The graph below shows the value of Edna's profits f(t), in dollars, after t months:graph of quadratic function f of t having x intercepts at 6, 0 and 18, 0 and vertex at 12, negative 36

What is the closest approximate average rate of change for Edna's profits from the 12th month to the 18th month?

(A)5.92 dollars per month
(B) 3.75 dollars per month
(C) Five dollars per month
(D) Nine dollars per month

Answers

Average rate of change=(0-(-36))/(18-12)= (36)/(6)=6
The closest approximate average rate of change is :A) 5.92 dollars per month.

Based on the calculations, the closest approximate average rate of change for Edna's profits is equal to 5.92 dollars per month.

How to calculate the closest approximate average rate of change?

In order to calculate the closest approximate average rate of change based on the values contained in the graph, we would use the slope formula as follows:

Slope = (Change\;in\;y\;axis)/(Change\;in\;x\;axis)\n\nSlope = (y_2\;-\;y_1)/(x_2\;-\;x_1)

Substituting the given points into the formula, we have;

Slope = (0\;-\;(-36))/(18\;-\;12)\n\nSlope = (36)/(6)

Slope = 6.

Therefore, the closest approximate average rate of change for Edna's profits is equal to 5.92 dollars per month.

A room is 45 m x 15 m. What is the least number of rectangle tiles required to pave the floor of the room, if each tile is 50 cm x 1m?

Answers

Hey Batala426,

If the room is 45m x 15m, then the total area is 675 metres squared.
Each tile is 50cm x 1m, so the area of each one is 0.5 metres squared.

675 / 0.5 = 1350

So the least number of tiles you need to pave the whole room is 1350 tiles.

Hope this helps!

can anyone solve 4x^2 + 12x - 40 ? you would have to find what multiplies to get -40 but adds to get 12, but you do something with th 4x^2 as well

Answers


There's really nothing to solve, since there's no equation there.
Perhaps you want that expression factored.  We can do that.

First, all 3 terms share a common factor of 4.  Let's pull that out,
and see what's left to be factored:

                   4x² + 12x - 40  =  4 (x² + 3x - 10) .

Now, the expression left inside the parentheses looks
like it might be a lot easier to handle. 

Here's what the whole expression looks like after the
quadratic inside the parentheses is factored:

            4 (x² + 3x - 10)  =    4 (x + 5) (x - 2) .

There it is.  Understand ... we haven't changed anything,
and we haven't solved anything.  We only wrote the original
expression in a different form.  It's still just an expression that
stands for a number, and we won't know the number until
somebody tells us the value of 'x' .

What is T = 3U/E solve for U

Answers

To solve for U in the equation T = 3U/E, you need to isolate U alone on one side of the equation. To do this, first multiply both sides of the equation by E, to get TE= 3U. Then divide both sides of the equation by 3 to get TE/3 = U. This provides the correct answer: U = TE/3.

249 is what percent of 300

Answers

Try using simple examples to help you get started e.g. 1 is how many percent of 2? You probably already know that it is 50%. You can use a formula to work this out (1/2)*100=50%. So you can use this information for your question:
(249/300)*100=83%
