Answer:
t = 350
Step-by-step explanation:
subtract 250 from each side, and then you'll have t = 350
Answer:
5 2/6
Step-by-step explanation:
you have to mutiply
For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.
Answer:
4920
7084800
2585952000
Step-by-step explanation:
82 chirps = 1 minute
We have 60 minutes in one hour, so 82 x 60 =4920 chirps in one hour
In 24 hours we have 60x24 = 1440 minutes and in one minutes we have 4920 chirps,
Therefore 4920 x 1440 mins =7084800 chirps in one day .
There are 365 days in a year and in one day the cricket chirps 7084800, so 365 days x 7084800 = 258595200 chirps in a year
