<u><em>Step-by-step explanation:</em></u>
- Since the triangle is right use the tangent ratio to solve for x
- Multiply both sides by
x × 
( divide both sides by 
)
x = ≈ ( nearest tenth )
Answer:
Not a function.
Step-by-step explanation:
There must only be one output per input but here we see the input 18 has two outputs ; 3 and 15 therefore this is not a function.
B
The equation of a line in ' point- slope form ' is
y - b = m( x - a )
where m is the slope and (a, b ) a point on the line
here m = 
and (a, b ) = (3, 2 )
y - 2 = ( x - 3 ) → in point- slope form

<span>For </span>arc cos<span> x, the </span>dy/dx is equal to -1/ square root of (1 - x2).
<span>In this case, we still have 1/2 x inside the angle quantity so we multiply the </span>dy/dx above with 1/2. Hence, y' = is -1<span>/ 2 square root of (1 - x2); x = 1, y' is infinity. this means the line is horizontal. The answer hence is y = 1.</span>
