We are given function: y= 
Where, x is the number of hours after 5a.m.
We need to approximates the number of people standing in line to catch a commuter train at 7 a.m.
From 5 a.m. to 7 a.m. total number of hours = 7-5 = 2 hours.
So, we need to plug x=2 in the given function.
Plugging x=2 in
, we get

Let us simplify it now.
2^2= 4.
Therefore,

= -20.524 + 63.642 - 3.333.
= 39.785 or 40 approximately.
Therefore, the number of people in line at 7 a.m. is approximately 40 people.
Option D.40 is correct option.
Answer:
<h2>A = 52.5 m²</h2>
Step-by-step explanation:
The formula of an area of a kite:

<em>e, f</em><em> - diagonals</em>
<em />
We have <em>e = 15m, f = 7m.</em>
Substitute:

the ball reaches its maximum height of 15 feet in 2.2 seconds
The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground
The ball starts on the ground at 0 seconds so the ball starts at x=0 seconds
the ball reaches its maximum height of 15 feet in 2.2 seconds
So it takes 2.2 second to reach the maximum height
It will take another 2.2 seconds to reach the ground
The time the ball in the air is 2.2 + 2.2 = 4.4
The ball will reach the ground in 4.4 seconds
So the domain for g(x) is {0,4.4}
Answer:
16 x 16 = 256
Step-by-step explanation:
So 256 might be the answer? this is confusing but are you on IXL?
To convert an improper fraction into a mixed number, you must find how many times the denominator fits into the numerator cleanly.
58/7
=8.385
It fits in 8 times.
8*7=56
58-56=2
There is a remainder of 2.
The Mixed number would be 8 2/7.
Hope this helps!
