Answer:

The values of x are 60 and 120 degrees respectively

Step-by-step explanation:

In this question, we are asked to give the all the values of x if sin(x) = √3/2

Now, to get these values, we need to know the quadrants in which we have the sine as positive.

We have the sine positive on only two quadrants, these are the first and second quadrants only.

For the first quadrant, the value of x is just x. Meaning an arc sine can simply give us the value of x.

For the second quadrant, we have 180-x, this will give us the value of the angle that gives the same answer in that quadrant.

Let’s calculate!

sin x = √3/2

x = arc sin (√3/2)

x = 60 degrees on the first quadrant.

For the second value, we have the value to be 180 - 60 = 120

Let P be the parabola with focus (0,4) and directrix y=x.Write an equation whose graph is a parabola with a vertical directrix t

prisoha [69]

Answer:

y²=4√2.x

Step-by-step explanation:

The focus is at (0,4) and directrix is y=x or x-y =0, for a parabola P.

The distance between the focus and the directrix of the parabola P is

$\frac{ |0-4| }{\sqrt{(1)^{2}+(-1)^{2} } }$ = $\frac{4}{\sqrt{2} }$

{Since the perpendicular distance of a point (x1, y1) from the straight line ax+by+c =0 is given by $\frac{ |ax1+by1+c| }{\sqrt{a^{2}+b^{2} } }$ }

Let us assume that the equation of the parabola which is congruent with parabola P is y²=4ax

{Since the parabola has vertical directrix}

Hence, the distance between focus and the directrix is 2a = $\frac{4}{\sqrt{2} }$ , {Two parabolas are congruent when the distances between their focus and the directrix are same}

⇒ a=√2

Therefore, the equation of the parabola is y²=4√2.x (Answer)

Carolyn is planning a community garden she would like the length of the garden to be 4 feet more than its width. Carolyn wants t

SCORPION-xisa [38]

Let's make the width 'x'.

And the length 'x+4'.

Perimeter is adding up ALL the sides.

Add: x + x + 4 + x + x + 4.

Simplify:

x + x + 4 + x + x + 4 = 4x + 8
