Answer:
0.0000454
Step-by-step explanation:
The zeros are not significant since they come before the numbers greater than 0. And I rounded 3 to 4 since the 8 was above 5 so it gets rounded up
Last one!
explanation is I remember having this question and studying this bad in middle school :)
Answer:
B) The scale on the y-axis could be changed to 25–40.
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.
