Find the derivative of <br> y = 1/ (3x^3) with steps

Ganezh [65]

Answer:

$- 9 {x}^{ - 4}$

Step-by-step explanation:

$y = \frac{1}{ {3x}^{3} } = {3x}^{ - 3}$

$y = < - 3 \times 3 > {x}^{ - 3 - 1} \\ = - 9 {x}^{ - 4}$

At a pizza Parlour, you can order single, double, triple cheese in the crust. You also have the option to include ham, olives, p

ki77a [65]

Answer:

381 different types of pizza (assuming you can choose from 1 to 7 ingredients)

Step-by-step explanation:

We are going to assume that you can order your pizza with 1 to 7 ingredients.

If you want to choose 1 ingredient out of 7 you have 7 ways to do so.

If you want to choose 2 ingredients out of 7 you have C₇,₂= 21 ways to do so

If you want to choose 3 ingredients out of 7 you have C₇,₃= 35 ways to do so

If you want to choose 4 ingredients out of 7 you have C₇,₄= 35 ways to do so

If you want to choose 5 ingredients out of 7 you have C₇,₅= 21 ways to do so

If you want to choose 6 ingredients out of 7 you have C₇,₆= 7 ways to do so

If you want to choose 7 ingredients out of 7 you have C₇,₇= 1 ways to do so

So, in total you have 7 + 21 + 35 + 35 + 21 +7 + 1 = 127 ways of selecting ingredients.

But then you have 3 different options to order cheese, so you can combine each one of these 127 ways of selecting ingredients with a single, double or triple cheese in the crust.

Therefore you have 127 x 3 = 381 ways of combining your ingredients with the cheese crust.

Therefore, there are 381 different types of pizza.

Answer:

62°

Step-by-step explanation:

Since one arm making angle x is diameter. So, by inscribed angle theorem, we have:

$x = \frac{1}{2} (180 \degree - 56 \degree) \\ \\ x= \frac{1}{2} \times 124 \degree \\ \\ \huge \red{ \boxed{x = 62 \degree}}$

Solve for a: b − 2a = c

vlada-n [284]

Answer:

$a=-\frac{c-b}{2}$

Step-by-step explanation:

Solving for the variable $a$ , given that :

$b-2a=c$

We can first start start by subtracting $b$ from both sides of the equation:

$-2a=c-b$

Now, we can divide both sides of the equation by the coefficient of $a$ , which would be $-2$ :

$a=\frac{c}{-2}-\frac{b}{-2}$

Applying the fraction rule $\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}$ :

$a=\frac{c-b}{-2}$

Then, apply the fraction rule $\frac{a}{-b} =-\frac{a}{b}$

$a=-\frac{c-b}{2}$
