Answer:
f(x)=8-4
Step-by-step explanation:
f(x) = 8 (x+1/4)^2-1/2
f(x) = 8 – (x+1/4)^2-1/16
f(x) = 8 – 2
f(x) = 8 – 4
The complete question in the attached figure
we know that
triangle OBR is a right triangle
so
<span>applying the Pythagorean theorem
</span>OB²=OR²+RB²----> OB²=3²+4²-----> 25
OB=√25-----> OB=5 units
the answer is OB=5 units
Answer:
a
Step-by-step explanation:
Linear Pair Angles are always congruent because you can see that the parallel lines are cut by a transversal, which creates special angle pairs. The angles would be Alternate Exterior Angles; angles on opposite sides of a transversal but outside the two parallel lines form supplementary angle pairs. The angles also are Corresponding Angles.
