Answer:
is the graph of 
shifted to the right by 
units.
Step-by-step explanation:
The given function is
The base function of this trigonometric function is
In general, the transformation 
will shift the graph of the base function, , k units to the right.
Therefore, is the graph of shifted to the right by units.
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:
she will need to get a 100 on the fourth test
Step-by-step explanation:
(252+x)/4 = 88
252+x = 352
x = 100
