A circle
That's a very easy one cuz if u try u will find it to be correct
Answer:
(-2, 1) and (6, 1)
Step-by-step explanation:
The standard form equations for a hyperbola are ...

The first form opens horizontally; the second opens vertically. Further, the center-focus distance 'c' is given by ...

The attached figure illustrates the relation between the various parameters and the features of the hyperbola.
__
<h3>7.</h3>
Using the above information and the information in the first attachment, we find ...
(h, k) = (2, 1)
a = 4, b = 2
The vertices are (h±a, k), so are (2±4, 1) = (-2, 1) and (6, 1).
__
The second attachment illustrates the hyperbola and its vertices.
There are 10 possible results _:- 1 through 10
possible choices for odd or multiple of 5 are 1,3,5,7,9,10 - 6 numbers
so required probability = 6/10 = 3/5
Answer:
<h3>9.9s</h3>
Step-by-step explanation:
First note that the river is on the ground level. The height of the river at the ground level is 0
Given the the height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+1552
When h = 0
0 = -16t^2+1552
16t^2 = 1552
t² = 1552/16
t² = 97
t = √97
<em>t = 9.9secs</em>
<em>Hence the time it takes is 9.9secs to the nearest tenth</em>
