If a=[-2 -4 2 5 1 5 -1 -3 -4] and b=[2 3 -5 5 -4 2 -1 -1 3] find ba
Shalnov [3]

The product of A and B matrix will be option D; BA = \left[\begin{array}{ccc}16&10&39\\-32&-30&-18\\-6&-6&-19\end{array}\right].

<h3>What is the multiplication of matrix?</h3>

If A = \left[\begin{array}{ccc}-2&-4&2\\5&1&5\\-1&-3&-4\end{array}\right]and B = \left[\begin{array}{ccc}2&3&-5\\5&-4&2\\-1&-1&3\end{array}\right]

then,

BA = \left[\begin{array}{ccc}2&3&-5\\5&-4&2\\-1&-1&3\end{array}\right] \left[\begin{array}{ccc}-2&-4&2\\5&1&5\\-1&-3&-4\end{array}\right]

BA = \left[\begin{array}{ccc}16&10&39\\-32&-30&-18\\-6&-6&-19\end{array}\right]

Hence, the product of A and B matrix will be option D; BA = \left[\begin{array}{ccc}16&10&39\\-32&-30&-18\\-6&-6&-19\end{array}\right].

Use function notation to represent the area of a circle whose circumference is 103 cm
Nataly_w [17]

Circumference of the circle =103 cm

i.e., C = 2 \pi r = 103

i.e., r = \frac{103}{2 \pi}


Area of the circle is given by

A = \pi r^2

A = \pi (\frac{103}{2 \pi})^2

A = \pi (\frac{10609}{4 \pi^2})

A =\frac{10609}{4 \pi}

Therefore, the area of the circle is: A =\frac{10609}{4 \pi}  cm^2
