We are to find how long will it take to return to the ground?
Answer:
t = 0.48 sec
Step-by-step explanation:
We are given;
initial velocity; vi = 40 ft/s
hi = 70 ft
acceleration due to gravity; a = 32 ft/s²
Now, we are given that the rocket's height as a function of time is;
h = -12at² + vit + hi
At ground, h = 0
Plugging in the relevant values to obtain ;
0 = -12(32)t² + 40t + 70
-384t² + 40t + 70 = 0
The roots of the equation gives; t = 0.48 sec
275-100=175 (amount of bonus) 175÷5 (amount per bonus)= 35 total sales
Answer: $95.7
Step-by-step explanation:
580 x 5.5% = 31.9 x 3 =95.7
$95.7
The summary of the ruler placement postulate is given as:
- there is a one-to-one correspondence between the set of points on the line and the set of real numbers, and.
- the distance between two points equals the absolute value of the difference between the corresponding numbers.
<h3>What is the ruler placement postulate?</h3>
This states that the points of a line can be matched and correspond to a set of points on the line and the set of real numbers,
Therefore, based on the fact that your question is incomplete, a general overview of the ruler placement postulate is given to give you a better understanding of the concept.
