Answer: C is no and the others are yes.
Step-by-step explanation:
Answer:
y = -(1/3)x -2
Step-by-step explanation:
For each horizontal "run" of 3 units, the "rise" of the line is -1 unit. Hence the slope is ...
rise/run = -1/3
The y-intercept is where the line crosses the y-axis, at y = -2. So, the slope-intercept form of the equation of the line is ...
y = (slope)·x + (y-intercept)
y = -1/3x -2
X^2 +2x-24
C is the answer
V=(1/3)πr²h
∴ dV/dt
=(π/3)[r²(dh/dt)+h2r(dr/dt)]
=(π/3)[(30)²(-2)+40(2)(30)(2)]
=(π/3)[-1800+4800]
=1600π in³/sec
Answer: 1600π in³/sec
