Answer:

10

Step-by-step explanation:

( - 1, - 2 )

Let,

x1 = - 1

y1 = - 2

( - 9, 4 )

Let,

x2 = - 9

y2 = 4

Formula : -

Distance = √ [ ( x1 - x2 )² + ( y1 - y2 )² ]

Distance = √ [ ( - 1 - ( - 9 ) )² + ( - 2 - 4 )² ]

               = √ [ ( - 1 + 9 )² + ( - 6 )² ]

               = √ [ 8² + ( - 6 )² ]

               = √ [ 64 + 36 ]

               = √100

Distance = 10

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a​ single-strand electric
larisa86 [58]

Answer:

525 x 1,050

A = 551,250 m²

Step-by-step explanation:

Let 'L' be the length parallel to the river and 'S' be the length of each of the other two sides.

The length of  the three sides is given by:

2S+L=2,100\\ L=2100-2S

The area of the rectangular plot is given by:

A=S*L\\A=S(2100-2S)\\A=2100 S -2S^2

The value of 'S' for which the area's derivate is zero, yields the maximum total area:

\frac{dA(S)}{dS}=\frac{d(2100 S -2S^2)}{dS}\\0= 2100 - 4S\\S=525

Solving for 'L':

L=2100-(2*525)\\L=1,050

The largest area enclosed is given by dimension of 525 m x 1,050 and is:

A = 525*1,025\\A=551,250\ m^2

A subtending arc on a circle with a radius of 4.5 centimeters has an arc length of 8π. The measure of the angle subtended by the
ella [17]
For the answer to the question above, 

<span>the angle of 360 ° → π.d </span>

<span>the angle of x ° → 8π </span>


<span>You make the cross-multiply and you can get: </span>

<span>x * π.d = 8π * 360 </span>

<span>x * d = 8 * 360 </span>

<span>x = 8 * 360/d → where d = 2r </span>

<span>x = 8 * 360/2r </span>

<span>x = 4 * 360/r → where r = 4.5 cm </span>

<span>x = 4 * 360/4.5 </span>

<span>x = 320 °</span>

I know it is a long question but please I will mark brainlist to the person who answers please help
Diano4ka-milaya [45]

Answer:

Carla lives 16 miles from the Library.

The mistake is drawng the diagram incorrectly and using the miles given in the wrong places. The <u>student's</u> diagram has Yuri in a place that's Southwest of the Library in the diagram given

Step-by-step explanation:

If Yuri lives 24 miles SOUTH of the library, the "b" side of the triangle should be 24, with the Library at the top and Yuri at the bottom left, which is the west end of the base. The base "a" of the triangle should extend 10 to the right (East in compas directions) forming the right angle. Carla lives at the sharp southeast corner of the triangle, and the Hypotenuse "c"  from her house to the Library is the distance we have to figure.

c² =a² + b²

c² = 10² + 24²

c² = 100 + 576

c² = 676

√c² = √676

c = 26       Carla lives 26 miles from the Library.
