Answer:
About 4.1323 meters.
Step-by-step explanation:
We can use the following kinematic equations:

We want to determine the distance the object has dropped after falling from rest and reaching an instantenous speed of 9 m/s.
We are given that the acceleration due to gravity is 9.8 m/s².
Using this fact and the first equation, find the time for which it took the object to reach 9 m/s. Note that the initial velocity is 0 m/s since the object started from rest.

To find how far the object dropped, we can use the second equation:

In conclusion, the object would have dropped about 4.1323 meters.
(m^4 + m^3 + 4) + (-5m^4 + 4m + 1) =
m^4 + (-5m^4) + m^3 + 4m + 4 + 1 =
-4m^4 + m^3 + 4m + 5
The answer is B
Answer:What do u need help with?
Step-by-step explanation:
Part A:
What is the cost of 5.15 pounds of ground beef, if 1 pound = $3.40
Multiply the cost of 1 pound per how many pounds there are:
3.40 * 5.15 = $17.51
It costs $17.51 for 5.15 pounds of ground beef at $3.40 per pound
Part B:
Assuming the cost of the burger is only determined by the cost of ground beef.
The cost of the 17 burgers is $17.51
We divide $17.51 by 17, to find out the cost of each burgr
$17.51 / 17 = $1.03
The cost of ground beef per burger is $1.03
