he function C(x) = 400x – 0.2x2 represents the total costs for a company to produce a product, where C is the total cost in doll

liq [111]

To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0.
C(x) = 400x - 0.2x²
dC(x) / dt = 400 - 0.4 x = 0
The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation,
C(x) = (400)(1000) - 0.2(1000²) = $ 200,000
Thus, the answer is letter B.

Write the equation of a circle with center (4, -5) and radius = square root of 13

Anon25 [30]

<h2>Hello!</h2>

The answer is:

The equation of the given circle is:

$(x-4)^{2}+(y+5)^{2}=13$

The equation of a circle is given by the following equation:

$(x-h)^{2} +(y-k)^{2}=r^{2}$

We are given the center point (4,-5) and the radius.

So,

Where:

$h=x=4\\k=y=-5\\r=\sqrt{13}$

Then, substituting into the circle equation, we have:

$(x-4)^{2} +(y-(-5))^{2}=(\sqrt{13})^{2}$

Hence, the simplified equation of the circle is:

$(x-4)^{2}+(y+5)^{2}=13$

Have a nice day!

Can someone find out the answer to this question please, in the image below

I can see why your confused, but the range of the function is <u>y≤−1 or y≥1</u> . The graph of the cotangent function looks like this: The domain of the function <u>y=cot(x)=cos(x)sin(x)</u> is all real numbers except the values where <u>sin(x)</u> is equal to 0 , that is, the values <u>πn for all integers n</u> .

<em>Hope this helps</em>

Have a great day!
