Answer:

you would have to add 4 to 5 and x but since i dont know what x is, it would be 9x until you find out what x is-

Step-by-step explanation:

ex: if x is like- 3, then it would be 5(3)+4, soon being 9(7)

and THEN you would multiply 7 by 9, leaving you with 64- im SO sorry if this didnt help, but have a fantastic day <3

You use the tan/cos/sin rules

So we know that the hypotenuse=46.8, opposite=44

We can use sin (negative) to find it

sin^-1=opp/hyp
sin^-1=44/66.8
=70 degrees

Hope this helps!! :)

27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.

ololo11 [35]

The polar equation will be $r=\dfrac{4}{1+cos\theta}$

<h3> What is the polar equation?</h3>

A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.

From the equation, we are told that

The Eccentricity: e = 1

The Directrix is y = 4

Generally, the polar equation for e = 1 and y = + c is mathematically represented as

$r =\dfrac{e\times c}{1+ecos\theta}$
