Step-by-step explanation:

<em>perimeter </em><em>=</em><em> </em>

<em>2</em><em>(</em><em>L+</em><em>B)</em>

<em>=</em><em>2</em><em>×</em><em> </em><em>(</em><em>7</em><em>z</em><em>+</em><em>3</em><em> </em><em>+</em><em>3</em><em>z</em><em>+</em><em>5</em><em>)</em>

<em>2</em><em>×</em><em>1</em><em>0</em><em>z</em><em> </em><em>+</em><em>8</em>

<em>=</em><em>2</em><em>0</em><em>z</em><em>+</em><em>1</em><em>6</em>

Answer:

Therefore,

l(AB) = 15 units

Step-by-step explanation:

Given:

AD = DC

angle DBA = angle DBC = 90°

AB = 5x

CB = 4x - 3

To Find:

AB = ?

Solution:

In  Δ ABD and Δ CBD

AD ≅ DC     ……….{Given}

∠ DBA ≅ ∠ DBC      …………..{measure of each angle is 90° given}

DB ≅ DB                  ....……….{ Reflexive property}

Δ ABD ≅ Δ CBD      ..........….{By Hypotenuse Leg Theorem}

∴ AB ≅ CB               ..............{corresponding sides of congruent triangles}

on substituting the values we get

5x=4x+3\\\\5x-4x=3\\\\\therefore x =3

Now we require AB

AB=5x\\\\AB=5\times 3\\\\AB=15\ units

Therefore,

l(AB) = 15 units

Find all values of m so that the function y = xm is a solution of the given differential equation. (Enter your answers as a comm
blagie [28]

Answer:

m = 6,9  

Step-by-step explanation:

We are given that y = x^m is a solution to given differential equation.

x^2y'' - 14xy' + 54y = 0  

First we 3evaluate the value of:

y'' = m(m-1)x^{(m-2)}

y' = mx^{(m-1)}

Putting these value in the above differential equation, we get,

x^2m(m-1)x^{(m-2)} + 14xmx^{(m-1)} + 54x^m = 0

x^m[m(m-1) -14m + 54] = 0

x^m(m^2 - 15m + 54) = 0

(m^2 - 15m + 54) = 0

(m-9)(m-6) = 0

m = 9,6

Thus, for m = 9,6 , the function y = x^m is a solution of given differential equation.
