Make b the subject of the formula<br><br>A=1/2bh​
r-ruslan [8.4K]

Answer:

\blue{b = \dfrac{2A}{h}}

Step-by-step explanation:

A = \dfrac{1}{2}bh

Step 1. Switch sides.

\dfrac{1}{2}bh = A

Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.

2 \times \dfrac{1}{2}bh = 2 \times A

bh = 2A

Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.

\dfrac{bh}{h} = \dfrac{2A}{h}

Answer:

b = \dfrac{2A}{h}

Suppose that A is a nonsingular matrix with an eigenvalue λ. Show that 1/λ is then an eigenvalue of A-1 .
DiKsa [7]

Answer:

PROOF:

Suppose that A is an invertible non singular matrix.

Then,

Ax=\lambda x\\\\A^{-1}Ax=A^{-1}\lambda x\\\\\frac{1}{\lambda}x=A^{-1}x\\\\\lambda^{-1}x=A^{-1}x

This shows that if A is non singular invertible matrix ad if  λ is eigenvalue of A then  λ⁻¹ is eigenvalue of A⁻¹.
