Parabola form : (y-k) = a(x-h)², where h and k are the vertex(h , k)
The vertex is given (2 , - 9), the equation of the parabola becomes:
y+9 = a(x-2)²
But we know this curve passes through (5, - 18)
Plug the respective values of x & y in the equation:
-18 +9 = a(5-2)² → - 9 = 9a & a = -9/9 and a= - 1
Answer:
It should be B- an=3n+1 because it seems to be adding one every time
Step-by-step explanation:
If the decimal is 1 number divide that number into 10 Then simplify the fraction if possible. if the decimal are 2 numbers divide those 2 numbers by 100 Then simplify the fraction if possible
3 numbers:by 1000, etc
Ex 0.4= 4/10 = 2/5
B = 4
A line with a slope of zero is a perfectly horizontal line, which means the y value (the second value) stays the same for every single point on the line.
So, if y equals 4 in the first point, then y still equals 4 in the second point, which means b is equal to 4.
