A rectangular field is fully enclosed with 218 meters of fencing. The length of the field is
mestny [16]

The length and width of a rectangular field fully enclosed with 218 metes fencing  are 63 meters and 46 meters respectively.

The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:

  • perimeter = 2(l + w)

where

l = length

w = width

perimeter = 218 meters

The length of the field is  17 meters longer than the width, w. Therefore, the length is defined as follows:

  • l = 17 + w

The length and the width can be calculated as follows:

218 = 2(l + w)

218 = 2(17 + w + w)

218 = 34 + 4w

218 - 34 = 4w

184 = 4w

divide both sides by 4

w = 184 / 4

w = 46 meters

length = 17 + 46

length = 63 meters

Write a function based on the given parent function and transformations in the given order
kondaur [170]

Answer:

y=-\left(x-2\right)^{2}-4 is the resultant function after transformations.

Step-by-step explanation:

Parent function is given as:

y=x^2 (Graph 1 in attachments, it is a parabola)

Let us apply the transformations step by step:

<u>1. Shift 2 units to the right </u>i.e.

change the value of x by 2.

The equation of a parabola can be: y=(x-a)^2 where a is the point on x axis which is the axis of symmetry.

Right side means the equation becomes:

y=(x-2)^2  (Graph 2 in attachments)

<u>2. Reflect over x axis</u> i.e.

change the sign of y from + to -.

y=-(x-2)^2 (Graph 3 in attachments)

3. <u>Shift downward 4 units </u> i.e.

Subtract 4 from the value of y:

y=-(x-2)^2-4 (Graph 4 in attachments)

Find the exact length of the third side
Mumz [18]

Answer:

5

Step-by-step explanation:

We know that 13 is the hypotenuse. With this we can use the Pythagorean Theorem to solve this problem.

Let the third side be x.

13^2=12^2+x^2

169=144+x^2

169-144=x^2

25=x^2

x=5

Solved.
