The Pythagorean identity is based from the three trigonometric identities that apply to the Pythagorean theorem. The three identities are founded on the concept that the hypotenuse is equal to the sum of the squares of the two sides of the right triangle. The identities can be determined through the substitution of sine and cosine in the right triangles measurements.

Emily and Andy each go to a hardware store to buy wire.The table shows the relationship between the cost and the length of wire.
Lady_Fox [76]

Answer:

So, Emily will spend,  11.52 unit on wire

and, Andy will spend  18.72 unit on wire.

Step-by-step explanation:

Cost of wire is = \frac {4.80}{120}

                       =  \frac {5.40}{135}

                       = \frac {6.00}{150}

                       = \frac {7.00}{175}  

                        = 0.04 unit/inch

We know that,

 12 inch = 1 foot    and

  1 yard = 3 foot    [Note that unit of a quantity always denoted singular].

So, Emily will spend,

  24 \times 12 \times 0.04 unit

 = 11.52 unit on wire

and, Andy will spend,

  13 \times 3 \times 12 \times 0.04 unit

 = 18.72 unit on wire.
