Answer:
a
Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ) , thus
A(- 1, - 1 ) → A'(1, 1 )
Answer:
p(-2) = -11
p(0) = -3
p(5) = 17
Step-by-step explanation:
<u>Step(i):</u>-
Given that the polynomial function p(x) = -3 +4x ..(i)
Given x =-2 , 0 and 5
put x =-2 in equation (i)
p(-2) = -3 +4(-2)
= -3 -8
p(-2) = -11
<u><em>Step(ii):-</em></u>
put x =0 in equation (i)
p(0) = -3 +4(0)
= -3 +0
p(0) = -3
<u><em>Step(iii):-</em></u>
put x = 5 in equation (i)
p(5) = -3 +4(5)
= -3 +20
p(5) = 17

The largest area that can be enclosed will be that of a square (140 ft)/4 = 35 ft on a side. Such a square has an area of (35 ft)² = 1225 ft², not enough for the garden to be 1300 ft². This tells us the solution to the equation you're being asked to write is non-real.
_____
Putting the given numbers in the area equation, you have
... 1300 = 70w -w²
Multiplying by -1 and completing the square, we have
... w² -70w +35² = -1300 +35²
... (w -35)² = 1225 -1300 = -75
Taking the square root shows us the solution is non-real.
... w - 35 = ±√(-75) = ±5i√3
... w = 35 ± 5i√3 . . . . . . . . . after adding 35. These are complex solutions.
