Answer:

Step-by-step explanation:

Comparing Point P and P' by getting any coordinate.

we will take x coordinate

P has x-coordinate 2 while P' has x-coordinate 8

To find the scale factor, we will divide them

=8/2 gives 4 so the scale factor is 4 this means that rectangle PQRS is dilated 4 times of its perimeter.

So,

Perimeter of P'Q'R'S'= 16 × 6 = 64

What is the vertex of a parabola having the equation y = –2(x – 5)2 + 7? Which direction does the parabola open?

Vika [28.1K]

$y = -2(x-5)^2 + 7$

That's vertex form for a parabola $y=a(x-p)^2+q$ and we read off vertex (p,q) as

Answer: Vertex (5,7)

The negative a tells us this is a downward opening parabola (upside down from the usual $y=x^2$ . I remember CUP - Concave Up Positive; here a is negative so not a cup, instead concave down. The same rule applies to second derivatives in calculus so memorize it now and use it later.
