Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = and tan60° =
, then
sin60° = =
=
( cross- multiply )
x = 4
( divide both sides by
)
x = 4
and
tan60° = =
=
( multiply both sides by y )
y = 2
( divide both sides by
)
y = 2
Answer:
Step-by-step explanation:
The two ringtones will cost her a total of and is a fixed amount. The relationship between the cost and number of songs only is
and therefore the answer is
. You can also directly find the answer by finding the y-intercept (in this case
), as no other answer choices include the term
, so A must be the correct answer.
Answer: Option D
phase
Step-by-step explanation:
By definition, the cosine function has the following form
Where is known as the phase angle
By definition the sinx function is equal to the cosx function with a phase shift of
So if we have the function
and we want to transform it into the function
then
Finally
the answer is the option D
