Answer:
a (3,-1)
Step-by-step explanation:
The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...
f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1
f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form
Comparing this to the generic vertex form ...
f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)
we see that h=3 and k=-1.
The vertex is (h, k) = (3, -1).
Answer:
The value of k that makes the relationship shown in the table below proportional is
Step-by-step explanation:
The relation is proportional if
Putting values of x and y to find k.
For x =2 and y =1 k is:
For x =4 and y =2 k is:
For x =6 and y = 3 k is:
For x = 8 and y = 4 k is:
For x =10 and y = 5 k is:
So, The value of k that makes the relationship shown in the table below proportional is
Answer:
14.25 units
Step-by-step explanation:
Area of a square=
Solving the equation using quadratic equation then as attached
x=14.25 units
To prove
x-3=14.25-3= 11.25 units
area=11.25*11.25=126.5625 sq units
