Answer:
Hollow-circle rightward-facing arrow with start point number 1.
Step-by-step explanation:
x/8 > 2/(3 + 2^2 + 1) * 2
Multiply both sides by 2:
x/4 > 2/(3 + 2^2 + 1)
Resolve bracket:
x/4 > 2/(3 + 4 + 1)
x/4 > 2/8
x/4 > 1/4
Multiply both sides by 4:
x > 1
To graph this on the number line, you must draw an arrow facing to the right starting from the number 1. It is important that the circle with the arrow is hollow - this is because a hollow circles means more/less than, whereas a filled circled means more/less than or equal to, and this inequality is only more than, not more than or equal to.

Answer:
D
Step-by-step explanation:
Given that
f(x)=-2x – 1
g(x) = -1/2x+1/2
I The function f( g(x)) = x for all real x.
-2(-1/2X + 1/2) - 1
X - 1 - 1
X - 2
II. The function glAx)) = x for all real x.
- 1/2( -2X - 1 ) + 1/2
X + 1/2 + 1/2
X + 1
III. Functions fand g are inverse functions
Inverse of f(x)
Y = -2x - 1
X = - 2Y - 1
- 2Y = X + 1
Y = - 1/2X - 1/2
Therefore, none of the above answers is correct.
The correct answer is therefore D
The answer is 33 meters
use the Pythagorean theorem
56^2+x^2=65^2
3136+x^2=4225
x^2=1089
x=33
