Answer:
a=31
Step-by-step explanation:
1/2(a-9)=11
a-9=22
a=22+9
a=31
Are you rounding to the nearest 100’s place?
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
Random number generator method evenly assigns the students to the two dormitories.
- Using a random number generator, assign each incoming female freshman a number, eliminating duplicate numbers.
- After each incoming female freshman is assigned a number, list the assigned numbers in ascending order.
- Assign the first 400 numbers on the ascending list to Williams dormitory, and assign the last 400 numbers on the ascending list to Hillside dormitory.
<h3>What is Random number generation?</h3>
- Random number generation is a process by which, often by means of a random number generator, a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated.
- Random numbers are useful for a variety of purposes, such as generating data encryption keys, simulating and modeling complex phenomena and for selecting random samples from larger data sets.
