Answer:

a) W(x) = 2, 000 - 275 x represents the given situation.

b) The cost of the computer after 6 years is $350.

Step-by-step explanation:

Initial worth of the company = $2,000

Depreciation each year = $275

Let, W(x) represent the worth of the computer in x - th year.

So, according to the question:

a) W(x) = 2, 000 - 275 x represents the given situation.

b) Solving W(x) for x = 6, we get

W(6) = 2,000 - 275(6) = 2, 000 - 1,650

= 350

⇒W(6) = $350

Hence, the cost of the computer after 6 years is $350.

Ally is analyzing a circle, y2 + x2 = 4, and a linear function g(x). Will they intersect?

Irina18 [472]

The linear function gives us the points
(0,3)
(4,0)
(8,-3)

find the equation
hm
find slope
(y2-y1)/(x2-x1)
for (0,3) and (4,0)
slope=(0-3)/(4-0)=-3/4

y=-3/4x+b
given
(0,3)
y=-3/4x+3

so sub -3/4x+3 for y in other equation
(-3/4x+3)^2+x^2=4
expand
9/2x^2-9/2x+9+x^2=4
11/2x^2-9/2x+9=4
times 2 both sides
11x^2-9x+18=8
minus 8 both sides
11x^2-9x+10=0
factor
or use quadratic formula
for
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

11x^2-9x+10=0
x= $\frac{-(-9)+/- \sqrt{(-9)^2-4(11)(10)} }{2(11)}$
x= $\frac{9+/- \sqrt{81-440} }{22}$
x= $\frac{9+/- \sqrt{-359} }{22}$
we see we have no real roots
there are no intersection points

Solve the given initial-value problem. the de is a bernoulli equation. x2 dy dx − 2xy = 4y4, y(1) = 1 2

mario62 [17]

$x^2\dfrac{\mathrm dy}{\mathrm dx}-2xy=4y^4$
$x^2y^{-4}\dfrac{\mathrm dy}{\mathrm dx}-2xy^{-3}=4$

Substitute $z=y^{-3}$ , so that $\dfrac{\mathrm dz}{\mathrm dx}=-3y^{-4}\dfrac{\mathrm dy}{\mathrm dx}$ . Then the ODE in terms of $z(x)$ is

$-\dfrac13x^2\dfrac{\mathrm dz}{\mathrm dx}-2xz=4$
$x^2\dfrac{\mathrm dz}{\mathrm dx}+6xz=-12$
$x^6\dfrac{\mathrm dz}{\mathrm dx}+6x^5z=-12x^4$

$\dfrac{\mathrm d}{\mathrm dx}\left[x^6z\right]=-12x^4$
$\implies x^6z=-\dfrac{12}5x^5+C$
$\implies z=-\dfrac{12}{5x}+\dfrac C{x^6}$
$\implies\dfrac1{y^3}=-\dfrac{12}{5x}+\dfrac C{x^6}$

and you can attempt to solve for $y$ explicitly from here if you wish.
In any case, given that $y(1)=\dfrac12$ (presumably that's what you meant to write), we'd get

$\dfrac1{\left(\frac12\right)^3}=-\dfrac{12}{5\cdot1}+\dfrac C{1^6}$
$8=-\dfrac{12}5+C\implies C=\dfrac{52}5$

giving a particular solution of

$\dfrac1{y^3}=-\dfrac{12}{5x}+\dfrac{52}{5x^6}$
