Quadrilateral ABCD is a rhombus. What conditions must be true?
belka [17]

Answer: B, C, D

Step-by-step explanation:

  1. A <u>rectangle</u> must have at least one right angle, not a rhombus. So, A is wrong.
  2. This is a specific property of a rhombus, so B is correct.
  3. This is a specific property of a rhombus, so C is correct.
  4. Since all rhombi are parallelograms, and diagonals of a parallelogram bisect each other, D is also correct.

(x-6)^2+(y+5)^2=212 what is the center of the circle?
madam [21]
The circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". 
Therefore the center is: (6,-5)

On a coordinate plane, a curved line crosses the x-axis at (negative 1.5, 0), the y-axis at (0, negative 2), and the x-axis at (
Lisa [10]

Domain F(x) = All real numbers and the Range F(x)  [ -2 ,  + ∞ ]

<h3>What is the domain and range of a function?</h3>

A domain is the set of values for which the given function is defined.

Range is the set of all values which the given function can output.

The curve points are

P₁ ( -1,5 , 0 )   Q ( 0. -2 ) and P₂ ( 1,5 , 0 )

We can see that P₁  and P₂ are symmetric around the y-axis, and point Q looks like a vertex so we can conclude the curve as

ax² + bx + c = y

The curve is a parabola

when x = 0      

y = -2    

then   c  = - 2

The equations we get,

a (-1.5)²  +  b (-1.5) + c = 0      

2.25a  - 1.5b - 2 = 0

a (1.5)²   +  b ( 1.5)  + c = 0    

2.25a + 1.5b -2 = 0

Adding these two equations

4.5a - 4 = 0

a =  4/4.5

The vertex is Q ( 0 , -2 )

x = - b/2a      

0 = - b/ 9      

b  =  0

Therefore the equation of the function :

ax² + c = 0

(4/4.5) x² - 2 = 0

Therefore, Domain F(x) = All real numbers and the Range F(x)  [ -2 ,  + ∞ ]
