I asked before and didn’t get an answer I really don’t understand this thanks.
dmitriy555 [2]
The answer is D, because that is what you should get when you multiply it out.

4x^2 times x^2 = 4x^4 because...

1) multiply the 4 and the one in front of the x on the second term = 4 then

2) multiply x^2 times x^2 to get x^4, not x^3, so you can immediately eliminate A and B to save time.

Now let's deal with the second part..."may or may not be" part

A polynomial is an expression with more than two algebraic terms

terms are like...
2x + 3y ---there's two terms there, eventhough the 2 and x are multiplied, it doesn't count (same with the 3 and y)
since it only have two terms, not more than two terms, it is called a binomial, not polynomial. I think that's what they mean by that

one term with a variable (y,x,and so on) is called a monomial

one term with no var is called a constant

there's many more but hope this gave you some help

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate (in cm/min) at which the diameter d
rosijanka [135]

Answer:

0.0221 cm/min

Step-by-step explanation:

Surface area of a snowball:

An snowball has a spherical format.

The surface area of an sphere is given by:

A = 4\pi r^2

In which r is the radius(half the diameter). So in function of the diameter, we have that:

A = 4\pi (\frac{d}{2})^2 = \pi d^2

Implicit derivative:

To solve this question, we need to find the implicit derivative of A in function of t.

The variables are A and d, so:

\frac{dA}{dt} = 8\pi d \frac{dd}{dt}

Its surface area decreases at a rate of 5 cm2/min

This means that \frac{dA}{dt} = -5

Find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm

This is \frac{dd}{dt} when d = 9. So

\frac{dA}{dt} = 8\pi d \frac{dd}{dt}

-5 = 8\pi*9 \frac{dd}{dt}

\frac{dd}{dt} = -\frac{5}{72\pi}

\frac{dd}{dt} = -0.0221

This means that the diameter decreases at a rate of 0.0221 cm/min when the diameter is 9 cm.
