Find the diameter of a circle whose equation is

Mathematics
1 answer:
Olin [163]3 years ago
7 0

Answer:

D) 20

Step-by-step explanation:

x^2 + (y - 2)^2=100

This can be rewritten as

(x-0)^2 + (y - 2)^2=10^2

This is in the form

(x-h)^2 + (y - k)^2=r^2

The radius is 10

The diameter is 2 times the radius

d = 2*r = 2*10 = 20

The coordinates of the 3 of the vértices of a parallelogram are (-7, 3), (-6, 1), and (-4, 5). What is the equation for the line
Natali [406]

We know, opposite sides are parallelogram is parallel, therefore slopes are equal.

Slope of line one :

m=\dfrac{-7-(-6)}{3-1}\\\\m =\dfrac{-1}{2}\\\\m= -0.5

So, equation of other line passing through (-4,5) and have slope of -0.5 is :

y-5 = -0.5( x-(-4))

y-5 = -0.5x - 2

y  + 1/2x = 3

2y + x = 6

Therefore, equation of line containing the (-4, 5) is 2y + x = 6.

Hence, this is the required solution.

Help w this plsss,!,!,, 20pointsss
Kay [80]

Answer:

Area = Length × width

16 = (3x +2 ) × ( x)

16 = 3x² +2x

3x² +2x -16=0

( 3x+8 ) ( x -2 ) =0

3x +8=0 —> 3x = – 8 —> x = – 8/3 —> x = – 2.6

x-2=0 —> x = 2

I hope I helped you^_^
