Answer 7

no im having trouble with this one

Answer 8

\[

\left[
\begin{array}{cc}
5 & -1 \\
3 & 2 \\

\end{array}

\right]

\left[
\begin{array}{cc}
0 & -2 \\
3 & 1 \\

\end{array}

\right]

Answer 9

notice that the size of A is 2x2
and the size of B is 2x2

so the size of AB also will be 2x2

Answer 10

I got it already :) but I do need help on this one

Answer 11

you want to find \(\large s\) ?

Answer 12

I need to find the length s to nearest tenth

Answer 13

there is a direct formula :
```
arc length = (radius) * (angle)
```

Answer 14

simply multiply the radius and angle

Answer 15

she is probably wondering where the angle is

Answer 16

well there are many things to wonder about in that diagram, she better ask what she is wondering in her head lol

Answer 17

lol

Answer 18

if degrees, then
\[\frac{ 5\pi }{ 3 }=\frac{ 5 \times 180 }{ 3 } = 5 \times 60 = 300\]
\[s = \theta \times r = 300 \times 5\]

Answer 19

typo: correction
\[s = \theta \times r = 300 \times 6\]

Answer 20

degrees is a ridiculous unit, it was banned in calculus long time ago.. i feel geometry should also do the same :P

Answer 21

degrees is good i feel i don't like to work with radians and those pi's

Answer 22

if radian, then
\[s = \theta \times r = \frac{ 5\pi }{ 3 }\times 6=10\pi\]

Answer 23

\[10\pi=1800 = 6\times 300\]

Answer 24

thank you for your time and I hope you learned something

Answer 25

someday you gona ditch degrees im sure :)

1 revolution = 360 degrees
1 degree = 60 minutes
1 minute = 60 seconds

what the heck ?

Answer 26

who pulled these numbers 360 and 60, and from where ? LOL
