Answer:
At both 0.78 and 1.3 seconds, to the nearest hundredth, the ball will be at 20 feet.
Step-by-step explanation:
We can use two approaches to finding the answer: Calculation and Graphing.
<u>Calculation:</u>
Set h to 20 feet and solve the equation using the quadratic formula.
h= 4 + 33t - 16t^2
20= 4 + 33t - 16t^2
- 16t^2 + 33t + 4 = 20
- 16t^2 + 33t + -16 = 0
Solve using the quadratic formula. I find solutions of 0.779 and 1.28 seconds.
<u>Graphing:</u>
See the attached graph.
The ball is at 20 feet at 0.783 seconds on the way up and 1.28 seconds on the way back down.
===
Both approaches agree: 0.78 and 1.3 seconds, to the nearest hundredth, the ball will be at 20 feet.
Answer:
Rate of snow fall per hour ≥ 1 inches per hour
Step-by-step explanation:
Given:
Amount of snow already settled = 4 inches
Time period of snow fall = 2 hour
New amount of snow = least 6 inches
Computation:
Extra amount of snow ≥ New amount of snow - Amount of snow already settled
Extra amount of snow ≥ 6 - 4
Extra amount of snow ≥ 2 inches
Rate of snow fall per hour ≥ Extra amount of snow / Time period of snow fall
Rate of snow fall per hour ≥ 2 / 2
Rate of snow fall per hour ≥ 1 inches per hour
Lets find the common demoninator of them all, Its 30! so 1/3 of 30= 10
3/5 of 30= 18 7/10 of 30= 21 1/2 of 30 = 15
So that means that 7/10 is the biggest out of them all, That means carlos ran the greatest distance!
