Answer:

180 - 41 - 43 = 96

Savatey [412]3 years ago

Answer:

x = 96

Step-by-step explanation:

The sum of the angles of the triangles is 180 degrees.

41+43 +x = 180

Combine like terms

84+x = 180

Subtract 84 from each side

84-84 +x = 180-84

x = 96

Evaluate the surface integral ∫ ∫ₛ G(x, y, z) dS using a parametric description of the surface. G (x, y, z ) = 2z² ​, over the h
mixas84 [53]

Answer:

Step-by-step explanation:

Given the surface

G(x, y, z) =2z²

Over the hemisphere

x² + y² + z² = 36. For z≥0

Using polar coordinate

x=sin Φ cos θ,

y = sin Φ sin θ,

z = cos Φ

0 ≤ Φ ≤ π/2, 0 ≤ θ ≤ 2π

Therefore

r(Φ, θ) = sin Φ cos θ i + sin Φ sin θ j + cos Φ k

Also, dS= |rθ×rΦ|= sinΦ

dS=sinΦdΦdθ

Then we want to compute the volume integral of

∫ ∫ₛ G(x, y, z) dS

G(x, y, z) =2z²

Therefore in polar forms

G(x, y, z) =2(cos Φ)²

G(x, y, z) = 2cos²Φ

Given that dS=sinΦdΦdθ

∫ ∫ₛ G(x, y, z) dS

∫ ∫ 2cos²ΦsinΦdΦdθ at 0 ≤ Φ ≤ π/2,

0 ≤ θ ≤ 2π

∫ 2cos²ΦsinΦ •θdΦ from 0 ≤ θ ≤ 2π

2∫cos²ΦsinΦ •(2π-0)dΦ

4π∫ cos²ΦsinΦ dΦ from 0 ≤ Φ ≤ π/2

Let U = cosΦ

dU/dΦ =-sinΦ

-dU/sinΦ =dΦ

4π∫ U²sinΦ(-dU/sinΦ) 0 ≤ Φ ≤ π/2

-4π∫ U² dU

-4π U³/3, then U=cosΦ

[-4πcos³Φ / 3 ] from 0 ≤ Φ ≤ π/2

[-4π cos³(π/2)/3 - [-4π cos³(0)/3]

0+4π/3

4π/3

4π/3 unit²

How would you graph the solution if your inequality was I is less than or equal to 11.25?
larisa86 [58]

1 \leqslant 11.25
Depending on the scenario you would either shade everything in between these two points or it can be any real number/ point on the graph.

There isn't much info to go on how they visually want to see it.

Like you could easily graph this as a number line and shade everything from 1 to 11.25 and put a solid dot on both sides.

If y= 1/5 when x=3, find y when x=4, given that y varies directly with x
lisov135 [29]

Answer:

<h2>y =  \frac{4}{15}</h2>

Step-by-step explanation:

To find y when x=4, we must first find the relationship between them

The statement

y varies directly with x is written as

<h3>y  \:  \:  \:  \alpha  \: \:   \: kx</h3>

where k is the constant of proportionality

From the question

when y = 1/5

x = 3

Substitute the values into the above formula and solve

That's

<h3>\frac{1}{5}  = 3k \\ 15k = 1 \\ k =  \frac{1}{15}</h3>

So the formula for the variation is

<h3>y =  \frac{x}{15}</h3>

From the question

when x = 4

<h3>y =  \frac{4}{15}</h3>

Hope this helps you
