Answer:
x = 3
Step-by-step explanation:
Given
4 : 8 = x : 6, expressing in ratio form, that is
=
( cross- multiply )
8x = 24 ( divide both sides by 8 )
x = 3
Thus 4 : 8 = 3 : 6
The complete question is
"Find the general solution of the given differential equation
y''-y=0, y1(t)=e^t , y2(t)=cosht
The function
is the solution of the given differential equation.
The function y(t)=cosht is the solution of given differential equation.
<h3>What is a function?</h3>
The function is a type of relation, or rule, that maps one input to specific single output.
Given;
![y_1(t) = e^t](https://tex.z-dn.net/?f=y_1%28t%29%20%3D%20e%5Et)
Given differential equations are,
y''-y = 0
So that,
Substitute values in the given differential equation.
![e^t -e^t=0](https://tex.z-dn.net/?f=e%5Et%20-e%5Et%3D0)
Therefore, the function
is the solution of the given differential equation.
Another function;
So that,
![y"(t)=sinht\\\\y"(t)=cosht](https://tex.z-dn.net/?f=y%22%28t%29%3Dsinht%5C%5C%5C%5Cy%22%28t%29%3Dcosht)
Hence, function y(t)=cosht is solution of given differential equation.

Answer: 2/3
Step-by-step explanation: You take the 2 and divided it by 3 but your going to get a long decimal so you can put it into a fraction of 2/3
For a regular polygon with n sides, interior angle
= [(n-2) × 180°]/n
So, interior angle of this regular heptagon shape
= [(7 - 2) × 180°]/7
= (5 × 180°)/7
= 900°/7
= (900/7)°
= 128.571° [approximately]
