Answer:
pretty sure its the first one but i may be wrong!
Answer:
0.333 units³
Step-by-step explanation:
Think process:
The equation is given as y =
Let, y = f (x)
Therefore,
We know that the limits are y-axis and x= 3
Y-axis: x= 0
then limits are given as x= 0 and x = 3
Integrating gives:
= + C
calculating from x= 0 to x = 3, we know volume is given by
= [ ]
= [0.000041136 + 1/3]
= 0.333 units³
y = -8x + 5
To obtain the equation we require a point on it and it's slope.
the slope m = dy/dx at x = 1
dy/dx = -2-6x
x = 1 then dy/dx = -2 -6 = -8
equation of line in form y - b = m(x-a) with m = -8 and (a,b)=(1,-3)
y + 3 = -8(x-1)
y + 3 =-8x + 8
⇒ y = -8x +5 is the equation of the tangent
