Simon put $15000 in an account with a simple interest rate of 4.5%. How much interest will be earned after 8 years?

Leto [7]

$~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$15000\\ r=rate\to 4.5\%\to \frac{4.5}{100}\dotfill &0.045\\ t=years\dotfill &8 \end{cases} \\\\\\ I = (15000)(0.045)(8)\implies I=5400$

Use the function below to find f(1). f9t0=4

ExtremeBDS [4]

The value of the F(1) is 1/2 option (C) is correct after plugging the value of t = 1 in the provided function.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The complete question is attached in the picture please refer to the picture.

We have a function:

$\rm F(t) = 4\dfrac{1}{2^{3t}}$

Plug t = 1

$\rm F(1) = 4\dfrac{1}{2^{3\times1}}$

After solving:

F(1) = 1/2

Thus, the value of the F(1) is 1/2 option (C) is correct after plugging the value of t = 1 in the provided function.

If 1-cos A=1/2 then find the value of sinA.

Aneli [31]

Step-by-step explanation:

$1 - \cos( \alpha ) = \frac{1}{2} \\ = > \cos( \alpha ) = 1 - \frac{1}{2} = \frac{1}{2} \\ = > \alpha = arccos( \frac{1}{2} ) =60 {}^{ \bullet} = \frac{\pi}{3} \\ then \\ \sin( \frac{\pi}{3} ) = \frac{ \sqrt{3} }{2}$

ZX is √b²+a²

Step-by-step explanation:

From the diagram you notice that length WX is a and length WZ is b.ZX is the diagonal length formed by triangle ZWX.Apply the Pythagorean relationship here the sum of squares of the two sides equals the square of the diagonal.Hence;

ZW²+ WX²=ZX²

b²+a²=ZX²

√b²+a²=ZX
