Axis of symmetry shows the min/max. its a max in this case and its at t=1.5
so the ans is <span>t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground</span>
B. 3.5( b + c ) - 28.09
C. $108.41
Step-by-step explanation:
The best expression to use to find the total profit of Cindy's pie is 3.5(b+c) - 28.09. The total profit is the total revenue - total cost.
To put it into perspective, let's try an example.
b = 5
c = 12
Total profit = 3.5(b + c) - 28.09
= 3.5 (5 + 12) - 28.09
= 3.5 (17) - 28.09
= 59.5 - 28.09
Total profit = $31.41
Now for part B, we simply use the expression and substitute the values.
b = 24
c = 15
Total profit = 3.5(b + c) - 28.09
= 3.5(24 + 15) - 28.09
= 3.5(39) - 28.09
= 136.5 - 28.09
Total profit = $108.41

The surface area of a right circular cone is SA =<span>
</span>
The diameter (d) is equal to 20 meters and half of it is equal to the radius which is 10 meters.
The height (h) of the tank is equal to 42 meters.
Substituting the given to the equation:
SA =
= 1670.51 square meters or the closest answer is 1,671 m2
