The diagonal length of a rectangular playing field is 76 feet, and its width is 48 feet. How long is the playing field?

Sauron [17]

The length of playing field is 58.9 feet

Solution:

Given that, the diagonal length of a rectangular playing field is 76 feet,

And its width is 48 feet.

To find: length of playing field

Now, we know that, diagonal, width and length of a rectangle will form an right angle triangle with diagonal as hypotenuse.

So, now, in a right angled triangle we can use pythagorean theorem to find the length

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above definition, In a right angled triangle ABC we get

$c^2 = a^2 + b^2$

Where "c" is the length of hypotenuse

"a" is the length of one leg of right angled triangle

"b" is the length of other leg of right angled triangle

$\begin{array}{l}{\text {Then, diagonal = width }^{2}+\text { length }^{2}} \\\\ {76^{2}=48^{2}+\text {length }^{2}} \\\\ {\text {Length }^{2}=76^{2}-48^{2}} \\\\ {\text {Length }^{2}=5776-2304}\end{array}$

$\begin{array}{l}{\text { Length }^{2}=3472} \\\\ {\text { Length }=\sqrt{3472}} \\\\ {\text { Length }=58.92}\end{array}$

Hence, the length of the rectangular field is 58.9 feet

FILL IN THE BLANKS: Given P(x) = 3x5 + 7x6 + 11x7 – 12x - 10

Mama L [17]

The polynomial $3x^5 + 7x^6 + 11x^7 - 12x - 10$ is in standard form if the exponents are arranged in decreasing order.

<h3>Polynomial in Standard Form</h3>

Polynomial is an algebraic expression with one or more terms. For example : $2x^3+6x^4+x^2+x+2$ . In this example and in your exercise the exponents of the terms are not arranged in order.

Um polynomial is in Standard Form when the exponents of the terms are in decreasing order. See more details below.

$2x^3+6x^4+x^2+x+2$ is not in standard form because the exponents are not written in decreasing order.

$6x^4+2x^3++x^2+x+2$ is in standard form because the exponents are written in decreasing order.

Therefore, the given polynomial will be in standard form if yours exponents are arranged in decreasing order.
