Me to I was doing the work but just lost it I will try again
Answer:
120 minutes
Step-by-step explanation:
D=it 14/7 is 2, multiply 2 by 60 you get 120
Answer:
2x+3y+5
Step-by-step explanation:
Firstly, we remove the parenthesis since there is nothing in front of it.
There is a “+” sign in front of the parenthesis, it stays the same.
Secondly, we combine like terms. We combine the x’s, the y’s, and the normal numbers without a variable.
Finally, after combining the like terms. You end up with “2x+3y+5”.

Step-by-step explanation:
<u>Part A</u>
The average rate of change of a function over the interval ![[a,b]](https://tex.z-dn.net/?f=%5Ba%2Cb%5D)
is equal to 
, hence:
Therefore, the average rate of change of 
over the interval ![[5,9]](https://tex.z-dn.net/?f=%5B5%2C9%5D)
is 
.
<u>Part B</u>
Do the same thing as in Part A:
Therefore, the average rate of change of 
over the interval ![[0.25,1]](https://tex.z-dn.net/?f=%5B0.25%2C1%5D)
is 
.
<u>Part C</u>
To interpret our answer from Part B in terms of the real world it represents, we say that between 0.25 seconds and 1 second, the ball falls at a rate of 4 feet per second (since our average rate of change is negative).
Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.
The 3 inside angles of a triangle must equal 180 degrees.
The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.
Since the 2 bottom angles would be the same, divide 142 by 2 to get x.
X = 142 / 2 = 71 degrees.
