Answer:
2560
Step-by-step explanation:
5120 divided by 2
f=2560
Given t = time and h = height
![h(t) = - 16(t - 1)^{2} + 16](https://tex.z-dn.net/?f=h%28t%29%20%3D%20%20-%2016%28t%20-%201%29%5E%7B2%7D%20%20%2B%2016)
From the equation.
![y = a(x - h)^{2} + k](https://tex.z-dn.net/?f=y%20%3D%20a%28x%20-%20h%29%5E%7B2%7D%20%20%2B%20k)
h is the axis od symmetry
(h, k) is the vertex.
In the equation, h is 1 and k is 16.
So the maximum value is 16 at t = 1.
The ball reaches maximum at 16 and it takes t = 1 to reach the maximum point.
2. Eight cards are marked : (3,4,5,6,7,8,9,10), such that each card has
exactly one of theses numbers. A card is picked without looking.
Determine the probability of choosing a number greater than 5. (decimal)
A .625
B 1.75
C .50
D .60
The answer is C.
Answer:
3 * 10^3 in scientific notation.
3,000 in standard notation.
Step-by-step explanation:
We divide:
3.9 *10^5 / 1.3 * 10^2
= ( 3.9/1.3) * (10^5 / 10^2)
= 3 * 10(5-2)
= 3 * 10^3.
This equals 3 * 1,000 = 3000.
