Answer:
the inverse is 9x + 18
Step-by-step explanation:
switch 'x' with 'y'
y = 1/9x - 2
x = 1/9y - 2
solve for y now, start with multiplying each side by 9
9x = y - 18
y = 9x + 18
f^-1(x) = 9x + 18
Answer:
220°
Step-by-step explanation:
The bearing of B from A is
180° + 40° = 220°
Answer:
BC = 205.8 feet
Step-by-step explanation:
Please see attached photo
From the attached photo:
Angle B = 71°
Adjacent = BD = 67 feet
Hypothenus = BC = x
The value of x can be obtained as follow:
Cos B = Adjacent / Hypothenus
Cos 71 = 67 / x
0.3256 = 67 / x
Cross multiply
0.3256 × x = 67
Divide both side by 0.3256
x = 67 / 0.3256
x = 205.8 feet
Therefore BC = 205.8 feet
