Answer:  A) 2

Step-by-step explanation:

The shape has been enlarge which means B and D are  ruled out because if a shape gets enlarge its scale factor has to be greater than 1.

We will use the coordinate of the image of D  to find the scale factor.

Pre-image:  (2,2)   Enlarge or image: (4,4)    

So as we can see to get from 2 to 4 you will have to multiply by 2. So the scale factor is  2

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
12345 [234]

Answer:

14.76 cm

Step-by-step explanation:

Use the pythagorean theorem:

a² + b² = c²

Plug in the side lengths and solve for c:

7² + 13² = c²

49 + 169 = c²

218 = c²

14.76 = c

So, the hypotenuse is approximately 14.76 cm

Select the correct answer. Segment KL is a diameter of circle Q. Circle Q is represented by the equation (x − 11)2 + (y + 15)2 =
m_a_m_a [10]

Answer:

2√7

Step-by-step explanation:

Mathematically, the equation of a circle can be represented by;

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

where (h,k) = center and r = radius

Applying this to the question, we can see that the length of the radius of the circle is √7

The diameter is always twice the radius

Thus, the diameter KL = 2 * √7 = 2√7
