-5x-3y^3
Step-by-step explanation:
x-3y^3+3x^3-5x-x^3-x-2x^3
Answer:
Part A: A(m(t)) = π(81t²); Part B: 1017.36
Step by step explanation:
Part A:
To find A(m(t)), we substitute our value for m(t), 9t, in place of m:
A(m(t)) = πm² = π(9t)² = π(81t²)
A(m(t)) = π(81t²)
Part B:
Substitute 2 in for t:
A(m(2)) = π(81(2²)) = π(81(4)) = 3.14(324) = 1017.36

Answer:
The answer is 3 inch
Step-by-step explanation:
To start off, the equation you want to use the formula V=whl
Next, you simply plug in the values you already know, so you have 450=w*20*7.5
After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.
Answer:
C
Step-by-step explanation:
From the graph you can see that y changes from -2 to 2, so the range of the function is ![[-2,2].](https://tex.z-dn.net/?f=%5B-2%2C2%5D.)
Since the range of the functions 
and 
is ![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
and the range of the functions 
and 
is ![[-k,k],](https://tex.z-dn.net/?f=%5B-k%2Ck%5D%2C)
we can state that the correct option is C: 
Check the value at t=0:
