The correct answer is A, -3 degrees Celsius.
Step-by-step explanation:
this creates a right-angled triangle.
the right angle (90°) being the angle between flag pole and ground.
the angle ground-wire is 50°.
because we know that the sum of all angles in a triangle is always 180°, we know then that the angle flagpole-wire is
180 - 90 - 50 = 40°
so, we have the situation to know 1 side and all angles.
to get the other sides we use best the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and related angles are always opposite of each other.
in our case now we have
24/sin(50) = wire/sin(90) = wire/1 = wire = 31.32977494... ft
so, the rounded answer is that the wire must be
31.3 ft long
Answer:
Sin(t) =
and 
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that
then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin(
) = 
Hello!
This question is an example of function composition.
Given, f(x) = 3x - 5, find f(x - 1). For this problem, we substitute x for (x - 1).
f(x - 1) = 3(x - 1) - 5
f(x - 1) = 3x - 3 - 5
f(x - 1) = 3x - 8
Therefore, the answer is choice D, f(x - 1) = 3x - 8.
