Hi here are the answers:)
Part A:
x = 3
Part B:
A = (3, 2)
Part C:
You can find the vertex by finding the mid-point of the focus and directrix. So the vertex is (-1, 2)
Part D:
The parabola opens left. This is because the parabola always opens toward the focus.
Part E:
The value of p is the distance from the focus to the vertex or the vertex to the directrix. To find p you can minus x-coordinate of focus with x-coordinate of the directrix, then divide it by 2. So this will be: -5-2/2 = -4
Part F:
p = -4
Part G:
Part H: image is attached down below. Fyi the C should be V (vertex)
Part I:
*I'm not really sure about this one*
Part J:
1. x = 1/4 (y-3)>2+3
2. x = 1/12 (y +1)>2 +5
*I'm not really sure about this one either srry:(*
Hope this helped bai bye.
Answer:
£1372
Step-by-step explanation
20% vat:
- 20% of 15,600 is 3120
- 3120+15,600= 18720
so if she paid a deposit of 5000 she would have a remaining amount of 13,720 in total
13720 divided by 10 equals 1372 so her 10 payments would be £1372
Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.
One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
This is your answer
-581472
the answer would be E because if you round answer E to 3mph and divide by 2 you get 1.5 and a hour is 60 minutes divide that by 2 and you get 30 minutes however you walked slightly slower so it would take 5 minutes longer.
