Tbh I don’t know and I hope someone gives you the answer
Answer:
<h2>
The domain=3</h2>
Step-by-step explanation:
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:
If Lawrence has 24 beads and divided them into 4 groups you want to see how many he put into each group first
To do this we are going to take 24/4=6
Each group has 6 in it
If he gave one group to his sister, than he gave 6 beads to his sister
Now we want to take 6 away from 24 to find out how many he has left
24-6=18
He now has 18 beads
Hope this helps ;)
