Answer:
-21.79.
Step-by-step explanation:
(-10.5 + m) / 11.57 = -2.748
(-10.5 + m) = -2.748 (11.57)
-10.5 + m = -31.794
m = -31.794 + 10.5 = -21.79.
For easy answers, I find a graphing calculator very helpful.
(a) f is increasing on (-∞, -1) and on (9, ∞). You may be expected to use the union of these two intervals to describe "the interval on which f is increasing":
(-∞, -1) ∪ (9, ∞)

Answer:
D, B
Step-by-step explanation:
Remember SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
In the first triangle, for angle A, 11 is the adjacent leg, 60 is the opposite leg, and 61 is the hypotenuse. Therefore:
sin A = 60/61 = 0.98
cos A = 11/61 = 0.18
tan A = 60/11 = 5.45
So the correct answer is D.
In the second triangle, for angle Y, 16 is the adjacent leg and 65 is the hypotenuse. To find the sine, we need to know the opposite leg. So first, use Pythagorean theorem to find the opposite leg.
c² = a² + b²
65² = 16² + b²
4225 = 256 + b²
b² = 3969
b = 63
So the sine of Y is:
sin Y = 63 / 65
Answer B.
