Which value of p makes the equation 18+ 2 (3p – 8) = –37 true?

Volgvan

Answer:

p = -6.5

Step-by-step explanation:

<u>Given:</u>

18+ 2 (3p – 8) = –37

<u>Solving for p:</u>

18+ 2 (3p – 8) = –37
18 + 6p - 16 = -37
6p + 2 = -37
6p = -37 - 2
6p = -39
p = -39/6
p = -6.5

Does the point (-4, 2) lie inside or outside or on the circle x^2 + y^2 = 25?

d1i1m1o1n [39]

Given equation of the Circle is ,

$\sf\implies x^2 + y^2 = 25$

And we need to tell that whether the point (-4,2) lies inside or outside the circle. On converting the equation into Standard form and determinimg the centre of the circle as ,

$\sf\implies (x-0)^2 +( y-0)^2 = 5 ^2$

Here we can say that ,

• Radius = 5 units

• Centre = (0,0)

Finding distance between the two points :-

$\sf\implies Distance = \sqrt{ (0+4)^2+(2-0)^2} \\\\\sf\implies Distance = \sqrt{ 16 + 4 } \\\\\sf\implies Distance =\sqrt{20}\\\\\sf\implies\red{ Distance = 4.47 }$
