Write five other iterated integrals that are equal to the given iterated integral. 8 0 x2 0 y f(x, y, z) dz dy dx 0
mash [69]

An iterated integral is the outcome of taking integrals toward a function of more than one variable in such a way that part of the variables is treated as constants for each of the integrals.

From the given parameters, we are to write out five iterations for a triple integral;

\mathbf{\int ^8_0\ \int^{x^2}_{0} \  \int^y_0 \ \  f(x, y, z)  \ dz dy dx }

where;

  • the region is bounded by 0 ≤ z ≤ y, 0 ≤ y ≤ x², 0 ≤ x ≤ 8.

Thus, since x, y, z are functions of at least one variable, we can have the following iterations:

  • \mathbf{\int^{64}_{0} \ \int^{8}_{\sqrt{y}} \ \int^{y}_{0} \ \ f(x,y,z) dz dxdy}

  • \mathbf{\int^{64}_{0} \ \int^{y}_{0} \ \int^{8}_{\sqrt{y}} \ \ f(x,y,z)\ dxdzdy}  

  • \mathbf{\int^{64}_{0} \ \int^{64}_{z} \ \int^{8}_{\sqrt{y}} \ \ f(x,y,z)\ dxdydz}

  • \mathbf{\int^{8}_{0} \ \int^{x^2}_{0} \ \int^{x^2}_{z} \ \ f(x,y,z)\ dydzdx}  

  • \mathbf{\int^{64}_{0} \ \int^{8}_{\sqrt{z}} \ \int^{x^2}_{z} \ \ f(x,y,z)\ dydxdz}

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 11 feet. The width of
valentina_108 [34]

Answer:

A = x(x − 4) − 0.5(8)(x − 4) − 3(7)

Step-by-step explanation:

x = length, making the width (x-4)

The stage closet will be (x-4)(8)(1/2)

The rectangle is 7(3)

That makes the painted area x(x-4) - 4(x-4)

So...

A = x(x − 4) − 0.5(8)(x − 4) − 3(7)

Which equation can be used to determine the reference angle, r, if 0=7pi/12?
TEA [102]
The answer is "<span>r=pi-theta".
</span>
The reference angle refers to the angle that the given edge or angle makes with the x-pivot.  Regardless where the angle closes or ends, it does mot matter where the terminal side of the angle is located, the reference angle measures the nearest distance of that terminal side to the x-axis.

densk [106]
6 right ? because if it’s three hours after 2 then that would mean it’s 5 and one more hour after that meaning it’s 6.

unless your asking what’s one hour after 2 meaning it would be 3.
