Byron bought a keyless entry door lock that has the digits 0 through 9 on the keypad. He wants to choose a three-digit entry cod

Ivenika [448]

There are, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So 720 different combinations are possible.

The transformation of 'f' is represented by 'g'. Write a rule for g. f(x)=\root(3)(x). Then show your check steps.

podryga [215]

Answer:

$g(x)=-2\sqrt[3]x$

$g(x) = -2f(x)$

Step-by-step explanation:

Given

$f(x) = \sqrt[3]x$

Required

Write a rule for g(x)

See attachment for grid

From the attachment, we have:

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (1,-2)$

We can represent g(x) as:

$g(x) = n * f(x)$

So, we have:

$g(x) = n * \sqrt[3]x$

For:

$(x_1,y_1) = (-1,2)$

$2 = n * \sqrt[3]{-1}$

This gives:

$2 = n * -1$

Solve for n

$n = \frac{2}{-1}$

$n = -2$

To confirm this value of n, we make use of:

$(x_2,y_2) = (1,-2)$

So, we have:

$-2 = n * \sqrt[3]1$

This gives:

$-2 = n * 1$

Solve for n

$n = \frac{-2}{1}$

$n = -2$

Hence:

$g(x) = n * \sqrt[3]x$

$g(x)=-2\sqrt[3]x$

or:

$g(x) = -2f(x)$

The volleyball team and the wrestling team at Belmont High School are having a joint car wash today, and they are splitting the

Keith_Richards [23]

Answer:

10 cars

Step-by-step explanation:

volleyball team = past money + money from car wash = 40 + 2 per car = 40 + 2 * number of cars

wrestling team = past money + money from car wash = 50 + 1 * number of cars

set the two equal to each other because they raise the same amount

40 + 2 * number of cars = 50 + 1 * number of cars

set number of cars to n

40 + 2n = 50 + n

subtract n from both sides to put all the variables on one side

40 + n = 50

subtract 40 from both sides to find n

n = 10

PLS HELP ME WITH THIS I BEG

m_a_m_a [10]

Answer:

y=-3x-1

Step-by-step explanation:

We khow the the equation of the graph function have this form : y=mx+c

Let f be our function
m= (f(1)-f(-1)]/[1-(-1)]=(-4-2)/2= -3
so y= -3x+c
let's replace x and y by the coordinates of a khown point to calculate c

(1, -4) ⇒ -4= -3*1+c ⇒ c= -4+3 ⇒ c= -1
y= -3x-1
