How to find equation hyperbola with asymptotes, center and transverse?
lapo4ka [179]
The equation for a hyperbola is (x-h)/a - (y-k)/b = 1
Or (y-k)/a - (x-h)/b = 1
h represents the x value of the coordinate
k value represents the y value of the coordinate 
together they represent a point, which is the center
So (h,k) is (x,y)

The asymptote is y-k = +/- b/a (x-h)
The transverse is the line that goes through the hyperbola.

Nattalie picked 135 berries in 15 minutes at this rate how long will it take her to pick 486 berries
forsale [732]
Well, If she takes 15 minutes to pick 135 berries, 30 minutes total would be 270 berries, so if you take another 15 minutes picking berries it would be a total of 405 berries but you still need 81 more. so if she can pick 405 in 45 minutes, it would be around a hour and something. 

Hope I helped or at least made you think about it

Answer:

72 square inches.

Step-by-step explanation:

Convert feet and inches.

36 feet = 36*12  inches

                          =432 inches

Width of the floor; Converted from feet to inches:

32 feet = 32*12  inches

                          = 384 inches

Calculate how many times the length (l) has been scaled down.

432 inches of length has been reduced to 9 inches.

\frac{432}{9}=48

Now the length has been scaled down 48 times.

Scale down the width (w) 48 times.

\frac{384}{48} =8

The width of the scale drawing = 8 in

Area of the Scale drawing = Scaled down length * Scaled down width

                                        =9*8                                            =72in^{2}
