16. is y=1/2x-3
17. is y=-3/5x+4
18. is y=3/2x-3 :)
Answer:
<em>For each horizontal foot, the roller coaster changes </em><em>6 feet</em><em> of height.</em>
Step-by-step explanation:
Across a horizontal distance of 25 feet, a roller coaster has a steep drop.
So the run is 25 feet.
The height of the roller coaster at the bottom of the drop is -150 feet. (Negative sign is given because it is measured from the top to bottom)
So the rise is 150 feet.
The slope of the roller coaster is,
Slope of 6 means, for 1 unit of run, the object has a rise of 6 units.
Therefore, for each horizontal foot, the roller coaster changes 6 feet of height.
Answer: 7cm
Step-by-step explanation:
Use pythagorean theorum:
Variables:
Let the edge = A
Face diagonal (F) = 10cm
Inner diagonal (I) = sqrt(150) cm
A^2 = I^2 - F^2
A^2 = [sqrt(150)]^2 - 10^2
A^2 = 150 - 100
A^2 = 50
A = sqrt(50)
A = 7.0710678 cm
A = 7cm (to the nearest tenth)
so, length of an edge = 7cm
I would so go with B I'm not sure if that's the correct answer though but that's what I would go with
