the transformation (x, y) → (x, y- 4) , means the x-coordinate remains unchanged, while the y-coordinate has 4 subtracted from it, for example
the points on the diagram
A(1, 5 ) → A'(1, 5 - 4) → A'(1, 1)
B(4, 5) →B'(4, 5 - 4) → B'(4, 1)
C(4, 3) → C'(4, 3 - 4) → C'(4, - 1)
D(2, 2) → D'(2, 2- 4) → D'(2, - 2)
Answer:
33.44 cm²
Step-by-step explanation:
sorry if incorrect
DI/dx=-850x+45500
d2l/d2x=-850 so when dl/dx=0 it is an absolute maximum for l(x)...
dl/dx=0 only when:
850x=45500
x=53.53
x=54 years of age (rounded)
