Steps to solve:
f(x) = 3x³ – 2x² + x; x = -3
~Substitute
f(-3) = 3(-3)³ - 2(-3)² + (-3)
~Solve the exponents
f(-3) = 3(-27) - 2(9) + (-3)
~Multiply
f(-3) = -81 - 18 - 3
~Subtract
f(-3) = -102
Best of Luck!
Answer: 42
Step-by-step explanation:
Let A represents the number of freshmen participated in sports and B represents the number of freshmen participated in clubs.
Then , we have given that
Using formula
We have,
Now, the number of students are involved in just sports is given by :-
Hence, 42 students are involved in just sports.
The answer is 2 drinks left
Answer:
(r^2 - r - 1)(r^2 + r - 1).
Step-by-step explanation:
r^4 - 3r^2 + 1
We need to make this into a perfect square so the r^4 and the 1 fit the bill but not the -3r^2 so we have to correct for that.
A perfect square would be:
r^4 - 2r^2 + 1 ( = (r^2 - 1)^2 )
But we need -3r^2 so we add - r^2 at the end:
= (r^4 - 2r^2 + 1) - r^2 So now we have the difference of 2 squares and we write:
(r^2 - 1)^2 - r^2
= (r^2 - 1 - r)(r^2 - 1 + r)
= (r^2 - r - 1)(r^2 + r - 1)
OK you have to find the volume of it. So you have to do multiple. Here want I got
