Can you guys plzzz help. This is precalc. I’m a senior
Eddi Din [679]

Answer:

1. \left[\begin{array}{ccc}-3&-8\\6&3\\2&8\end{array}\right]  , 2.  \left[\begin{array}{ccc}-8&-4&21\\-8&6&7\end{array}\right]

Step-by-step explanation

1. \left[\begin{array}{ccc}4&-3\\0&-1\\5&8\end{array}\right] - \left[\begin{array}{ccc}7&5\\-6&-4\\3&0\end{array}\right]

To solve just that each in the first matrix block and substract     with their equivalent in the second matrix block.  

For example 4 -7 = -3, -3-5= -8

\left[\begin{array}{ccc}-3&-8\\6&3\\2&8\end{array}\right]  

2. -2\left[\begin{array}{ccc}10&2&-3\\1&6&-5\end{array}\right]  + 3\left[\begin{array}{ccc}4&0&5\\-2&6&-1\end{array}\right]

Multiply first block with -2 and the second block by 3

\left[\begin{array}{ccc}-20&-4&6\\-2&-12&10\end{array}\right] + \left[\begin{array}{ccc}12&0&15\\-6&18&-3\end{array}\right]

Add just the same as question 1

\left[\begin{array}{ccc}-8&-4&21\\-8&6&7\end{array}\right]

The main formula is 

sector area = n / 360°  x Pi r²

4 = n / 360  x  r² = <span>n° / 36,

DedPeter [7]
Distance she rode the bike = 2 miles.

Distance she walks = 4 miles ( to Justin's home) + 6 miles ( from Justin's home to her home)  = 10 miles
