Information : The given hyperbola is a horizontal hylerbola with its centre (3 , -5) and one of its focus at (9 , -5) and vertex at (7 , -5) and as we can see that the focus and vertex have same y - coordinates, it must have its Transverse axis on line y = - 5.
Now,
it's vertex is given, I.e (7 , -5)
so, length of semi transverse axis will be equal to distance of vertex from centre, i.e
Now, it's focus can be represented as ;

so,
and we know, a = 4



Now, let's find the measure of semi - conjugate axis (b)






So, it's time to write the equation of hyperbola, as we already have the values of a and b ~

[ plug in the values, and h = x - coordinate of centre, and k = y - coordinate of centre ]

Answer:
The correct option is A) 13 to 3.
Step-by-step explanation:
Consider the provided information.
The pet store had 6 puppies selling for $104 each and 12 kittens selling for $24 each. Today, only 2 puppies and 8 kittens were left.
6-2 = 4 puppies sale
12-8 = 4 kittens sale
The cost of each puppies is $104.
Cost of 4 puppies:
4×$104=$416
The cost of each kittens is $24.
Cost of 4 kittens :
4×$24=$96
The ratio of sales of puppies to kittens is:


Hence, the ration of sales of puppies to kittens is 13/3.
Thus, the correct option is A) 13 to 3.
<h2>
Answer:</h2><h2>
The city population last year = 2233 approximately</h2>
Step-by-step explanation:
The current population of the city = 245,600
Rate of increase = 110 %
The population in previous year = ?
Let x be the population of previous year
x(110%) = 245600
x = 
= 2232.7
The city population last year = 2233 approximately
