Problem 9

h(1/8) = 3(1/8) + 1/4
h(1/8) = 3/8 + 2/8
h(1/8) = 5/8

Problem 10

Q(k) = k - 3 / 2
-4 = k - 3 / 2
-8 = k - 3
k = -8 + 3
k = -5

Answer:

56.714°

Step-by-step explanation:

Since we do not have a full angle of this proposed triangle, we must do this by splitting it into two right triangles instead of using the law of sines.

250m*sin(40°) = 250m*0.64278760968 = 160.696902422m

452.4m-160.696902422m=291.703097578m

Use pythagorean theorem:

$\sqrt{250^2 - 160.696902422^2}$

62500-25823.494448025787=36676.505552

$\sqrt{36676.505551974216}$ = 191.511110779m

arctan(291.703097578m/191.511110779m)≈56.714°
