Write the prime factorization of 48. use exponents when appropriate and order the factors from least to greatest

horrorfan [7]

What can be divided? For example, for 48 you can divide 1, and 48 and you can also divide it by two which equals to 24 so keep writing that from least to greatest. You don't have repeat answers.

If x = -3 and y = 4x - 1, then y equals what number

Masteriza [31]

$\huge\text{Hey there!}$

$\large\textsf{y = 4x - 1}$

$\large\text{If x= -3, then substitute it into the given equation}$

$\large\textsf{y = 4(-3) - 1}$

$\large\textsf{4(-3) = \boxed{\bf -12}}$

$\large\textsf{y = -12 - 1}$

$\large\textsf{-12 - 1 = y}$

$\large\textsf{-12 - 1 = \boxed{\bf -13}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf y = -13}}}\huge\checkmark$

Nina [5.8K]

The maximum units is 200 and , Total revenue is $8,000

<u>Step-by-step explanation:</u>

Here we have , A manufacturer finds that the revenue generated by selling of cortan commodity is given by function R(x)=80x-0.2x^ 2 , where he maximum reveremany should be manufactured to obtain this maximum units .Let's find out:

We have following function as $R(x)=80x-0.2x^ 2$ . Let's differentiate this and equate it to zero to find value of x for which the function is maximum!

⇒ $R(x)=80x-0.2x^ 2$

⇒ $\frac{d(R(x))}{dx}=\frac{d(80x-0.2x^ 2)}{dx}$

⇒ $\frac{d(R(x))}{dx}=\frac{d(80x)}{dx}-\frac{d(0.2x^ 2)}{dx}}$

⇒ $0=80-2x(0.2)$

⇒ $\frac{80}{0.4}=x$

⇒ $x=200$

Now , Value of function at x=200 is :

⇒ $R(200)=80(200)-0.2(200)^ 2$

⇒ $R(200)=16000-8000$

⇒ $R(200)=8000$

Therefore , The maximum units is 200 and , Total revenue is $8,000
