Answer:

There will be 7 students on each bus.

Step-by-step explanation:

If the class of 63 students is divided into 9 buses with the same number of students traveling in each one, to determine the number of students traveling in each bus it is necessary to perform the following mathematical calculation:

63/9 = X

7 = X

Thus, in each bus 7 students will travel, and in this way all buses will carry the same number of students.

When a figure is translated on a coordinate grid, what conclusion can you draw from the pre-image and image? The orientation cha
blagie [28]
The correct answer is -The position changes, and the angles remain congruent. or C.

The size does not change because the shape is only moving to new coordinates not growing or shrinking.
This means the shape also does not change.
When you translate a shape in geometry it means you are changing the position. But the shape will remain the same, meaning the angles remain congruent.

Consider the following initial-value problem. Y'' − 5y' = 8e4t − 4e−t, y(0) = 1, y'(0) = −1 find ℒ{f(t)}, for f(t) = 8e4t − 4e−t

The <em>Laplace</em> transform of the <em>non-homogeneous second order differential</em> equation is \mathcal {L} \{f(t)\} = \frac{4\cdot (s+6)}{s\cdot (s-4)\cdot (s+1)\cdot (s-5)} +\frac{1}{s} -\frac{1}{s\cdot (s-5)}.

<h3>How to determine the Laplace transform of a non-homogeneous second order differential equation </h3>

A <em>Laplace</em> transform is a <em>frequency-based algebraic</em> substitution method used to determine the solutions of <em>differential</em> equations in a quick and efficient manner.

In this question we shall use the following <em>Laplace</em> transforms:

\mathcal {L} \{f(t) + g(t)\} = \mathcal {L} \{f(t)\} + \mathcal {L}\{g(t)\}   (1)

\mathcal {L} \{\alpha\cdot f(t)\} = \alpha\cdot \mathcal {L} \{f(t)\}   (2)

\mathcal{L} \left\{y^{(n)} \right\} = s^{n}\cdot \matcal {L}\{f(t)\}-s^{n-1}\cdot y(0) -...-y^{(n)}(0)   (3)

\mathcal {L} \{e^{-a\cdot t}\} = \frac{1}{s+a}   (4)

Now we proceed to derive an expression fo the <em>Laplace</em> transform of the solution of the <em>differential</em> equation:

y'' -5\cdot y' = 8\cdot e^{4\cdot t}-4\cdot e^{-t}

s^{2}\cdot \mathcal {L}\{f(t)\}-5\cdot y(0) - y'(0) - 5\cdot s \cdot \mathcal {L} \{f(t)\} +5\cdot y(0) = \frac{8}{s-4}-\frac{4}{s+1}

\mathcal {L} \{f(t)\} = \frac{4\cdot (s+6)}{s\cdot (s-4)\cdot (s+1)\cdot (s-5)} +\frac{1}{s} -\frac{1}{s\cdot (s-5)}

The <em>Laplace</em> transform of the <em>non-homogeneous second order differential</em> equation is \mathcal {L} \{f(t)\} = \frac{4\cdot (s+6)}{s\cdot (s-4)\cdot (s+1)\cdot (s-5)} +\frac{1}{s} -\frac{1}{s\cdot (s-5)}. \blacksquare
