Answer:
Step-by-step explanation:
IT is a rational number because an irrational number cannot be expressed as a fraction.
Hello! our answer here is going to be:
43.
Lets understand this a little better!
when dealing with exponents, it is the base number (3) times its self how ever many the above number is (3 again)
so, it wont be 3 x 3, but instead 3 x 3 x 3 because that's how much the exponent is.
same rule applies with 4^2!
The correct answer would be 23% because 28+34+40+22=124, and if you do the butterfly method you would multiply 28 by 100 and you get 2800 then divide that by 124 and you get 22.5% but since you have to round to the nearest percent it's 23%
Answer:
The maximum height is:
The ball reaches the ground in 1.79 s.
Step-by-step explanation:
We need to take the derivative and equal to zero to find the time at the maximum height.
(1)
![\frac{dh(t)}{dt}=-32t +27=0](https://tex.z-dn.net/?f=%5Cfrac%7Bdh%28t%29%7D%7Bdt%7D%3D-32t%20%2B27%3D0)
![t_{max} =\frac{27}{32}](https://tex.z-dn.net/?f=t_%7Bmax%7D%20%3D%5Cfrac%7B27%7D%7B32%7D)
![t_{max} =0.84\: u](https://tex.z-dn.net/?f=t_%7Bmax%7D%20%3D0.84%5C%3A%20u)
Now, we just need to put t(max) into equation (1) to find h(max)
If we want to get the time when the ball reaches the ground we just need to equal h(t) to zero.
![0=-16t^{2} +27t+3](https://tex.z-dn.net/?f=0%3D-16t%5E%7B2%7D%20%2B27t%2B3)
Let's solve this quadratic equation.
We will get two solutions and we must choose the positive value.
t1 = 1.79 u
t2 = -0.10 u
Therefore, the ball reaches the ground in 1.79 u.
I hope it helps you!
