It can lie between any number lower than it and any number high than it.
For example, 419 and 421
Answer:
37.7 m
Step-by-step explanation:
Use this formula:
A=2πrh+2π![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
Answer:
See explanation
Step-by-step explanation:
Given that the equation for the firecracker is h = − 5 t^2 + 30 t + 20
It is impossible to solve this question unless the height (h) in meters is supplied. If the height was supplied, we could set up the quadratic equation and solve it yielding two values for the time. The values of t obtained is the time in seconds required for the firecracker to reach the given height h.
You can apply these tips and solve the question seamlessly.
Answer:
n=14/5
Step-by-step explanation:
4n+n-16=-2
We move all terms to the left:
4n+n-16-(-2)=0
We add all the numbers together, and all the variables
5n-14=0
We move all terms containing n to the left, all other terms to the right
5n=14
n=14/5
Answer:
4n + 5
Step-by-step explanation:
This equation cannot be simplified further
Unless you meant 4n + 7 <em>=</em> 2
Then the answer would be -1.25
