What is the equation of the parabola in vertex form. Vertex(4,4),point(2,-4)
1 answer:
Answer:
y = -2(x - 4)^2 + 4.
Step-by-step explanation:
Vertex form:
y = a(x - 4)^2 + 4 (because the vertex is at (4, 4)).
To find the value of a we substitute the point (2, -4):
-4 = a(2-4)^2 + 4
4a = -8
a = -2.

Answer:
2100 second
Step-by-step explanation:
4:30 pm to minutes
4 × 60 + 30 = 240 + 30
= 270 minutes
5:05 to minutes
5 × 60 + 5 = 300 + 5
= 305
4:30 to 5:05
305 - 270
= 35 minutes
35 minutes to second
35 × 60
= 2100 second
He multiplied rather than dividing.

Y = mx + c therefore
m = 1
c = -2
