Answer:
Step-by-step explanation:
Sin 21 = ![\frac{opposite side}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%20side%7D%7Bhypotenuse%7D)
Sin 21 = ![\frac{BC}{15}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7B15%7D)
0.3583 = ![\frac{BC}{15}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7B15%7D)
0.3583*15 = BC
BC = 5.3745 = 5.37 m
Tan ∅ = ![\frac{opposite side}{adjacent side}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%20side%7D%7Badjacent%20side%7D)
Tan ∅ = ![\frac{4}{5.37}= 0.7448](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5.37%7D%3D%200.7448)
∅ = tan⁻¹ (0.7448) = 36.67 = 36.7

Answer:
P = -2600/3 t + 25600/3
P = -8200/3
Step-by-step explanation:
t is the time in years since 1990, so two points on the line are (5, 4200) and (8, 1600).
Using the points to find the slope:
m = (y₂ − y₁) / (x₂ − x₁)
m = (1600 − 4200) / (8 − 5)
m = -2600/3
Now writing the equation in point-slope form:
P − 4200 = -2600/3 (t − 5)
Converting to slope-intercept form:
P − 4200 = -2600/3 t + 13000/3
P = -2600/3 t + 25600/3
In 2003, t = 13:
P = -2600/3 (13) + 25600/3
P = -8200/3
