Answer:
61.97 feets
Step-by-step explanation:
Using trigonometry :
Horizontal distance between the person and building,
Let distance = d
Tan 15 = 15 / d
0.2679491 * d = 15
d = 15 / 0.2679491
d = 55.980781
To obtain the height, h :
tan 40 = (h-15)/d
d = 55.98
h-15 = 55.98 (tan 40°)
h - 15 = 55.98 * 0.8390996
h - 15 = 46.972797
h = 46.972797 + 15
h = 61.972797
h = 61.97 feets
Answer: C
y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.

Answer:
They must mix
37 pounds of the House Blend
3 pounds of the Kenya Blend.
Step-by-step explanation:
Let 'x' be House coffe and 'y' be Kenya Coffee. Then:
10.50x + 12.80y = 10.67(40)
Also, we knw that:
x + y = 40
Solving the system of equations above, we have that:
x ≈37.0435 ≈ 37 pounds
y ≈2.95652 ≈ 3 pounds
They must mix
37 pounds of the House Blend
3 pounds of the Kenya Blend.
Answer:
Step-by-step explanation:
You would first need to find the slope. The Slope formula is m = (y2 - y1)/(x2 - x1). In your problem, (1, 2) could be (x1, y1) and (2, 5) could be (x2, y2). Substitute those values into the Slope formula to find m which is your slope.
The point-slope form of a line is y - y1 = m(x - x1). You already have (x1, y1) to substitute in so do that and also substitute in your m.
