The nose of the origami dog is a right angle with sides that are 2 cm, 3 cm, and 3.6 cm long. What is the area of this triangle?
Maslowich

Given:

The sides of a right triangle are 2 cm, 3 cm, and 3.6 cm.

To find:

The area of the right triangle.

Solution:

Area of a triangle is:

Area=\dfrac{1}{2}\times base\times height

In the given triangle 3.6 cm is the largest side, it means 3.6 cm is the length of the hypotenuse. So, 2 cm and 3 cm and the base and height of the triangle.

Now, the area of the given triangle is:

Area=\dfrac{1}{2}\times 2\times 3

Area=3

Therefore, the area of the given triangle is 3 square cm.

A farmer wants to fence in a rectangular plot of land adjacent to the north wall of his barn. No fencing is needed along the bar
san4es73 [151]

Answer:

x = 125 ft and y = 250/3 ft

Step-by-step explanation:

Let assume that,

x be the length of the northern part of the fence (parallel to the north wall)

y be the length of the western and eastern pieces of the fence

As well as farmer has $4000 to spend hence we can write,

8x + 8y + 4y = 4000

8x + 12y = 4000

Hence we can say that,

from the above equation we can write

y=\frac{4000}{12} -\frac{2x}{3}

We know that area

A=xy.

A(x) =\frac{500x}{3}-\frac{2x^2}{3}

we can write

A'(x) = \frac{500}{3} -\frac{4x}{3}

equating it 0 we get

A'(x) = \frac{500}{3} -\frac{4x}{3}=0

x=125

Also,

A"(x) = -\frac{4}{3}

which is less than zero.

we can see that A''(x) is always less than 0 hence using second derivative test we can say that x = 125 is a maximum point.

now, solving for y we get  y= \frac{250}{3}

Hence we can say that dimensions for the plot that would enclose the most area is,

x = 125 ft and y = 250/3 ft
