This is the fundamental zero additive rule
x - 0 = x
which means that for the set of real numbers, there exist a number such that if added (or subtracted) from any other will not affect such number.
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.
Sixty eight and nine plus eleven equals 12
Your question is missing an important value. That is the number of people on this trip. So we assume that 250 people are on this trip.
Answer:
88 persons
Step-by-step explanation:
Be cause your question does not have the total number of people on this trip, I assumed that the number of people should be 250.
Now we are to find 35% of 250.
This would give the total number of people they enjoyed the trip
0.35 x 250
= 87.5
approximately 88 persons
So we say that 88 persons loved the zoo.
To trick is to find 35% of whatever number of people are on this field trip.
