Answer: 6

Step-by-step explanation:

Let use the subsitution method . Look at 11=x+y let get y on the side by itself. 11=x+y 11-x=y Then we are going to subsitute 11-x for y in the top equation so it look like 20.00=2.50x+1.00(11-x). 20.00 =2.50x+11-x. Let simplify and we get 1.50x+11=20. Subtract 11 from both sides we get 1.50x=9. Divide 1.5 by 9 and we get x= 6.

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.
