Answer:The answers are A and B (AE =CE, BAE=CDE)

Step-by-step explanation:

The solution to the expression a⁴ + b⁴ is 641 when a = 2 and b = 5

From the question, we have the following parameters that can be used in our computation:

a = 2

b = 5

Also, from the question, we have

a^4 + b^4

Express the exponents in the above expression properly

So, we have the following representation

a⁴ + b⁴

Substitute the known values in the above equation, so, we have the following representation

a⁴ + b⁴ = 2⁴ + 5⁴

Evaluate the exponents

'This gives

a⁴ + b⁴ = 16 +625

Evaluate the sum

'This gives

a⁴ + b⁴ = 641

Answer: The differential equations is

y3 3x3logx = 8x3.

Step-by-step explanation:

break the given original- value problem. The DE is homogeneous. xy2dy/ dx = y3- x3; y( 1) = 2.

result

Given a homogenous discriminational equation, xy2 dy/ dx = y3- x3

xy2dy/ dx = y3- x3

dy/ dx = ( y3- x3)/ xy2

dy/ dx = (( y/ x) 3- 1)/( y2/ x2)---( 1)

Put y/ x = v ⇒ y = xv

separatew.r.t x

dy/ dx = x.dv/ dx v

Equation( 1) becomes,

⇒ dv/ dx v = ( v3- 1)/ v2

⇒ dv/ dx = (( v3- 1)/ v2)- v

⇒ dv/ dx = ( v3- 1- v3)/ v2

v2. dv = -1/x.dx

Integrate on both sides, we get

∫ v2. dv = ∫- 1/x.dx

v3/ 3 = - logx C

1/3( y3/ x3)) log x = C( 2)

Now, given that y( 1) = 2

Substituting y = 2 and x = 1 in equation( 2)

(1/3) ×(23/13)) log 1 = C

C = 8/3

From equation( 2), we get

⇒( y3/ 3x3) logx = 8/3

thus, the needed differential equation is y3 3x3logx = 8x3.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Apply the Pythagorean theorem for the first triangle,

H² = x² - 6²

Apply the Pythagorean theorem for the second triangle,

B² = 27² - x²

Apply the Pythagorean theorem to the third triangle,

H² = 27² - x² - 21²

H² = -x² + 288

x² - 6² = -x² + 288

The equation of the line that passes through the point (6,-4) and is perpendicular to the line 2x - y = 5 is 5y + x = -14.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

Point (6,-4),

2x - y = 5,

Calculate the slope as the line is perpendicular to line 2x - y = 5

m = 2

The slope of the line perpendicular, m = - 1 / 5

Calculate the equation of the line as shown below,

[tex]y - (-4) = - 1 / 5 (x - 6)[/tex]

5 (y + 4) = -x + 6

5y + 20 = -x + 6

5y + x = -14

Therefore, the equation of the line that passes through the point (6,-4) and is perpendicular to the line 2x - y = 5 is 5y + x = -14.
