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
Answer: 87, 88, 89, 91, 92, 93, 94, 95, 96, 97, 98
Step-by-step explanation:
You basically try a whole bunch of numbers by taking those two numbers and another then adding them and dividing them by 3.
Answer:
Step-by-step explanation:
Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.
Therefore, we have:
To find the probability of two independent events, multiply the probability of the first event by the probability of the second event
Answer:
Step-by-step explanation:
if the given figure is triangle, then the required length can be calculated:
additional info: sin45°=1/√2.
