Below is the solution:
Rotating around the y-axis; solve for x.
<span>y = x/3
</span><span>x = 3y
</span>
<span>Find x^2
</span><span>x^2 = 9y^2
</span>
<span>Integrating it using the limits of 0 and 3, remember to add the pi and integrate 9y^2.
</span>
The answer is <span>81pi cubic units which is A. </span>
Answer:
x=-2 and -32/3
Step-by-step explanation:
|3x+19|=13
3x+19=13 and 3x+19=-13
x=-2 and x=-32/3
Divide 6 by -1. Remember that -y is really -1y.
Answer:
-1 is not correct
1 is the correct answer
Step-by-step explanation:
Her mistake was adding a negative sign in the one
The right way is to cross out one negative symbol between the two parentheses
Answer:
f(x) is linear
g(x) is exponential
Step-by-step explanation:
A linear function will always have the same rate of change between equally distant points, while an exponential function will have an increasingly large rate of change between equally distant points.
First, look at f(x). All these points are equally distant at 2 units apart on the x-axis, so they can be directly compared:

All of these points are the same distance apart on the y, so f(x) must be a linear function.
Now look at g(x). These are also all equally distant at only 1 unit apart.

These are very clearly not the same distance apart on the y, so g(x) must be the exponential function.
