8 0

Step-by-step explanation:

The following sequence is in AP

Suppose the first term is denoted by"a" and the common difference by"d"

a=3

d=4.5-3= 1.5

the nth term = a + (n-1)d

= 3+(n-1)1.5

=3+1.5n -1.5

=1.5+1.5n

The vertex of the graph of y = -4(x + 3)2 + 2 is ( , )

andrezito [222]

Answer:

Step-by-step explanation:

This quadratic is of the form

$y=-a(x-h)^2+k$ where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).
