Answer:
side of the pool = 11 m
Step-by-step explanation:
<u>Square Plot:</u>
side = 35 m
Area = 35 * 35 = 1225 sq.m
Area of lawn = 1104 sq.m
<u>Swimming pool:</u>
Area of the Swimming pool = 1225 - 1104 = 121 sq.m
side * side = 121 = 11 * 11
side = √11 * 11
side of the pool = 11 m
B
given f(x) in factored form, equate to zero for x-intercepts
(x - 8)(x - 4) = 0, hence
x = 4, x = 8 ← x- intercepts
The vertex lies on the axis of symmetry which is situated at the midpoint of the x- intercepts
x- coordinate of vertex =
= 6
f(6) = (6 - 8 )(6 - 4 ) = -2 × 2 = - 4 ← y-coordinate
vertex = (6, - 4 ) → B
A=8
B=10
Hope this helps :D
