F''(x) = 6x + 8
∫f''(x) = f'(x) = 3x^2 + 8x + c1
∫f'(x) = f(x) = x^3 + 4x^2 + c1x + c2
At point (0, -2),
c2 = -2
3x - y = 2
y = 3x - 3
f'(0) = 3
c1 = 3
Therefore, the required function is
f(x) = x^3 + 4x^2 + 3x - 2
Answer:
A= 29
B=34
C=117
Step-by-step explanation:
<u>A triangle has three sides and a triangle always adds up to be 180</u>
A + B + C = 180
B = A + 5
C = 4A + 1
Plug in.
A + A + 5 + 4A + 1 = 180
6A + 6 = 180
6A = 174
A = 29
<u>Now since you found A, find the other two by plugging A in!</u>
C = 4(29) + 1
C = 117
<u>Plug in the B equation</u>
B = 29 + 5
B=34
Check your answers
29 + 117 + 34 = 180
