Rearrange the formula S = a (a - r) for r.

I'm assuming you're trying to solve for r.
First divide a to both sides
Now you have \frac{S}{a} = a - r
Subtract a to both sides.
And then divide by -1 to both sides.
Now your equation is -\frac{S}{a} + a = r

Expand: a^2 - ar

S= a^2 -ar

S+ ar = a^2

Ar = a^2 - S

R = a^2 - S/ a

In what direction and by how many units is the graph of f(x) = −7 sin(3x + π) − 2 vertically and horizontally shifted?
aev [14]

Answer:

Option 1. Down 2, right pi over 3.

Step-by-step explanation:

In a given function f(x) = -7 sin(3x+π)-2 we have to find the shift horizontally and vertically.

As we know  in a sine equation represented as y = a sin(bx+c) +d

Amplitude of the wave = a

Period = \frac{2\pi }{b}

Horizontal shift = \frac{\pi }{b}

Vertical shift = d

From the given sine function we can get the following values

a = 7

period = \frac{2\pi }{3}

horizontal shift = \frac{\pi }{3} in the right side since it's with positive sign.

Vertical shift = -2 down with 2 ( since it's with negative sign)

Therefore Option 1 is the correct one.

Which calculator correctly shows the quotient of 6.47x10^-15/3.36x10^-29
Alex73 [517]
<h2>Answer:</h2>

\boxed{1.92559524e+14}

<h2>Step-by-step explanation:</h2>

Scientific notation is a special way we choose for writing numbers. So the numers 6.47\times 10^{-15} \ and \ 3.36\times 10^{-29} are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:

\frac{6.47}{3.36}\times 10^{[-15-(-29)]}=1.92559524\times 10^{(-15+29)} \\ \\ \therefore 1.92559524\times 10^{14} \ or \ \boxed{1.92559524e+14}

The division has been performed using the rules for operation with exponentiation.
