Answer:
infinite number of solutions
Step-by-step explanation:
x+y=1
3y=-3x+3 ⇒ y=-x+1 ⇒ y+x=1
both equations are the same, so they have infinite number of solutions
A² + 2ab + b² = (a+b)²<span>
</span><span>
So we get
</span><span>16j</span>² + 24j + 9 = (4j+3)²
Answer:
The radius is increasing at a rate of approximately 0.044 in/s when the diameter is 12 inches.
Because
the radius is changing more rapidly when the diameter is 12 inches.
Step-by-step explanation:
Let
be the radius,
the diameter, and
the volume of the spherical balloon.
We know
and we want to find 
The volume of a spherical balloon is given by

Taking the derivative with respect of time of both sides gives

We now substitute the values we know and we solve for
:



The radius is increasing at a rate of approximately 0.044 in/s when the diameter is 12 inches.
When d = 16, r = 8 and
is:

The radius is increasing at a rate of approximately 0.025 in/s when the diameter is 16 inches.
Because
the radius is changing more rapidly when the diameter is 12 inches.
8 / 4+4
8/8
=1
