Answer:
It would be the first one or second one
Step-by-step explanation:
the answer is up ahead
Yay
so
this is going to be
(x-h)^2=4p(y-k)
(h,k) is the vertex
p is the distance from the vertex to the focus and the vertex to directix
half of the distance between directix and focus is p
if the directix is above the focus, p is negative
if the directix is below the focus, p is positive
so
we see
y=15/8 is the directix
focus is above directix (p is positive)
it is 2/8 or 1/4 above it
so
half of 1/4 is 1/8
p=1/8
the vertex is 1/8 below vertex so it is it at (-4,16/8) or (-4,2)
the equation is
(x-(-4))^2=4(1/8)(y-2) or
(x+4)^2=4(1/8)(y-2) is the equation
Answer:
The mean baseball score is 2.5
OK so each block is 3cm tall and 3.5cm wide (because 2 are 7cm wide)
so to measure the perimeter count all the side values for example:
the 5 squares at the bottom which measure 3.5cm each adds up to a total of 17.5cm then if you add the top 2 flat sides that's another 2, 3.5cm which adds up to 7cm. 17.5cm + 7cm = 24.5cm then their are 3 walls on each side measuring 3cm each so 3cm * 6 = 18
24.5cm + 18cm = 42.5cm (I think this is correct)
18m^3 + 2m^2 -1m hope this helped
