Answer:

1/2, 0.6, 8/10, 0.9

Step-by-step explanation:

Turn them all into decimals or into fractions (i chose decimals)

1/2 as a decimal is 0.5

0.6 is already in decimal form

8/10 as a decimal is 0.8

0.9 is already in decimal form

then just order the numbers and turn them back into the original :)

I hope that helps you :)

Find the inverse of the function.

asambeis [7]

Answer:

A) $f^{-1}(n)= (n+2)^3$

Step-by-step explanation:

$f(n) = \sqrt[3]{n} -2$

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

$y = n^{1/3}-2$

$n = y^{1/3} -2$

$n + 2 = y^{1/3}$

$y = (n + 2) ^3$

$f^{-1}(n) = (n + 2)^3$

Hope this helps!

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9 k

nadya68 [22]

Answer:

6 kg

Step-by-step explanation:

Given is weight of an object directly varies with the mass of the object .

Let the constant of proportionality be k

So,

Weight = K×(mass of the object)

For an object , weight = 45 N

mass = 9 kg

So , 45 = K×9

K = 5.

Now, for the other object ,

Weight = 30 N. K = 5 (as obtained above)

So, 30 = 5×(mass of the object)

mass of the object = 6 kg.

What is the simplified expression for Negative 3 (2 x minus y) + 2 y + 2 (x + y)?

Lana71 [14]

Answer:

$7y - 4x$

Step-by-step explanation:

$-3 (2x-y)+2y+2(x+y)\\$

Step 1: Open the brackets

$= -6x+3y +2y +2(x+y)\\=-6x +3y + 2y +2x + 2y$

Step 2: Bring the similar variables together

$=-6x +2x \ +3y + 2y + 2y$

Step 3: Simplify by adding/subtracting the coefficients of the similar variables

$= - 4x +7y$

Step 4: Rearrange as required.
