Answer:
20 miles.
Step-by-step explanation:
You're on the right track with your answer of 12. You added the sides you knew & multiplied by 2.
I'm picturing the park like a rectangle. So there are two sides that are 3 miles long, and 2 sides that are 2 miles long. For perimeter, we add all the sides.
3 + 3 + 2 + 2 = 10. And he walked the park twice, so 2 x 10 = 20
No, they are not congruent.

Answer: f(x) = x²
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: f(x) = a(x - h)² + k where;
- |a| is the vertical stretch
- -a is a reflection across the x-axis
- (h, k) is the vertex
The parent function is where a = 1 and the vertex is at the origin <em>(h, k) = (0, 0)</em>
→ f(x) = 1(x - 0)² + 0
⇒ f(x) = x²
Answer:
Step-by-step explanation:
(0, 1) (1, -1)
(-1 - 1)/(1 - 0) = -2/1 = -2
y - 1 = -2(x - 0)
y - 1 = -2x + 0
y = -2x + 1
