The figure below shows three uniform objects: a rod with m1 = 7.00 kg, a right triangle with m2 = 3.70 kg, and a square with m3
= 5.30 kg. their coordinates in meters are given. determine the center of gravity for the three-object system.

Answer:
see explanation
Step-by-step explanation:
Using sum to product identities
cos x - cos y = - 2sin( )sin(
) = 2sin(
)sin(
)
cos x + cos y = 2cos( )cos(
)
Note that
sin10° = sin(90 - 10)° = cos80°
Thus
← cancel 2 from numerator/ denominator
= ×
= tan45° × tan35° { tan45° = 1 ]
= 1 × tan35°
= tan35° ← as required
Answer:
slope = if it were in an
Step-by-step explanation:
the graph is a negative and will therefore have a negative slope. to find the slope, pick a point on the graph and find the .
for instance, start with the point (0,1). Then go down 1 and left 2 to get to the next point on the graph (2,0). 1 is the "rise" and 2 is the "run" hence -1/2 being the slope.
you could also use the slope formula:
point 1: (0,1) (x₁ ,y₁)
point 2: (2,0) (x₂ , y₂)
