<h3>
Answer: 17</h3>
==================================================
Explanation:
We'll start things off by computing the inner function u(2)
Plug x = 2 into the u(x) function
u(x) = -x-1
u(2) = -2-1
u(2) = -3
This tells us that w(u(2)) is the same as w(-3). I replaced u(2) with -3.
We'll plug x = -3 into the w(x) function
w(x) = 2x^2-1
w(-3) = 2(-3)^2 - 1
w(-3) = 2(9) - 1
w(-3) = 18-1
w(-3) = 17
Therefore, w(u(2)) = 17
------------------------
Here's a slightly different approach:
Let's find what w(u(x)) is in general
w(x) = 2x^2 - 1
w(u(x)) = 2(u(x))^2 - 1
w(u(x)) = 2(-x-1)^2 - 1
Then we can plug in x = 2
w(u(x)) = 2(-x-1)^2 - 1
w(u(2)) = 2(-2-1)^2 - 1
w(u(2)) = 2(-3)^2 - 1
w(u(2)) = 2(9) - 1
w(u(2)) = 18 - 1
w(u(2)) = 17
I can’t see that well can you show it more clearly
Im assuming you just want to take out common multiples so,
30d+18 is also the same as 6(5d+3)
Answer:
350 feet per minute
Step-by-step explanation:
The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.
This means it took 104 minutes for the plane to descend 36,400 feet.
Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.
