Find the charge $q (t)$ flowing through a device if the current is:
(a) $i (t) = 3 A, q (0) = 1 C,$
(b) $i (t) = (2 t + 5) m A, q (0) = 0$
(c) $i (t) = 20 c o s (10 t + π / 6) μ A, q (0) = 2 μ C$
(d) $i (t) = 10 e^{- 30 t} \sin 40 t A, q (0) = 0$

Find a k such that the product of the first k 's, plus 1, is not ', but has a ' factor larger than any of the first k 's. (There is no trick for solving this. You just have to try various possibilities!)

The Gompertz model has been used to model population growth.
$\frac{d y}{d t} = r y \ln (\frac{K}{y}),$
where $r = 0.73 p e r y e a r, k = 33, 800 k g, \frac{y_{0}}{k} = 0.27$ Use the Gompertz model to find the predicted value of y(3)Round your answer to the nearest integer

Let S be the set of all strings of 0’s and 1’s, and define $D : S \Rightarrow Z$ as follows: For all $S \in S$ , $D (s) =$ the number of 1’s in s minus the number of 0’s in s.
a. Is D one-to-one? Prove or give a counterexample.
b. Is D onto? Prove or give a counterexample.

This formula describes the multiplication rule for finite summation. $(\sum_{k = 0}^{n} a_{k}) \sum_{j = 0}^{n} b_{j} = \sum_{k = 0}^{n} \sum_{j = 0}^{n} a_{k} b_{j}$
This formula is called Langrange's identity.
${(\sum_{k = 1}^{n} a_{k} b_{k})}^{2} = (\sum_{k = 1}^{n} a_{k}^{2}) \sum_{k = 1}^{n} b_{k}^{2} - \sum_{k = 1}^{n} \sum_{j = K + 1}^{n} {(a_{k} b_{j} - a_{j} b_{k})}^{2}$
Explain the difference between these two summation rules. Why is the product of two sums a double row and the square of the sum is a double row? Why does the square intersect the terms but not the product? Provide proof.

If s is a string, define its reverse $s^{R}$ as follows.
$\begin{array}{cc} B . & λ^{R} = λ \\ R . & If s has one or more symbols, write \\ s = r a \\ where a is a symbol and r is a string (possibly empty). Then \\ s^{R} = (r a)^{R} = a r^{R} . \end{array}$
Compute ${(c u b s)}^{R}$ . Justify each step using the definition.

2 points) Page Turner loves discrete mathematics. She has 8 ''graph theory'' books, 6 books about combinatorics, and 4 ''set theory'' books.
How many ways can she place her discrete mathematics books on the same shelf in a row if:
a) there are no restrictions.
b) graph theory books are next to each other but the others could be anywhere on the shelf.
c) books are organized by their topic (same kinds are next to each other).

Let f(n) be the largest ' divisor of n. Can it happen that x < y but f(x) > f(y)?Give an example or explain why it is possible.

Students pursuing advanced Math are constantly dealing with advanced Math equations that are mostly used in space engineering, programming, and construction of AI-based solutions that we can see daily as we are turning to automation that helps us to find the answers to our challenges. If it sounds overly complex with subjects like exponential growth and decay, don’t let advanced math problems frighten you because these must be approached through the lens of advanced Math questions and answers. Regardless if you are dealing with simple equations or more complex ones, just break things down into several chunks as it will help you to find the answers.
