a doggy daycare costs $2000 a month to operate. and it spends $200 each month for every dog that it watches. the daycare charges
Luba_88 [7]
f(n)= 300n - 2000
this function would count the profit of a month. To get the profit of longer periods you would need to do something like this:
[text]g(t) = t * f(n)[/text] where t is time.

I constructed the first function by simply looking at how much would one dog give profit. Since the fee is 500 and 200 of it is going to be spent away, 300 is left. So, profit from one dog is 300 dollars. However, if they don't have enough dogs, the doggy daycare company would get in debt because of 2000 dollars that it needs a month to operate, that's why I subtracted 2000 from the profit.

Please differentiate this problem
strojnjashka [21]

Answer:

dy/dx = d/dx sin(x-3/x+2)

dy/dx = cos(x-3/x+2) . d/dx (x-3/x+2)

dy/dx = cos(x-3/x+2) . (x + 2 - x + 3)/(x+2)²

dy/dx = [5cos(x-3/x+2)]/(x + 2)²

Step-by-step explanation:

<u>Step 1:  Find the probability of choosing a 1</u>

1 out of 6 → 1/6

<u>Step 2:  Find the probability of choosing a blue chip.</u>

2 out of 6 → 2/6 → 1/3

<u>Step 3:  Multiply it</u>

1/6 * 1/3

1/18

Answer: 1/18 or 0.0555... or %5.555...

Which equation does this image represent?
nirvana33 [79]

Given:

Image of the ellipse

To find:

The equation of the image

Solution:

The given image is a ellipse.

Center of the ellipse = (0, 0)

x-axis points are (-3, 0) and (3, 0).

y-axis points are (2, 0) and (-2, 0).

Standard form of equation of ellipse:

$\frac{(x-h)^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}}=1

where (h, k) is the center = (0,0)

a is the point on x-axis where y = 0. Hence a = 3.

b is the point on y-axis where x = 0. Hence b = 2.

Substitute this in the standard form of ellipse.

$\frac{(x-0)^{2}}{3^{2}}+\frac{(y-0)^{2}}{2^{2}}=1

$\frac{x^{2}}{9}+\frac{y^{2}}{4}=1

To make the denominator same multiply 1st term by \frac{4}{4} and 2nd term by \frac{9}{9}.

$\frac{4x^{2}}{4\times9}+\frac{9y^{2}}{9\times4}=1

$\frac{4x^{2}}{36}+\frac{9y^{2}}{36}=1

$\frac{4x^{2}+9y^{2}}{36}=1

Multiply by 36 on both sides

$\frac{4x^{2}+9y^{2}}{36}\times 36=1\times 36

${4x^{2}+9y^{2}}={36}

The equation of the image is ${4x^{2}+9y^{2}}={36}.
