d.Adjacent sides are congruent

In a kite, there is always an angle that is not right, otherwise, it would have a rectangular shape.

The diagonals are not of the same length because that would mean it would have a rectangular shape as well.

The sides are not equal, because that would mean it would have a rhomboid shape, to which a square belongs to.

The top edges are congruent with each other, as well as the bottom ones. This is because you can turn one into the other by reflecting them using an isometry, so D is true.

If a varies inversely as the cube root of b and a=1 when b=64, find b​
Mrrafil [7]

Answer:

  b = 64/a³

Step-by-step explanation:

Using the given information, we can only find a relation between a and b. We cannot find any specific value for b.

Since a varies inversely as the cube root of b, we have ...

  a = k/∛b

Multiplying by ∛b lets us find the value of k:

  k = a·∛b = 1·∛64 = 4

Taking the cube of this equation gives ...

  64 = a³b

  b = 64/a³ . . . . . divide by a³

The value of b is ...

  b = 64/a³

Find the standard equation of the circle having the given center (6,-2) and radius 1/5.
Ivenika [448]
The equation of a circle is (x-h)²+(y-k)²=r², with h being the x value in the center, k being the y value, and r being the radius. Plugging them in, we get 
(x-6)²+(y-(-2))²=(1/5)²
                       =  1/25
                       = (x-6)²+(y+2)²

A quadratic function y=f(x)y=f(x) is plotted on a graph and the vertex of the resulting parabola is (3, -6)(3,−6). What is the v
sergey [27]
<h3>Answer:   (3,-4)</h3>

Explanation:

The vertex of f(x) is (3,-6)

The vertex of g(x) is (3,-4). We keep the x coordinate the same, but add 2 to the y coordinate. This shifts the vertex 2 units up.
