What is the real number value of m^3+ √12 m when 5m^2 = 45 ?

babymother [125]

<h3>Answer: H. 33</h3>

=============================================

Work Shown:

Solve 5m^2 = 45 for m to get

5m^2 = 45

m^2 = 45/5

m^2 = 9

m = sqrt(9)

m = 3

I'm making m to be positive so that way the expression 12m is not negative. Otherwise, sqrt(12m) would not be a real number result.

--------------

Plug m = 3 into the expression we want to evaluate

m^3 + sqrt(12m)

3^3 + sqrt(12*3)

27 + sqrt(36)

27 + 6

A candy maker is making candy canes to sell over the holidays she has 45 left over the last month sale and she can make 225 per

notsponge [240]

F(x) stands for a function, and if x stands for the number of days, than she can do 225 per day, which would be the multiplication to find the toatl 225x.

Then, with 45 extra, we add that to the equation:

F(x) = 225x + 45

Answer: F(x) = 225x + 45

Suppose that Bob leaves a job that pays $100,000 per year in order to open a new sponge business. His insurance cost is $8,000,

tensa zangetsu [6.8K]

Answer:

-$11,000 is the economic profit or we can say it is a loss.

Step-by-step explanation:

The job paid Bob = $100000

The insurance cost is = $8,000

The material cost is = $15,000

The lease payments are = $8,000

The sales revenue is $120,000.

So, Bob's economic profit is: $120000-100000-8000-15000-8000=-11000$

Therefore, his economic profit is -$11000.
