Which is equivalent to cos-1(0.17)? Round your answer to the nearest hundredth of a radian.

1 answer:

4 0

Let
cos A------> 0.17
then
A=arc cos (0.17)------> A=80.212°

convert degrees to radians
pi radians is equal to-----------> 180°
x-------------------------> 80.212°
x=80.212*pi/180-----> x=1.40 radians

the answer is
1.40 radians

I think just two reflections would do it.

First we reflect around y = -x, the 45 degree line through the origin and the second and fourth quadrant.

Then we reflect through the y axis, x=0.

The composition of the two reflections is equivalent to a 90 degree clockwise rotation.

3. (02.01 LC) simplify [-3 over 5] ÷ [7 over 6]A.-7 over 10B.-18 over 35C.18 over 35D7 over 10

Alex

For this case we want to do the following operation:

-3/5 divided by 7/16 and we can do this:

$-\frac{3}{5}\cdot\frac{6}{7}=-\frac{18}{35}$

And then we can simplify and we got:

$-\frac{18}{35}$
