We see it is the y terms squared so it opens left or right
in form
(y-k)^2=4(p)(x-h)
vertex is (h,k)
and p is distance from focus to vertex, also distance from vertex to directix
if p>0, then it opens to the right and dirextix is to the left of vertex
if p<0, then it opens to the left and directix is tothe right of vertex
so
(y-1)^2=4(4)(x-(-3))
vertex is (-3,1)
4>0 so dirextix is to left of vertex
left is in x direction
-3-4=-7
directix is x=-7
IF i did my math correct it should be the 2nd answer b
<u>Answer:
</u>
The car’s rate in kilometer per minute is 1.2 kilometer/minute and in 20 min it can travel 24 kilometer
<u>Solution:
</u>
It is given that it can travel 72 kilometer per hour.
We know 1 hour = 60 min
So, the car travels in
60 min = 72 hour

Thus the cars rate in kilometer per minute is
is 1.2 kilometer per minute.
Now we know in 1 minute the car can travel 1.2 kilometer.
Therefore in 20 minutes it will travel 1.2
20 kilometers= 24 kilometers
PEMDAS
you would do left to right and look for multiplication or division.
64/2= 31
31*16=512
