To find all the different possible combinations, you multiply all the possibilities for each position.

1st - she as 20 different possible buttons
2nd - she would have 19 possible buttons
3rd-she would have 18 possible buttons

20 x 19 x 18=6840 possible ways to choose these buttons.

What is the partial derivative of a given function
Marizza181 [45]
Partial differentiation of a function with more than one variables refers to its derivative being taken with respect to one of those variables, while the rest being held as a constant.

An example is the volume of a cylinder given by:
V(h, r) = \pi r^{2}h

The volume requires two variables in order to work out the volume, namely the radius and the height.

Using partial differentiation, its partial derivative can become:
\frac{\partial V}{\partial r} = 2\pi rh

This symbol is used in place of the derivative symbol, in order to distinguish total derivatives and partial derivatives.

(420,104)(720,164)
slope = (164 - 104) / (720 - 420) = 60/300 = 1/5

y = mx + b
slope(m) = 1/5
(420,104)...x = 420 and y = 104
now we sub and find b, the y int
104 = 1/5(420) + b
104 = 84 + b
104 - 84 = b
20 = b

so ur equation is : y = 1/5x + 20

What is the equation of the line x–3y=18in slope-intercept form?
Alekssandra [29.7K]

Answer:

y=\frac{1}{3} x-6

Step-by-step explanation:

Write down the slope-intercept form:

y=mx+b

Where m is the slope and b is the y-intercept.

To turn the equation into slope-intercept form, isolate y on the left-hand side:

x-3y=18\\-3y=18-x\\y=-6+\frac{x}{3} \\

Rearrange the equation a bit:

y=\frac{1}{3} x-6
