Given the following matrices A and B, find an invertible matrix U such that UA = B:

1 answer:

3 0

<span>A and B must be invertible, we have UA=B, since A is invertible. A^-1 exists, by multiplying with A^-1, we have UA A^-1 =B A^-1. But AA^-1 = I (identity matrix) and XI=X, for all matrix X, we find UI= B A^-1, and U= B A^-1.</span>

We have to calculate the pizza´s area.
r=radius
Area (circle)=π*r²
diameter=30 cm
radius=diameter/2=30 cm/2=15 cm

Area(pizza)=π*(15 cm)²=225π cm²≈706.86 cm².

solution: 706.86 cm²
