Answer:
31/1488 --> 1/48
Step-by-step explanation:
1. let 31/1488=x^-1
2. 31*x^-1=1488
3. 31*48=1488
C (2,3)
All you have to do is substitute in the x and y values.
x=2 y=3
3=2+1 So that is correct.
Then -1/2 times 2+4=3! This is correct.
So the answer is C. Hope this helps, have a good day. c;
If you have a calculator use that and you should get the same answer.
The volume is equal to
step 1
Find the radius of the base of cylinder
we know that
The circumference of a circle is equal to
we have
assume
substitute and solve for r
step 2
Find the volume of the water tank (cylinder)
substitute
(-2, 1) and (6, 1)
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.
__
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.
