Answer:
- h(t) = -16t^2 +188
- 3.4 seconds
Step-by-step explanation:
The usual equation for ballistic motion is ...
h(t) = -16t^2 +v0·t +s0
where v0 is the initial upward velocity, and s0 is the initial height above some reference point.
Here, we presume there is no initial vertical velocity, and the height is given as 188 ft above the river. Since we want the time to reach the river, we're solving ...
h(t) = -16t^2 +188
h(t) = 0
-16t^2 +188 = 0
t^2 -11.75 = 0
t = √11.75 ≈ 3.4
It takes about 3.4 seconds for the log to reach the river.
Answer:
xy < 60
Where x is the amount of subscription per month and y is the number of months
Step-by-step explanation:
Given Anna wants to spend less than $60 for the subscription
Let the amount of subscription per month be x
Let the number of months which Anna can enjoy her music be y
The total amount of money spent by Anna on subscription = ( The amount of subscription per month )( Number of months )
Total amount = xy
Given total amount < 60
So xy < 60
Therefore the above is the inequality recquired.
Answer:
The example is telling you to first add up each number then divide by the amount of numbers that are present in the set. There are four in this example.
Secondly the difference between each data point will differ from each number. Basically subtract the sum from each number. Which is 5 in this case. But if its negative flip it to a positive.
Then add up each absolute value and divide by 4 twice.
