Which weighs more: a pound of feathers or a pound of rocks?

2 answers:

8 0

They both weigh the same. They are both a pound each. One rock may weigh a pound where a thousand feathers may weigh a pound, but they still are both the amount needed to be a pound each. <span />

How to find restrictions for x??<br> 3. F(x)=2 sqrt x-4

stealth61 [152]

Answer:

none
none
x ≥ 4

Step-by-step explanation:

The restrictions placed on the independent variable in a function are those necessary to ensure that the function is defined for all allowed values of that variable.

In the graphs of problems 1) and 2), we see that the functions are defined for all values of x, so there are no restrictions.

3. For the function ...

$f(x)=2\sqrt{x-4}$

the value under the radical cannot be negative. The square root function is not defined for negative values, so the restriction is ...

x -4 ≥ 0

x ≥ 4 . . . . . . . add 4 to both sides of the inequality

Monique worked for 4 hours and earned $39.79. How much would she earn if she worked for 6 hours? I HELP WITH IT RNN

loris [4]

Answer:

x=$59.69

Step-by-step explanation:

We can create a proportion to find the answer.

Thus, we get 4 hr/$39.79=6 hr/$x.

Cross multiplying gives us 4x=238.74, and solving for x gives us $59.685.

We can round to $59.69.
