<span>A bar graph or pie chart would be good visualization method to demonstrate how many observations of a certain value have been made. The bar graph and pie chart would also provide slightly different perspectives on the proportion of observed values recorded.</span>

Evaluate ∫SF⃗ ⋅dA⃗ , where F⃗ =(bx/a)i⃗ +(ay/b)j⃗ and S is the elliptic cylinder oriented away from the z-axis, and given by x2/

Norma-Jean [14]

Answer:

Therefore surface integral is $\pi(a^2+b^2)c-0-0=\pi(a^2+b^2)c$ .

Step-by-step explanation:

Given function is,

$\vec{F}=\frac{bx}{a}\uvec{i}+\frac{ay}{b}\uvec{j}$

To find,

$\int\int_{S}\vec{F}dS$

where S=A=surfece of elliptic cylinder we have to apply Divergence theorem so that,

$\int\int_{S}\vec{F}dS$

$=\int\int\int_V\nabla.\vec{F}dV$

$=\int\int\int_V(\frac{b}{a}+\frac{a}{b})dV$

$=\frac{a^2+b^2}{ab}\int\int\int_VdV$

$=\frac{a^2+b^2}{ab}\times \textit{Volume of the elliptic cylinder}$

$=\frac{a^2+b^2}{ab}\times \pi ab\times 2c=\pi (a^2+b^2)c$

If unit vector $\cap{n}$ directed in positive (outward) direction then z=c and,

$\int\int_{S_1}\vex{F}.dS_1=\int\int_{S_1} . dA$

$=\int\int_{S_1}.dA=0$

If unit vector $\cap{n}$ directed in negative (inward) direction then z=-c and,

$\int\int_{S_2}\vex{F}.dS_2=\int\int_{S_2}. -dA$

$=\int\int_{S_2}. -dA=0$

Therefore surface integral without unit vector of the surface is,

$\pi(a^2+b^2)c-0-0=\pi(a^2+b^2)c$

The sum of two numbers is −27. Their difference is −59. Find the numbers.

chubhunter [2.5K]

Question:

its asking about the difference between them

Answer Step:

since we gotta find the difference we going to subtract in order to find the difference -59 - -27

answer should be -32

correct me if im wrong.

Proving Vertical Angles Are Congruent

PSYCHO15rus [73]

Answer:

Statements: Reasons:

1) ∠2 and ∠4 are vertical angles given

2) limes <em>m </em>and <em>n </em>intersect at <em>P </em>definition of vertical angles

3) ∠3 and ∠4 are linear pair definition of linear pair

4) ∠2 and ∠3 are linear pair definition of linear pair

5) m∠3 + m∠4 =180 angle addition postulate

6) m∠2 + m∠3 =180 angle addition postulate

7) m∠2 + m∠3 = m∠3 + m∠4 substitution property

8) m∠2 = m∠4 subtraction property

9) ∠2 ≅ ∠4 definition of congruent(≅) angles
