Answer:

I couldn't find the link you wanted me to click.

Anyway the Pyramid Volume Formula is

Volume= (Area of the Base * Height) ÷ 3

It's hard to determine the volume because I can't tell the dimensions from the graphic.

I'd guess the answer to question 4 is "A" means area of the base

The area of the triangle is
  A = (1/2)bh
  = (1/2)(3 ft)(6 ft)
  = 9 ft^2

That triangular area is not carpeted, so the carpet area is
  72 ft^2 -9 ft^2 = 63 ft^2.

What’s the differential equation of

worty [1.4K]

Answer:

$y=\frac{1}{x^{2}-6x+13 }$

Step-by-step explanation:

We have given,

$\frac{dy}{dx}=y^{2}(6-2x)$

and initial condition $x=3,\ y=\frac{1}{4}$

Now,

$\frac{dy}{dx}=y^{2}(6-2x)$

Rearranging the variables, we get

$\frac{dy}{y^{2} }=(6-2x).dx$

Applying integration both sides, we get

$\int\ {\frac{dy}{y^{2} } } \,=\int\ {(6-2x).} \, dx$

⇒ $\frac{-1}{y} =6x-\frac{2x^{2} }{2}$

⇒ $\frac{-1}{y}=6x-x^{2} +C$

Putting the initial condition (i.e., $x=3,\ y=\frac{1}{4}$ ), we get

⇒ $-4=6\times3-(3)^{2}+C$

⇒ $-4=18-9+C$

∴ $C=-13$

We have, $\frac{-1}{y}=6x-x^{2} +C$

now putting the value of $C$ in above equation, we get

⇒ $\frac{-1}{y}=6x-x^{2} -13$

⇒ $\frac{1}{y}=-6x+x^{2} +13$

$y=\frac{1}{x^{2}-6x+13 }$

You can distribute the 4, and you get:
$4(10) +18 = 40+18$

Then add to get your answer:
$40+18 = 58$
