Shortest distance to the origin y=1/2x^2 -4

Mathematics

X=0 y=-2
y=0 x=4

The shortest distance has to be the perp bisector from origin to the midpoint of the line.
midpoint =(2,-1)  and distance from the (0,0) origin is sqrt(5) hence, sqrt(5).

What is x=? I got part a but what does x=?
Oksi-84 [34.3K]

Answer:

I think x = 44°

Step-by-step explanation:

Finding the exterior angle:

180° - 45° = 135°

We know that x is multiplied by 3 (3x) so we divide 135 by 3.

135° / 3 = 45°

We know that we have to add 3° to the product of 3x, so we know the product of 3x will be less than 135°. The product should be 135° after 3° is added to it.

Trying a few possible answers:

43° × 3 = 129°

129° + 3° = 132°

That one wasn't quite right.

44° × 3 = 132°

132° + 3° = 135°

What is the value of x?
Lerok [7]

Answer:

  3√2

Step-by-step explanation:

The hypotenuse of an isosceles right triangle is √2 times the side length.

  x = 3√2

_____

All these triangles are similar, so the ratio of hypotenuse to leg is the same for all.

  hypotenuse/leg = x/3 = (3+3)/x

  x² = 3·6 = 3²·2 . . . . cross multiply (identify square factors)

  x = 3√2 . . . . . take the square root
