WILL GIVE BRAINLIEST ASAP NEEDED PLS ANSWER HELPYou need to create a fenced Off region of Land for cattle to graze. The grazing area must be a total of 500 square feet surrounded by a fence and in the shape of a regular polygon within this grazing area the length of the apothem must be 10 feet long.

Part. 1 find the total perimeter of the grazing area
Part 2. if the cost of the fence is $7.95 per linear foot how much will it cost to place a fence around the entire grazing area?
Part 3 - suppose this grazing area is 1/60 of an industrial grazing area for major industry farm. What is the total cost to build a fence around the entire land of the large scaled farm

Answer 1

Answer:

Answer:

$47,520

Step-by-step explanation:

the area of a polygon is/

A= perimeter X apothem /2

A=500

apothem = 10

500 = (P * 10)/2

P =100

B. 100*7.95 = $795

60*100= 6,000

6,000 * $7.95=

$47,520

Therefore, 171 divided by 9 equals 19.

Note that division is a mathematical operation that involves dividing a number (the dividend) by another number (the divisor) to find the quotient.

The quotient represents the result or answer obtained from dividing the dividend into equal parts determined by the divisor.

A cow is tethered to one corner of a barn, 10 feet by 10 feet, with a rope 100 feet long. What is the cows maximum grazing area?

Answers

Question???? Is the cow inside or outside of the barn?

We'll assume it is outside the barn because the inside is too easy.

---------------------------------

First we have an area that is 3/4 of a circle with a radius of 100 ft.

area=(3.14*100^2)*3/4=(3.14*10,000)*3/4=31,400*3/4=23,550 ft^2.

now we have a quarter circle with a raduis of 90 ft.

area=(3.14*90^2)/4=(3.14*8,100)/4=25,434/4=6,358.5 ft^2.

as an esimate of the remaining 2 slivers of 5*80+5*90=400+450=950 ft^2 (minus a tad)

adding up these pieces I get 23,550+6,358.5+950=30,858.5 ft^2 (minus the tad)

The equation that models the height above or below equilibrium in inches, h, of a spring over time in seconds, t, is h = -15 cos(2pi/5 t). At which times will the spring be at a height of 8 in. above equilibrium? Select two of the following, make two selections.

Answers

Answer:

1.7 seconds, and

3.3 seconds

Step-by-step explanation:

We simply need to plug in 8 into h and solve for t:

$h=-15Cos((2\pi)/(5)t)\n8=-15Cos((2\pi)/(5)t)\n-(8)/(15)=Cos((2\pi)/(5)t)\n(2\pi)/(5)t=Cos^(-1)(-(8)/(15))\n(2\pi)/(5)t=2.13\nt=(2.13)/((2\pi)/(5))\nt=1.70$

Since cosine is negative in the 3rd quadrant as well, we need to figure out the 3rd quadrant equivalent of 2.13 radians.

First, π - 2.13 radians = 1.01 radians.

Then, we add 1.01 to π radians, so we get 4.15 radians

Solving from the last part, we have:

$t=(4.15)/((2\pi)/(5))\nt=3.3$

also, t = 3.30 seconds

*Note: we put the calculator mode in radians when solving

So, t = 1.7 seconds & 3.30 seconds
