1.BD=AC
AC^2=(9^2)+(6^2)-2(9)(6)COS115
AC^2=117-108COS115
AC=√71.358
AC=8.447//
9.81 or 98.1 pretty sure it's the first one
Answer:
y = -3x - 4
Step-by-step explanation:
y = mx + b
-10 = -3 (2) + b
-10 = -6 + b
b = -4
Answer:
distance down wind
d - 6 = distance back
time = distance ÷ speed
x = d/20
x = (d - 6)/(16)
so d/20 = (d - 6)/16. Cross multiply
20d - 120 = 16d
-120 = -4d
30 = d so the whole trip assuming the bird gets back to the starting point is 60 miles
