The owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway. If s
navik [9.2K]

Answer:

Step-by-step explanation:

Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.

Fencing is used for 2times length and 1 width if highway side is taken as width

So we have 2l+w = 2900

Or w = 2900-2l

Area of the rectangular region = lw

A(l) = l(2900-2l) = 2900l-2l^2\\

Use derivative test to find the maximum

A'(l) = 2900-4l\\A"(l) = -4

So maximum when I derivative =0

i.e when l =\frac{2900}{4} =725

Largest area = A(725)

= 725(2900-2*725)\\= 1051250

1051250 sqm is area maximum

PLEASE HELPP!!!!!<br>what is the slope of the line?<br><br>-3<br><br>1<br><br>0<br><br>undefined
marysya [2.9K]
Answer: -4

The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.

Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.

rise/run

4/run

Left and right, the difference is only one unit.

4/run

4/1

4

This graph is also negative, so let’s add that in.

-4

This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.

Hope this helps comment below for more questions :)
