Setting y = 0, and solving for x, 0 = -.017x^2 + 0.55x, x= 0 and 32.35 feet
The vertex is its highest vertical height. Using the x coordinate of the vertex which is -b/2a, this is .55/(2*0.17 = 16.17 or 1/2 the horizontal distance, it maximum height is 4.45 feet = f(16.17)
Answer:
2 2/7 + 4 1/2
Step-by-step explanation:
Exact form 95/14 for me
Mixed number will be 6 11/14
Answer:
80°
Step-by-step explanation:
The sum of the interior angles in a hexagon is 720°. This means that:
y + (2y - 20) + (2y - 20) + y + (2y - 20) + (2y - 20) = 720° - we can simplify this
10y - 80 = 720° - now, add 80 to both sides
10y = 800 - finally, divide both sides by 10
y = 800 ÷ 8 = 80°
Hope this helps!
Use a calculator i don't know
Well first off lets subtract 7 from 11.2, that gives us 4.2 so we know it has walked 1 minute so far...and now we divide 4.2 from 7 which gives us 0.6 so it has walked 1 minute and 36 seconds
