Suppose you invest $400 at an annual interest rate 7.6% compounded continuously. How much will you have in the account after 1.5

goldfiish [28.3K]

$\bf ~~~~~~ \textit{Continuously Compounding Interest Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$400\\
r=rate\to 7.6\%\to \frac{7.6}{100}\to &0.076\\
t=years\to &1.5
\end{cases}
\\\\\\
A=400e^{0.076\cdot 1.5}\implies A=400e^{0.114}$

find the curved surface area and total surface area of a right circular cylinder whose height is 15 cm and radius of the base is

ki77a [65]

Answer:

$CSA = 660cm^2$ --- Curved Surface Area

$TSA = 968cm^2$ --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

$h = 15$ -- height

$r = 7$ --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

$CSA = 2\pi rh$

This gives:

$CSA = 2 * \frac{22}{7} * 7 * 15$

$CSA = 2 * 22* 15$

$CSA = 660cm^2$

Solving (b): The total surface area (TSA)

This is calculated as:

$TSA = 2\pi r(h + r)$

This gives:

$TSA = 2 * \frac{22}{7} * 7 * (15 + 7)$

$TSA = 2 * 22 * (15 + 7)$

$TSA = 2 * 22 * 22$

$TSA = 968cm^2$

I get see photo. I l ow this is wrong. Can you help?

mylen [45]

Given the equation:

$y=x^2+x-4$

We will find the value of (y) when ( x = 2i )

Note: i² = -1

so, when x = 2i

$y=(2i)^2+(2i)-4$

Simplifying the answer

So,

$\begin{gathered} y=4i^2+2i-4 \\ y=4\cdot(-1)+2i-4 \\ y=-4+2i-4 \\ y=-8+2i \end{gathered}$

So, the answer will be y = -8+2i
