\bf \qquad \textit{Simple Interest Earned}\\\\
A = Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\to 1000000\\
P=\textit{original amount deposited}\to& \$1300\\
r=rate\to 17\%\to \frac{17}{100}\to &0.017\\
t=years
\end{cases}

\bf 1000000=1300e^{0.17t}\implies \cfrac{1000000}{1300}=e^{0.17t}\implies \cfrac{10000}{13}=e^{0.17t}
\\\\\\
ln\left( \frac{1000000}{1300} \right)=ln(e^{0.17t})\implies ln\left( \frac{1000000}{1300} \right)=0.17t
\\\\\\
\cfrac{ln\left( \frac{1000000}{1300} \right)}{0.17}=t\impliedby years

now, how many days? simply multiply t * 365.

Find a function f whose graph is a parabola with the given vertex and that passes through the given point.
goblinko [34]

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

A parabola equation is what is it?

A parabola's general equation is written as y = a(x - h)2 + k or x = a(y - k)2 + h.

To determine the equation of a parabola, we can utilize the vertex form. Assuming we can read the coordinates (h,k) from the graph, the aim is to utilize the coordinates of its vertex (maximum point, or minimum point), to formulate its equation in the form y=a(xh)2+k, and then to determine the value of the coefficient a.

Find the equation of the line passing through (1,4) and (-2,-1).
wel

Answer:

y=5/3x+7/3

Step-by-step explanation:

Here are the points: (1,4) and (-2, -1)

let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)

label the points:

x1=1

y1=4

x2=-2

y2=-1

now subsitute into the equation

m=(-1-4)/(-2-1)

m=-5/-3

m=5/3

the slope of the line 5/3

Here's the equation so far:

y=5/3x+b (b is a place holder)

we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>

let's use (1,4) as an example

4=5/3(1)+b

4=5/3+b

subtract 5/3 from both sides

7/3=b

Now, put it all together:

y=5/3x+7/3

Hope this helps!
