The equation gives the speed at impact, V metres per second, of an object dropped from a height of h metres. SHOW WORK From what

devlian [24]

Answer:

h = 17.65 m

Step-by-step explanation:

The given equation gives the speed at impact :

$v=\sqrt{2gh}$

h is height form where the object is dropped

Put v = 18.6 m/s in the above equation.

$h=\dfrac{v^2}{2g}\\\\h=\dfrac{(18.6)^2}{2\times 9.8}\\\\h=17.65\ m$

So, the object must be dropped from a height of 17.65 m.

Given triangle ABC with m M

sammy [17]

9514 1404 393

Answer:

49°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

∠A +∠B +∠C = 180

(x +32) +(x +41) +(3x +22) = 180 . . . . angles assumed to be in degrees

5x +95 = 180

5x = 85

x = 17

x +32 = 49 . . . . measure of ∠A
