Answer:
8 hours.
Step-by-step explanation:
80 = 12 + 8.5t where t is the time rented in hours
8.5t = 80 - 12 = 68
t = 68/8.5
= 8 hours.
Answer:
Step-by-step explanation:
A 2-column table with 8 rows. Column 1 is labeled Step with entries 1, 2, 3, 4, 5, 6, 7, 8. Column 2 is labeled Statement with entries cosine (2 x) = 1 minus 2 sine squared (x), let 2 x = theta, then x = StartFraction theta Over 2 EndFraction, cosine (theta) = 1 minus 2 sine squared (StartFraction theta Over 2 EndFraction), negative 1 + cosine (theta) = negative 2 sine squared (StartFraction theta Over 2 EndFraction), 1 + cosine (theta) = 2 sine squared (StartFraction theta Over 2 EndFraction), StartFraction 1 minus cosine (theta) Over 2 EndFraction = sine squared (StartFraction theta Over 2 EndFraction), sine (StartFraction theta Over 2 EndFraction) = plus-or-minus StartRoot StartFraction 1 minus cosine (theta) Over 2 EndFraction EndRoot.
Which step contains an error?
Answer:
Step-by-step explanation:
For this case we have that by definition, the equation of the line in a slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following equation:
Thus, the slope is 
By definition, if two lines are perpendicular then the product of the slopes is -1.
We find
Thus, the equation of the line is:
We substitute the given point to find "b":
Thus, the equation of a line perpendicular to the given line and passing through the given point is:
