Y = 4/3(x) + 1/3
Divide both sides by 3
1 minute = 60 seconds
3 minutes= 180 seconds
multiply 200 x 180= 36,000 beats
hope this helps
Ok, so you want us to find theta when

we know from our unit circle that when the angle is 45 degrees, cos(45°)=sin(45°)=

also we can find this by the special 45-45-90 triangle
when Θ=45°, cos(Θ)=
Know the properties of each shape:
A square has all sides of equal length plus all corners are right angles
A rectangle has all right angles, but has two pairs of parallel sides
A parallelogram is a quadrilateral that has two pairs of parallel sides
A rhombus is where all sides are equal length, but no right angles at all
So the best choice given the diagram is C: parallelogram
Hope this helped you to understand better.
