Answer:
Choice C
Step-by-step explanation:
The quadrant in which an angle lies determines the signs of the trigonometric functions sin, cos and tan
If an angle Θ lies in quadrant IV, cos(Θ) is positive and both sin(Θ) and tan(Θ) are negative
Two of the trigonometric identities we can use are
1. and
2.
Using identity 1, we can solve for cos(s) and cos(t)
Since both angles lie in quadrant IV, both cos(s) and cos(t) must be positive so we only consider the positive signs of both values
Using identity 2, we can solve for cos(s-t)
Multiplying numerator and denominator of the first term by gives us the final expression as
Answer:
its 4
Step-by-step explanation:
Answer:People are able to hear footsteps because the sound made by a foot hitting the floor travels through the air to reach their ears. Is transmission
When light from the sun hits the sidewalk, the sidewalk becomes warmer. Is called absorption
Explanation:
Make sure you spell it right or it will not count it.
Answer:
-20 + 15g
Step-by-step explanation:
5 multiplied by -4 is -20
5 multiplied by 3g is 15 g.
because these two variables do not both have a g with them, this is the most they can be simplified. hope this helps!
