Differentiate f(x) = \frac{x^{3}-4 x+1}{x^{3}}.
miv72 [106K]
f(x) = \frac{x^{3}-4 x+1}{x^{3}}\\
f'(x)=\frac{(3x^2-4)\cdot x^3-(x^3-4x+1)\cdot3x^2}{x^6}\\
f'(x)=\frac{x^2(3x^3-4x-3x^3+12x-3)}{x^6}\\
f'(x)=\frac{8x-3}{x^4}\\

The ratio of violinists to cellists in the school orchestra must always be 7:3. If the school orchestra has 21 violinists, what
Papessa [141]

Given:

Violinists : Cellists = 7:3.

Number of violinists in the school orchestra = 21

To find:

The combined number of cellists and violinists.

Solution:

Let the number of violinists and cellists in the school orchestra are 7x and 3x respectively.

Then, combined number of cellists and violinists is

\text{Combined number of cellists and violinists}=7x+3x

\text{Combined number of cellists and violinists}=10x      ...(i)

Number of violinists in the school orchestra = 21

7x=21

Divide both sides by 7.

x=3

Now, the combined number of cellists and violinists is

\text{Combined number of cellists and violinists}=10(3)    [Using (i)]

\text{Combined number of cellists and violinists}=30

Therefore, the combined number of cellists and violinists is 30.

Can someone please help me!!
Elan Coil [88]

Answer:

13

Step-by-step explanation:

Firstly we would start off by simplifying the equation by doing the order of operations backward (PEMDAS -> SADMEP) and multiply -4 and -3 which would equal a positive 12

Next, we would divide 12 and -6 and get a negative 2

Finally, we would have the equation 1 - 12 + (-2)

We would solve the equation to get -13/(-1)³

This would make the -13 into a positive since any number over one is a whole number. -13 is getting divided by (-1) 3 times so it converts to a positive, then a negative, then back to a positive.

I hope this helped :3
