My name is Ann [436]

Answer:

<u>Solutions given;</u>

<u>Using cosine rule</u>

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b=\sqrt{102.48}

b=10.12

b=10.1

<u>Using sine rule</u>

\frac{sin A}{BC} = \frac{sin B}{AC}  =\frac{sin C}{AB}

\frac{sin 29°}{15}  =\frac{sin C}{8}

<u>Doing criss cross multiplication</u>

Sin C=\frac{sin 29°}{15} ×8

m<C=Sin -¹(0.29)

m<C=14.98

<u>m<C=15°</u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>

Jacob wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence
Citrus2011 [14]

Jacob wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn,so he needs no fence on that side.

Let w be the width of the enclosure (perpendicular to the barn) and let l be the length of the enclosure (parallel to the barn).

one side of the length is not counted for perimeter because one side of length will be against the barn.

Perimeter = 400 ft

Perimeter of rectangle = L + W + W

400 = L + 2W

L = 400 - 2W

Area = L * W

Replace L by  400 - 2W

A(W) =  (400 - 2W) * W

A(W) = -2W^2 + 400W

Now we find out x coordinate of vertex to find the width that maximize the area

W = \frac{-b}{2a}

a= -2 and b = 400

W = \frac{-(400)}{2(-2)}=100

The width  w would maximize the area is w = 100ft

To find maximum area we plug in 100 for W in A(W)

A(W) = -2W^2 + 400W

A(W) = -2(100)^2 + 400(100)= 20000

the maximum area is 20,000 square feet
