Jordan measures the side lengths of a triangular piece of sheet metal. the side lengths are 156 cm, 133cm, and 205 cm. verify that the triangular piece of sheet metal is a right triangle. (this problem involves polynomial identities)
as soon as possible,

see the explanation

Step-by-step explanation:

we know that

If the triangular piece of sheet metal is a right triangle, then the side lengths must satisfy the Pythagorean Theorem

so

where

c is the hypotenuse (the greater side)

a and b are the legs of triangle

we have

substitute

----> is true

so

The side lengths satisfy the Pythagorean Theorem

therefore

The triangular piece of sheet metal is a right triangle

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
