Polar form: (r,θ)

Using these formulas:

x²+y²=r²

tan(θ)=y/x

We have the point (1,1) in cartesian coordinates. We need to find r and θ to get it in polar form.

r²=1²+1²

r²=2

r=±√2

tan(θ)=1/1

tan(θ)=1

θ=π/4 radians or 45 degrees

Polar coordinates: (√2,π/4)

Those answer choices look strange. Are you sure these are the right answer choices?

Answer:

Step-by-step explanation:

The way I see it, (1, 1) corresponds to a point which is √2 units from the origin and has an angle of 45° (or π/4 radians).

pychu [463]

Answer:

d

Step-by-step explanation:

This is point-slope form, and these coordinates make both sides equal to 0.

Discuss some ways that the concepts of covariance and correlation are similar or different.
natima [27]

Answer:

Step-by-step explanation:

<em>Key Differences Between Covariance and Correlation </em>

<em>The following points are noteworthy so far as the difference between covariance and correlation is concerned: </em>

<em> </em>

<em>1. A measure used to indicate the extent to which two random variables change in tandem is known as covariance. A measure used to represent how strongly two random variables are related known as correlation. </em>

<em>2. Covariance is nothing but a measure of correlation. On the contrary, correlation refers to the scaled form of covariance. </em>

<em>3. The value of correlation takes place between -1 and +1. Conversely, the value of covariance lies between -∞ and +∞. </em>

<em>4. Covariance is affected by the change in scale, i.e. if all the value of one variable is multiplied by a constant and all the value of another variable are multiplied, by a similar or different constant, then the covariance is changed. As against this, correlation is not influenced by the change in scale. </em>

<em>5. Correlation is dimensionless, i.e. it is a unit-free measure of the relationship between variables. Unlike covariance, where the value is obtained by the product of the units of the two variables. </em>

(9^(3))^(3) =<br> 9 9<br> 9 0<br> 9 6<br> 81
zmey [24]

Step-by-step explanation:

\because \:  ( {a}^{m} )^{n}  =  {a}^{m \times n}  \\  \\ \therefore ( {9}^{3} )^{3}  =  {9}^{3 \times 3}  =  {9}^{9}  \\

Assuming you are a business owner with different shareholders. How may zero growth stock valuation and constant stock valuation
Katarina [22]

The ways that zero growth stock valuation can affect business operations is that:

  • When zero-growth model states that the dividend is at the same rate, it shows that one has no measure of growth in terms of dividends. This therefore  shows that stock price is equal to the annual dividends and divided also by the needed  rate of return.

<h3>What ways does constant stock valuation affect business operations?</h3>

The Constant  stock valuation  is known to be a kind of share evaluation as it states that the dividends paid by a firm will consistently increase at a constant growth rate.

This will help one to know especially investors on how to set or know the fair price that one needs to pay for a stock on daily basis today by due to future dividend payments.

The overall statement is that  stock value affect one's business operations as  the company's stock price is one that shows an investor perception of their capability to get profit and also if they can grow their profits in terms of future times.
