Answer:
1 (-4,5), (-2,1) (2,2) (5,5)
2 (0,1) (-4,3) (-4,1)
Step-by-step explanation:
A definition of a common ration Is the number multiplied must be the same for each term in the sequence. The common ratio is the amount between each number in a geometric sequence. To determine the common ration you can just divide each number from the number preceding it in the sequence. Here is an example I found of a common ration to further help you
2,4,8,16
16/8=2 you would then continue to divide to ensure that the pattern is the same for each number
8/4=2
4/2=2 the ratio is the same for each one so the common ration would be 2 I hope this helps could I please get a brainliest :)
Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.
Answer:
4
Step-by-step explanation:
Answer:
b) (1,-7)
Step-by-step explanation:
the x changes by 4 so subtract the midpoint x by 4 to get x=1
then the y stays the same y= -7
