Answer: 1. What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
2.The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle.
Step-by-step explanation:
The answer would be 92 for both.
Explanation: the ) like marking in both symbolizes that both
Answer:
3.333 if the equation is: 
Step-by-step explanation:
Looks like you are saying those are base logarithms.
I think you have the equation:
Use product rule, that is, 
.
Both sides are the same except the insides. If we want the left hand side to be the same as the right hand side, then we need 3a and 10 to be the same.
When are those the same?
Set them equal and find out!
3a=10
Divide boht sides by 3:
a=10/3
Perform the division in your calculator:
10 division sign 3
gives you 3.333333333(repeating).
Answer:
Quadratic
