Y = -(1/2)(x-2)² +8
Re write it in standard form:
(y-8) = -1/2(x-2)² ↔ (y-k) = a(x-h)²
This parabola open downward (a = -1/2 <0), with a maximum shown in vertex
The vertex is (h , k) → Vertex(2 , 8)
focus(h, k +c )
a = 1/4c → -1/2 = 1/4c → c = -1/2, hence focus(2, 8-1/2) →focus(2,15/2)
Latus rectum: y-value = 15/2
Replace in the equation y with 15/2→→15/2 = -1/2(x-2)² + 8
Or -1/2(x-2)² +8 -15/2 = 0
Solving this quadratic equation gives x' = 3 and x" = 2, then
Latus rectum = 5
Answer:
Ermmm, theres no table/graph so maybe try repostin?
Step-by-step explanation:
This is experimental probability, since it is based on the outcome of an experiment.
Its hourly rate of Jillian is 12 hours.
Here we have to find the hourly rate.
Let h be the hourly rate. As it is given that overtime is a time and a half rate.
So the overtime hour is 1.5h.
The total amount Jillian get is $516.
So from this, we get an equation:
40h + 2(1.5h) = 516
40h + 3h = 516
43h = 516
h = 12
Therefore we get the hourly rate as 12.
