N=0
because u have
4n-9=9

4*n-9(-9)=0
so it n=0

Type the missing number in this sequence: 1, 2, , 8, 16

Margaret [11]

All the numbers are multiplied by 2 or doubled.

So the missing number after 2 is 4.

After 16 is 32.

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

The junior class of Eastlake High School has 146 students, and 67 of them are girls. How many boys are there in the class?

Hello!

In order to find how many boys there are in the class simply subtract 67 from 146:

146-67= 79

There are 79 boys in the class

I hope it helps!
