Answer:
(0, -3)
Step-by-step explanation:
The vertex is halfway between the directrix and the focus. The vertex is at (0, 0) and the directrix is a (0, 3). There are 3 units between them, so that means that the focus is 3 units the other way at (0, -3).
Answer:
y=√x+5 -1
the answer is option C,,
x=-7,y=√-7+5 -1=√-2 -1
we can't find the square root of negative values, therefore it displays as error
x=-6,y=√-6+5-1=√-1 -1
same reason
x=-5,y=√-5+5-1=√0-1=-1
x=-4,y=√-4+5-1=√1-1=0
x=-1,y=√-1+5-1=√4-1=1
x=4,y=√4+5-1=√9-1=2
Answer:

Step-by-step explanation:
<u>Step 1</u>:-
Suppose that E and F are two events and that P(E n F) = 0.3
also given P(E) =0.5
<u>Conditional probability</u>:-
if E₁ and E₂ are two events in a Sample S and P(E₁)≠ 0, then the probability of E₂ , after the event E₁ has occurred, is called the <u>Conditional probability</u>
of the event E₂ given E₁ and is denoted by


If this is just an expression, then all you have to do is combine like terms, or groups of numbers and variables that have the same variable.
When simplified, you get the equation
-12+ 16r or
-18+6+3r+13r=16r-12
Okay, then ask an answer!
