Answer:
0.064
Step-by-step explanation:
(2/5) * (2/5) * (2/5)
= 0.064
Hope this is helpful!!! :)
Since you are given the function for the height of a rocket, we are to look for the value of X that gives us a value of p(x) = 0, which means that the model rocket has landed back onto the ground. One easy way to do this is by table method, meaning we substitute values of x to see if we can obtain the needed value of P(x). We should start from 1, since using 0 as our first value means that the rocket has not even launched up yet. Let us do this below:
x | <span>p(x) = -16x^2+32x
--------------------------
1 | p(1) = -16(1)^2 + 32(1) = 16
</span><span>2 | p(2) = -16(2)^2 + 32(2) = 0
</span>
Having obtained the desired result at x = 2, this means that the model rocket has been in the air for 2 seconds.
1. Did it mentally think it’s 16. Make sure to yield to order of operations.
2. Because none of the operations are multiplication or division, parenthesis can be put anywhere that isn’t between exponents and it will yield 22.
Subtract 5n from both sides
5-9n <8
Subtract 5 from both sides
-9n <3
Divide both sides by negative 9.
n <1/3
To check:
5-4 (1/3)<8-5 (1/3)
OR
Add 4n to both sides
5 <8-n
Subtract 8 from both sides
-3 <-n
Divide both sides by negative 1
3 <n
To check:
5-4 (3)<8-5 (3)
-7 < -7
The first way is your right answer.
6-/6
Sorry can’t show the root. It’s 6 and then the symbol with 6 inside the symbol.
