Acute: anything less than 90 but greater than 0
so, m<CAD
right: angles at exactly 90 degrees, so m<AEC,
and obtuse angles are anything greater than 90 but less than 180 degrees,
so CDA (you can tell by the picture that it is bigger than 90- 90 degrees is exactly perpendicular)
Answer:
n = -2
Step-by-step explanation:
Eliminating parentheses, you have ...
2n +6 -6n = 14
Combining terms and subtracting 6, you get ...
-4n = 8
Dividing by the coefficient of n gives ...
n = -2

<em><u>Check</u></em>
2(-2) +3(2 -2(-2)) = 14
-4 +3(2+4) = 14
-4 +3(6) = 14
-4 +18 = 14 . . . . answer checks OK

Answer:
726 rpm
Step-by-step explanation:
The angular speed is not dependent upon the radius. The rotational speed is 726 rpm at any radius.
Answer:
f(g(x)) = g(f(x)) = x and f and g are the inverses of each other.
Step-by-step explanation:
Here, the given functions are:
To Show: f (g(x)) = g (f (x))
(1) f (g(x))
Here, by the composite function:
⇒ f (g(x)) = x
(2) g (f(x))
Here, by the composite function:
⇒ g (f(x)) = x
Hence, f(g(x)) = g(f(x)) = x
⇒ f and g are the inverses of each other.
