Answer:

√194 or 13.9

Step-by-step explanation:

√(x2 - x1)² + (y2 - y1)²

√[-2 - (-7)² + [4 - (-9)]

√(5)² + (13)²

√25 + 169

√194

= 13.9

Eduardwww [97]

Answer: 2.8 hours (equivalent to 2 hrs, 48 min)

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

Work Shown:

Multiply 0.35 by 8 and you'll get 2.8, which breaks down as follows

2.8 hrs = (2 hrs) + (0.8 hrs)

2.8 hrs = (2 hrs) + (0.8 hrs)*(60 min/1 hr)

2.8 hrs = (2 hrs) + (0.8*60 min)

2.8 hrs = (2 hrs) + (48 min)

2.8 hrs = 2 hrs, 48 min

A farmer wants to fence a rectangular garden next to his house which forms the northern boundary. The fencingfor the southern bo

Answer:

10 ft x 10 ft

Area = 100 ft^2

Step-by-step explanation:

Let 'S' be the length of the southern boundary fence and 'W' the length of the eastern and western sides of the fence.

The total area is given by:

$A=S*W$

The cost function is given by:

$\$ 120 = \$3*2W+\$6*S\\20 = W+S\\W = 20-S$

Replacing that relationship into the Area function and finding its derivate, we can find the value of 'S' for which the area is maximized when the derivate equals zero:

$A=S*(20-S)\\A=20S-S^2\\\frac{dA}{dS} = \frac{d(20S-S^2)}{dS}\\0= 20-2S\\S=10$

If S=10 then W =20 -10 = 10

Therefore, the largest area enclosed by the fence is:

$A=S*W\\A=10*10 = 100\ ft^2$
