Answer:

x^2-6x+y^2+4y=-4

Step-by-step explanation:

I am assuming you want the equation of the circle. We know that the equation of a circle is (x-h)^2 + (y-k)^2 =r^2, where r is the radius, and h and k are the x and y coordinates of the center respectively. We can solve for this by plugging in the numbers.

(x-3)^2+(y+2)^2=3^2

x^2-6x+9+y^2+4y+4=9

x^2-6x+y^2+4y=-4

How do you find the area of each regular polygon

Alex73 [517]

If the drawing of your octagon (or whatever) has been separated into triangles, and one triangle's area is labeled, then you do not need to know the apothem. Just take the area of that one triangle, and multiply by the number of sides in the original polygon.

1) h(x)=3x3 g(x)= - 4x+1 Find (h+g)(10)

Aleksandr-060686 [28]

Answer:

$(h+g)(10) = 2691$

Step-by-step explanation:

$h(x) = 3x^3\\g(x) = -4x+1$

Adding both equations will make it:

$(h+g)(x) = 3x^3-4x+1$

Putting x = 10 will make it:

$(h+g)(10) = 3(10)^3-4(10)+1$

= 3(1000)-40+1

= 3000-39

= 2961

The arc length

Zina [86]

Answer:

s = rθ
2.5 radians
143.24°

Step-by-step explanation:

The applicable formula is ...

s = rθ

where s is the arc length, r is the circle's radius, and θ is the central angle in radians.

Filling in the given values, we find ...

15 = 6θ

θ = 15/6 = 2.5 . . . radians

Pi (π) radians is 180°, so the angle in degrees is ...

2.5(180°/π) ≈ 143.24°
