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)

6 to the third power divided by 4+2 x 9(32x8-17x4)

Elodia [21]

Answer:

3438.

Step-by-step explanation:

6³ ÷ 4 + 2 × 9 (32 × 8 - 17 × 4)

= 6³ ÷ 4 + 2 × 9 (256 - 68)

= 6³ ÷ 4 + 2 × 9 × 188

= 216 ÷ 4 + 2 × 9 × 188

= 54 + 2 × 9 × 188

= 54 + 3384

= 3438

3438 is the answer.

What is 1/8 divided by 5/7

SpyIntel [72]

It becomes 7/40. To get it, you have to put 1/8 times 5/7. Then, flip the second fraction, (5/7), so that it becomes 7/5. Multiply 1/8 and 7/5, to get 7/40. You call this "reciprocal".

CORRECT AND CLEAR ANSWER WILL BE GIVEN BRAINLIEST An object of mass 0.30 kg is thrown vertically upwards and reaches a height of

Natalka [10]

Answer:

Final potential energy = 24 Joule

The velocity with which object must be thrown = $4 \sqrt{10}$ m/s

Step-by-step explanation:

<u>Given:</u>

Mass of object, m = 0.30 Kg

Height of object, h = 8 m

Acceleration due to gravity, g = 10 $ms^{-2}$

a) Formula for Potential Energy:

$E_p =mgh$

Where m is the mass of object

g is acceleration due to gravity and

h is the height of object

Putting the values of m, g and h

$E_p = 0.3 \times 10 \times 8\\\Rightarrow E_p =24 J$

b) Formula for initial and final velocity:

$v^{2} =u^{2} +2gh$

where v is the final velocity

u is the initial velocity with which the object is thrown

g is acceleration due to gravity and

h is the height obtained by object

here v = 0 at the height 8 m because it will come to rest at the point it attains the maximum height.

h = 8m

g = -10 $ms^{-2}$ (negative because the object's velocity is decreasing)

Putting the values to find 'u':

$0^{2} =u^{2} +2 \times -10 \times 8\\\Rightarrow u^{2} = 160\\\Rightarrow u = 4 \sqrt{10}\ m/s$
