The answer is the square root of 23 i.
(The “i” is outside of the square root symbol, and the 23 is positive).
Hope this helps! (:
Answer:
Step-by-step explanation:
If 60% failed then 40% passed
.4n=500
n=1250 so there are 1250 candidates of which
.6(1250)=750 failed
So 750 candidates failed.

Answer:
number of correct answers by the total number of questions
Step-by-step explanation:
The first step in the process is to express the score as a fraction. That has already been done here, but apparently, we're to say what that fraction is.
The required fraction that must be found as a first step is found by dividing the ...

Answer:
the vertex is at (2, 5) and the axis of symmetry is x = 2
Step-by-step explanation:
A word to the wise: Please use " ^ " to indicate exponentiation. And so we have:
y= -2x^2+8x-3
The x-coordinate of the vertex and the equation of the axis of symmetry is determined by the equation
b -8
x = ------- which here is x = ----------- = 2
2a 2(-2)
Then the y-coordinate of the vertex is f(2) = -2(-2)^2 + 8(2) - 3 = 8 - 3 = 5
and so the vertex is at (2, 5) and the axis of symmetry is x = 2
