The rate of change is about 1 mm.
Answer:
5.12 seconds to the nearest hundredth.
Step-by-step explanation:
When the ball hits the ground h = 0 so
-16t^2 + 81t + 5 = 0
t = [ -81 +/- sqrt ((81^2 - 4 * -16 * 5)]/ (2*-16)
= (-81 +/- sqrt 6881) / -32
= 5.12 , -0.6
So the answer is 5.123 seconds.
Answer:
Step-by-step explanation:
okay so i’m not 100% sure on how to do this but i think you can just add the two together? like 15 + 21 + b. like that’s be 36b. so i’m not sure if that’s how you do it but i think you can do it that way?
Answer:
Step-by-step explanation:
set up a proportion using minutes/mile:
2/(1 1/4) = x/(1 1/2)
2/(5/4) = x/(3/2)
(5/4)x = (3/2)(2)
(5/4)x = 3
x = 3(4/5)
x = 12/5
x = 2 2/5 minutes
pls mark me the brainliest pls
Convert fraction to decimals = divide the numerator by the denominator
3/11 = 0.272727...
