Suppose that $2000 is invested at a rate of 3.4% compounded quarterly. Assuming that no withdrawals are made, find the total amount after 4 years. Do not round any intermediate computations and round your answer to the nearest cent.
Given data:
The amount invested ( principal) is
[tex]P=\text{ \$2,000}[/tex]The interest rate given is
[tex]r=3.4\%[/tex]The number of years is
[tex]t=4\text{ years}[/tex]The number of times compounded is quarterly
A quarterly event happens four times a year, at intervals of three months.
[tex]n=4[/tex]Concept:
The formula to calculate the amount compounded is given below as
[tex]\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \text{Where,} \\ A=\text{amount} \\ P=\text{principal} \\ r=\text{rate} \\ n=\text{ number of times compounded} \\ t=\text{ number of years} \end{gathered}[/tex]By substituting the values above in the formula, we will have
[tex]\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ A=2,000(1+\frac{3.4}{400})^{4\times4} \end{gathered}[/tex]By solving the equation above, we will have
[tex]\begin{gathered} A=2,000(1+\frac{3.4}{400})^{4\times4} \\ A=2,000(1+0.0085)^{16} \\ A=2000(1.0085)^{16} \\ A=2,290.05 \end{gathered}[/tex]Hence,
The final answer = $2,290.05

Answer:
[tex]\large\text{$y& = e^{\frac{1}{3}x^3+x+\text{C}}$}[/tex]
Step-by-step explanation:
Given differential equation:
[tex]\dfrac{\text{d}x}{\text{d}y}=\dfrac{1}{y(x^2+1)}[/tex]
Rearrange the equation so that all the terms containing y are on the left side, and all the terms containing x are on the right side:
[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}y}&=\dfrac{1}{y(x^2+1)}\\\\(x^2+1)\;\dfrac{\text{d}x}{\text{d}y}&=\dfrac{1}{y}\\\\(x^2+1)\;\text{d}x}&=\dfrac{1}{y}\;\text{d}y\\\\\dfrac{1}{y}\;\text{d}y&=(x^2+1)\;\text{d}x}\end{aligned}[/tex]
Integrate both sides:
[tex]\begin{aligned}\implies \displaystyle \int \dfrac{1}{y}\;\text{d}y &= \int (x^2+1)\;\text{d}x}\\\\\int \dfrac{1}{y}\;\text{d}y &= \int x^2\;\text{d}x}+\int 1\;\text{d}x}\\\\\ln y & = \dfrac{1}{3}x^3+x+\text{C}\\\\e^{\ln y} & = e^{\frac{1}{3}x^3+x+\text{C}}\\\\y& = e^{\frac{1}{3}x^3+x+\text{C}}\\\\\end{aligned}[/tex]
Therefore, the solution to the given differential equation is:
[tex]\large\text{$y& = e^{\frac{1}{3}x^3+x+\text{C}}$}[/tex]
Integration rules used:
[tex]\boxed{\begin{minipage}{3.5 cm}\underline{Integrating $\frac{1}{x}$}\\\\$\displaystyle \int \dfrac{1}{x}\:\text{d}x=\ln |x|+\text{C}$\end{minipage}}[/tex]

(a) The area of the triangle = 6 cm squares
(b) The area of the whole shape = 76 cm squares
The shape given is formed by a triangle and a rectangle.
First we need to find the area of the triangle.
Height of the triangle = 3 cm
Base of the triangle = 4 cm
Area of the triangle = 1/2 x base x height
= 1/2 x 4 x 3
= 6 cm squares
Area of the whole shape = Area of the triangle + Area of the rectangle
Length of the rectangle = 10 cm
Width of the rectangle = 7 cm
Area of the rectangle = length x width
= 10 x 7
= 70 cm squares
Therefore, area of the whole shape = 6 + 70
= 76 cm squares

Find an exponential equation that passes through the points (2,1.8) and (5,14.4) .
An exponential equation that passes through the points (2,1.8) and (5,14.4) is y = (0.6708)2ˣ
Exponential equation:
If you have two points, (x1, y1) and (x2, y2), you can define the exponential function that passes through these points by substituting them in the equation
y = abˣ
and solving for a and b.
In general, you have to solve this pair of equations:
y1 = abˣ¹ and y2 = abˣ²
Given,
The points (2,1.8) and (5,14.4).
Here we need to find the exponential equation that passes through the points.
This yields the following pair of equations:
1.8 = ab²
14.4 = ab⁵
If you divide the second equation by the first, you get
b³ = 14.4/1.8
b³ = 8
b = ∛8
b = 2
so b = 2. It's possible for b to also be equal to -2, but in this case, assume it's positive.
Now, we can substitute this value for b in either equation to get a. It's easier to use the first equation, so:
1.8 = a² x (2)²
1.8 = a² x 4
a² = 1.8/4
a² = 0.45
a = √0.45
a = 0.6708
Therefore, the exponential form of the equation is,
y = (0.6708)2ˣ

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions. The word equation and its cognates can have slightly different meanings in different languages. For instance, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign, whereas in French, an equation is defined as containing one or more variables.
The equation's solutions are the values of the unknown variables that satisfy the equality, which are often referred to as the variables for which the equation must be solved.

Simplifying the given equation we get :
5 (x + 3) = 9x - 13
5x + 15 = 9x - 13
