Answer:
it's a /
Step-by-step explanation:
Given:
Vertices of a triangular garden:
A(4,2)
B(2,4)
C(6,4)
Scale factor = 0.5
Find the distance between points:
d = √(x2-x1)^2 + (y2-y1)^2
dAB = 2√2
dBC = 4
dCA = 2√2
A similarly shaped garden is to be created using the scale factor, 0.5:
A' = 2√2 / 0.5 = 4√2
B' = 4 / 0.5 = 8
C' = 2√2 / 0.5 = 4√2
If you want midpoint it would be (2,5)
If you want endpoint it would be (5,8)
Answer:
The roots are not real.
Step-by-step explanation:
To prove : The roots of I/2 +9 (1-k) are real for all real values of k ?Solution :
The roots are real when discriminant is greater than equal to zero.
i.e b2-4ac>0 But the roots are imaginary therefore the roots of the given equation are not real for any value of k.If x²+kx+k=0, find the value of k, If the roots are real & equal.
