In cirle O, OE = 12, what is the length of the circle's radius

1. What is the value of x? Show all of your work.

Colt1911 [192]

You can use the pathagorean theorm.
$a^2 + b^2 = c^2$
$a^2 + 6^2 = \sqrt{117}^2$
$a^2 + 36 = 117$
$a^2 = 117 - 36$
$a^2 = 81$
$\sqrt{a^2} = \sqrt{81}$
$a = 9$
x = 9

What fraction of an hour is 56 minutes? Give your answer in its simplest form.

d1i1m1o1n [39]

Answer:

$\frac{14}{15}$

Step-by-step explanation:

There are 60 minutes in an hour, thus

56 minutes = $\frac{56}{60}$ of an hour

To simplify divide 56 and 60 by 4

56 minutes = $\frac{14}{15}$ ← in simplest form

Please help me answer this question

avanturin [10]

By direct substitution and simplification, the trigonometric function z = cos (2 · x + 3 · y) represents a solution of the partial differential equation $\frac{\partial^{2} t}{\partial x^{2}} - \frac{\partial^{2} t}{\partial y^{2}} = 5\cdot z$ .

<h3>How to analyze a differential equation</h3>

Differential equations are expressions that involve derivatives. In this question we must prove that a given expression is a solution of a differential equation, that is, substituting the variables and see if the equivalence is conserved.

If we know that $z = \cos (2\cdot x + 3\cdot y)$ and $\frac{\partial^{2} t}{\partial x^{2}} - \frac{\partial^{2} t}{\partial y^{2}} = 5\cdot z$ , then we conclude that:

$\frac{\partial t}{\partial x} = -2\cdot \sin (2\cdot x + 3\cdot y)$

$\frac{\partial^{2} t}{\partial x^{2}} = - 4 \cdot \cos (2\cdot x + 3\cdot y)$

$\frac{\partial t}{\partial y} = - 3 \cdot \sin (2\cdot x + 3\cdot y)$

$\frac{\partial^{2} t}{\partial y^{2}} = - 9 \cdot \cos (2\cdot x + 3\cdot y)$

$- 4\cdot \cos (2\cdot x + 3\cdot y) + 9\cdot \cos (2\cdot x + 3\cdot y) = 5 \cdot \cos (2\cdot x + 3\cdot y) = 5\cdot z$

By direct substitution and simplification, the trigonometric function z = cos (2 · x + 3 · y) represents a solution of the partial differential equation $\frac{\partial^{2} t}{\partial x^{2}} - \frac{\partial^{2} t}{\partial y^{2}} = 5\cdot z$ .
