A gardener uses 144 feet of fencing to build a rectangular garden. The function A(w)=24w−w2 can be used to find the area of the
levacccp [35]

Answer:

The graph of the equation is shown in the picture attached below.

We can see w = 12 corresponds to the global maximum of the function, and for any w greater than 12 the value of A(w) decreases.

This means that for any value of the width greater than 12, the function cannot model the situation.

Making the equation only valid for

w ∈ [0,12]

Explain why the mean without the outliner could be a better description of the data set than the mean with the outliner.
lions [1.4K]
Sometimes the outlier, if it's too large, can throw off the mean, making it larger and smaller, so it isn't as accurate

sorry if this doesnt make sense if you need me to explain it more I will

Dani uses the table to help her convert measurements when she is sewing
Aleks [24]
The first thing we should do is see what relationship we have:
 Table is feet to yards 3-1
 a. Describe the relationship between the number of feet and the number of yards
 That is to say:
 1Yarda = 3 feet
 b. Write an expression for the number of yards in f feet
 Let
 y = Yard
 f = feet
 We have the following expression for the conversion:
 y = (1/3) f
 c. Find the number of yards in 63 feet 
 For this case we must substitute in the expression found the value of f = 63.
 y = (1/3) f
 y = (1/3) (63)
 y = 21
 answer:
 1Yarda = 3 feet
 y = (1/3) f
 y = 21
