Answer:
<h2>84feet</h2>
Step-by-step explanation:
Given the height of the ball modelled by the equation h(t)=16t²+84 after t secs. At the maximum height, the velocity of the ball is zero.
Velocity V is the change of rate of displacement.
V = dh/dt = 32t
0 = 32t
t = 0secs
at t = 0;
h(0) = 16(0)²+84
h(0) = 84feet
This shows that the maximum height of the ball is 84feet
Answer:
y=4x-5
Step-by-step explanation:
1 Quart = 4 Cups
So, 6 Quarts = 24 Cups
Answer:
90 quizzes
Step-by-step explanation:
In 7 weeks, 63 quizzes
In 10 weeks, x quizzes
Making a proportion,
7/10 = 63/x
Cross multiplying,
7x = 630
Dividing by 7 on both sides,
x = 90 quizzes
A.
The spinner can land on 1, 2, 3, 4, 5, 6, 7, or 8, so the sample space is {1, 2, 3, 4, 5, 6, 7, 8}.
Choice A applies.
B.
1, 2, 3 are part of the sample space, so choice B applies.
C.
9 is not in the sample space, so choice C does not apply.
D.
4 is in set A. 4 is not less than 4, so choice D does not apply.
E.
The set of spinning an odd number is {1, 3, 5, 7}.
Removing these elements from the original sample space leaves the complement (2, 4, 6, 8}. Choice E applies.
Answer: A, B, E
