For each of the described curves, decide if the curve would be more easily given by a polar equation or a Cartesian equation. Th

lawyer [7]

Answer:

a) $y=\sqrt{3}\ (x)$ is the equation of the curve that makes an angle π/3.

b) $x=3$ is the equation of line through the point (4,4).

Step-by-step explanation:

Given:

A line from origin which makes an angle of $\frac{\pi }{3}$ with x-axis.

A vertical line from $(4,4)$ .

We have to write the equation of the curves in Polar or Cartesian format.

Step wise:

a) A line from origin which makes an angle of $\frac{\pi }{3}$ with x-axis.

To write the equation of the above line in Polar coordinates is more desirable as the angles could be defined well in polar form.

So,

⇒ $y=mx$ ...equation (i)

⇒ $m=\frac{y}{x}$ ...here $m$ is the slope

The slope in terms of $\theta$ (angle) can be written as,

⇒ $tan(\theta)=\frac{y}{x}$

Plugging the values of the angle, $\theta =\frac{\pi }{3}$ .

⇒ $tan(\theta) =\frac{\pi}{3} = \sqrt{3}$ ...equation (ii)

Now re-arranging the equation (i) we can write it as,

⇒ $y=\sqrt{3}\ (x)$

b) A vertical line from $(4,4)$ .

<em>Note:</em>

<em>The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept .</em>

To write the above point in Cartesian coordinate is more acceptable and easy for us.

⇒ $x=4$

Then,

y = sq-rt(3) x is the equation of the curve that makes an angle π/3.

and x = 3 is the equation of line through the point (4,4).

40% of the students passed both exams. 80% of the students passed the second exam. how many students (in percent) who passed the

navik [9.2K]

50%. students (in percent) who passed the second exam also passed the first exam.

Let's imagine that there are 100 kids in the teacher's class. We know that 40 of them passed BOTH tests, and 80 passed the second test.

Because if they weren't, they wouldn't have passed the first test and consequently wouldn't have passed both, we can be sure that the group of students who passed BOTH tests is only made up of the 80 who passed the second test.

Thus, both tests were passed by 40 of the 80 pupils who passed the second one:

40/80 = 1/2 = 50%.
