Answer:
8
Step-by-step explanation:
f(x)=3x^2-18x+10
a = 3, b = -18 and c = 10
The vertex of a parabola is in form a(x+d)^2 + e
d = b/2a = -18/2(3) = -18/6 = -3
e = c-b^2/4a = 10 - -18^2/4(3) = 10-27 = -17
Now the vertex form of the parabola becomes 3(x-3)^2 -17
Use the vertex form of the parabola in the vertex form of y = a(x-h)^2 +k
Where a = 3, h = -3 and k = -17
Now you have y = 3(x-(-3))^2 +(-17)
Simplify: y = 3(x+3)^2 -17
The vertex becomes the h and k values of (3,-17)
Answer:
I re-calculated many times and this is what i got.
1 is B
2 is A
Step-by-step explanation:
The answer would be D)90 degrees
When a polygon is both equilateral and equiangular it is called a regular polygon. So angles have to be equal and sides have to be equal...like a square..a square is a regular polygon. So ur answer is TRUE.
