Answer:
Option D
Step-by-step explanation:
Formula to be used,
Scale factor =
By this formula,
L =
= 77 inches
Similarly, width of the the dilated rectangle =
= 35 inches
Perimeter of the new rectangle = 2(Length + width)
= 2(77 + 35)
= 224 inches
Option (D) will be the correct option.
Answer:
Vertex (2 , -25)
Axis of symmetry: x = 2
Step-by-step explanation:
<h3>Vertex of parabola:</h3>The vertex is the highest point if the parabola open downwards and the lowest point if the parabola opens upward.
f(x) = (x - 2)² - 25
The given quadratic function is in vertex form.
f(x) = a(x - h)² + k
Here, (h , k) is the vertex of the parabola.
h = 2 ; k = -25
The axis of symmetry is the vertical line that divides the parabola into two equal halves and it passes through the vertex of the parabola.
Axis of symmetry: x = h
