Answer:
t = 4 seconds
Step-by-step explanation:
The height of the projectile after it is launched is given by the function :
t is time in seconds
We need to find after how many seconds will the projectile land back on the ground. When it land, h(t)=0
So,
The above is a quadratic equation. It can be solved by the formula as follows :
Here, a = -16, b = 32 and c = 128
Neglecting negative value, the projectile will land after 4 seconds.
Answer:
19
Step-by-step explanation:
1/4 are animal. 28/4 = 7
2 are adventure.
7+2 = 9
9 are not mystery

19 are mystery.
Answer: 1.92 x 10^8
Step-by-step explanation:
Answer:D 2 1/7
Step-by-step explanation: you can put 7 into 15 two times and that gives you 2 holes and you then have 1/7 leftover therefore you have 2 1/7.
The value of T in the equation if v = 42 is 12
<h3>How to solve algebra</h3>
Given:
T= v /6 + 5
If v = 42, find T
- substitute 42 for v in the equation
T= v /6 + 5
T = 42/6 + 5
T = 7 + 5
T = 12
Therefore, the value of T in the equation if v = 42 is 12
