After 5 years, Rachel’s amount in her savings account is $7446.52. Her account earned interest at 4.32% APR and was compounded d

Katyanochek1 [597]

$\bf \qquad \textit{Continuously Compounding Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &7446.52\\
P=\textit{original amount deposited}\\
r=rate\to 4.32\%\to \frac{4.32}{100}\to &0.0432\\
t=years\to &5
\end{cases}
\\\\\\
7446.52=Pe^{0.0432\cdot 5}\implies \cfrac{7446.52}{e^{0.0432\cdot 5}}=P\implies 5999.92404\approx P$

If you are given the graph of g (x) = log Subscript 2 Baseline x, how could you graph f (x) = log Subscript 2 Baseline x + 5?

olganol [36]

<h3>Answer: Shift the graph of g(x) up 5 units</h3>

Reasoning:

$g(x) = \log_2(x)$

$f(x) = \log_2(x)+5$

We see that f(x) = g(x)+5. Whatever the output of g(x) is, we add on 5 to get the output of f(x). The input is x, while the output is y. Adding 5 to the y output is what shifts every point on g(x) up 5 units to move the entire curve up 5 units.

Find the equation of the straight line passing through the point (3, 3) which is perpendicular to the line y=-x-4

Elena L [17]

Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x

Write an equation for the line that passes through (0, -9) and (3, 0).

MAXImum [283]

First find the slope of the line:-

= (0- - 9) / (3 - 0) = 9/3 = 3

Now use the point slope form of the equation to plug in the point (3,0):-
y - y1 = 3(x - x1)
y1 = 0 and x1 = 3:-
y - 0 = 3(x - 3)

y = 3x - 9 is the answer Its D.
