4x^{2}+16y^{2}-24x+64y+36=0<br> The center is:<br> The vertices are:<br> The foci are:

gulaghasi [49]

For the given equation,4x²−y²−24x−4y+28=0.The center is (h,k)=(3,−2), vertex (h+a,k)=(4,−2) and (h−a,k)=(2,−2), foci is (h+c,k)=(5.23,−2) and (h−c,k)=(0.77,−2)

<h3>What is the equation?</h3>

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, the equation of the hyperbola is,

4x²−y²−24x−4y+28=0

Comparing the equation with the standard equation we get,

Center (h,k)=(3,−2)

Vertex (h+a,k)=(4,−2) and (h−a,k)=(2,−2)

Foci (h+c,k)=(5.23,−2) and (h−c,k)=(0.77,−2)

Asymptotes y=2x−8 and y=−2x+4

Thus, for the given equation,4x²−y²−24x−4y+28=0.The center is (h,k)=(3,−2), vertex (h+a,k)=(4,−2) and (h−a,k)=(2,−2), foci is (h+c,k)=(5.23,−2) and (h−c,k)=(0.77,−2)

(5)/(9,) (5)/(3,) 5,15,45 are these numbers a sequence of geometric numbers

Ad libitum [116K]

<u>Answer:</u>

It is a sequence of geometric numbers.

<u>Step-by-step explanation:</u>

A sequence or series of numbers where each term after the first term is found by multiplying it with a fixed or certain number is called a geometric sequence or geometric progression.

We can check whether the given series is geometric or not by dividing each term by its previous term to see if their common ratio is the same.

$\frac{45}{15}=3$

$\frac{15}{5} =3$

$\frac{5}{\frac{5}{3} } =3$

$\frac{\frac{5}{3} }{\frac{5}{9} } =3$

Since the common ratio is the same, therefore it is a sequence of geometric numbers.
