Answer:
f(x) = x^4/12 + 8x + 4
Step-by-step explanation:
f"(x) = x^2
Integrate both sides with respect to x
f'(x) = ∫ x^2 dx
= (x^2+1)/2+1
= (x^3)/3 + C
f(0) = 8
Put X = 0
f'(0) = 0+ C
8 = 0 + C
C= 8
f'(x) = x^3/3 + 8
Integrate f(x) again with respect to x
f(x) = ∫ (x^3 / 3 ) +8 dx
= ∫ x^3 / 3 dx + ∫8dx
= x^(3+1) / 3(3+1) + 8x + D
= x^4/12 + 8x + D
f(0) = 4
Put X = 0
f(0) = 0 + 0 + D
4 = D
Therefore
f(x) = x^4 /12 + 8x + 4
This means 35% used buses. 3+4=7, so 20% took school buses while 15% took public buses. 65%-35%=30% who mean the difference, so 30% is 360. You ask what is 15% -- that's half of that difference, or 180.
Answer:
The correct answer is 20%

Answer:
n<2
Step-by-step explanation:
6.2n<2n+8.4
Move variable to the left hand side and change its sign
6.2n - 2n < 8.4
Combine like terms
4.2n < 8.4
divide both side by 4.2
n < 2
