Answer:
Step-by-step explanation:
cos^-1(6/13)=62.5136°
sin(2*62.5136°)=0.8189
cos(2*62.5136°)=-0.5740
Answer:
(2,3)
Step-by-step explanation:
Rotation through 90 clockwise gives the expression
<em>(</em><em> </em><em>x</em><em> </em><em>,</em><em> </em><em>y</em><em> </em><em>)</em><em>_</em><em>_</em><em>_</em><em> </em><em>(</em><em> </em><em>y</em><em> </em><em>,</em><em>-</em><em> </em><em>x</em><em> </em><em>)</em>
<em>so</em><em> </em><em>whe</em><em>n</em><em> </em><em>you</em><em> </em><em>pu</em><em>t</em><em> </em><em>the</em><em> </em><em>poin</em><em>ts</em><em> </em><em>-</em><em>3</em><em> </em><em>,</em><em>2</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>relat</em><em>ion </em><em>,</em><em> </em><em>it</em><em> </em><em>becom</em><em>es</em>
( -3 , 2 ) ___ ( 2, - -3 )
= ( x, y ) __ ( 2, 3 ). meaning when you rotate -3,2 through 90 clockwise you will get the image ( 2 ,3 )
Answer:
8 hours
Step-by-step explanation:
In 2 hours, the clerical secretary can do 1/4 of the job. (The executive secretary does 3/4 of the job - or 3 times as much - in the same 2 hours.)
Since it takes the clerical secretary 2 hours to do 1/4 of the job, it will take them four times that to do it themselves. 2x4=8.
Range show how low and high the data is and thus shows the variability.
1. 2/2 - 1/2=1/2
2. 3/4-2/4=1/4
3. 2/4-1/4=1/4
4. 4/6-2/6=2/6
Are you you learning about subtracting fractions?
I’m pretty sure this is it, and you would shade in the parts that are left in the other circles.
