Kylie is training for an upcoming marathon and has committed to running more than 21 miles today. If she runs from her house, sh

e can run along two loops: a short path that is 3 miles in length, and a long path that is 6 miles in length. Select the inequality in standard form that describes this situation. (x = the number of loops on the short path, y = the number of loops on the long path).

If the integral is simply

\displaystyle\int(x^3-6x^2+9x+3)(3x^2-12x+9)\,\mathrm dx

then notice that

\mathrm d(x^3-6x^2+9x+3)=(3x^2-12x+9)\,\mathrm dx

which means you can compute the integral easily with a substitution

u=x^3-6x^2+9x+3\implies\mathrm du=(3x^2-12x+9)\,\mathrm dx

Under this transformation, the integral is

\displaystyle\int u\,\mathrm du=\frac{u^2}2+C=\boxed{\frac{(x^3-6x^2+9x+3)^2}2+C}

On the other hand, in case you're missing a symbol and the integral is actually

\displaystyle\int\frac{x^3-6x^2+9x+3}{3x^2-12x+9}\,\mathrm dx

then first carry out the division:

\dfrac{x^3-6x^2+9x+3}{3x^2-12x+9}=\dfrac x3-\dfrac23-\dfrac{2x-9}{3x^2-12x+9}

Now, 3x^2-12x+9=3(x-3)(x-1), so to integrate the remainder term you can decompose it into partial fractions:

-\dfrac{2x-9}{3(x-3)(x-1)}=\dfrac a{x-3}+\dfrac b{x-1}

9-2x=a(x-1)+b(x-3)

x=1\implies7=-2b\implies b=-\dfrac72

x=3\implies3=2a\implies a=\dfrac32

\implies-\dfrac{2x-9}{3(x-3)(x-1)}=\dfrac 3{2(x-3)}-\dfrac 7{2(x-1)}

Then the integral would be

\displaystyle\int\frac{x^3-6x^2+9x+3}{3x^2-12x+9}\,\mathrm dx=\boxed{\frac{x^2}6-\frac{2x}3+\frac32\ln|x-3|-\frac72\ln|x-1|+C}

which can be rewritten in several ways, such as

\dfrac{x^2-4x}6+\dfrac12ln\left|\dfrac{(x-3)^3}{(x-1)^7}\right|+C

You want to create a piece of
emmainna [20.7K]

After six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.

<h3>What is Rate ?</h3>

Rate is a measure or quantity measured against another quantity or measure which is the ratio between two related quantities in different units

It is given that you want to create a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. The costs at two studios are shown.

  • Studio A: $8 per hour.
  • Studio B: $6.50 per hour.

Multiply both together. That is,

8 x 6.5 = $52

The two cost will be the same at $52. By that time,

Studio A will be six and half hours.

Studio B will be eight hours.

Therefore, after six and half hours for studio A and after eight hours for studio B, the total costs of both studios will be the same.

Kipish [7]

Answer:

5774.61

Step-by-step explanation:

The method to calculate car value use :

P(x)= car price ( 1 - rate percentage )^years

P(x)= 18,995 ( 1 - 0.18 )^6

= 5774.60672

Round to nearest hundreds:

= 5774.61
