Answer:
bet
Step-by-step explanation:
It would be 100. Hope it helps!
Shaded area = Circle area - Rectangle area
Shaded area = 3.14 × (4)^2 - 5 × 6
Shaded area = 3.14 × 16 - 30
Shaded area = 50.24 - 30
Shaded area = 20.24
Shaded area = 20.2
Following with the extra hint that x = 82.03 m
There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:
Plug x = 82.03
=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m
Please take the time and understand the answer instead of just looking at the final result.
Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>
