Question one

farmer jones has 140 feet of fencing to construct a rectangular corral.

if x represents the width of the corral, which function can be used to express the area a of the

corral as a function of x?

a

a(x) = 70.0

b

a(z) = 2(70 - 2)

c

a(x) = a(140 – 2)

d

a(z) = x(140 – 22)

Step-by-step explanation:

Let

x ----> the width of the rectangular corral

y ----> the length of the rectangular corral

we know that

The perimeter of the rectangular corral is equal to

so

simplify

----> equation A

Remember that

The area of a rectangle is equal to

----> equation B

substitute equation A in equation B

Convert to function notation

your answer would be 10x - 1

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
