PLEASE HELP OMG the side lengths of triangle MNO are given: MN=5, NO=4, OM=2.5. the triangle is dilated by a scale factor of k w
1 answer:
The value of the scale factor k, is 1.5
<h3>Perimeter</h3>The perimeter of a shape is the sum of the side lengths of the shape
<h3>Dimensions </h3>The dimensions of the triangle MNO are given as:
Calculate the perimeter of the triangle as follows:
Divide 17.25 by 11.5 to calculate the scale factor (k)
Hence, the scale factor is 1.5

The vertex-form equation is
y = a(x+1)² -16
Putting in the y-intercept values, we have
-15 = a(0+1)² -16
1 = a . . . . . . . . . . . add 16
Then the x-intercepts can be found where y=0.
0 = (x+1)² -16
16 = (x+1)²
±4 = x+1
x = -1 ± 4 = {-5, 3}
y = a(x+1)² -16
