You will circle 4.5 on the number line. it should be an open circle going to the left side.
THis will be the coordinates of the point at a turning point on the graph.
Since the second derivative is positive (=1) it will be a minimum value of f(x).
477900 there you go use a calculator next time ;)
Answer:
Step-by-step explanation:
This will result in cylinder with radius of 4 and height of 3.
<u>Total surface area:</u>
- S = 2πr² + 2πrh = 2π(4² + 4*3) = 2π*28 = 56π
Answer:
x in (-oo:+oo)
y = (-2/3)*x+1 // - (-2/3)*x+1
y-((-2/3)*x)-1 = 0
(2/3)*x+y-1 = 0
2/3*x+y-1 = 0 // - y-1
2/3*x = -(y-1) // : 2/3
x = (-(y-1))/2/3
x = 3/2*(1-y)
x = 3/2*(1-y)
(hope that helps you out :)
