Answer:

p = 4

Step-by-step explanation:

Given equation:

$x^2+(p-3)y^2-4x+6y-16=0$

<u>Standard equation of a circle:</u>

$(x-a)^2+(y-b)^2=r^2$

(where $(a,b)$ is the centre of the circle, and $r$ is the radius)

If you expand this equation, you will see that the coefficient of $y^2$ is always one.

Therefore, $p-3=1$

$\implies p=1+3=4$

<u>Additional information</u>

To rewrite the given equation in the standard form:

$\implies x^2+y^2-4x+6y-16=0$

$\implies x^2-4x+y^2+6y=16$

$\implies (x-2)^2-4+(y+3)^2-9=16$

$\implies (x-2)^2+(y+3)^2=16+4+9$

$\implies (x-2)^2+(y+3)^2=29$

So this is a circle with centre (2, -3) and radius √29

Answer:

Step-by-step explanation:

well the anser has to equal 9 if you solved the question correctly BUT the other questions have to equal 9 so the first one is like this

(3*2-2)+(5*2+5*-1)

= (6-2)+(5*2+5*-1)

= (4)+(5*2+5*-1)

= 4+(5*2+5*-1)

= 4+(10+5*-1)

= 4+(10+-5)

= 4+(10-5)

= 4+(5)

= 4+5

= 9

Now the answers A is not it because

8*2+5*-3

= 16+5*-3

= 16+-15

= 16-15

= 1

B isnt it because

8*2+5*-1

= 16+5*-1

= 16+-5

= 16-5

= 11

And C isnt it because

2*2+5*-3

= 4+5*-3

= 4+-15

= 4-15

= -11

So that leaves D and this is how it is correct

= 8*2+7*-1

= 16+7*-1

= 16+-7

= 16-7

= 9

Hope this helps! Sorry I took so long

Answer:

2 seconds
72 feet

Step-by-step explanation:

The usual equation used for the vertical component of ballistic motion is ...

h(t) = -16t² +v₀t +h₀

where v₀ is the initial upward velocity, and h₀ is the initial height. Units of distance are feet, and units of time are seconds.

Your problem statement gives ...

v₀ = 64 ft/s

h₀ = 8 ft

so the equation of height is ...

h(t) = -16t² +64t +8

For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Then the axis of symmetry of the height equation is ...

t = -64/(2(-16)) = 2

The object will reach its maximum height after 2 seconds.

The height at that time will be ...

h(2) = -16(2²) +64(2) +8 = 72

The maximum height will be 72 feet.
