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:
x = 5, x = -7
Step-by-step explanation:
If you mean find the roots, then x = 5 and x = -7
Because roots makes the equation equal to 0 and 5 - 5 = 0 and -7 + 7 = 0

Step-by-step explanation:
-3 ? 
-3 ? -3.8
-3 is greater than -3.8
i.e -3 > -3.8
Let
g(x)--------> the translation of the function f(x)
we know that
the rule of the translation is
units left and
units down
that means

so
In the function f(x) the point
is equal at the point
in the function g(x)
therefore
the function g(x) is equal to


<u>The answer is</u>
a) the rule of the translation is 
b) The graph in the attached figure
