Answer:
5 seconds
1220 ft
Step-by-step explanation:
Step 1: Know when the stone reaches the maximum height
We know the maximum or minimum height of a parabola is at the vertex so we need to find the vertex
Step 2: Calculate the vertex
The t coordinate of the vertex can be calculated with 
b = 160
a = 16

Step 3: We know the t coordinate we can find the height at that time

Therefore the stone reaches its maximum height of 1220 ft in 5 secs

- Solving systems of equations by graphing
Step-by-step explanation:
If the lines are parallel, they will have no solutions.
If the lines are the same, they will have infinite solutions.
If the lines are anything else, they will usually have 1 solution.
If we graph the systems of equations, we see that the lines are parallel.
∴ the systems has no solution.
Answer:
7. about 41.8 degrees or 0.72972 radians (used
, because the given leg is opposite from the angle)
8. about 50.4 degrees or 0.87946 radians (used
)
9. about 12.8 degrees or 0.224 radians (used
)
10. about 51.3 degrees or 0.8957 radians (used
, given leg is opposite from angle)
Step-by-step explanation:
S.O.H.--C.A.H.--T.O.A
sine = opposite (to angle)/hypotenuse
cosine = adjacent (to angle)/hypotenuse
tangent = opposite (to angle)/adjacent (to angle)
I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!
To find the slope of the line, simply remember the basic equation for the slope intercept.
Y = mx +/- b
Where m = slope or rise/run
b = y intercept.
In this case the slope is a negative value and is -5/2.
