Find the equation of the parabola whose vertex is the origin and whose directrix is x = -4

lapo4ka [179]

Try this option:

1) if V(0;0) and x= -4, then common view of the required equiation is:

(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;

2) if the V(0;0), then h=k=0 and the required equiation is:

y²=4px;

3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:

y²= -16x

answer: y²= -16x

Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A \sqrt4, 10,

Vika [28.1K]

Answer:

(C)

Step-by-step explanation:

In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.

A. $\sqrt{4}$ , 10 and 116

According to Pythagoras theorem,

⇒ $(116)^2=4+100$

⇒ $13456=104$

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

B. 3,6 and 8

According to Pythagoras theorem,

⇒ $(8)^{2}=(3)^2+(6)^2$

⇒ $64=9+36$

⇒ $64=45$

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

C. 30, 40 and 50

According to Pythagoras theorem,

⇒ $(50)^{2}=(30)^2+(40)^2$

⇒ $2500=900+1600$

⇒ $2500=2500$

which satisfies the condition, therefore theses side lengths form right triangle.
