Answer:
484 feet is the answer.
Step-by-step explanation:
Maximum value of f(t) =
is given by when t =
which give t = 5.5 seconds
maximum height is when we plug t = 5.5 seconds in equation
more over time of flight is 11 seconds (given )
it will be at its maximum when time is half of 11 seconds.
that is 5.5 seconds
maximum height is obtained by plugging t = 5.5seconds.
f(5.5) = -16(5.5)(5.5) + 176(5.5)
= -484 +968
= 484 feet

Answer:
Step-by-step explanation:
If we let x be the amount of live bait and y be the amount of natural bait, Then we can come up with the following inequalities;
We are told that John would like to get at least 3 pounds of live bait. At least 3 means 3 or more. Since x represents the amount of live bait, we have;
Moreover,we are informed that;
The store sells live bait for $12 a pound and natural bait for $7 a pound. x pounds of live bait would cost 12x while y pounds of natural bait would cost 7y. The total cost would thus be;
12x + 7y
but John only has a budget of $63. This implies that he can spend $63 at most, thus;
Finally we can have our last inequality as;
