Thinking about the graph of f(x), the rate of change is zero whenever there is an extremum.
First, differentiate f(x)

Next, find the zeros of f'(x) by factoring.

Now, we substitute these x-values into the
original equation to find the coordinates.
(-2.667, 11.481), (0, 2)
Answer:
1.9099
Step-by-step explanation:
V = (PI) * r^2 * (h/3)
32 = (PI) * (16) * (h/3)
6/PI = h
1.9099 = h
Subsitution method.

Y=3x - 11
</span><span>Y= -3x - 2
</span>
-3x - 2 = 3x - 11
+3x +3x
-2 = 6x - 11
+11 +11
6x = 9
x = 1.5
<span>Y=3(1.5) - 11
</span>y = 4.5 - 11
y = -6.5
Now we have our points.
Answer: x = 1.5 and y = -6.5
Answer:
question 9
92/11 or 8.36
Step-by-step explanation:
angle on straight line is 180
:. 10x+1 + 12x-5 = 180
collect like terms
10x+12x = 180+5-1
22x = 184
divide both sides by the coefficient of x
22x/22 = 180/22
:. x = 180/22(to d lowest form= 92/11)
or 8.36
