Answer:
rules of exponents apply
Step-by-step explanation:
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)(a^c) = a^(b+c)
__
Applying those rules to the given equation, you get ...
Answer:
Step-by-step explanation:
Use the distance formula between points to find all sides:
AB=
BC=
CA=
This is a 45° 45° 90° triangle, where two of the sides are equal and the other side is the first two sides times , so yes, it is a right triangle.
Answer:
<u>The function f(x)=a(x-h)² + k is the parabola with vertex:</u>
- (h, k)
If the vertex is in the second quadrant, the h < 0 and k > 0
It can open up or down, so a ≠0, it opens up if a > 0, opens down if a < 0
The axis of symmetry is the line parallel to y-axis and passing through the vertex, so it would be the line:
- x = h
<u>Now let's assume h = -5, k = 2, a = 1, then our function is:</u>
- f(x) = (x + 5)² + 2
The graph is attached and it opens up as a = 1 > 0
<u>The line of symmetry is </u>
- x = - 5
