Answer:
9
Step-by-step explanation:
Let the equation of a parabola be
= 4ax.
Then , focal length of the parabola is a.
As , (0,0) is the vertex and its focus is (a,0)
Thus, focal length comes out to be a.
Here,
a is given as 9 units .
Thus focal length of the parabola, d, equals to 9 units
Answer:
=6x+20
Step-by-step explanation:
3(x+5)+(3x+5)
Solution:
=3x+15+3x+5
=6x+20
Supplementary angles add up to 180 degrees.
x + 107 = 180
x + 107 - 107 = 180 - 107
x = 73
The correct answer is B. 73 degrees.
Hope this helps =)
P = 25h + 600.
This is because even if he works no overtime, he still gets his 600.
