There are 18 students in a class. Each day, the teacher randomly
Maurinko [17]
The answer is (3) 4896.

This number comes from multiplying 18 x 17 x 16

This is because any of the 18 students could be picked as a leader. Then, any of the remaining 17 students could be picked as a recorder. Then, any of the remaining 16 students could be picked as a timekeeper. Therefore, you multiply 18 by 17 by 16 to get 4896 combinations.

Find the derivative of the inverse function of the original function f(x)=(x+1)^3-5
____ [38]

Answer:

Step-by-step explanation:

let f(x)=y

y=(x+1)^{3} -5\\flip ~x~and~y\\x=(y+1)^{3}-5\\(y+1)^{3}=x+5\\y=(x+5)^{\frac{1}{3} } -1\\or~f^{-1}(x)=(x+5)^{\frac{1}{3} } -1\\(f^{-1})'(x)=\frac{1}{3} (x+5)^{\frac{-2}{3} }

What's the value of x y z
lions [1.4K]
They are algebraic symbols or known as unknown number. There is no true value for them. The value of algebraic symbols are based on equations

ie. 1+x = 2

First, we isolate the x by canceling the +1 FROM BOTH SIDES(Balance method) by -1 ON BOTH SIDES.

1+x-1 = 2-1

So we are left with the x on the left side, and a single number on the right side. Therefore, our calculation is complete.

x = 1


More complex cases would be

2y-3 = 45

First, we need to isolate the algebraic symbol, which is 2y (yx2) by +3 ON BOTH SIDES

2y-3+3 = 45+3

2y = 48

WE ARE NOT DONE! 2y=48 is still an equation. Therefore, to isolate the y, we need to divide BOTH SIDES by 2

2y/2 = 48/2

y = 24

There is no true or absolute or definite value for algebraic symbols like x,y,z,a,c,t,h,d etc. They are used to represent unknown numbers.


Hope this helped!
