A straight angle was formed when Tanisha arranged the three angles. This shows that the sum of the measures of the three angles in the triangle is equal to the straight angle, that is, the angle sum is 180 degrees. Also, this shows that whatever the position of the three sides of the triangle is, the total degrees of the angles is always 180.

A parabola has a focus of F(2, -0.5) and a directrix of y=-1.5 P(x,y) represents any point on the parabola, while D(x, -1.5) rep

prohojiy [21]

The sketch of the parabola is attached below

We have the focus $(a,b) = (2, -0.5)$
The point $P(x,y)$
The directrix, c at $y=-1.5$

The steps to find the equation of the parabola are as follows

Step 1
Find the distance between the focus and the point P using Pythagoras. We have two coordinates; $(2, -0.5)$ and $(x,y)$ .
We need the vertical and horizontal distances to find the hypotenuse (the diagram is shown in the second diagram).
The distance between the focus and point P is given by
$\sqrt{ (x-a)^{2}+ (y-b)^{2} }$

Step 2
Find the distance between the point P to the directrix $c$ . It is a vertical distance between y and c, expressed as $y-c$

Step 3
The equation of parabola is then given as
$\sqrt{ (x-a)^{2}+ (y-b)^{2} }$ = $y-c$
$(x-a)^{2}+ (y-b)^{2}= (y-c)^{2}$ ⇒ substituting a, b and c
$(x-2)^{2}+ (y--0.5)^{2} = (y--1.5)^{2}$
$(x-2)^{2}+ (y+0.5)^{2}= (y+1.5)^{2}$ ⇒Rearranging and making $y$ the subject gives

$y= \frac{ x^{2} }{2} -2x+1$

Answer for: -10 = 10 = 7m. m = •0 •7 •10 •11

wel

Answer:

Ok so your answer should be m = 0

Step-by-step explanation:

the explanation is to Rewrite the equation as − 10 +7 m = − 10 .− 10 + 7 m = − 10

Move all terms not containing m

to the right side of the equation.

7 m = 0

Divide each term by 7

and simplify.

m = 0

i hope this can help
