Answer:
5
Step-by-step explanation:
there is not enough info to because we do not have the detentions are the difference of triangle A or B
Part A:
To determine the values of the times to which the height of the two cannon balls are the same, we equate the given functions.
H(t) = g(t)
Substitute the expressions for each.
-16t² + 48t + 12 = 10 + 15.2t
Transpose all the terms to the left-hand side of the equation.
-16t² + (48 - 15.2)t + (12 - 10) = 0
Simplifying,
-16t² + 32.8t + 2 = 0
The values of t from the equation are 2.11 seconds and -0.059 seconds
Part B:
In the context of the problem, only 2.11 seconds is acceptable. This is because the second value of t which is equal to -0.059 seconds is not possible since there is no negative value for time.
1. The coefficient of the squared term (-1/3) is negative, so the graph opens downward.
2. Matching the pattern to
.. y = a(x -h)^2 +k
we find (h, k) = (-2, 5) . . . . . . selection C
3. See the previous answer. The axis of symmetry is
.. x = h
Since h = -2, the axis is x = -2. . . . . . selection B

Step-by-step explanation:
im jk the answer is 6 bc u multiply them and divide by 8 u would then divide that by 2
B Multiply each term by - 1
