V = Bh/3
V = 15 x 28 / 3
V = 420 / 3
V = 140 in^3
Answer:
4√3 according to khan academy
Step-by-step explanation:
The derivative of f(x) at x=3 is 2x=6 approaching from the left side (apply power rule to y=x^2). The derivative of f(x) at x=3 is m approaching from the right side. In order for the function to be differentiable, the limit of derivative at x=3 must be the same approaching from both sides, so m=6. Then, x^2=mx+b at x=3, plug in m=6, 9=18+b, so b=-9.
B. because when you multiply the factors they will get B
