Answer:
(g o f)(x) =
(not simplified)
Step-by-step explanation:
(g o f)(x) = g(f(x))
g(x) =
f(x) = 
g(f(-5)) = g(
=
= 
g(-170) =
= 
we don't know what the value of "X" is, so therefore, we cannot conclude that it is 15 cm.
Answer:
1
Step-by-step explanation:
(1/2)(2/1)=2/2=1
Answer:
1/2
Step-by-step explanation:
cotangent is the reciprocal of a tangent
tanθ = 2
cotθ = 1/2
If K is midpoint of JL then JK = 0.5JL
JL = 4x - 2; JK = 7
The equation:
0.5(4x - 2) = 7
2x - 1 = 7 |add 1 to both sides
2x = 8 |divide both sides by 2
<u>x = 4</u>
<u>JL</u> = 4(4) - 2 = 16 - 2 = <u>14</u>
<u>KL</u> = JK =<u> 7</u>
