Answer:

This is about a function evaluated at a particular point. You don't get a formula for the function, but there is enough information to say that the ordered pair (-2, 3) is part of the function.

The function's name is f.

The -2 in parentheses is a value for the independent variable ("input"), often designated by the variable x.

The 3 is the corresponding value of the dependent variable ("output"), often designated by the variable y.

The expression can be read as:

"f of negative two is equal to 3"

"the value of f at -2 is 3"

Calculate the quotient below and give your answer in scientific notation. 2.64*10^-3\8.0*10^0

Zolol [24]

Answer:

The quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

Step-by-step explanation:

We need to find quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$

We know that $10^0=1$

Now solving:

$\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033$

Writing it in scientific notation

$0.00033\\=3.3\times10^{-4}$

So, the quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

What is the answer for. What is hg = 45g

goldenfox [79]

To solve hg = 45g

Apply Multiplication Property of Equality which is to multiply both sides of the equation with 1/g.

hg (1/g) = 45g (1/g)
   h = 45

Or you can divide both sides with the equation with g.

   hg / g = 45g / g

You can cancel g to both sides.
Then,
   h = 45

If Judy completes a puzzle by herself, it takes her 3 hours. Working with Sal, it only takes them 2 hours.What is the missing va

aliina [53]

Answer:

It means the Judy's rate to complete the puzzle is $\frac{1}{3}.$

Step-by-step explanation:

If Judy completes a puzzle by herself, it takes her 3 hours.

Working with Sal, it only takes them 2 hours

We have been given the rates of time taken by Judy and Sal to complete a puzzle.

We can see from our given table that Sal's rate is r. We are told that Judy completes a puzzle by herself, it takes her 3 hours. working with Sal, it only takes them 2 hours.

It is given that Judy completes a puzzle by herself, it takes her 3 hours.

so part of puzzle completed by Judy in one hour would be $\frac{1}{3}$
