Answer:

a=35, b=14, c=5

Step-by-step explanation:

b+6=20, b+6-6=20-6, b=14

4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5

Answer:

A = 35°

B = 14

C = 5

Step-by-step explanation:

So to start we must assume that noth triangles are the exact same triangle.

to find A we must add up all angles to total 180°

angle A + angle B + angle C = 180°

A + 55° + 90° = 180°

A + 145° = 180°

-145° = -145°

A = 180° - 145°

A = 35°

to find B

B + 6 = 20

-6 = -6

B = 20 - 6

B = 14

to find C

4c - 6 = 14

+ 6 = +6

4c = 20

÷4 = ÷4

C = 20 ÷ 4

C = 5

Consider the differential equation x^2 y''-xy'-3y=0. If y1=x3 is one solution use redution of order formula to find a second lin

Anastasy [175]

Suppose $y_2(x)=y_1(x)v(x)$ is another solution. Then

$\begin{cases}y_2=vx^3\\{y_2}'=v'x^3+3vx^2//{y_2}''=v''x^3+6v'x^2+6vx\end{cases}$

Substituting these derivatives into the ODE gives

$x^2(v''x^3+6v'x^2+6vx)-x(v'x^3+3vx^2)-3vx^3=0$

$x^5v''+5x^4v'=0$

Let $u(x)=v'(x)$ , so that

$\begin{cases}u=v'\\u'=v''\end{cases}$

Then the ODE becomes

$x^5u'+5x^4u=0$

and we can condense the left hand side as a derivative of a product,

$\dfrac{\mathrm d}{\mathrm dx}[x^5u]=0$

Integrate both sides with respect to $x$ :

$\displaystyle\int\frac{\mathrm d}{\mathrm dx}[x^5u]\,\mathrm dx=C$

$x^5u=C\implies u=Cx^{-5}$

Solve for $v$ :

$v'=Cx^{-5}\implies v=-\dfrac{C_1}4x^{-4}+C_2$

Solve for $y_2$ :

$\dfrac{y_2}{x^3}=-\dfrac{C_1}4x^{-4}+C_2\implies y_2=C_2x^3-\dfrac{C_1}{4x}$

So another linearly independent solution is $y_2=\dfrac1x$ .

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Geometry

Area of a Circle: A = πr²
d = 2r

Step-by-step explanation:

Step 1: Define

d = 4 m

Step 2: Find r

Substitute: 4 = 2r
Isolate r: 2 = r
Rewrite: r = 2 m

Step 3: Find Area

Substitute: A = π(2)²
Substitute: A = (3.14)(2)²
Evaluate: A = (3.14)(4)
Multiply: A = 12.56 m²
