This is the process I would use:

Maddy's = 2x 2x+x=15
Meg's = x 3x=15
x=5

Since Maddy's is 2x, multiply the 5 times 2 and you find that Maddy has 10 stickers.

The lines are perpendicular. Find the slope-intercept form of the equation of line y₂

Alex17521 [72]

When you want to find the slope of the perpendicular line, all you have to do is flip the known slope upside down and make it negative. You know that $y_{1} 's$ slope is 3 and you know $y_{2}$ is perpendicular. So, just flip 3 upside down into $\frac{1}{3}$ and then make it negative, -<span> $\frac{1}{3}$ . If you look at the coordinate grid, you can see that $y_{2}$ crosses the y-axis at 4. When you put those into slope-intercept form you get $y_{2}$ = -</span> $\frac{1}{3}$ x + 4.

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.
