6.5^2 x 6.5^2= 1785.0625
Answer: 1785.1 sq units
Answer:
Vertex
Step-by-step explanation:
The minimum or maximum point of a quadratic function is called the vertex.
The equation of a quadratic function in the vertex form is
.
The coordinates of the vertex are V(h,k)
If 'a' is positive, then V(h,k) is a minimum point.
If 'a' is negative, then V(h,k) is a maximum point.
Answer:
B
Step-by-step explanation:
Answer: 300 percent
Step-by-step explanation:
Where: 15 is the old value and 60 is the new value. In this case we have a positive change (increase) of 300 percent because the new value is greater than the old value.
Answer:
y = ( x − 2 ) ^ 2 + 3
y = x^2 − 4x + 7
Step-by-step explanation:
y = a ( x − h ) ^ 2 + k
where vertex is (h,k) = (4,-1)
h=4, k=-1
y = a ( x − 4 ) ^ 2 - 1
sub ( 2,3 )
3 = a (2 - 4)^2 - 1
a=1
y = 1 ( x − 2 ) ^ 2 + 3
y = ( x^2 − 4x + 4 ) + 3
y = x^2 − 4x + 7
