1 answer:
Tcecarenko [31]3 years ago

Answer:

For a 7 hectare plot, the radius is 149.3 m.

For a 12 hectare plot, the radius is 195.5 m.

For a 30 hectare plot, the radius is 309.1 m.

Step-by-step explanation:

For a circular plot of area A, the radius is

[tex]r=\sqrt{A/\pi}[\tex]

One hectare is equal to 10,000 m2.

For a 7 hectare plot, the radius is

[tex]r=\sqrt{7*10,000/3.14}\\r=\sqrt{22,293}=149.3[\tex]

For a 12 hectare plot, the radius is

[tex]r=\sqrt{12*10,000/3.14}\\r=\sqrt{38,216}=195.5[\tex]

For a 30 hectare plot, the radius is

[tex]r=\sqrt{30*10,000/3.14}\\r=\sqrt{95,541}=309.1[\tex]

If anyone can answer this, I will give you hearts!

Answer:

  see attached

Step-by-step explanation:

Rotation 270° counterclockwise is equivalent to rotation 90° clockwise. The transformation of coordinates is ...

  (x, y) ⇒ (y, -x) . . . . . . . rotation 270° CCW

This means the points are moved to ...

  A(-2, 1) ⇒ A'(1, 2)

  B( 1, 2) ⇒ B'(2, -1)

  C(-2, 4) ⇒ C'(4, 2)

The rotated triangle is shown in the attachment. You may notice that A' and B are the same point.

If the product of the integers a, b, and c is 1, then what is the difference between the largest and the smallest possible
stepladder [879]
Since there are no multiples other than 1 and -1 that could multiply in any way to equal 1, those are the only numbers you can really work with

it is a possibility that a, b, and c could equal 1 but then it would go wrong when comes time to subtract since all numbers are equal and cannot subtract largest from smallest.

a logical approach would be to try -1, -1, and 1 since -1 * -1 = 1 and then 1* 1 =1

we can make a= -1 , b= -1, and c= 1
 (we need b to equal -1 so that we get an answer of -1 opposed to if we made a=-1 and c=-1, all outcomes would equal 1)
-1²=1
-1³=-1
1⁴= 1
since 1 is the largest possible outcome and -1 is the lowest possible outcome you should subtract the two

1-(-1) = 1+1 = 2

The answer should be D: 2

Can someone help me please
nataly862011 [7]

Answer:

D is 90 E is 81 F is 99

Step-by-step explanation:

D is 90 because a straight angle equals 180 degrees. E is 81 because it is directly across from 81. F is 99 because 180-81 is 99
