Jack and Andrea want to create a right triangle together using values of sand y and the polynomial identity to generate
koban [17]

Answer:

A right triangle can be considered as a special type because the relationship of its sides can be described using the hypotenuse formula: c^2 = a^2 + b^2 or c^2 = x^2 + y^2 where, c is the hypotenuse of the triangle and is the side opposite to the 90° angle while a and b are the sides adjacent to the 90° angle.

In the problem statement, we are given that one of the side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating for y: y^2 = c^2 – x^2 y^2 = 5^2 – 2^2 y^2 = 21 y = 4.58

Explanation:

The natural number is the number before the decimal. Therefore the answer is: y = 4

What types of orbital overlap occur in cumulene? check all that apply. hints check all that apply. p/p overlap s/sp2 overlap s/s
topjm [15]
<span>Answer: The carbons on the closures are sp² hybridized, with a p-orbital for the 'second' bond in the twofold bond with their neighboring carbons. They have those sp² orbitals covering with the s from the hydrogen, and they have a p covering in the pi bond with the neighboring carbon. They likewise have a sigma bond with the neighboring carbon I'll get to. The center carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (What's more, they likewise have p/p in the pi bonds). So the total list is: s/sp² p/p sp/sp² sp/sp</span>
