1/2
f(4)=4 1/2 or 4.5. Hope it help!

Answer:
- recursive: a[1] = 7440; a[n+1] = a[n] -120
- explicit: a[n] = 7440 -120(n -1)
Step-by-step explanation:
The sequence of amounts in Jackson's account will be ...
7440, 7320, 7200, ...
with a first value (a1) of 7440 and a common difference (d) of -120.
The recursive formula for an arithmetic sequence is ...
a[1] = a1
a[n+1] = a[n] +d
For our sequence, the recursive formula is ...
a[1] = 7440
a[n+1] = a[n] -120
__
The explicit formula for an arithmetic sequence is ...
an = a1 +d(n -1)
For our sequence, the explicit formula is ...
a[n] = 7440 -120(n -1)
Answer:
1/6 (=0.1667)
Step-by-step explanation:
If we look just at weeks 2, 3 and 4:
Week 2: 40 regular + 6 overtime
Week 3: 40 regular + 10 overtime
Week 4: 40 regular + 4 overtime
Total number of regular hours = 40 + 40 + 40 = 120
Total number of overtime hours = 6 + 10 + 4 = 20
number of overtime hours as a fraction of number of regular hours
= number of overtime hours / number of regular hours
= 20 / 120 (simplify by dividing numerator and denominator by 20)
= 1/6 (=0.1667)
